API Security Compliance: Standards, Controls & Best Practices

APIs increasingly expose sensitive data, financial transactions, business processes and privileged application functions. As organisations connect more applications, partners, users and machine identities through APIs, security cannot depend on isolated technical controls alone.

Authentication, authorization, encryption, API gateways and security testing can reduce risk, but their existence does not automatically establish API security compliance. Organisations must understand which requirements apply, translate those requirements into repeatable controls, assign accountability and maintain evidence that those controls continue to operate.

That evidence becomes especially important as APIs, identities and permissions change. An access decision that was appropriate six months ago may no longer reflect an employee’s role, an application’s purpose or a service account’s current responsibilities.

A mature compliance programme therefore connects:

Requirements → Controls → Evidence → Audit → Risk → Access Governance → Continuous Compliance

This guide explains how organisations can build that model around APIs without treating compliance as a one-time audit exercise.

What Is API Security Compliance?

API security compliance means aligning APIs with applicable security, regulatory, contractual and organisational requirements and maintaining evidence that required controls are implemented and operating effectively.

Compliance can involve technical controls such as authentication, authorization, data protection and security testing, but it also extends into governance.

Organisations may need to demonstrate:

• Which APIs are in scope
• Who owns them
• What risks they create
• What security controls apply
• Who has access
• Whether access remains appropriate
• How vulnerabilities are remediated
• Whether security activity is monitored
• What evidence supports those controls

API Security vs API Security Compliance

API Security
Protects APIs, data and resources from threats, attacks and unauthorised activity.

API Security Compliance
Demonstrates that applicable security requirements and controls have been implemented, maintained and appropriately evidenced.

An API may technically appear secure while still creating a compliance gap if ownership, access reviews, evidence or required control processes are missing.

Conversely, passing a compliance review should not be interpreted as proof that every API vulnerability or threat has been eliminated.

Why API Security Compliance Matters

APIs often provide direct pathways to valuable systems and information.

That may include:

• Customer information
• Financial records
• Payment data
• Personal information
• Business-critical applications
• Administrative functions
• Third-party services

Consistent API compliance requirements create an organisational baseline for protecting these assets.

Compliance can improve accountability by requiring teams to identify owners, define controls and retain evidence. It can also reduce inconsistency between teams that might otherwise make different decisions about authentication, authorization, monitoring or security testing.

The importance grows when APIs cross organisational boundaries.

A partner application may need legitimate access today but no longer require that access after an integration changes. A machine identity may remain technically functional while its permissions become unnecessarily broad. A deprecated API may remain reachable even though documentation shows that it should have been retired.

Compliance therefore needs to translate security expectations into repeatable activities.

Compliance should translate security expectations into repeatable controls and evidence.

What Are API Compliance Requirements?

API requirements vary according to the organisation, data involved, contractual obligations and applicable standards.

However, several control areas appear repeatedly.

API Inventory and Ownership Requirements

Organisations should establish which APIs fall within relevant security and compliance scope.

Important information may include:

• API owner
• Business purpose
• Environment
• Version
• Exposure
• Data classification
• Risk level
• Lifecycle status

An incomplete API inventory creates a fundamental problem: security teams cannot consistently apply controls to assets they do not know exist.

Authentication Requirements

Define how users, applications, services and machine identities prove their identity.

Requirements may specify:

• Which APIs require authentication
• Approved authentication mechanisms
• Credential-management expectations
• Stronger controls for privileged functions

Authorization Requirements

Authentication should be followed by explicit access decisions.

Authorization requirements can govern:

• Resources
• Objects
• Functions
• Sensitive properties
• Administrative operations

OWASP’s current API Security Top 10 includes separate risks for Broken Object Level Authorization, Broken Object Property Level Authorization and Broken Function Level Authorization, highlighting why API access decisions need to be enforced at multiple levels.

API Data Protection Requirements

Requirements may address:

• Encryption in transit
• Sensitive-data handling
• Data minimisation
• Secure storage
• Sensitive fields
• Third-party data flows

Logging and Monitoring Requirements

Define which security activities need visibility.

