Offensive security · AI research

Found. Proven. Fixed.

We test web apps, APIs and applications the way an attacker would. We also train, fine-tune and orchestrate the language models that now run inside them, so we know where they break.

What we do

Two practices, one standard of evidence

Every claim we make comes with a reproducible request, a trace or a benchmark. That holds whether we are breaking your API or training your model.

Practice 01

Offensive security

Manual, attacker-minded testing of the systems your customers touch.

  • Web application testing

    Authentication, session handling, access control, injection and business-logic flaws, tested by hand and chained into real impact.

    OWASP Top 10 · ASVS

  • API security

    REST, GraphQL and gRPC. Object- and function-level authorization, mass assignment, rate limits and tenant isolation.

    OWASP API Top 10 · CWE-639

  • Application security

    Source code review, threat modelling and architecture review for web, mobile and desktop applications.

Practice 02

AI engineering and research

Models and agents built for a specific job, measured against it.

  • LLM fine-tuning

    Adapting open and hosted models to your domain, data and tone, with evaluation sets agreed before training starts.

    SFT · LoRA / QLoRA · DPO

  • LLM training and research

    Data pipelines, training runs and evaluation harnesses, plus applied research on robustness and model behaviour.

    Pre-training · Evals · Red-team datasets

  • Agent orchestration

    Multi-agent systems with tool calling, memory and guardrails, designed so every action can be traced and every permission is scoped.

Where the practices meet

We red-team the kind of agents we build

LLM features add a new attack surface to your applications: prompts, retrieved content, tools and the permissions behind them. Because we fine-tune and orchestrate models ourselves, we test them from the inside out.

  • Direct and indirect prompt injection
  • Tool and permission abuse in agent workflows
  • System prompt and training data leakage
  • Guardrail and fine-tune hardening, verified by retest

How an engagement runs

From scope to verified fix

  1. 01

    Scope

    We agree on targets, accounts, rules of engagement and what a successful test looks like for you.

  2. 02

    Test

    Manual testing led by engineers, with tooling where it helps. Critical issues are reported the day we find them.

  3. 03

    Prove

    Every finding ships with reproduction steps, evidence, a CVSS score and a fix your developers can apply.

  4. 04

    Fix and retest

    We retest each fix and mark it verified, so your report reflects the current state, not last month's.

Research

The questions our lab is working on

Our engagements keep raising questions a single test cannot answer. We study them in the lab, and what we learn feeds straight back into how we test and build.

R-01API security

Why does object-level authorization keep failing in GraphQL and gRPC APIs?

We map how resolvers and services decide who owns an object, and build test patterns that catch the tenant-isolation flaws scanners miss.

  • Resolver analysis
  • Tenant isolation
  • CWE-639
R-02LLM security

How far can indirect prompt injection reach inside a tool-using agent?

We measure which retrieved content can steer an agent into calling write-capable tools, and which guardrails actually stop it.

  • Agent red-teaming
  • Injection benchmarks
  • OWASP LLM01
R-03Fine-tuning

What does a small domain fine-tune do to a model's safety behaviour?

We compare refusal, leakage and instruction-following before and after SFT and LoRA runs, so clients know what tuning changes.

  • SFT
  • LoRA
  • Refusal evals
R-04Agent orchestration

How should permissions be scoped across a multi-agent system?

We design planner and executor patterns where each agent gets the least access it needs, and every action traces back to a request.

  • MCP
  • Least privilege
  • Action tracing
