Modern security now works where the internet doesn’t

A Cylake rack unit — a two-rack-unit appliance with a perforated teal faceplate.

Cylake is the complete, AI-native cybersecurity platform that provides full visibility, sets fine-grained policy, and stops attacks in fully air-gapped sovereign environments.

All these years of “cloud-first”.
What happened to you-first?

Cloud-first worked for everyone who could follow it there. The most critical networks couldn’t. They got throttled data, stripped-down versions, compliance nightmares, and roadmaps that never included them.

We are rebuilding the entire cybersecurity stack all over again and start the other way: your requirements, your premises, your data going nowhere.

Cylake is built for you.

A supercomputer that is optimized for cyber, provides visibility, sets policy, stops attacks, lives on premises, won’t fail.

That just happens to
fit in your rack

Cylake ships appliances. Rack them, power them, done. Need more capacity? Add another unit. It scales by stacking, runs itself like a private cloud deployment, and doesn’t phone home. Nothing leaves the building unless you carry it out.

Go ahead. Hug it.

Nobody else would dare rebuild security from the metal up. Nobody else could.