Examples include:

• Authentication failures
• Authorization denials
• Privileged activity
• Security alerts
• Sensitive resource access

Security Testing Requirements

Define expectations around:

• Vulnerability assessment
• API security testing
• Remediation
• Retesting

Access Governance Requirements

Access governance may include:

• Least privilege
• Privileged-access review
• Entitlement reviews
• User access certification
• Machine-identity access review
• Access remediation

API Lifecycle Requirements

Compliance should follow:

Design → Development → Deployment → Change → Deprecation → Retirement

Security obligations should not end when the API reaches production.

API Security Standards That Influence Compliance

Different standards and guidance sources address different parts of API security.

OWASP API Security

The OWASP API Security Project focuses on API-specific vulnerabilities and security risks. Its current API-specific Top 10 edition is the 2023 release. OWASP describes the project as an educational and risk-awareness resource rather than a certification programme.

NIST

NIST SP 800-228 provides dedicated guidance for protecting APIs in cloud-native environments. The current publication includes updates through March 13, 2026 and addresses API risks, pre-runtime controls, runtime protection and a risk-based security approach.

ISO/IEC 27001

ISO/IEC 27001:2022 defines requirements for establishing, implementing, maintaining and continually improving an Information Security Management System. It is not an API-specific standard, but APIs can fall within the organisation’s broader information-security risk-management system.

PCI DSS

PCI DSS establishes baseline technical and operational requirements designed to protect payment account data. It applies according to payment-data scope rather than simply because an organisation happens to operate APIs.

For deeper comparison, see [Internal Link: API Security Standards & Frameworks].

PCI DSS API Security

PCI DSS API security is especially important where APIs are part of environments that store, process or transmit payment account data, or can affect the security of those environments.

PCI SSC currently lists PCI DSS v4.0.1 in its official document library. The Council describes PCI DSS as baseline technical and operational requirements intended to protect payment account data.

When Does PCI DSS Apply to APIs?

Scope can include APIs that:

• Handle payment account data
• Transmit relevant payment data
• Provide access to in-scope systems
• Influence systems affecting payment-data security

PCI SSC states that PCI DSS is intended for entities that store, process or transmit cardholder data or sensitive authentication data, as well as entities that could impact their security.

That means PCI DSS should not automatically be applied to every financial or enterprise API.

What PCI DSS Emphasises for API Security

There is no separate universal “PCI API Security Standard”.

Instead, organisations need to determine how applicable PCI DSS requirements relate to their API environment.

Relevant themes can include:

• Authentication
• Access control
• Secure configuration
• Data protection
• Vulnerability management
• Security testing
• Logging
• Monitoring

PCI SSC also continues to publish supporting guidance around vulnerability-management requirements, including requirements associated with PCI DSS Requirements 6 and 11.

PCI DSS API Access Control

Relevant access-control considerations can include:

• Appropriate authentication
• Restricted privileged access
• Least privilege
• Controlled access to sensitive functions
• Periodic review of permissions where required by the organisation’s control environment

PCI DSS API Security Evidence

Useful evidence may include:

• Security configuration records
• Testing results
• Vulnerability findings
• Remediation records
• Security logs
• Access-review records

The important principle is not simply that a control exists, but that its implementation and operation can be demonstrated.

Core API Security Controls for Compliance

A compliance programme should translate requirements into defined API security controls.

A useful classification is:

Preventive + Detective + Corrective + Governance Controls

API Inventory Controls

Maintain visibility into relevant APIs, versions and owners.

Authentication Controls

Verify human and machine identities before protected access.

Authorization Controls

Restrict identities to appropriate functions, objects and data.

Encryption Controls

Protect sensitive data in transit and, where appropriate, at rest.

Secrets and Credential Controls

Govern:

• API keys
• Tokens
• Certificates
• Service credentials
• Signing keys

Input Validation Controls

Validate expected API input and reject unsafe requests.

Rate and Resource Controls

Reduce resource abuse through appropriate limits or quotas.

Security Testing Controls

Use:

Test → Identify → Remediate → Retest

Monitoring and Logging Controls

Record security events needed for:

• Detection
• Investigation
• Auditability

Access Governance Controls

Review whether identities still require current access.

API Lifecycle Controls

Govern:

• Changes
• Versions
• Deprecation
• Retirement

Technical controls protect the API. Governance controls ensure those protections remain accountable and reviewable.

API Access Control and Compliance

API access control is one of the strongest intersections between technical API security and identity governance.

Authentication identifies who or what is requesting access. Authorization determines what that identity can do. Access governance determines whether the underlying permission should exist at all.

