Enterprise-Grade Website Security Implementation
About this Project
Built and deployed a comprehensive web security system that transformed the site from basic security to enterprise-grade protection with A+ ratings across all major security testing platforms.
A+ on every scanner
Mozilla Observatory scores it 110 out of 100, with matching A+ grades from SSL Labs and Security Headers.
Strict content security
Every script is allow-listed by its hash, so nothing runs in the browser that I have not explicitly approved.
HTTPS with no exceptions
Two-year HSTS with preload keeps every visit encrypted, even the very first one.
Monitored, not forgotten
Automated checks watch the headers and dependencies, so a regression shows up before an attacker does.
Locking a site down without breaking it is a balancing act. A strict policy blocks the inline scripts that analytics and animation libraries rely on, so each one had to be hashed, replaced, or dropped until the whole site ran clean under the tightest settings.
The site now sits in the top tier of independently tested websites, and the same hardening checklist is applied to every project I ship.
