Photonic Encryption Startup Exits Stealth with Fiber-Based Security Platform

CyberRidge, a photonic encryption technology and security startup, has emerged from stealth with $26 million in total funding. CyberRidge's flagship product is a plug-and-play photonic layer transmission system that integrates with existing fiber infrastructure and transforms data into encrypted optical noise — making it immune to traditional tapping tools, quantum analysis, or any attempt to capture and postprocess.

According to the company, the only way to recompose the data is with a proprietary photonic key that changes every fraction of a second and must be present at the exact moment the light signal arrives. Without it, the data is lost forever.

The technology is already being deployed across telecommunications providers, defense, and intelligence agencies. Early-stage deployments are underway in Europe, Singapore, and Australia, including a rollout with Israel's military intelligence unit.

CyberRidge's tech offers an alternative to what it calls "software-based solutions" like post-quantum cryptography (PQC) and "physics-intensive approaches" like quantum key distribution (QKD) at a time when the cybersecurity industry, along with governments, military organizations, and critical infrastructure operators are preparing for the “post-quantum” era. CyberRidge's real-time, photonics-based protection is designed to be complementary to PQC and QKD, avoiding dependence on mathematical assumptions and protecting the entire payload data together with the key, according to the company.

Founded by entrepreneur, optical communications expert, and Ben-Gurion University professor Dan Sadot, CyberRidge's team includes 30 employees and partners across Israel, Switzerland, and the U.S. The company was recently awarded a flagship grant from the European Innovation Council (EIC), selected out of more than 1400 companies for its potential to redefine secure communications infrastructure in the EU and beyond.

The current funding includes a $10 million seed investment led by Canadian-Israeli global investment group Awz, followed by an additional $16 million extension from Arkin Capital, Redseed VC, Elron Ventures, and the EU Horizon-EIC program.

Glossary

quantum: The term quantum refers to the fundamental unit or discrete amount of a physical quantity involved in interactions at the atomic and subatomic scales. It originates from quantum theory, a branch of physics that emerged in the early 20th century to explain phenomena observed on very small scales, where classical physics fails to provide accurate explanations. In the context of quantum theory, several key concepts are associated with the term quantum: Quantum mechanics: This is the branch of...
noise: The unwanted and unpredictable fluctuations that distort a received signal and hence tend to obscure the desired message. Noise disturbances, which may be generated in the devices of a communications system or which may enter the system from the outside, limit the range of the system and place requirements on the signal power necessary to ensure good reception.
quantum key distribution: Quantum key distribution (QKD) is a method of secure communication that utilizes principles from quantum mechanics to establish a shared secret key between two parties, typically referred to as Alice and Bob, while detecting any potential eavesdropping attempts by a third party, commonly known as Eve. The fundamental principle behind QKD is the use of quantum properties, such as the superposition principle and the no-cloning theorem, to enable the distribution of cryptographic keys in a...
stealth: That characteristic which makes a weapon system less visible to radar, optical, acousto-optic, infrared and other military sensors.