Use:

Identity → Role → Entitlement → Authorization → API Resource

User Access

Employees and contractors can accumulate permissions as they move between roles or projects.

Application Access

Applications may retain permissions after integrations or business requirements change.

Service Account Access

Service accounts often run continuously and may have long-lived permissions.

Machine Identity Access

Machine identities should receive explicit:

• Ownership
• Permission scope
• Credential lifecycle
• Access review

Privileged API Access

Administrative and high-impact access should receive additional scrutiny.

Least Privilege

Permissions should match legitimate current responsibilities.

Periodic Access Reviews

Reviewers should periodically answer:

• Does this identity still require access?
• Does it need every current entitlement?
• Is any access excessive?

SecurEnds currently supports recurring access reviews across applications and consolidated visibility into user entitlements.

Access Remediation

A review creates limited value if inappropriate access remains in place.

Compliance processes should support:

Review → Decide → Remove → Record

API Data Protection for Compliance

API data protection should follow the sensitivity of the information being processed.

Use:

API → Data → Sensitivity → Access → Protection

Protect Data in Transit

Sensitive API traffic should use appropriately encrypted transport.

Protect Sensitive Data at Rest Where Required

Backend storage controls should reflect data sensitivity and applicable requirements.

Minimise API Data Exposure

Return only the information required for the approved request.

Protect Sensitive Fields

Fine-grained authorization may be required to prevent users from reading or modifying restricted properties.

Avoid Sensitive Data in Logs

Logs should not unnecessarily expose:

• Passwords
• API secrets
• Authentication tokens
• Sensitive personal information

Secure Error Responses

Errors should not reveal unnecessary implementation details or sensitive information.

Govern Third-Party Data Sharing

Organisations should understand:

• Which partner receives data
• Why it needs that data
• What access is permitted
• How that relationship is governed

API Security Risk Management

API security risk management connects technical findings to business impact.

A useful lifecycle is:

Identify → Assess → Prioritise → Remediate → Verify

Identify API Assets

Start with visibility.

Classify API Risk

Consider:

• Exposure
• Data sensitivity
• Privilege
• Business criticality

Identify Technical Vulnerabilities

Evaluate areas such as:

• Broken authentication
• Broken authorization
• Misconfiguration
• Input-validation weaknesses
• Resource-control weaknesses

Assess Access Risk

Risk can also come from:

• Excessive permissions
• Stale access
• Privileged users
• Overprivileged service accounts
• Unowned machine identities

Prioritise Remediation

The same technical vulnerability can create very different risk depending on exposure, data and identity privilege.

Track Exceptions and Residual Risk

If remediation cannot occur immediately, document:

• Risk
• Owner
• Compensating controls
• Review date
• Residual exposure

API Security Governance for Compliance

API security governance establishes how controls are owned and managed.

API Ownership

Each critical API should have an accountable owner.

Security Policies

Policies define mandatory requirements.

Control Ownership

Every significant control should have someone responsible for operation and maintenance.

Exception Management

Exceptions should be:

• Documented
• Approved
• Risk-assessed
• Time-bound

API Access Governance

Define who can:

• Approve access
• Review access
• Remove access

API Lifecycle Governance

Assign responsibility for changes, deprecation and retirement.

Evidence Ownership

Someone must own the records required to demonstrate control operation.

The distinction is:

Governance creates the operating model. Compliance demonstrates that the model is being followed.

See [Internal Link: API Security Governance].

What Evidence Is Needed for API Security Compliance?

Compliance requires evidence that goes beyond policy documents.

API Inventory Evidence

Examples include:

• API inventory records
• Owners
• Versions
• Risk classifications
• Lifecycle states

Authentication Evidence

Examples include:

• Approved authentication configurations
• Identity policies
• Credential controls

Authorization Evidence

Examples include:

• Role definitions
• Permission models
• Entitlement records
• Authorization policies

Security Testing Evidence

Maintain:

• Vulnerability-assessment results
• API security-testing records
• Retesting evidence

Remediation Evidence

Track:

• Findings
• Owners
• Actions taken
• Closure dates
• Retest results

Monitoring Evidence

Retain appropriate:

• API logs
• Security alerts
• Incident records
• Investigation outcomes

Access Governance Evidence

Examples include:

• Access-review campaigns
• Certification decisions
• Revocations
• Remediation actions

SecurEnds’ current user-access-review capabilities include recurring campaigns and centralised entitlement review across applications, while its non-human identity capability extends recurring review and ownership processes to service accounts and AI accounts.

