As the year winds down, many business owners shift focus to financial reports, staffing, and next year’s goals. But one critical area often gets overlooked during year-end planning — cybersecurity. 

For small and midsize businesses (SMBs), the threat landscape is constantly evolving. Hackers no longer target only large enterprises; they increasingly go after smaller organizations with limited IT resources. A single data breach can lead to costly downtime, reputational damage, and regulatory issues — all of which can be devastating for a growing business. 

That’s why year-end is the perfect time to review, strengthen, and future-proof your cybersecurity strategy. Use this checklist to make sure your organization heads into the new year secure and resilient. 

1. Review Access Controls and User Permissions 

Over time, employees change roles, leave the company, or gain access they no longer need. Unchecked permissions create unnecessary risk. 
Perform an access audit to: 

• Remove inactive users or old accounts. 
• Ensure each employee only has the access necessary for their role (principle of least privilege). 
• Implement multi-factor authentication (MFA) for all critical systems. 

A clean access list ensures that only the right people have the right access — and no one else. 

2. Assess Endpoint Security 

Your devices — laptops, desktops, and mobile phones — are often the first line of defense. Confirm that all endpoints: 

• Run up-to-date antivirus and anti-malware software. 
• Receive regular OS and application updates. 
• Are encrypted, especially if employees work remotely or use personal devices. 

Even one unprotected device can become an open door for attackers. 

3. Test Your Backup and Disaster Recovery Plan 

A strong backup and disaster recovery (DR) strategy ensures you can recover data quickly after a cyberattack or outage. But having a plan isn’t enough — you need to test it. 
At year-end, verify that: 

• Backups are running on schedule and data restoration has been tested. 
• Backup copies are stored securely offsite or in the cloud. 
• You can recover critical systems within your target recovery time objectives (RTOs). 

This step not only protects your data but also gives peace of mind heading into the new year. 

4. Evaluate Employee Awareness and Training 

Human error remains one of the leading causes of data breaches. A single phishing email can compromise your entire network. 
Consider launching a year-end security refresher training to educate employees about: 

• Recognizing phishing attempts. 
• Handling sensitive data securely. 
• Reporting suspicious activity promptly. 

Investing in cybersecurity awareness is one of the most cost-effective defenses an SMB can have. 

5. Review Your Vendor and Partner Security 

Your security is only as strong as the weakest link in your supply chain. Vendors and third-party partners often have access to your systems or data — making them potential entry points for attackers. 
As part of your year-end review: 

• Confirm that vendors meet your security standards. 
• Revisit data-sharing agreements and access levels. 
• Ask partners about their own cybersecurity and data protection policies. 

6. Update Policies and Incident Response Plans 

Policies written years ago may no longer fit today’s digital environment. Review your cybersecurity and incident response plans to ensure they reflect current technologies, regulations, and threats. 
Ask yourself: 

• Do we have a clear response procedure for a cyber incident? 
• Are key contacts and roles updated? 
• How quickly can we detect, contain, and communicate a breach? 

An up-to-date plan ensures your team knows exactly what to do if an incident occurs. 

7. Plan Ahead for 2026 

Once your immediate checklist is complete, look ahead. 

• Budget for security upgrades, audits, or managed security services. 
• Consider partnering with a vCISO or managed security provider to strengthen your defenses. 
• Schedule quarterly reviews so cybersecurity remains a year-round priority. 

Cyber threats won’t slow down — but with the right strategy, neither will your business. 

Final Thoughts 

Cybersecurity isn’t a once-a-year task — it’s an ongoing commitment. But conducting a thorough year-end review helps you identify gaps, reinforce defenses, and start the new year with confidence. 

The reality is simple: prevention is far less costly than recovery. 
As you prepare your business for growth in 2026, make cybersecurity a top item on your checklist — because a secure business is a sustainable business.
