An Israeli startup that has developed technology to stop data being stolen from internet cables has emerged from stealth with a total of $26 million in funding.
CyberRidge states its technology manipulates light to conceal data as it travels through fiber-optic cables on the seabed or on land.
If an adversary — like a nation state — cuts the cables and tries to steal the data, they would only capture “random noise,” Dan Sadot, the CEO and founder of CyberRidge, notified Business Insider.
“We are transmitting the data in a way that is unobservable,” added Sadot, a professor at Ben-Gurion University with nearly 30 years of experience in optical communication.
Subsea cables, which are typically about as thick as a garden hose, are the backbone of the internet and crucial to the world’s economy.
Data is already encrypted as it travels through sprawling fiber-optic cables around the world. However, it can be siphoned off and stored with the intention of decrypting it in the future with powerful quantum computers, which are expected to crack today’s encryption standards. CyberRidge’s technology is “complementary” to existing protections rather than competing with them, Sadot declared.
The startup’s core product is a hardware box that sits at the conclude of each fiber cable. Customers can recompose the data at each conclude with a “photonic key” that “alters every fraction of a second,” Sadot declared.
Sadot notified Business Insider that he founded the company about three and a half years ago after an Israeli innotifyigence unit encouraged the commercialization of the concept.
CyberRidge’s potential customers include telecommunications companies, hyperscale cloud companies such as Amazon Web Services, and large banks, among others.
The startup has a flexible business model that includes the direct purchase, leasing, and subscription-as-a-service of its hardware, Sadot added.
Most of the funding comes from a $10 million seed investment led by Awz Ventures, followed by an additional $15 million extension from Arkin Capital, Redseed VC, and Elron Ventures.
The startup plans to apply the capital to relocate from prototype to full production of its hardware by the conclude of March 2026, Sadot declared.