Lifecycle Evidence

Maintain records relating to:

• Material API changes
• Deprecated versions
• Credential revocation
• Retirement

The question should always be:

Can the organisation prove that the control operates?

What Is an API Security Audit?

An API security audit evaluates whether defined security requirements, controls and governance processes are implemented and supported by appropriate evidence.

An API security audit is generally more evidence-driven than a broader exploratory security assessment.

API Scope Review

Verify which APIs are included.

Authentication Review

Evaluate authentication expectations and supporting evidence.

Authorization Review

Review permission models and actual access controls.

Data Protection Review

Determine whether sensitive information receives required protection.

API Security Testing Review

Confirm that required testing occurs and findings are addressed.

Logging and Monitoring Review

Evaluate whether required security events are visible and retained.

Access Governance Review

Review:

• User access
• Privileged access
• Service accounts
• Certification evidence
• Remediation

Third-Party API Review

Assess important external integrations where relevant.

API Lifecycle Review

Confirm that obsolete APIs, credentials and permissions are retired appropriately.

API Security Audit Checklist

Scope

• APIs are inventoried.
• Owners are identified.
• Risk classifications are current.

Authentication

• Protected APIs require appropriate authentication.
• Credential controls are documented.

Authorization

• Object-level permissions are enforced.
• Privileged functions are restricted.
• Least privilege is applied.

Data Protection

• Sensitive traffic is appropriately protected.
• Excessive data exposure is controlled.
• Sensitive logging is limited.

Testing

• Security testing occurs.
• Findings are documented.
• Remediation is tracked.
• Fixes are retested.

Monitoring

• Relevant security events are logged.
• Alerting processes exist.
• Required evidence is retained.

Access Governance

• User access is reviewed.
• Privileged access is reviewed.
• Service accounts are governed.
• Remediation is documented.

API Security Compliance Across the API Lifecycle

Compliance should follow the API’s entire lifespan.

API Design

Define security and compliance requirements before implementation.

Development

Build required controls into the API.

Testing

Validate that controls operate correctly.

Deployment

Confirm production configuration and ownership.

Runtime

Monitor security-relevant activity.

Change Management

Reassess control requirements after material changes.

Access Changes

Update permissions when:

• Users change roles
• Applications change purpose
• Service accounts change function

Retirement

Remove:

• API endpoints
• Credentials
• Integrations
• Permissions

NIST SP 800-228’s current edition includes recommended API security controls by lifecycle stage, reinforcing the importance of treating API protection as an ongoing lifecycle process.

Continuous API Security Compliance

Point-in-time compliance becomes unreliable when the underlying environment changes continuously.

Changes can include:

• New APIs
• New API versions
• New third-party integrations
• Employee role changes
• New service accounts
• Permission changes
• New vulnerabilities

This creates the need for continuous API security compliance.

Continuous API Inventory

Keep API visibility current.

Continuous Security Monitoring

Observe significant runtime activity.

Regular API Security Testing

Test according to API risk and change frequency.

Periodic Access Reviews

Revalidate human and machine access.

Continuous Remediation Tracking

Follow findings through closure rather than only recording their existence.

Ongoing Evidence Collection

Collect evidence as part of normal control operation instead of reconstructing it before an audit.

Use:

Control → Monitor → Review → Remediate → Evidence

ISO/IEC 27001:2022 itself is built around establishing, maintaining and continually improving an ISMS, reinforcing the broader principle that security governance should be continuous rather than static.

API Security Compliance vs API Security Governance

API Security Governance	API Security Compliance
Defines policies and ownership	Demonstrates requirements are satisfied
Creates operating processes	Validates process operation
Manages risk and exceptions	Reviews supporting evidence
Governs access	Demonstrates access controls
Establishes the operating model	Provides assurance

The relationship is:

Governance establishes the system. Compliance verifies and evidences it.

For the operating-model perspective, see [Internal Link: API Security Governance].

API Security Compliance vs API Security Assessment

API Security Assessment

Evaluates:

• Current security posture
• Vulnerabilities
• Attack surface
• Architecture
• Identity and access risk
• Monitoring capability

API Security Compliance

Evaluates whether:

• Applicable requirements are defined
• Required controls exist
• Controls operate
• Evidence is maintained

An assessment can reveal gaps that affect compliance, but an assessment is not the same thing as compliance.

