About Pulsosec
15 Years. 300+ Clients. Zero Major Breaches Under Our Watch.
Founded by practitioners, led by engineers, trusted by the enterprises that protect critical data.
Our Mission
Make enterprise-grade security accessible to every organisation that protects critical data.
Founded in 2009 by practitioners from the NSA, FBI Cyber Division, and Fortune 50 security teams, Pulsosec was built on a simple premise: organisations shouldn't need a 500-person security department to defend against nation-state-level threats.
We bring the depth of experience that was once reserved for the largest financial institutions and government agencies — and we deliver it with the responsiveness and directness that only a specialist firm can offer.
Integrity First
We tell clients what they need to hear, not what they want to hear. Honest assessment over comfortable reassurance.
Engineer-Led
Every engagement is led by a senior practitioner. No junior analysts, no account managers running technical calls.
Client Partnership
We build long-term relationships, not transaction-based engagements. Your security posture improves continuously.
Adversarial Thinking
We think like attackers so you don't have to. Every recommendation is grounded in real-world threat actor behaviour.
