Our email got hacked despite security in place – 3 mistakes every business should avoid

Even strong filters aren’t enough without layered security

Even with filters, breaches happen without MFA, internal scanning, and staff training.

Real-world example – when one weak link is all it takes

One client I worked with had a strong email filtering system — but no multi-factor authentication (MFA) for executives. A hacker guessed a password, logged into the CEO’s account, and sent fake invoices to suppliers. Since the messages came from inside the organization, the filters didn’t see them as threats.

Three critical mistakes that lead to breaches

This kind of breach usually boils down to three avoidable mistakes:

Mistake 1 – Not enabling MFA for everyone, especially executives

Mistake 2 – Not scanning internal messages for suspicious content

Mistake 3 – Not providing regular security awareness training

Prevention is possible — but only if done early

The fix isn’t complicated — but it has to be done before the breach happens. If your email security only looks outward, you’re leaving a big door open.
