A computer program product for throttling traffic from a source internet protocol address, the computer program product comprising:

• a computer usable medium having computer usable program code embodied therewith, the computer program product comprising:
• computer usable program code configured to inspect payloads of a plurality of packets, each packet having a source address identical to the source internet protocol address and a target address corresponding to a receiver host;
• computer usable program code configured to forward packets having the source address, responsive to detecting purported good content within at least one of the plurality of packets;
• computer usable program code configured to determine whether a count of packets having the source address exceeds a safe threshold;
• computer usable program code configured to request a demanded positive trust report from the receiver host, responsive to a determination that the count of packets having the source address exceeds the safe threshold;
• computer usable program code configured to determine whether a positive trust report is received from the receiver host that indicates that the source internet protocol address is good;
• and
• computer usable program code configured to analyze a header of packet having the source address without analyzing a payload of the packet, responsive to a determination that the positive trust report is received from the receiver host.
