The 5 Most Common Security Gaps We Find in Businesses

When we run Microsoft 365 health checks or Dark Web scans for businesses, certain weaknesses appear again and again.

And while every company is different, these common security gaps are easy to overlook — but also easy to fix.

Here are the top five:

1. Weak or Reused Passwords

We still see far too many passwords like “Spring2024!” or even “password123”. These can be cracked in seconds.
Solution: Enforce strong password policies and use a password manager to generate and store unique logins for every account.

2. Multi-Factor Authentication (MFA) Not Enabled Everywhere

Some accounts are protected, others aren’t — leaving holes for attackers to slip through.
Solution: Enable MFA for all accounts, especially admin logins, and consider phishing-resistant methods where possible.

3. Unmonitored Dark Web Exposures

Compromised credentials often sit for sale on the Dark Web long before a breach is noticed.
Solution: Use Dark Web Monitoring to get alerted the moment leaked credentials are found, so you can reset and secure accounts immediately.

4. Outdated or Misconfigured Security Settings in Microsoft 365

Legacy authentication still enabled, overly broad permissions, or unused accounts left active — all create unnecessary risk.
Solution: Regularly review and harden 365 security settings, disable legacy protocols, and remove inactive accounts.

5. No Immutable Backup in Place

Even with security tools, ransomware can still strike — and some attacks target backups too.
Solution: Use immutable backups that can’t be altered or deleted, even by someone with admin access.
