Detect and
stop rogue
AI agents

AI agents can act across files, networks and systems. We build the security layer that makes their actions visible, their risk explainable and intervention possible.

From one developer machine to the infrastructure around it.

The security question has changedWhat can this agent actually do?↓
01 / Our thesis

Autonomy needs
an off switch.

An agent does not need malicious intent to cause harm. A compromised tool, a bad instruction or a mistaken action can cross a boundary fast. Security has to follow what the agent can reach and what it actually does.

01

Know what is running

Check executable identity and, where supported, installer provenance instead of relying on a process name alone.

02

See the real exposure

Separate declared permissions, observable activity and reachable resources. Show the evidence and the gaps in coverage.

03

Act with confidence

Give people a clear route from finding to investigation to intervention, with safeguards around the action itself.

02 / Shipping now

Topgent.

A local view of the AI agents on your machine: what they are, what they can reach and when they need attention.

Topgent is our open-source starting point. It finds local agent processes, separates what they declare from what is observed and reachable, and shows the reasons behind a risk finding. Operators can stop a process after its identity is checked again. Analysis runs locally and collects metadata rather than prompts or file contents.

03 / The ambition

Security wherever
agents operate.

Topgent starts with local agents. The larger mission is protection that can travel with autonomous software across personal devices, enterprise estates and the infrastructure in between.

01 / People

Personal devices

Clarity and control for the individual using AI tools every day.

02 / Teams

Workstations

Visibility for developers and security teams as agents enter daily workflows.

03 / Systems

Cloud & servers

Evidence and response for agents running in containers and production environments.

04 / Edge

Embedded & edge

A long-term path toward security across more constrained and distributed systems.

These environments describe our direction, not a claim that Topgent currently supports each one.

04 / Work with us

Build the guardrails
before they’re missed.

We are looking for conversations with people who understand the security shift created by autonomous software.

For investors & strategic partners

Help shape the category.

We are building from a working open-source product toward a broader agent security platform. If that direction matches your thesis, we would like to compare notes.
