Novel tools and techniques are provided for implementing fraud or distributed denial of service ('DDoS') protection for session initiation protocol (“SIP”)-based communication. In various embodiments, a computing system may receive, from a first router, first SIP data indicating a request to initiate a SIP-based media communication session between a calling party at a source address and a called party at a destination address. The computing system may analyze the received first SIP data to determine whether the received first SIP data comprises any abnormalities indicative of potential fraudulent or malicious actions. If so, the computing system may reroute the first SIP data to a security deep packet inspection (“DPI”) engine, which may perform a deep scan of the received first SIP data to identify any known fraudulent or malicious attack vectors contained within the received first SIP data. If so, the security DPI engine may initiate mitigation actions.
