Kaiju Security is a veteran-owned offensive security firm. We deliver top-tier penetration testing, red team, physical security and social engineering services at fair prices, performed by senior experts who actually do the work.
We started Kaiju to deliver top-tier penetration testing at affordable prices, and to eliminate the snake oil in cybersecurity: vulnerability scans sold as pentests, inexperienced and burnt out testers on complex engagements, reports that didn't address the real security issues.
Kaiju is a small, agile boutique. Every engagement is led and executed by experienced operators, and you get straight answers about what is broken, how we proved it and how to fix it.
Our leadership team are working hackers and security professionals, not account managers. They scope, lead and perform engagements themselves.
Our team of experts is made up of senior testers, most with ten or more years of experience. We have delivered work for high-profile government and military organizations. The people you meet during scoping are the people who perform the engagement.
