Most small businesses don't need a security operations center. They need five things done right and proof they did them. That's the entire premise behind Cyber Essentials, the UK government-backed certification scheme run through the IASME Consortium on behalf of the NCSC. It's cheap, it's self-assessed at the base level, and it maps directly to the attacks that actually hit small organizations: phishing, credential theft, unpatched software, and misconfigured firewalls.

The five controls, no fluff

Cyber Essentials checks exactly five technical areas, and the questionnaire is built around them.

• Firewalls and routers — boundary devices must have default passwords changed and unnecessary services closed off.
• Secure configuration — no default admin accounts left active, no unused software sitting on machines, and auto-run features disabled where they'd let malware execute without a click.
• User access control — accounts should follow least privilege, admin rights are separate from day-to-day accounts, and there's a process for removing access when someone leaves.

• Security update management — patches for high or critical vulnerabilities need to go on within 14 days of release, across operating systems, browsers, and any installed applications the business uses.

That 14-day patching window is the one that trips people up most. It's not
