Ransomware Protection for Small Businesses

Ransomware doesn't just target big corporations. Small businesses are increasingly the primary target because they often lack dedicated security staff and are more likely to pay. The best defense is preparation — not paying ransom.

How Ransomware Works

Ransomware encrypts your files and demands payment (usually cryptocurrency) for the decryption key. Modern ransomware also steals data before encrypting, threatening to publish it if you don't pay. This "double extortion" makes the threat particularly severe for businesses with sensitive customer data.

The 3-2-1 Backup Rule

Your best protection against ransomware is a solid backup strategy:

• 3 copies of your data
• 2 different storage types (local drive + cloud, for example)
• 1 copy offsite (or in a separate cloud account)

Critical addition: at least one backup must be offline or immutable. If ransomware can reach your backup through your network, it's not a backup — it's another target.

Prevention Measures

• Employee training — 90% of ransomware arrives via phishing emails. Train your team to spot suspicious messages.
• Email filtering — block known malicious senders and suspicious attachments before they reach inboxes.
• Software updates — patch vulnerabilities promptly. Many ransomware attacks exploit known, patched vulnerabilities.
• Endpoint protection — modern antivirus/EDR tools detect and block ransomware behavior patterns.
• Network segmentation — limit how far ransomware can spread if one device is compromised.
• Least privilege access — users should only have access to what they need for their job.

If You're Hit

• Disconnect immediately — isolate infected devices from the network to prevent spread.
• Don't pay — payment doesn't guarantee decryption and funds criminal operations. Only 65% of companies that pay actually recover their data.
• Report it — file with the FBI's IC3 and your local law enforcement.
• Restore from backup — if your backups are clean and recent, you can recover without paying.
• Investigate the entry point — find how they got in and close that door before restoring.
