The Business Website Security Checklist for 2026

A hacked small-business site costs an average $25k in recovery, downtime, and reputation damage — yet 90% of breaches exploit basics nobody checked. Run this 20-minute audit on your site today.

Infrastructure (mostly platform-level)

  • ✅ SSL certificate active AND auto-renewing
  • ✅ HTTPS everywhere — no mixed-content warnings
  • ✅ Security headers set (X-Content-Type-Options, X-Frame-Options)
  • ✅ Daily automated backups — and you've tested a restore this quarter
  • ✅ Server-side malware scanning running on schedule

Application (your responsibility)

  • ✅ CMS, plugins, themes updated — every unpatched version is a known-exploit list
  • ✅ Admin URL changed from defaults; strong unique passwords everywhere
  • ✅ File upload forms restrict type and size server-side
  • ✅ Error pages don't leak stack traces or file paths
  • ✅ Unused plugins/themes/accounts deleted, not just disabled

Access and process

  • ✅ Team members have individual logins, not shared admin credentials
  • ✅ Former employees/contractors' access revoked
  • ✅ Someone reviews access logs or audit trail monthly

The uncomfortable truth

Most checklists fail at maintenance, not setup. That's the case for platforms that automate the infrastructure half — when SSL, headers, backups, and scanning run themselves, you only have to mind the application column.
