Tetrel helps cloud providers, server and platform vendors, and device makers secure their systems. We engage at all stages of a product's life cycle, and at all points in the technology stack; from hardware and low-level firmware up through the application software. We are also an approved provider for OCP S.A.F.E. and Caliptra Trademark Auditing assessments.

We are engineers as well as security specialists. Our team has designed and shipped complex hardware and software platforms, so when we find issues, we work with your engineering team on practical solutions that fit your roadmap, constraints, and business drivers.

Our security review process is grounded in how your systems are actually deployed. We start with a threat model based on real-world attacks against similar platforms and your business priorities and risk profile. We use this to focus effort where it matters most.

Modern products blend hardware, firmware, operating systems, mobile applications, and cloud services. Each additional layer introduces assumptions that can be violated in subtle ways. We review system security at every level, from schematic review and chip configuration to firmware design, secure coding practices, and cloud deployment.

Tetrel was founded in 2023 by practitioners with decades of experience designing, manufacturing, and shipping secure hardware and embedded systems, as well as assessing and hardening them.

We deliver tailored services to clients facing the complex challenges of designing and operating modern secure systems. Our combination of engineering experience and security assessment means we can provide prescriptive recommendations that your team can implement with minimal friction. We help prioritize, design, and validate fixes, instead of merely handing over a list of bugs.
