Security architecture. Offensive research. Memory-safe tools.
Most of modern cybersecurity is passive compliance — checkboxes that fail to grasp reality.
We go beyond the theatre. We design, we break, we build. From architecture to adversarial research to production-grade code.
About
RevEng3 Ltd is a UK-based security research and architecture boutique. Founded by Gabriel Biondo, we specialise in adversarial research, secure system design, and purpose-built security tooling.
We work with a simple principle: security is not a product you buy — it's a capability you engineer. We help you build it, verify it, and own it.
The Approach
Design. We architect security for mission-critical environments — from bare metal to cloud, platform agnostic, vendor independent. Systems that hold by structure, not by faith.
Break. We verify every architecture from the adversary's perspective. Research and testing that goes beyond automated scans and checkbox audits.
Build. When off-the-shelf isn't enough, we write purpose-built, high-performance security tools. Our software runs in production, hardens perimeters, and generates intelligence.
Transfer. We don't stay forever. We embed the adversarial mindset into your teams and leave you with architectures, tools, and knowledge that work without us.
The Lab
Field-tested research, case evidence, and purpose-built tools.
