Your 2026 Cybersecurity Year-End Checklist: Five Priorities for a Stronger 2027

Your 2026 Cybersecurity Year-End Checklist: Five Priorities for a Stronger 2027

As 2026 winds down, you probably don't need another massive cybersecurity checklist telling you to enable MFA, install patches, and update your policies.

Those things matter, of course. But year-end is also a good opportunity to step back and ask a bigger question:

What cybersecurity risks are we carrying into 2027, and are we comfortable with them?

Use the end of the year to close out commitments, revisit unresolved risks, clean up unnecessary exposure, and decide where your security efforts should go next.

1. Close Out Your 2026 Commitments

Start with the things your organization has already committed to doing.

Some are obvious deadlines, such as regulatory requirements or cyber insurance renewals. Others may be promises made during an audit, risk assessment, customer review, or leadership meeting that have quietly remained open.

Before year-end, take inventory:

• Review cyber insurance renewal requirements and outstanding recommendations.

• Check regulatory and contractual cybersecurity obligations.

• Review outstanding audit and compliance findings.

• Identify remediation commitments made to customers, leadership, or other stakeholders.

• Determine which items must be completed now and which can legitimately carry into 2027.

One timely example for Oklahoma organizations is the Oklahoma Consumer Data Privacy Act (OCDPA), which takes effect January 1, 2027. While the law doesn't apply to every business, organizations should determine whether they're covered and, if so, use a compliance plan to prepare to meet applicable requirements when the law takes effect. Requirements may affect how organizations collect, retain, and protect personal information, respond to consumer requests, manage third-party relationships, and prepare for security incidents. The time to evaluate these obligations is now, not after the law takes effect.

Not everything needs to be finished by December 31. What matters is understanding what remains open and consciously deciding what happens next.

Ask yourself: What have we committed to doing that still isn't done?

2. Know What Risks You're Carrying Into 2027

This may be the most important exercise on the list.

Pull out your most recent risk assessment, penetration test, vulnerability reports, audit findings, and other security assessments. Look beyond what was discovered and focus on what remains unresolved.

For each significant open risk:

• Does it have an owner?

• Is there a realistic remediation date?

• Do we understand the potential business impact?

• Have we decided how we will address it?

• Does leadership understand significant risks that will remain unresolved?

Remember, an unresolved finding isn't necessarily evidence of poor cybersecurity management. There may be legitimate business, technical, or financial reasons not to remediate something immediately.

The problem is when risks remain unresolved simply because nobody made a decision.

Organizations generally have several options: mitigate the risk by reducing its likelihood or impact, transfer some of the financial consequences through insurance or contractual arrangements, avoid the risk by stopping the activity that creates it, or accept the remaining risk knowingly. The important part is making that decision deliberately, documenting it, assigning appropriate ownership, and revisiting it periodically.

Ask yourself: What significant risks are we knowingly carrying into 2027?

3. Clean Up What You No Longer Need

One of the simplest ways to reduce cybersecurity risk is to reduce what you have to protect.

Organizations accumulate accounts, data, applications, permissions, and third-party connections over time. Individually, they can seem insignificant. Collectively, they increase your attack surface.

Use year-end as an opportunity to review:

• Former employee and contractor accounts.

• Dormant or unnecessary privileged accounts.

• Old vendor and third-party access.

• Excessive permissions to sensitive information.

• Applications and cloud services that are no longer needed.

• Sensitive data that no longer serves a business or retention purpose.

• Forgotten integrations, service accounts, and API access.

The goal isn't cleanup for cleanup's sake. Every unnecessary account, connection, permission, or sensitive file you eliminate is one less thing that can potentially be compromised. And when it comes to sensitive data, there's an additional benefit: information you no longer retain generally can't be exposed in a future breach. Just make sure deletion decisions account for applicable legal, regulatory, and business retention requirements.

Ask yourself: What are we retaining that no longer provides business value?

4. Verify the Controls You're Counting On

There's an important difference between having a security control and knowing that it works.

Your backup dashboard might be green, but when was the last time someone successfully restored important data from it? Your incident response plan may be complete, but has anyone actually exercised it?

Before heading into another year, validate some of the controls you depend on most.

• Test restoration from backups.

• Exercise your incident response plan.

• Verify MFA and privileged-access protections are applied as expected.

• Review whether critical vulnerabilities are being remediated within your expected timelines.

• Retest significant penetration-test findings after remediation.

You don't necessarily need to retest everything. Concentrate on controls and vulnerabilities where failure would have a meaningful business impact.

Ask yourself: Which security controls are we assuming work but haven't actually tested?

5. Set Your Top Cybersecurity Priorities for 2027

Finally, resist the temptation to simply roll your 2026 cybersecurity project list into 2027.

Instead, identify the three to five initiatives that would meaningfully reduce your organization's risk.

For each priority, answer five questions:

• What risk are we addressing?

• What does success look like?

• Who owns it?

• When should it be completed?

• What people, technology, and budget will it require?

This creates a much stronger security roadmap than a long wish list of products and projects.

Cybersecurity budgets are limited. Staff time is limited. The goal isn't to do everything. It's to make sure your available resources are focused on the risks that matter most to the business.

Ask yourself: If we could accomplish only three cybersecurity improvements next year, which ones would reduce our risk the most?

Start 2027 with a Plan

A good year-end cybersecurity review shouldn't leave you with a longer checklist. It should leave you with greater clarity.

Going into 2027, you should know:

What you must do.
What risks you have.
What you're accepting.
What you're fixing.
And what's most important next.

Start 2027 knowing which cybersecurity risks matter most and what to do about them. If you can’t confidently answer the questions above, schedule a call with our team to discuss your priorities and whether an independent cybersecurity risk assessment is the right next step. The goal isn’t another report for the shelf. It’s a prioritized, actionable plan to help you
