5 cybersecurity mistakes small businesses still make in 2026

After conducting hundreds of security assessments across businesses in the past year, our team consistently finds the same five vulnerabilities showing up time and again. The good news: most of these are entirely preventable with the right policies and tools in place.

1. No multi-factor authentication (MFA). This is still the single biggest gap we find. MFA blocks over 99% of credential-based attacks, yet fewer than half of SMBs have deployed it consistently across all their systems. If you implement nothing else from this article, make it MFA.

2. Unpatched software. Patch management is unglamorous IT work, but it matters enormously. The majority of successful ransomware attacks exploit known vulnerabilities that have had patches available for weeks or months. Automated patch management — not quarterly IT reviews — is the standard you should be holding your systems to.

3. No formal phishing awareness training. Human error remains the entry point for over 80% of breaches. Simulated phishing campaigns and regular employee training reduce successful phish rates dramatically, typically from 25–30% to under 5% within a year. This is achievable with tools that cost less than a few hundred dollars per month.

4. Overly permissive access controls. The principle of least privilege — giving employees only the access they need for their role — is often ignored in favour of convenience. Excessive access rights mean a single compromised account can cause catastrophic damage across your systems.

5. No tested backup and recovery plan. Many businesses have backups. Far fewer have tested whether those backups can actually be restored in an acceptable timeframe. Ransomware operators specifically look for and destroy local backups. Offsite, air-gapped, and regularly tested backups are non-negotiable.

If any of these resonate, a proactive security assessment is the fastest way to understand your current exposure and build a prioritized remediation roadmap.
