Offensive Security, Engineered with AI
Penetration testing, red teaming and blockchain audits — and the AI security products we built from that experience. We find what attackers would, and we build what stops them.
Built in-house
Our Products
What breaking systems for a living taught us, turned into products we run ourselves.
AI Security
Attack your AI before someone else does
Attackers already use AI. Our offensive security team tests your LLMs, copilots and agents the same way — and uses AI to keep testing the rest of your estate between annual pentests. Every finding is checked by a person.

Who we are
We break systems for a living. Then we build better ones.
Pyramid Ledger is a London-based security company founded by security researchers and software architects. We test banks, fintechs, exchanges and blockchain protocols the way real attackers would.
We are not only auditors. When a client needs a secure trading platform, an AI gateway or a SOC that proves it works, we build it — and the products on this page are the result.

Provably Hidden Capabilities: Why AI Model Evals Can't Prove a Model Is Safe
New research shows a backdoor can embed an encrypted network inside a model's weights, leaving it hard to elicit or interpret without a secret trigger. If the result holds up, capability evaluations can show that a model is dangerous but cannot show that it is safe.
Project Zero: Build Your Emergency Patch Path Before You Need It
Google Project Zero argues that for most vendors the slow part of an urgent fix is testing and delivery, not finding or writing the patch. It surveys four mechanisms that shorten that window.
Qwen3-Coder Writes Less Secure Code Depending on Who It Is For
Hirundo reports that Qwen3-Coder's code security shifts with the customer named in the prompt, and that removing the model's CCP alignment removes the gap. The findings come from one vendor and are not independently replicated, but they matter for anyone shipping AI-generated code.
