CyberRidge, founded in 2022 by Professor Dan Sadot of Ben-Gurion University, secures data in transit at the photonic layer rather than relying solely on traditional cryptography. Its plug-and-play system spreads data across a broad optical spectrum, modifies it with continuously changing optical keys distributed within the signal itself, and buries it beneath optical noise so it cannot be recorded, tapped or post-processed. The approach defeats 'harvest-now-decrypt-later' attacks and is resistant to quantum analysis, with zero added latency and no distance limitation, deployable by substituting existing transmission line cards on standard fiber infrastructure. Gartner named CyberRidge a 2025 'Cool Vendor in Data Security.' The company employs around 20 people in Israel plus US teams, and works with partners including Menhir Photonics and the Singapore-Israel Industrial R&D Programme. CyberRidge emerged from stealth in October 2025 with $26M total funding, including a $16M Series A (Arkin, Redseed VC, Elron Ventures and an EIC grant) following a $10M seed led by Awz.
