Common Cyber Insurance Mistakes That Increase Premiums

Your Cyber Insurance Premium Is Trying to Tell You Something

When cyber insurance premiums go up at renewal time, most business owners chalk it up to market conditions and move on. And while it is true that the cyber insurance market has gotten significantly more expensive across the board, the reality is that a meaningful portion of the premium increases businesses are experiencing come down to specific, preventable mistakes that make insurers view them as higher risk.

This matters because the gap between what a well-protected business pays for cyber insurance and what a poorly protected business pays is growing. Insurers are getting much better at assessing real security posture, and the businesses that cannot demonstrate strong controls are paying for it in their premiums. In some cases significantly.

The good news is that the mistakes driving those higher premiums are almost all fixable. And fixing them does not just reduce your insurance costs. It actually makes your business more secure, which means a lower likelihood of ever having to file a claim in the first place.

This post is going to walk through the most common cyber insurance mistakes that are driving up premiums for small and mid-sized businesses right now, and what you can do about each of them.

Mistake 1: Not Having Multi-Factor Authentication in Place

This is the single most common issue that cyber insurance underwriters flag during the application and renewal process, and it is one that continues to catch businesses off guard even in 2025.

Multi-factor authentication, which requires users to verify their identity with a second factor beyond their password before accessing critical systems, is now considered a baseline security requirement by virtually every major cyber insurer. Businesses that cannot confirm multi-factor authentication is enabled on email, remote access tools, financial systems, and other critical applications are viewed as significantly higher risk and are priced accordingly.

The frustrating part is that multi-factor authentication is one of the most effective and least expensive security controls available. It stops the vast majority of unauthorized access attempts even when passwords have been stolen or guessed. There is almost no justification for not having it in place across your critical systems, and from an insurance perspective, not having it is one of the fastest ways to push your premium up.

A good managed IT service provider implements and manages multi-factor authentication across your environment as a standard part of their service, ensuring this fundamental control is consistently in place and properly configured.

Mistake 2: Having Backups That Have Never Been Tested

Most businesses have some form of data backup in place. Far fewer have backups that have been properly tested to confirm they actually work. And this distinction matters enormously to cyber insurers.

Insurers are not just looking for evidence that a backup system exists. They want evidence that backups are being tested regularly, that the results are documented, and that the business could actually restore its systems and data within a reasonable timeframe if something went wrong. A backup solution that was set up years ago and has been running quietly in the background without anyone verifying its integrity does not satisfy this requirement.

For businesses that have never tested their backups, the stakes go beyond insurance premiums. A ransomware attack is the moment of truth for any backup solution, and discovering that your backups have not been running correctly is one of the worst possible times to find that out. Proper data backup and recovery solutions include regular testing, monitoring, and documentation as a core part of the service, not an afterthought.

Mistake 3: No Documented Employee Cybersecurity Training Program

Cyber insurers are asking increasingly specific questions about employee security training, and vague answers are being treated as red flags. It is not enough to say that your team is generally aware of cybersecurity best practices. Insurers want to know that you have a documented, ongoing training program that covers specific topics like phishing recognition, password hygiene, and proper data handling.

This requirement has become more important as AI-powered phishing attacks have made human error a more significant factor in successful cyberattacks. Insurers understand that even the best technical controls cannot fully compensate for an untrained workforce, and they price accordingly.

Businesses that cannot document their employee training program face higher premiums and are also genuinely more vulnerable to the attacks that training is designed to prevent. A comprehensive cybersecurity services program includes employee training as a core component, complete with documentation that satisfies insurer requirements.

Mistake 4: Using Outdated or Unsupported Software

Running software that is no longer supported by its vendor is a significant red flag for cyber insurers and for good reason. When software reaches end of life, the vendor stops releasing security patches for newly discovered vulnerabilities. This means that any vulnerability found after that date remains permanently exploitable in your environment.

Insurers are aware that outdated software is one of the most commonly exploited attack vectors for ransomware and other malware. Businesses that are running end-of-life operating systems or applications are carrying a level of risk that insurers are increasingly unwilling to absorb at standard rates.

Staying current on software updates and proactively planning for the replacement of end-of-life systems is a core part of what good managed IT services deliver. When someone is consistently managing your patch levels and flagging systems that are approaching end of life, you avoid the situation where outdated software becomes both a security liability and an insurance premium driver.

Mistake 5: No Formal Incident Response Plan

When a cyberattack occurs, the speed and effectiveness of your response makes an enormous difference in the scope of the damage. Businesses that have a documented incident response plan in place before something happens contain attacks faster, recover more quickly, and experience less overall damage than businesses that are figuring out what to do in real time.

Cyber insurers understand this and are increasingly asking whether businesses have a formal incident response plan as part of the underwriting process. Businesses without one are viewed as higher risk not just because they are more likely to suffer greater losses from an incident but also because they are more likely to make decisions in the heat of the moment that complicate the insurer's ability to manage the claim.

A documented incident response plan does not have to be complex but it does need to exist and the right people need to know where it is and what to do when something goes wrong. This is another area where working with a knowledgeable IT support partner helps significantly. A good managed IT service provider helps you build and document an incident response plan and makes sure it is integrated into how your team responds when technology issues arise.

Mistake 6: Giving Employees More Access Than They Need

Privileged access management, meaning the practice of ensuring employees only have access to the systems and data they actually need to do their jobs, is increasingly scrutinized by cyber insurers. The logic is straightforward. The fewer systems and data sets an employee account has access to, the less damage a compromised account can cause.

Businesses where employees have broad access to systems and data beyond what their role requires are carrying more risk than they need to. A compromised account with access to everything is a much more serious incident than a compromised account with limited access. Insurers price this risk accordingly.

Regular access reviews that confirm employees have appropriate permissions for their current roles, and that access is promptly revoked when employees change roles or leave the company, are a fundamental part of a sound security posture. This is something a managed IT service provider manages as part of ongoing IT operations, ensuring access levels stay appropriate over time rather than accumulating unchecked.

Mistake 7: Not Being Able to Document Your Security Controls

This is perhaps the most underappreciated mistake on this list. A business might actually have most of the right security controls in place but still face higher premiums or coverage challenges because they cannot document and demonstrate those controls to their insurer.

Cyber insurance underwriting is increasingly a documentation exercise as much as a security assessment. Insurers want written evidence. Policies. Procedures. Audit logs. Testing records. Training completion records. Patch management documentation. Without this documentation, the controls you have in place might as well not exist from an insurance perspective.

Working with a managed IT service provider who maintains thorough documentation of your security environment as a matter of standard practice gives you exactly what insurers are looking for. When renewal time comes, you are not scrambling to pull together evidence of controls you hope are in place. You have a partner who can produce the documentation that supports your application and demonstrates your security posture clearly and credibly.
