As 2025 draws to a close, the regulatory landscape is shifting from a period of "planning and grace" to one of "strict enforcement." The upcoming year will be a milestone for cybersecurity and privacy, with massive frameworks like the EU AI Act and the Cyber Resilience Act moving into their critical enforcement phases, while a new wave of U.S. state privacy laws goes live.
To ensure your organization enters 2026 on a secure footing, we have compiled an essential end-of-year compliance checklist. This review will help you move beyond reactive patching and toward a state of continuous, audit-ready resilience.
1. Governance: Update Your Privacy Framework
On January 1, 2026, new comprehensive privacy laws in Indiana, Kentucky, and Rhode Island will go into effect. Simultaneously, many existing state laws (such as those in Oregon and Connecticut) will begin mandating the recognition of Universal Opt-Out Mechanisms (like Global Privacy Control).
- Inventory and Map Data: Ensure you know where PII from residents of these new states is stored.
- Update Privacy Notices: Your public-facing policies must reflect the rights of these new jurisdictions and clearly state how you handle opt-out signals.
- Automate DSARs: Verify that your Data Subject Access Request (DSAR) workflow can handle the 2026 influx of requests within the statutory 30-to-45-day timelines.
2. Identity and Access: Audit the "New Perimeter"
Identity continues to be the primary attack vector. Reviewing your Identity and Access Management (IAM) posture is a prerequisite for SOC 2, ISO 27001, and DORA compliance.
- Review Permissions: Conduct a "User Access Review" to ensure the principle of least privilege. Revoke access for any offboarded employees or contractors and remove unnecessary administrative rights.
- Enforce MFA Everywhere: Confirm that Multi-Factor Authentication (MFA) is active for 100% of your staff and third-party contractors, particularly for cloud consoles and VPNs.
- Audit Non-Human Identities: Don't forget service accounts, API keys, and automated bots. These are often overlooked in manual reviews but are high-value targets for attackers.
3. AI Governance: Prepare for the EU AI Act
If your organization develops or deploys AI systems within the EU, August 2, 2026, is your most critical deadline. This is when the transparency rules and obligations for high-risk AI systems become fully applicable.
- Classify AI Systems: Perform a mapping exercise to determine if your AI use cases fall into the "Prohibited," "High-Risk," or "Limited Risk" categories.
- Implement Transparency Controls: Ensure that AI-generated content is clearly labeled and that users are notified when they are interacting with an AI system.
- Draft Technical Documentation: Start building the required technical documentation and risk management frameworks for high-risk systems now, as these are often the most time-intensive requirements.
4. Product Security: Align with the Cyber Resilience Act (CRA)
For manufacturers and software developers selling in the EU, the reporting obligations of the Cyber Resilience Act begin on September 11, 2026.
- Establish Incident Reporting: Ensure you have a process to report actively exploited vulnerabilities to ENISA within 24 hours of discovery.
- Inventory Your SBOM: Maintain a Software Bill of Materials (SBOM) for all digital products to ensure you can quickly identify and remediate vulnerabilities in third-party components.
5. Vendor Risk Management: Close the Supply Chain Gaps
In 2026, regulators like the SEC (under the updated Regulation S-P) and FINRA will place even greater emphasis on how organizations monitor their third-party service providers.
- Review Critical Vendor Certifications: Collect updated SOC 2 Type 2 or ISO 27001 reports from your "Tier 1" vendors.
- Audit Fourth-Party Risk: Understand who your vendors are using. A breach at a sub-processor (a "fourth party") can be just as damaging and legally complex as a direct breach.
- Test Contractual Alignment: Verify that your vendor contracts include necessary data protection and breach notification clauses that align with your 2026 regulatory obligations.
6. Resilience Testing: Beyond the "Checklist" Audit
With DORA and CIRCIA (Cyber Incident Reporting for Critical Infrastructure Act) moving into full oversight mode, 2026 is the year of operational resilience.
- Run Tabletop Exercises: Conduct a cross-departmental incident response simulation. Does the executive team know their role? Is legal ready to handle a 72-hour reporting window?
- Verify Backup Integrity: Don’t just check that the "backup was successful." Perform a full restoration of a critical system to ensure your Recovery Time Objective (RTO) is actually achievable.
Conclusion: Starting 2026 with Confidence
A successful end-of-year review is about more than just checking boxes; it’s about identifying the strategic gaps that could disrupt your business in the coming year. By addressing these six areas now, you transform compliance from a year-end burden into a foundation for growth and trust.
Compliance is a continuous journey. Taking these steps today ensures your organization is not only ready for the audits of 2026 but is inherently more secure against the evolving threat landscape.
