Essential Layers of Modern Web Security

🔒

Always-On TLS 1.3 Encryption

Modern TLS 1.3 reduces handshake latency and deprecates insecure legacy ciphers (such as RC4 and 3DES), keeping visitor credentials safe from packet sniffing.

🛡️

Strict-Transport-Security (HSTS)

HSTS instructs browsers to strictly communicate over HTTPS, preventing SSL stripping attacks and cookie hijacking on public Wi-Fi networks.

🧱

Content Security Policy (CSP)

A robust CSP restricts the domains from which scripts, styles, and iframes can execute, mitigating Cross-Site Scripting (XSS) and clickjacking attacks.
