Our Story

How we went from enterprise security teams to building the future of application security

Cylent Security was built on one truth: the future of security isn't about protecting systems—it's about protecting applications.

Every modern enterprise runs on them. Every new technology—AI, blockchain, cloud-native—emerges through them. And every attacker knows they are the fastest way to compromise an organization.

In our work with Fortune 100s, we saw it again and again: even when infrastructure looked bulletproof, applications revealed the cracks. The biggest threats weren’t obvious—they hid in the complex ways systems interconnected.

That's why Cylent exists. To shift the balance of power by bringing enterprise-grade application security to the companies building the future. We secure what matters most: the applications that drive business, connect technologies, and carry.
