Why Security Headers Matter
Stop Malicious Scripts
Hackers love injecting scripts into websites. A proper Content Security Policy tells browsers exactly what's allowed to run — and blocks everything else.
Always Encrypted
Without HSTS, someone on the same Wi-Fi can intercept your visitors' data. One header makes sure every connection is secure — every single time.
