Remove sensitive data from Cisco configs before posting on Reddit, Cisco Community, or sending to TAC. The sanitizer redacts passwords, SNMP community strings (including trap host communities), TACACS+ and RADIUS keys, crypto ISAKMP pre-shared keys, banner content, and optionally anonymizes IP addresses using RFC 5737 documentation ranges. For configs you cannot send off box, a desktop version runs the same redaction fully offline on your own machine.
