AI agents, real tools
Specialist AI agents for reconnaissance, vulnerability analysis, exploitation and reporting run real security tools against the scope you authorize.
Autonomous CTEM: continuous threat exposure management
AI agents that attack your network and prove what is actually exploitable.
Radius finds what you expose, attacks it inside rules you sign, and proves which vulnerabilities are really exploitable. After you fix a path, it attacks it again. Every run adds to what Radius knows about your environment, so the next one never starts from zero.

What Radius is
and how you buy it.
Radius is the software. Piscium is the team that scopes it, runs it against your environment and hands you the results.
Run by our team
We scope the run with you, agree the rules of engagement in writing and operate Radius. There is nothing to install.
A run or all year
Start with a 2 to 4 week run at a price agreed before anything runs, or keep Radius watching your surface all year. Critical findings reach you the moment they are validated.
Three reports and a retest
Executive, technical and compliance reports, plus a record of every action taken. After you fix a path, Radius attacks it again to confirm it is closed.

From the internet to the system you cannot lose.
Each chain is a path Radius proved hop by hop, with the fixes that break it. These chains are demo data.

How a run works
Radius follows the loop an attacker follows. This is CTEM in practice: after you fix a path, Radius attacks it again.

The surfaceObserve
01
Observe
Maps assets, services, identities and dependencies, including what the inventory missed. Discovery is passive by default.
02
Reason
Builds the attack graph and ranks each path by what it reaches.
03
Attack
Runs the real chain inside the rules you signed.
04
Validate
Confirms how far the chain got and stops before impact. Every action is logged.
05
Report
Delivers the evidence, the fix and the priority in three reports, then attacks the fixed path again.
Safe enough for OT/ICS,
so safe anywhere.
Testing a plant without touching the process.
Discovery is passive, active steps are authorized asset by asset, and the attack stops before impact.
- No writes to controllers
- Per-asset rules of engagement
- A stop button that works mid-run
