Every week brings another AI analyst, AI SOC, AI agent, or AI assistant. But AI can only work with what it can see. If cybersecurity systems are built on fragmented data and incomplete visibility, AI will inherit those same limitations. Read more in our latest Substack: cylake.substack.com/p/ai-is-exposi…

Are cybersecurity vendors building products around security outcomes, or around cloud pricing models? In the inaugural episode of Inside Cybersecurity with Cylake, CEO @nirzuk explains to @renebonvanie why cloud economics have a greater influence on cybersecurity architecture than many organizations realize.

Cybersecurity wasn't built for the AI era. The industry is racing to deploy AI agents, copilots, and automation. But AI can only work with the data it can see. In Episode 2 of Inside Cybersecurity, @nirzuk and @renebonvanie discuss why AI is exposing long-standing assumptions about cybersecurity architecture, the economics behind AI-powered detection, and why visibility, context, and data remain the foundation of effective security. 🎧 Episode 2 is live now: open.substack.com/pub/cylake/p/a…

How do you protect what you can't fully see? Cybersecurity teams are operating across fragmented datasets, disconnected systems, and incomplete context. In the first episode of Inside Cybersecurity with Cylake, CEO @nirzuk explains why he believes this architectural problem is limiting security outcomes and why the industry needs a new approach. Listen to the conversation with Nir and @renebonvanie: cylake.substack.com/p/why-we-start…

How do you find threats when every security tool only sees part of the picture? Every tool has a piece of the puzzle, but none can see the whole thing. Cylake is bringing security data together in a unified security data platform because better visibility leads to better decisions. See why cybersecurity needs a different architecture: cylake.com

What comes after building one of the most influential cybersecurity companies in the world? @NirZuk joined @CybersecuritySF to discuss the evolution of cybersecurity, lessons learned over two decades in the industry, and the challenges that will shape its next chapter. youtube.com/watch?v=T2juIC…

If you’re looking for a role where every day feels the same, Cylake isn’t for you. We’re in our early days, and things move quickly. People take ownership over what they build and care deeply about getting it right. For some people, that’s exciting. For others, it’s exhausting. If the first reaction sounds more like you, you’ll probably fit in here. Check out our open roles: cylake.com/careers

Every company begins as an idea. What makes someone actually join? We asked Ryan Salsamendi when Cylake went from an interesting concept to "I'm in." The answer was the people behind it and the opportunity to challenge conventional thinking in cybersecurity. Hear why Ryan decided this was something worth building.

Many organizations can’t move security operations to the cloud. Highly regulated environments require a different cybersecurity architecture. Cylake CEO @nirzuk breaks down the thinking behind what we’re building in his interview with @pulse2news: pulse2.com/cylake-profile…

youtube.com/watch?v=o-msCO… I had a great conversation with @nirzuk in the first episode of Inside Cybersecurity with @CylakeAI. The cybersecurity industry has spent years adding more tools and more layers, but the bigger issue may be the architecture underneath them all.

For a long time, “data” in cybersecurity meant logs and events. As that definition expanded, most systems continued to operate on a limited view of data. Cybersecurity is now a data problem. Read my thoughts here: open.substack.com/pub/cylake/p/y…

@CylakeAI formed its Board of Directors. @chandna, @jimgoetz, @MarkatPANW, & I have worked together for over a decade; I’ve seen how they build and scale. Also announcing a strategic investment by In-Q-Tel. Cylake is being built for environments where sovereignty is required.

AI will reshape cybersecurity, but not in the way most expect. It will separate systems that operate on complete data from those that don’t. This is a data access and sovereignty challenge, not an AI one. Cylake is building a platform without those compromises.

[1/4] Sovereignty is the next firewall. In the AI era, the most important security boundary is now about who controls the infrastructure processing your data. 🧵

Generative models can operate on far more data to review code and infrastructure, identify anomalies and vulnerabilities, and prioritize and automate remediation. Does that mean cybersecurity products as we know them are in trouble? I see it differently.

[1/5] Everyone is asking whether AI will replace cybersecurity products. But the real question is whether our current security architecture can even support what AI requires. To understand the effect of AI on cybersecurity, let’s roll back the clock for more than a decade.
