Trinity Cyber Full Content Inspection (FCI) is an active network defense platform that provides real-time threat detection and prevention through deep content inspection technology. The platform operates as a centrally managed, global security service that intercepts and analyzes network traffic at line speed without introducing latency or disrupting legitimate communications. The FCI technology uses proprietary detection syntax to identify adversarial behavior, tools, and tactics, techniques, and procedures (TTPs) rather than relying solely on indicator of compromise (IOC) approaches. It performs full content parsing and inspection of network traffic, including decrypted data, to detect threats that traditional security solutions might miss. The platform achieves a false positive rate under 0.01% by analyzing fully parsed content rather than metadata or signatures alone. It provides 72 hours of decrypted, searchable packet capture (PCAP) data through a web portal interface, enabling comprehensive network visibility and forensic analysis capabilities. Trinity Cyber delivers FCI as a fully managed subscription service, where their security operations team continuously refines threat detection countermeasures through content-based threat hunting, threat intelligence research, and malware analysis. The service includes active threat blocking at the network perimeter, reducing alert volumes, log storage costs, and incident response requirements for customers. The platform combines preventive security controls with detection capabilities to stop threats before they can enter or exit the network infrastructure, positioning itself as an active cyber security solution rather than a passive monitoring tool.
