There's a persistent myth that ransomware is a large-enterprise problem. The Colonial Pipelines and JBS Foods of the world make headlines, so that's where attention goes. But the data tells a different story: ransomware groups are aggressively targeting small and mid-sized businesses, and the attacks are working.
Why the Shift?
A few dynamics are driving this.
Enterprise defenses have hardened. Large companies have invested heavily in security over the last decade — better detection, incident response teams, cyber insurance that requires controls. Getting through those defenses takes more work than it used to.
Small businesses are comparatively easy. Fewer controls, less visibility, often no dedicated security staff. For a ransomware group, a $50,000 payout from a small manufacturer or medical practice is easier money than trying to crack a Fortune 500.
Ransomware-as-a-Service (RaaS) lowered the bar. Criminal groups now sell ransomware as a subscription. You don't need technical skill to deploy it — just a target and a means of access. The barrier to entry is effectively gone.
What Small Businesses Get Wrong
The most common mistake I see is assuming that size equals safety. "We're too small to be worth targeting." This is exactly backwards. Your size is the reason you're a target.
Second most common: treating ransomware as an IT problem rather than a business risk. Ransomware isn't just about losing data — it's about losing operations, paying ransoms, dealing with regulatory notifications, and rebuilding customer trust. The average cost of a ransomware attack on a small business, including downtime, now exceeds $200,000.
What Actually Reduces Risk
You don't need an enterprise security stack to significantly reduce your ransomware exposure. Focus on the things that matter most:
Email security. The overwhelming majority of ransomware gets in through phishing. A solid email gateway, MFA on all accounts, and trained employees cut off the primary attack vector.
Patching. Ransomware frequently exploits known vulnerabilities that have patches available. A disciplined patching cadence — especially for internet-facing systems and endpoints — closes a massive attack surface.
Backups that actually work. Offline, tested backups are your last line of defense. If ransomware can reach your backups, they won't save you. Backups need to be isolated from your production environment and tested regularly.
Endpoint detection. Modern EDR tools detect ransomware behaviors (mass file encryption, lateral movement) before they can fully execute. This is one area where a modest investment pays significant dividends.
The Bottom Line
Ransomware is a business risk, not just a technical problem. If you're treating it as an IT issue to be solved with the right product, you're missing the bigger picture. Build a defense-in-depth strategy, test your assumptions, and have a plan for when — not if — something gets through.
