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.

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.

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. Hear more: substack.com/@cylake/note/p-…

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.

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. 🎧 Watch Episode 6 of Inside Cybersecurity: cylake.substack.com/p/good-a…

“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: cylake.com/company/careers/?…

The hardest environments should help shape the security built for them. That’s the idea behind Cylake’s Design Partner Program. Security and technology leaders bring us their constraints, work directly with our team, and help shape the platform before commercial launch. In Episode 5 of Inside Cybersecurity, Head of Product Management Nick Campagna explains how the program works and why we’re building with these partners from the start. Listen here: cylake.substack.com/p/inside…

A 99% attack detection rate used to be good enough. Not because the remaining 1% didn’t matter. Developing enough different attacks to consistently find a way through was expensive, largely limiting that capability to nation states and sophisticated criminal organizations. GenAI changes that equation. When developing and iterating on new attacks becomes dramatically cheaper, attackers can keep looking for the gap until they find it. @nirzuk and @renebonvanie explain why that changes a longstanding assumption in cybersecurity: that keeping adversaries out is enough.

The networks we depend on most are being asked to choose between keeping their data and boundaries intact or sending more data elsewhere to get modern security. That is the wrong choice for critical infrastructure. Power and water providers are among the organizations working with us through Cylake’s Design Partner Program. They’re showing us what security has to look like when systems cannot simply connect outward and sensitive data cannot simply leave. Their requirements are shaping what we build. The intelligence comes to the data, on infrastructure they control. We wrote about what we’re learning and why the architecture has to start with their constraints: cylake.substack.com/p/stop-a…

We’re continuing to share perspectives from Cylake’s Board of Directors. We asked @ravi_lsvp what he sees changing in cybersecurity today. "Twenty years ago, security had become a collection of single-purpose appliances. Nir saw that complexity and helped consolidate an entire layer of the industry around a common platform. What's interesting is that, over time, the industry fragmented again. Large organizations can now have dozens of security vendors, each solving a different problem, collecting different data, and giving the security team another system to manage. I've spent my career watching these cycles play out in enterprise technology. Eventually there comes a point where adding one more product isn't really the answer. You have to look underneath all of it and ask whether the architecture still makes sense. I believe that question matters more now than ever, because we're moving into an increasingly AI-native world where the nature, timing and scale of cyber threats are changing radically. An architecture designed for the last era won't likely hold up in this one. That's what I find compelling about Cylake. Nir and the team aren't trying to build the thirty-first security product. They're going back to the underlying architecture, bringing the data and functions back together, and building it to be forward-looking for what's coming."

AI has made targeted attacks cheaper to build and easier to scale. Defenders need to move faster, and they need the complete picture to do it. Today, that picture is scattered across security products that were never built to work together. Our investors are backing Cylake’s answer: rebuild the architecture from the metal up. @nirzuk founded Palo Alto Networks. Wilson Xu helped build it and led its engineering team. Udi Shamir co-founded SentinelOne. Now they’re building one platform with one data lake, where security and AI run on infrastructure you control. @angusloten covers the surge in early-stage cyber funding, including Cylake’s recent raise, in @WSJ.

Data sovereignty comes down to one thing: control. Where is your data? Who has access to it? And how much control do you have over what happens to it? Cylake’s @MarkatPANW and @renebonvanie break down why these questions matter now more than ever. Dig into the new meaning of data sovereignty: substack.com/@cylake/note/p-…

AI-era cybersecurity needs complete data. Identity, network, cloud, SaaS, endpoint, and everything else generate signals about what’s happening across an environment. But when that data is sampled, separated, or spread across different systems, understanding the full story gets harder. For Katie Helman, that’s what makes cybersecurity such an interesting problem: how do you take an enormous amount of data, make sense of it, and turn it into a picture of the threat landscape people can actually understand? At Cylake, we’re building around complete data: a genuine data lake that ingests security data completely, with detection and workflows running across the complete dataset. Complete data. Complete control. Learn more: Cylake.com

We’re building Cylake with the people who will use it. In Episode 5 of Inside Cybersecurity, Nick Campagna and @renebonvanie go inside Cylake’s Design Partner program and what we’re learning about AI, legacy security stacks, sovereignty, hardware, and more. 🎧 Watch: cylake.substack.com/p/inside…
