Insecure Cipher Suite Audit

Audits server cipher suites to ensure insecure algorithms (RC4, 3DES, CBC, MD5) are disabled.

Test Your Website for Insecure Cipher Suite Audit

Run this check along with 90+ automated tests across your domain.

Why It Matters

Weak ciphers allow eavesdroppers to decrypt intercepted traffic retroactively using known cryptanalytic exploits.

How We Check This

We test cipher suite negotiation and verify the absence of RC4, 3DES, export ciphers, and NULL ciphers.

How to Fix & Implement

Copy-paste configuration blocks tailored for your web server or edge proxy.

Frequently Asked Questions

What is Forward Secrecy?

Ephemeral Diffie-Hellman keys (PFS) ensure past sessions cannot be decrypted even if the server private key is leaked later.
