← All sixteen checks Enhanced TLS Configuration

Enhanced TLS
explained.

Overview

What is Enhanced
TLS?

TLS (Transport Layer Security) configuration checks verify that your server uses secure TLS versions, proper cipher suites, and secure settings.

Importance

Why it
matters.

Proper TLS configuration prevents attacks like BEAST, POODLE, and other TLS vulnerabilities. Weak ciphers, TLS compression, or insecure renegotiation can allow attackers to decrypt or intercept communications. This is critical for protecting sensitive business and customer data.

Risks

What can
go wrong.

Weak TLS configuration: allows attackers to decrypt communications, enables man-in-the-middle attacks, exposes sensitive data, and fails security compliance. TLS compression (CRIME attack) and client-initiated renegotiation are serious vulnerabilities.

Under the hood

Technical
details.

TLS checks verify: 1) TLS version 1.2 or higher (TLS 1.3 preferred), 2) Strong cipher suites with proper ordering, 3) Secure key exchange parameters, 4) No TLS compression (vulnerable to CRIME), 5) Secure renegotiation enabled, 6) Client-initiated renegotiation disabled, 7) 0-RTT (early data) status.
