The cybersecurity firm SpiderOak, which is focused on protecting data related to space systems, has received a new round of investments from Accenture [ACN], Raytheon Technologies [RTX], and Stellar Ventures that will accelerate the extension of its marquis product into ground infrastructure.

The value of the investment round wasn’t disclosed. Accenture Ventures, RTX Ventures and Stellar are new investors in SpiderOak, which closed a separate $16.4 million Series C funding round in January.

SpiderOak’s OrbitSecure software product provides zero-trust encryption and distributed ledger to protect data and commands in-orbit and on the ground.

In April, SpiderOak said it entered into a strategic partnership with Raytheon Technologies’ BBN business unit to field new zero-trust systems for satellite communications in proliferated low-Earth orbit (LEO). In March 2022, Lockheed Martin [LMT] and SpiderOak partnered to develop and text a zero-trust cybersecurity platform for the space data supply chain.

“With this new investment, we are even better positioned to continue our growth in the space sector and to provide customers with the highest levels of cybersecurity and resiliency solutions available,” Dave Pearah, CEO of SpiderOak, said in a statement.

Daniel Ateya, head of RTX Ventures, said in a statement that “The satellite systems we rely on to be the eyes and ears of our national defense are very much at risk from cyber threats. We see our investment in SpiderOak as a key enabler in helping our clients maintain secure and resilient data communications and storage in these highly contested environments from ground to LEO to cislunar.”

SpiderOak is based in California. The company has over 10,000 customers using its CrossClave software product that has been adapted for zero-gravity environments. The company has commercial and government customers and soon will make OrbitSecure operational in orbit, it says.
