CyberRidge provides photonic layer security (PLS) for protecting data in transit against quantum computing threats and Harvest-Now-Decrypt-Later attacks. The solution operates at the optical layer to make data unrecordable by spreading signals over a large optical spectrum and burying them below optical noise. The Carmel product delivers 100G+ optical transmission speeds with zero latency and no link length limitations. It substitutes transmission line cards in existing infrastructure and uses constantly changing optical keys that are distributed within the signal itself in an air-gapped environment. The system modifies optical features using optical keys while keeping metadata unexposed. CyberRidge's approach prevents data recording at the physical layer rather than relying solely on encryption algorithms. The technology is designed to be immune to all computing power, including quantum computers, by making the raw data unharvestable. The solution integrates into legacy networks without imposing transmission distance limitations or susceptibility to amplification issues. The product is positioned as Post Quantum Ready (PQR) and can be deployed in weeks with a plug-and-play approach. It operates as an energy-efficient solution that replaces existing transmission line cards in optical infrastructure. The company has received $26M in total funding and has been recognized as a Gartner Cool Vendor in Data Security.
