## Key takeaways

- Regular, tested, offline backups are your most important defence
- Multi-factor authentication stops most credential-based attacks
- Employee phishing training measurably reduces successful attacks
- Patching promptly closes the vulnerabilities attackers most commonly exploit

## Why ransomware remains so effective

Ransomware encrypts an organisation's files and demands payment for the decryption key. It remains devastatingly effective because it exploits human behaviour (clicking phishing links), software vulnerabilities (unpatched systems) and misconfiguration (over-privileged accounts). Paying the ransom does not guarantee recovery — and funds the next attack.

## The practical defences

**Backups first.** Offline, tested, regularly updated backups are the single most important control. If you can restore from backup, ransomware becomes an expensive inconvenience rather than an existential threat. Test restores quarterly.

**Multi-factor authentication.** Most ransomware attacks begin with stolen credentials. MFA on all accounts — especially email and VPN — blocks the vast majority of credential-stuffing and phishing attacks.

**Patch promptly.** Known, unpatched vulnerabilities are the most common initial access point. A patch window of 48 hours for critical issues, 30 days for high severity, closes the most exploited attack surface.

**Phishing training.** Regular simulated phishing exercises measurably improve employee vigilance.

**Segment your network.** Network segmentation limits how far an attacker can move laterally before deploying ransomware.