For the risk-evaluation process, see [Internal Link: API Security Assessment].

API Security Compliance Best Practices

Maintain a Current API Inventory

Compliance scope begins with visibility.

Define Applicable Requirements Before Implementation

Do not wait for an audit to determine which controls apply.

Assign API and Control Owners

Accountability should be explicit.

Document Authentication and Authorization Requirements

Define both identity verification and resource permission expectations.

Apply Least Privilege

Reduce unnecessary standing access.

Maintain Security Testing Evidence

Retain relevant assessment and retesting records.

Track Vulnerability Remediation

Findings should have owners and closure evidence.

Monitor Security-Relevant API Activity

Ensure important events can support investigation and assurance.

Review Human and Machine Access

Include users, applications and service identities.

Maintain Exception Records

Document risk acceptance and expiry.

Integrate Evidence Collection Into Normal Operations

Avoid audit-time evidence reconstruction.

Reassess After Material API Changes

Changes can alter risk and compliance scope.

Remove Deprecated APIs and Credentials

Retirement should remove technical and access artefacts.

Treat Compliance as Continuous

Controls, identities and evidence all change over time.

Common API Security Compliance Mistakes

Treating Compliance as a Security Guarantee

Compliance demonstrates control against defined requirements. It does not prove that every attack path has been eliminated.

Treating OWASP as a Certification Standard

OWASP API Security is an awareness and risk resource. OWASP states that its API Top 10 aims to educate those involved in API development and maintenance.

Assuming PCI DSS Applies to Every API

PCI DSS scope depends on payment account data and the systems that can affect its security.

Starting With an Incomplete API Inventory

Unknown APIs cannot reliably enter compliance scope.

Focusing Only on Authentication

Authentication does not answer whether an identity should access a specific resource.

Ignoring API Authorization

OWASP’s current API risks demonstrate how frequently authorization problems occur at object, property and function levels.

Ignoring Machine Identities

Service accounts and other non-human identities can retain significant permissions without human interaction.

Failing to Review Access

Access that was appropriate when granted may become excessive.

Collecting Evidence Only Before Audits

Last-minute evidence gathering makes continuous control assurance difficult.

Leaving Deprecated APIs Active

Old versions can remain part of the attack and compliance surface.

Treating Compliance as a One-Time Exercise

APIs, identities, risks and requirements continually change.

How Identity Governance Strengthens API Security Compliance

API security compliance often requires organisations to demonstrate not only that access controls exist, but that access is appropriate, reviewed and removed when it is no longer needed.

This is where identity governance becomes highly relevant.

Identity Visibility

Understand who has access across relevant applications and systems.

Entitlement Visibility

Understand the specific permissions held by each identity.

SecurEnds currently provides application- and entitlement-centric views that help organisations see relevant users, credentials and permissions and identify potentially excessive access.

User Access Reviews

Managers and owners can periodically validate whether access remains justified.

SecurEnds supports recurring user-access-review campaigns across connected applications.

Access Certification

Certification provides evidence that access decisions have been actively reviewed rather than assumed.

Least-Privilege Governance

Access should be reduced to what users, applications and processes genuinely require.

SecurEnds describes least privilege as restricting users, applications and processes to the minimum access needed for their functions.

Privileged Access Review

Higher-risk entitlements should receive additional scrutiny.

Machine and Application Access

Non-human identities need ownership and review as well.

SecurEnds currently supports lifecycle governance for service accounts and AI accounts, including ownership, recurring access review and onboarding/offboarding workflows.

Identity Lifecycle

Permissions should change when roles, employment relationships or system responsibilities change.

Access Remediation

When access is found to be inappropriate, the organisation needs evidence that it was actually removed or adjusted.

The central message is:

API security controls enforce access. Identity governance helps organisations demonstrate that the identities receiving that access remain appropriately authorised over time.

How SecurEnds Supports API Access Governance and Compliance

SecurEnds complements technical API security controls through identity and entitlement governance.

Its verified capabilities include user access reviews, recurring access certification, entitlement visibility, non-human identity governance and access-remediation workflows. SecurEnds can consolidate identity and entitlement information across applications, run recurring review campaigns and support reviewer decisions on whether current access remains appropriate.

