Cisco is committed to delivering secure products. We test our products internally before we release them,

Emergencies —

Nonemergencies —

We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive 
information that you send to Cisco. PSIRT can work from encrypted information that is compatible with 
PGP versions 2.x through 8.x. 

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence 
with PSIRT is the one that has the most recent creation date in this public key server list:

In an emergency, you can also reach PSIRT by telephone:
