Security for the systems that drive, fly, heal, and run the world.
Vernda is an independent embedded and cyber-physical systems security consultancy led by Tim Brom, with 15+ years finding vulnerabilities in the hardware and firmware that other testing can't reach, from vehicle networks to medical devices to industrial control systems.
Security services built around embedded and cyber-physical systems
Every engagement is scoped and delivered directly by me: no bench of junior consultants, no hand-offs. You get the same person from kickoff to final report.
Design Review & Threat Modeling
Architecture and design-phase security review that catches problems before they're built into silicon or shipped in firmware, aligned with ISO 21434, IEC 62443, DO-326A/356A, and FDA premarket cybersecurity guidance.
Penetration Testing
Hands-on hardware, firmware, and network testing: silicon-level attacks, firmware extraction and analysis, CAN bus, and wireless (WiFi/Bluetooth/RF) attack surfaces on real embedded targets.
Firmware & Hardware Reverse Engineering
Deep-dive reverse engineering across ARM, PowerPC, and x86 platforms to uncover vulnerabilities, backdoors, and undocumented behavior in Linux, Android, and RTOS-based devices.
ICS / OT Security Assessment
Evaluation of network segmentation, field device security, and control system resilience for industrial and operational technology environments against real-world cyber threats.
Security Program Advisory
Ongoing advisory that helps engineering and leadership teams build security in from the ground up, and translates technical risk into decisions the business can act on.
Expert Witness & Litigation Support
Testifying and consulting expert services in automotive and embedded cybersecurity matters, including technical report preparation, deposition, and trial testimony.
AI Security Advisory
Guidance for teams adding AI or ML capabilities to embedded and cyber-physical products: threat modeling for data and model pipelines, secure integration patterns, and risk review before AI ships in a regulated product.
Practitioner-led, standards-fluent, and built for niche cyber-physical systems
Have a system that needs a second, adversarial look?
Whether it's a design review before tape-out, a penetration test before launch, or expert analysis for litigation. I'd like to hear about it.
