Agentic AI security

Build AI agents you can understand and trust.

We build agentic systems with security designed in from the start. We help teams understand what their agents can do, reduce what can go wrong, and notice quickly when it does. No system is ever fully secure, but a good one is hard to misuse and quick to catch when it slips.

Autonomy, earned not assumed

An agent that can act on its own is a new kind of insider.

So we treat it like one. Before you hand it that freedom, and the whole time it holds it, we ask three plain questions: what can it reach, what could it be tricked into doing, and what should it never be allowed to do?

We answer with a structured model of how agents fail, mapped to the frameworks the field is building around it: OWASP's work on LLM and agentic security, and MITRE ATLAS. So it holds up beyond our own judgement.

Securing agentic AI

A background check for your AI agents.

Before an agent goes live, and while it runs, we map its attack surface, threat-model the autonomy, design guardrails and least-privilege identity, red-team it the way an attacker would, and put monitoring around it so misbehaviour shows. A background check doesn't end at the hire.

We build these systems ourselves, so we know where they tend to break. That is the difference between securing agents from the outside and securing them from the builder's seat.

01

Threat-model the autonomy

Trust boundaries where an agent calls tools, reads untrusted data, and holds memory. Where the risk actually sits.

02

Guardrails & identity

Tool allow-listing, least-privilege agent identity, prompt-injection defence, and policy-bound autonomy that holds up without wrecking the product.

03

Red-team & evaluate

Jailbreaks, indirect injection, exfiltration and tool-abuse chains, turned into a regression suite your CI can keep running.

04

Monitor & govern

Runtime visibility for when an agent drifts, and audit-ready evidence mapped to SOC 2, ISO 27001 and ISO 42001.

Built

Securing agents starts with building them.

The security work is grounded in a long habit of building and research: agents, harnesses, infrastructure, and experiments that tend to arrive early. A selection.

Personal assistant agent & harness

A personal AI assistant, and the harness it runs on. Built to improve itself over time, with guardrails from the start.

Oversight from any device

Watch and control your agents from any device, down to the Apple Watch, or from smart glasses while you work.

GRC & audit automation

A private RAG pipeline that speeds up governance, risk, and audit work across your own documents.

AI red-teaming

Red-teaming AI models to find where they give up what they shouldn't, drawing on a background in offensive security (OSCP).

Workflow augmentation

Automating admin work, and building image, audio, and text tools where the payoff is clear.

Sovereign inference

Frontier open models on your own hardware, local or cloud, tuned for the job, with nothing leaving your environment.

Sovereign stack

From silicon to software, under your control.

When the work calls for it, we build the whole column rather than a wrapper on someone else's API. Every layer is yours to inspect, host, and certify.

Security and governance is not a layer; it runs the height of the stack.

L4

Agents & Orchestration

Multi-agent workflows, tool use, and policy-bound autonomy with full traceability.

L3

Fine-tuned Models

Domain models tuned, aligned, and evaluated on your data, then owned, hosted, and kept.

L2

Inference & Runtime

Private inference, retrieval, and search: frontier open models served on your own hardware, air-gapped where you need it.

L1

Hardware & Silicon

On-prem and sovereign-cloud compute, provisioned and hardened for accelerated workloads.

Track record

Two decades shipping security that scales.

Our work spans fast-moving startups and heavily regulated enterprises: keeping the former quick on their feet with security that scales, and helping the latter modernise with cloud-native compliance that accelerates rather than obstructs.

Built security functions and architectures from the first hire up, with automated auditing and continuous monitoring proven across multiple certifications.

Research & direction

Putting a number on the blast radius.

Agentic systems are shipping faster than anyone can test them. The question that matters is not how clever a model is, but how much damage it can do once it is wired into real tools.

Frontier labs answer that behind closed doors. We are working toward the opposite: a transparent, self-hostable way to measure an agent's blast radius, exercised against models we deliberately train to misbehave and keep in-house, so the answer is something you can run and check rather than a promise to trust.

Responsible research

Evaluation research, not offensive enablement. Adversarial models stay in controlled, isolated environments — never released as public weights, never pointed at live third-party systems — and the work follows responsible-disclosure norms. The line between measuring risk and creating it stays firm.

Agentic blast-radius benchmark

A transparent, self-hostable way to run a model inside real agent harnesses and measure how much damage it could do, mapped to OWASP and MITRE ATLAS.

Adversarial model research

Small open models trained to misbehave on purpose, kept in a controlled environment, used to test agent defences honestly rather than in theory.

Mechanistic interpretability

Reading what a model represents at the circuit level. A direction we are building toward.

Neuron surgery: why security needs AI interpretability

Malware is rewriting itself at runtime with LLMs. As models embed into software supply chains, understanding their internals becomes a security question. How do you run a background check on your AI agent?
