Most breaches still start the same way they always have: with a person, not a movie style hacker. In 2026 the twist is that AI makes fake messages cleaner, faster and harder to spot. The defence, thankfully, is still mostly common sense done consistently.
The threats to plan for
- AI assisted phishing. Flawless grammar, your branding, and a sense of urgency. Verify unusual requests on a second channel.
- Account takeover. One reused password can unlock your whole business. Unique passwords and multi factor authentication shut this down.
- Invoice fraud. A convincing "updated bank details" email. Always confirm payment changes by phone.
- Ransomware. Good, tested backups turn a disaster into an inconvenience.
Protect your email first
Email is still the front door. Three DNS records do most of the heavy lifting:
- SPF lists who is allowed to send for your domain.
- DKIM cryptographically signs your messages.
- DMARC tells the world what to do with mail that fails the first two.
Without DMARC, anyone can send email that looks like it came from your domain. With it, they cannot.
A 20 minute checklist
- Publish SPF, DKIM and DMARC records
- Turn on multi factor authentication everywhere
- Roll out a password manager
- Send one short awareness note to your team
- Confirm your backups actually restore
