We are a highly specialized cybersecurity company deeply committed to achieving superior levels of security for our clients. With over two decades of experience, our team has played a critical role in securing the most sophisticated products in the world, including many of the AI/LLM, cloud, software, mobile, and IoT products you use today.

We are not a scanner company. We are the team hired to thoroughly vet security mitigations and find vulnerabilities well after all other design reviews, code reviews, and testing measures have been exhausted. Trusted by the world’s largest organizations, we are known for raising the bar on security through our one-of-a-kind high quality, deep, and thorough testing approach.

What We Stand For

At Casaba, we take your security seriously. We work closely with you to develop highly customized, quality testing programs with qaulity results. We are not the company to call for a check-the-box security or compliance program. We specialize in deep, technical testing that focuses on finding meaningful security risks and exploits, so you can focus on delivering the highest quality products and services on the market. Our goal is to give you complete confidence that your products, platforms, and services are protected against the most important threats you're facing.

A Talented Team with Decades of Experience

Our team brings together high caliber, real world expertise across the full spectrum of systems security. We’ve led pioneering efforts at Microsoft, IBM X-Force, and the U.S. Government, along with leading multinationals. We played key roles in the development of the software Security Development Lifecycle (SDL) and continue to play key roles in ongoing AI/LLM, Cloud and application security testing programs along with core governance programs.

We’re also a good bunch of people. Designers and developers like us because we’re relentless when it comes to making sure their technology is as secure as it can be, but also because we’re generous with our time and knowledge. Part of the reason we’re so effective is our ability to seamlessly integrate with client teams. The other part, of course, is each Casaba team member’s uniquely specialized experience, personality, and work ethic.