For service accounts and other non-human identities, SecurEnds provides visibility into existing access, ownership and recurring review across the identity lifecycle.

These capabilities do not replace API authentication, authorization, gateways, vulnerability testing or technical monitoring.

Instead, they strengthen the access-governance and evidence layer:

Technical API controls + identity governance + evidence = stronger compliance readiness.

This helps organisations demonstrate not only that API access controls exist, but that the permissions behind those controls are being reviewed and remediated over time.

How to Build an API Security Compliance Programme

Step 1 — Identify Applicable Requirements

Determine which regulatory, contractual, organisational and security requirements apply.

Step 2 — Define Compliance Scope

Identify relevant:

• APIs
• Applications
• Data
• Identities
• Environments
• Third parties

Step 3 — Discover and Classify APIs

Build the inventory and establish risk context.

Step 4 — Translate Requirements Into Controls

Convert broad requirements into measurable technical and governance expectations.

Step 5 — Implement Authentication, Authorization and Data Protection

Apply the required preventive controls.

Step 6 — Establish Security Testing and Monitoring

Verify security before deployment and maintain runtime visibility.

Step 7 — Establish Access Governance

Define:

Request → Approval → Access → Review → Certification → Remediation → Removal

Step 8 — Collect Evidence Continuously

Capture evidence as controls operate.

Step 9 — Conduct Assessments and Audits

Use assessments to identify risk and audits to verify defined requirements and evidence.

Step 10 — Remediate Gaps

Assign owners and track corrective actions.

Step 11 — Reassess After Changes

Revisit requirements after material API, access or architecture changes.

The complete model is:

Scope → Requirements → Controls → Evidence → Audit → Remediate → Improve

Conclusion

API security compliance is not a single control, framework or annual audit.

A sustainable programme requires:

API visibility + requirements + technical controls + data protection + risk management + access governance + testing + monitoring + evidence + continuous review

Standards and regulatory requirements establish expectations. Technical controls protect APIs and data. Governance assigns ownership. Security testing and monitoring validate that protections continue to work. Evidence demonstrates that those processes operate.

Access also needs to remain part of the compliance model.

Strong compliance depends on understanding who has access, what entitlements they hold, whether that access remains justified and whether unnecessary permissions are removed.

That is what turns compliance from a point-in-time exercise into a repeatable security operating process.

FAQs

What is API security compliance?

API security compliance is the process of aligning APIs with applicable security, regulatory, contractual and organisational requirements and maintaining evidence that required controls are operating.

It typically covers areas such as inventory, authentication, authorization, data protection, security testing, monitoring, access governance and lifecycle management.

What are the main API compliance requirements?

Common API compliance requirements include API inventory and ownership, authentication, authorization, data protection, logging, security testing, vulnerability remediation, access reviews and lifecycle controls.

The exact requirements depend on the organisation’s risk, data and applicable standards.

Which standards influence API security compliance?

Commonly relevant sources include OWASP API Security, NIST API-security guidance, ISO/IEC 27001 and PCI DSS.

They serve different purposes: OWASP focuses on API-specific security risks, NIST provides risk-based API protection guidance, ISO/IEC 27001 establishes ISMS requirements and PCI DSS addresses payment-account-data security.

Does PCI DSS apply to APIs?

PCI DSS can apply to APIs that store, process or transmit payment account data or can affect the security of systems in the relevant payment environment.

It should not automatically be assumed to apply to every API.

What PCI DSS controls are relevant to API security?

Depending on scope, relevant themes can include authentication, access control, secure configuration, data protection, vulnerability management, security testing, logging and monitoring.

PCI DSS is a broader payment-data security standard rather than a standalone API-specific standard.

What should be reviewed during an API security audit?

An API security audit should review scope, API ownership, authentication, authorization, data protection, testing, remediation, monitoring, access governance, third-party dependencies and API lifecycle evidence.

The key question is whether required controls are both implemented and supported by reliable evidence.

How does identity governance support API security compliance?

Identity governance helps organisations maintain visibility into users, applications, service accounts and entitlements, periodically review whether access remains necessary and record remediation decisions.

That provides evidence that access is not only technically enforced but also governed throughout the identity lifecycle. SecurEnds currently supports recurring access reviews and non-human identity governance for this purpose
