Keep up security hardening
A clean security scan is a snapshot, not a guarantee: headers, cookie flags, and TLS configuration are all things a later deploy, a new third-party script, or an infrastructure change can quietly weaken without anyone noticing, since none of them fail loudly the way a broken build does.
Why it matters
Security posture erodes silently as new code, third-party scripts, or config changes land, so a clean check today does not guarantee a clean check next quarter.
How to fix
- 1 Re-run the security checks after major deploys or vendor/script changes.
- 2 Keep TLS certificates, headers, and dependencies up to date.
Common mistakes
- Treating a passing scan as a one-time certification rather than re-checking after the next major deploy or vendor/script change.
- Adding a new third-party tag (analytics, chat widget, ads) without checking whether it weakens CSP, sets insecure cookies, or otherwise reopens something the last scan closed.
- Letting TLS certificates or security headers live in infrastructure config that nobody owns, so a routine platform migration silently drops one.
How to verify
- 1 Re-run the security checks after any deploy that touches headers, cookies, TLS config, or adds a new third-party script.
- 2 Keep a short checklist of the headers and cookie flags this site depends on, so a config change that drops one is caught by process, not luck.
- 3 Track security header/cookie regressions the same way uptime or error-rate regressions are tracked, not as a one-off audit.
