Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally
before we release them, and we strive to correct all vulnerabilities quickly. If you
think that you have identified a vulnerability in a Cisco product, contact PSIRT:
• For emergencies only — [e-mail]
An emergency is either a condition in which a system is under active attack
or a condition for which a severe and urgent security vulnerability should be
reported. All other conditions are considered nonemergencies.
• For nonemergencies — [e-mail]
In an emergency, you can also reach PSIRT by telephone:
• 1 877 228-7302
• 1 408 525-6532
Tip 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
