The Honest Story
Where each defense lives. Layer 1-2 filter lives in the SFP module. Layer 3-7 software lives in the router. Different layers, complementary protection.
Why L3-7 software cannot catch timing attacks
Any software running on the router host references the router OS clock. Microsecond resolution at best. Covert timing channels operate at sub-microsecond precision. The signal is below the software clock resolution.
Why L3-7 fails after router kernel compromise
Privileged malware on the router disables IPS, patches out EDR, manipulates the router clock. L3-7 software on that router is compromised. Reachable intranet devices enter the blast radius. The L1-L2 filter is in the SFP module, not on the router. Router kernel compromise cannot reach it.
Why AI-driven attacks make our case stronger
AI can mimic content. AI cannot change the physical timing fingerprint of the hardware producing it. The L1-L2 filter sees the residual.
Two product paths
Inline mode: filter in data path. +25 ns latency. Catches every attack frame.
Passive tap mode: filter watches in parallel. 0 ns added. For trading floors and HFT.
