How Often Should Businesses Review Their Cybersecurity?

19 June 2026

Cybersecurity is not something you can set up once and forget about. Threats change, technology evolves, and businesses regularly add new systems, software, and employees. What was secure six months ago may not be secure today.

Regular cybersecurity reviews help businesses identify weaknesses before they become serious problems. They also ensure that security measures continue to support the way the business operates.

Why Regular Reviews Matter

Cybercriminals are constantly developing new techniques to gain access to business systems and data. At the same time, businesses are introducing new devices, cloud services, and applications that can create additional security risks.

Without regular reviews, organisations can end up with:

• Former employees still having access to systems
• Outdated software with known vulnerabilities
• Weak passwords and poor security practices
• Unused accounts that could be exploited
• Security policies that no longer reflect current working practices

A scheduled review process helps keep these risks under control.

How Often Should Cybersecurity Be Reviewed?

Different areas of cybersecurity should be reviewed at different intervals.

Continuous Monitoring

Security monitoring should ideally be ongoing. This includes:

• Monitoring suspicious login attempts
• Reviewing security alerts
• Tracking unusual network activity
• Watching for malware or ransomware threats

The earlier a problem is detected, the easier it is to contain.

Monthly Reviews

Each month, businesses should:

• Check that critical software updates have been applied
• Review backup success reports
• Confirm antivirus and endpoint protection systems are functioning correctly
• Look for unusual user activity

These simple checks can prevent small issues from becoming major incidents.

Quarterly Reviews

Every three months, businesses should review:

• User access permissions
• Shared accounts
• Privileged administrator accounts
• New devices added to the network
• Third-party supplier access

People's roles change regularly, and access rights should change with them.

Annual Cybersecurity Audits

At least once a year, businesses should carry out a more comprehensive cybersecurity review.

This may include:

• Security policy reviews
• Risk assessments
• Vulnerability scanning
• Disaster recovery testing
• Backup recovery testing
• Staff cybersecurity awareness assessments

An annual audit provides a clear picture of the organisation's overall security posture and highlights areas for improvement.

Don't Forget Employee Training

Technology is only part of cybersecurity. Employees remain one of the most common targets for phishing attacks and social engineering scams.

Regular staff training should be reviewed and refreshed throughout the year. Many organisations benefit from annual training programmes supported by periodic reminders and phishing simulations.

Signs It's Time for an Immediate Review

Even if your next scheduled review is months away, certain events should trigger an immediate cybersecurity assessment:

• A cyber attack or security incident
• Major software or infrastructure changes
• Office relocations
• Business acquisitions or mergers
• Significant staff turnover
• Introduction of remote or hybrid working arrangements

These changes can introduce new risks that need to be addressed quickly.

How Maple Can Help

Keeping on top of cybersecurity reviews can be challenging, especially for busy businesses without dedicated IT security teams. At Maple, we help organisations stay protected through proactive monitoring, security assessments, access reviews, patch management, backup testing, and ongoing cybersecurity guidance. Regular reviews help identify vulnerabilities early and reduce the risk of costly downtime or data breaches.

Cybersecurity is an ongoing process, not a one-time project. Regular reviews ensure your business remains secure, compliant, and prepared for emerging threats.
