AI Cyber Security for UK Small Businesses (2026)
AI has democratised cyber security. Enterprise-grade threat detection, phishing prevention, and vulnerability scanning — all previously costing thousands per year — are now built into tools small businesses already use. Microsoft Defender (free with 365), AI-powered email filtering, and automated patch management handle 95% of small business security needs. The managed security packages charging £600/month are selling fear, not protection.
Penny 的觀點
AI security for under £500/year covers 95% of small business risk: Microsoft Defender with AI threat detection (free with 365), AI-powered email filtering (free with 365), password manager with AI breach alerts (£3/user/month), automated cloud backups (£10/month), and an AI-generated staff awareness module (£200 one-off). Total: under £500/year. The £600/month managed security packages are selling you protection that's already built into your existing tools.
來自我的筆記
“An interior design firm with 6 staff was paying £600/month for "managed security" from their IT provider. I asked what it included: antivirus (Microsoft includes this free), email filtering (Microsoft 365 includes this), and monthly vulnerability scans. We cancelled the package, enabled Microsoft's built-in AI security features, added a password manager with AI breach monitoring, and set up automated backups. Monthly cost: £18. AI handles the security, the budget handles itself. Saved £6,984/year.”
“83% of UK small business cyber breaches are caused by phishing emails and weak passwords — not sophisticated attacks.”
