Watch A Real Attack Get Stopped

Pick an incident from our own adversarial testing. Press play and Sentry North walks the attack stage by stage, fires the detection that catches it, and explains every decision in plain language as it happens.

What Is Sentry North

A lightweight agent on every machine, whether that is one laptop at home or a whole office of them. It watches how programs behave, catches threats before they spread, and explains what it found in words you understand. Detection runs entirely on the machine.

01

The full attack story, in plain language.

Every alert arrives with what ran, what it touched, and why it was flagged. The technical evidence sits underneath for anyone who wants the depth. No codes to look up, no dashboards to decode.

02

Evidence-Based Alerts

Every alert arrives with the full attack story in plain language: what ran, what it touched, why it was flagged. The technical evidence sits underneath for anyone who wants the depth.

Your Security Assistant

A built-in assistant your team can talk to. It triages alerts in real time, turns alert storms into single investigations, answers security questions, and walks you through hardening your systems.

It Learns Your Machines

Most tools apply the same rules to every computer. Sentry North watches how each machine normally behaves and builds its own baseline, so it flags what is genuinely out of place on that host.

Telemetry describes threat behaviour, never your files or your identity.

Pipeline

How It Works

Four stages from raw endpoint events to a human-readable threat explanation. Each stage runs on its own. Detection and response never require the cloud.

01
Stage one

Detect

Every meaningful action a program takes is observed in real time, on the endpoint itself, across Windows and Linux. Nothing is shipped to a vendor cloud to be understood.

02
Stage two

Correlate

Related events across your systems are connected into one threat signal. Noise is filtered out before you ever see it.

03
Stage three

Triage

The assistant classifies threats and collapses alert storms into single investigations. Obvious threats are handled automatically; ambiguous ones go to a human.

04
Stage four

Respond

Real-time protection kills malicious processes, quarantines files, and blocks network connections. Canaries catch encryption early.

The difference

Built to Act First

AI-powered attacks are here now. Signature-based tools react after the damage is done. Sentry North acts at the moment of detection, on your machines, in language your team can read.

◎

AI That Helps. Humans Decide.

The assistant aggregates alerts into single investigations. Before anything destructive happens, multiple independent models must agree. If they disagree, a human decides.

Model A · malicious Model B · malicious Model C · malicious
⛔

Protection That Outlasts Your Connection

Detection and response execute on the endpoint, so your protection holds on degraded links and isolated networks. The assistant lights up when you connect. Your security does not depend on it.

☰

Alerts You Can Actually Read

No codes to look up, no dashboards to decode. Every alert tells you what ran, what it touched, and why it matters. Built for teams without a dedicated analyst.

?

Ask It Anything

Why was this flagged? What does this threat mean? How do I lock this down? Your assistant answers in plain language, on any machine it protects, and walks you through hardening steps you can follow.

Sovereignty

Your Data Stays Yours

Most endpoint security tools are cloud-first: detection logic, threat lookups, and telemetry flow through vendor infrastructure. Sentry North runs the important parts on your machines.

The system is built so there is nothing to hand over. Telemetry describes threat behaviour, never your files, your identity data, or your browsing history.

Who it's for

Who It's For

Most small businesses never hire a security person. The job lands on whoever has the least room to say no, and they deserve a tool that speaks plainly to them.

Owners and operators

You run the business and ended up doing the IT. Five to a hundred people, no security hire, and no time to become one.

Whoever inherited "the IT stuff"

The office manager it landed on, along with every other job. You want to know what actually matters, in words that make sense.

The one-person IT team

You are the whole IT department, plus five other things. Sentry North is the second set of eyes that never sleeps.

Your own computers

If all you have is your own machines, you get the same engine. No stripped-down home edition and no minimum number of devices.
