Trinity Cyber pioneered active network defense - preemptive security that surgically removes threats from live traffic before attackers can establish presence on endpoints and networks. While competing Detection & Response approaches demand alert triage and reactive firefighting, our Full Content Inspection capability meets adversaries in the network and cleans malicious content from protocols, code, and files in real time - with sub-millisecond inspection latency and near-zero false positives. Every day, we work at scale: protecting over 3 million users and processing 1.5 trillion content objects.
