Rebuilding cybersecurity from the metal up.

[Cylake @CylakeAI]

Some engineers think outside the box. Ours sign the inside.

We're building cybersecurity from the metal up, and we're looking for people who want their fingerprints on something entirely new. From applied AI and software infrastructure to endpoint engineering and product design, there's plenty of room to make your mark.

Think you're up for it? We're hiring.

We were just named the Number 1 Security startup on @theinformation 50! 🏆

“YEAH, BABY! — Austin Powers” — @nirzuk 🕺🔥

Most cybersecurity companies build software. We’re building the whole thing. The visibility, policy, and detection engine, the data lake, the AI, and the hardware it all runs on, designed for the environments where security matters most.

We're looking for engineers who want to help shape the architecture, ship technology you can actually touch, and work alongside people who have helped define the cybersecurity industry.

Thank you to The Information for the recognition!

@GreylockVC Thank you for all your support!

A new security challenge can signal an opportunity to build something better.

As organizations entrust AI agents with sensitive information and business decisions, @chandna sees an opening for new architectures that help protect their data and context, their crown jewels.

You don't need to have all the right answers. But you should have some good questions.

We asked Maggie, Cylake's senior recruiter, what advice she'd give someone interviewing with us. Her take? Do your homework. Get curious about what we're building. And don't show up pretending to be someone you're not.

We're rebuilding cybersecurity from the metal up, and we're looking for people who bring their own ideas to the table.

Think you'd fit right in? Come find out.

There's nothing like that new appliance smell. 😎
We're building hardware you can actually touch, giving organizations complete control over their cybersecurity infrastructure and data. Nick Campagna and Jesse Ralston explain why we're bringing cybersecurity back to the metal.

Started from the metal, now we're here. 😎

From rebuilding cybersecurity at the hardware level to seeing Cylake light up the @NYSE trading floor. Not a bad week.

Proud to be recognized on this year's @FortuneMagazine Cyber 60, in partnership with @lightspeedvp and @AWSstartups.

Big ideas take bold people. Lucky for us, we've got a whole team of them. This one's for the builders.

[Cylake @CylakeAI]

Cybersecurity has a data puddle problem, and adding more AI to the puddles isn't going to fix it.

For decades, we've added new security products to solve new problems, each collecting its own data and seeing only part of the picture. Now we're expecting AI to connect the dots across systems that were never designed to work together.

In our latest Substack, our Founder and CEO @nirzuk breaks down how we got here, why fragmented security architectures aren't built for AI, and what needs to change.

Cylake has been named to the @FortuneMagazine Cyber 60™ 2026–2027 list, developed with @lightspeedvp and @AWSstartups, recognizing 60 venture-backed cybersecurity companies shaping the industry's future.

Our team has spent decades building some of the world's biggest security companies. We've seen firsthand what happens when cybersecurity evolves by adding another product, another layer, another disconnected source of data.

So we're taking a different approach. We're rebuilding cybersecurity from the metal up, bringing hardware, software, data, and AI together on a single foundation for organizations where the stakes are highest and partial visibility isn't an option.

This recognition is an exciting milestone for our growing team of engineers, designers, and builders who are challenging long-held assumptions about how cybersecurity should work.

Agents Gone Wild. Coming soon to an enterprise near you. 🤖

As organizations increasingly put AI agents to work, they're also introducing new challenges around governance and security.

In Episode 6 of Inside Cybersecurity, @chandna of @GreylockVC joins @renebonvanie to discuss the evolving cybersecurity landscape, the opportunities emerging with AI, and what he looks for when investing in the next generation of cybersecurity founders.

AI has changed the economics of cyberattacks.

Attacks are cheaper to launch and faster to scale, and human intervention alone can’t keep up.
@MarkatPANW and @renebonvanie discuss why we need algorithms fighting algorithms.

[Cylake @CylakeAI]

To reliably protect an organization, every cybersecurity function needs visibility into the complete picture. That means access to data across endpoint, browser, cloud, SaaS, network, identity, and everything else security teams are responsible for protecting.

That requirement changes where the cybersecurity architecture needs to live: close to the data, on infrastructure the organization controls. @nirzuk breaks down the thinking with @JoelFishbeinJr in Inside Cybersecurity.

Watch the full conversation: https://t.co/TqiZq8b1Ak

[Cylake @CylakeAI]

Cybersecurity has always been asymmetric: attackers only need to find one opening, while defenders have to protect everything that matters. Now, AI is changing the scale and speed of that equation.

@chandna, Partner at @GreylockVC and Cylake board member, believes we're entering an era of machines fighting machines, where increasingly sophisticated attacks powered by “bad AI” will require equally capable “good AI” on defense.

In Episode 6 of Inside Cybersecurity, Asheem joins @renebonvanie to discuss what AI means for the cybersecurity stack, why truly AI-native architectures need to be built differently, and what three decades in cybersecurity have taught him about the people and companies that successfully navigate major technology shifts.

“Do not be afraid to contribute your ideas.” — Alex Fisher, Software Engineer at Cylake

Bring what you’ve learned. Bring the ideas you haven’t had room to build yet.

At Cylake, we work in person, bringing different experiences and perspectives into the same room. We think through hard problems together, speak openly, and take pride in what we build.

We’re rebuilding cybersecurity from the metal up. Hardware, software, data, and applied AI, built as one system. It’s ambitious work, with an experienced team focused on architecture and impact that lasts.

We’re growing. Find your role and help us build: https://t.co/HbVr6RUbrZ
