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

We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to 
encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been 
encrypted with PGP versions 2.x through 9.x. 

Never use a revoked encryption key or an expired encryption key. The correct public key to use in your 
correspondence with PSIRT is the one linked in the Contact Summary section of the Security 
Vulnerability Policy page at this URL:

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT to find other means of encrypting the data before sending 
any sensitive material.
