Blast radius

What can one compromised
machine reach today?

Most people cannot answer this about their own network. It takes twenty minutes to set up and a week of watching to find out, it fits inside the trial, and you do not have to change a single firewall rule to get the answer.

How it works

Three steps, no enforcement.

This is the first week of a trial, used deliberately. Nothing here changes a rule on any host.

day 1 · 20 min

01

Install on the ones that worry you

A domain controller, a file server, whatever a laptop can reach. The trial covers ten servers, which is enough to see who reaches them.

days 1–7

02

Let it watch

Learning records what those hosts actually talk to, with the process behind every connection. Nothing is blocked and nothing is changed.

day 7

03

Read the answer

The map shows what those hosts reach. The preview shows what least privilege would close. The gap between the two is your blast radius.

What you'll learn

Usually three uncomfortable things.

We have never run this on an unsegmented network and found nothing.

A path you didn't know existed

Something reaches the domain controller, the backup server or the database that has no business doing so — usually a management tool nobody remembered installing.

A dependency nobody documented

The flow that would have broken production if you had ever got as far as writing firewall rules by hand.

How wide "internal" actually is

The number of hosts a single foothold can talk to is almost always larger than the guess people make before measuring it.

And one reassuring thing

A concrete, ordered list of what to close first — rather than a segmentation project with no obvious starting point.

Questions

Before you install anything.

The reasonable objections to putting an agent on a production server.

Is this safe to run on production?

Learning never enforces. It observes connections and reports them; it does not write a firewall rule unless you turn protection on, which is a separate deliberate action per host.

What does it cost?

Nothing. It fits inside the 30-day trial. If you stop there, you never pay us anything.

What data leaves my network?

Connection metadata — addresses, ports, protocol, the owning process and container, and counts. No packet contents. The full detail is on the trust page.

Can I get this as a document?

Yes. Reports → Evidence pack exports one PDF, or one CSV per section: protection per host and workload, your critical systems and what can reach them, every published rule, and every approval in the period. It's generated from the console, so it shows what's enforced today, not a consultant's summary.

What if I don't want to buy anything afterwards?

Then don't. You keep the answer, and you can write the firewall rules yourself with a much better idea of what they should say. Or use the rest of the trial to protect what you found, and run the same question again on day 30.

Find out this week.

Twenty minutes to install, seven days of watching, and an answer — with three weeks of trial left to act on it.
