Most cybersecurity architectures were built function by function. One tool for visibility, another for detection, a separate one for response. That nature of fragmentation creates limits in how security systems operate at scale. Cylake founder and CEO @nirzuk explains why we are building a unified architecture designed to operate across the full dataset in @pulse2news. Read more: pulse2.com/cylake-profile-ni…

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

Most cybersecurity platforms claim they operate on a complete view of data. @nirzuk argues the opposite. In the latest episode of Inside Cybersecurity with Cylake, Nir explains why cybersecurity data is scattered across disconnected "data puddles" and why that fragmentation creates blind spots across the industry.

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-ni…

32 years ago, @nirzuk helped create the cybersecurity market at Check Point. 21 years ago, he co-founded Palo Alto Networks to consolidate it. Today, he's building Cylake to rebuild the architecture entirely. The tools protecting the world's most critical organizations are working with a fraction of the data they need. And nobody is telling customers that. In the first episode of Inside Cybersecurity, @renebonvanie and Nir break down exactly what's broken and why a single data lake, delivered in hardware, on prem, is the only architecture that can fix it. 🎧 Episode 1 is live now: open.substack.com/pub/cylake…

For a long time, “data” in cybersecurity meant logs and events. Over time, that definition expanded, but most systems still aren’t built to operate on all of it. Without access to the full scope of data, organizations are operating without critical context. Read more from our CEO @NirZuk: linkedin.com/pulse/your-cybe…

Security operators are being asked to make decisions across fragmented systems that were never designed to work together. We think there’s a better way. We’re hiring a Frontend UI Engineer to leverage modern frontend technologies, determine the use of AI for best user outcomes, and provide an immediate impact on the success of a new product line. You’ll join a team led by industry veterans and have the opportunity to shape both the product and user experience from the earliest stages. We’re building for the environments where failure is not an option. Come help us do it. Apply here: jobs.ashbyhq.com/cylake-inc/…

Cylake was built around a different assumption about where cybersecurity is heading. We asked CEO and founder @NirZuk how AI and the scale of data are changing the problem.

AI security requires more data than ever, but the organizations that need it most cannot relinquish control of that data. This is the structural challenge at the center of cybersecurity today. Read our CEO's perspective: substack.com/home/post/p-191…

Cybersecurity tools still operate on isolated “puddles” of data. That model doesn’t work anymore. We are bringing the full dataset into one data lake, so detection, response, and policy can operate together, under your control. @NirZuk talked to @pulse2news about what we’re building at Cylake: pulse2.com/cylake-profile-ni…

Cylake’s Board of Directors includes leaders who have shaped cybersecurity over decades. We asked @MarkatPANW what’s different about the next phase of cybersecurity and what drew him to Cylake.

Organizations often have to throttle the telemetry they share with their cybersecurity applications. The result: AI systems are asked to defend environments without full visibility or context. Read our CEO @nirzuk's thoughts on how we’re approaching this problem: linkedin.com/pulse/sovereign…

The definition of “data” in cybersecurity has changed. Most architectures haven’t. Our CEO @nirzuk explains why that gap is becoming the central challenge in security today: bit.ly/4dXS5A3

How long can your organization operate without full control of its data? That question isn't theoretical. In regulated environments, cybersecurity defenses operate with incomplete context when data is not fully under control. Read more from CEO @nirzuk: bit.ly/4vtQTKU

AI has raised the ceiling for cybersecurity. For AI to be the most effective, it needs unthrottled access to very large amounts of data. However, the most secure environments can’t secure it. That’s the constraint shaping what we’re building at Cylake. linkedin.com/pulse/ai-killin…
