Phishing Prevention Strategies
Practical steps organizations can take to reduce phishing risk and protect employees and customers.
Defense in Depth
No single measure stops all phishing. Effective defense requires multiple layers: technical controls, human awareness, and rapid response capabilities.
Technical Controls
Email Security
- SPF, DKIM, DMARC – Authenticate your domain to prevent spoofing
- Email filtering – Block known phishing indicators
- Link scanning – Check URLs in emails against threat databases
- Attachment sandboxing – Analyze files before delivery
Web Security
- DNS filtering – Block access to known phishing domains
- Browser isolation – Contain risks from suspicious links
- Certificate checking – Warn on suspicious certificates
Authentication
- MFA everywhere – Reduce credential theft impact
- Password managers – Auto-fill only on correct domains
- Passwordless options – FIDO2/WebAuthn resist phishing
Employee Training
- Regular security awareness training
- Phishing simulations to test and reinforce
- Clear reporting procedures for suspected phishing
- No punishment for reporting—encourage vigilance

- Monitor for phishing sites targeting your brand
- Track domain registrations containing your brand
