Tetrel helps engineering teams secure modern systems end to end, from low-level hardware interfaces to production software and cloud environments.

We engage across the product life cycle, from design and architecture through deployment, maintenance, and retirement. We help teams align early with suppliers on clear security requirements, before critical design decisions become costly to change.

We start with a realistic threat model based on how your system is actually deployed, so we can focus on the risks that matter most to you and your users.

We help your team prioritize vulnerabilities according to real-world exploitability and business impact. Our reviews can cover every aspect of the system design and implementation; from RTL, chip configuration, and provisioning, all the way up to the complete firmware, and application stack as necessary. We prioritize the most privileged components, where small flaws can have system-wide impact.

Tetrel was founded in 2023 by practitioners with decades of experience designing, building, and shipping secure hardware and embedded systems.

We combine engineering depth with hands-on offensive security experience to deliver highly tailored projects that meet your needs. We pride ourselves on providing practical recommendations that minimize friction allowing your team can implement fixes within your roadmap and constraints.
