The Ransomware Threat in 2025
Ransomware attacks increased 95% in 2024, with average ransom demands exceeding $1.5 million. Small and medium businesses are increasingly targeted because they often lack robust defenses. Prevention is always cheaper than recovery.
Defense Layers
- Email Security: 90% of ransomware enters via email. Deploy advanced email filtering, sandboxing, and link analysis.
- Endpoint Protection: Next-gen antivirus (CrowdStrike, SentinelOne) with behavioral analysis detects encryption behavior.
- Network Segmentation: Isolate critical systems. If one segment is infected, lateral movement is blocked.
- Access Controls: Enforce MFA, disable RDP externally, and implement privilege access management.
The 3-2-1 Backup Rule
Keep 3 copies of data, on 2 different media types, with 1 copy offsite. Test restore procedures quarterly. Immutable backups (cannot be deleted or encrypted by ransomware) are the gold standard.
Incident Response Plan
Have a documented, rehearsed plan: who to call, how to isolate infected systems, when to involve law enforcement, and how to communicate with stakeholders. Practice with tabletop exercises twice per year.
