Intruder for

See what's exposed inside your network, not just at the perimeter

Build your second layer of defence by securing the apps, devices and servers on your internal network.

Know what’s running

Shadow IT doesn't announce itself. Discover devices and services across your internal network automatically, so you're not relying on an out of date asset inventory.

Cover remote employees

The agent runs on endpoints wherever they are. If someone's laptop is sitting on a home network with an unpatched service, you'll know about it.

Catch misconfigured services

Weak authentication, unnecessary open ports and services running as root are all quiet internal misconfigurations. Intruder flags them.

Install the agent

Deploy Intruder’s lightweight agent on your internal targets. It runs quietly in the background, and works across Windows, macOS, and Linux including remote and off-network machines.

Audit ready reports

Automated reports are generated after every scan and include a high-level summary plus the technical detail auditors need for SOC 2, ISO 27001, HIPAA, PCI DSS, and more.

Prioritize and fix

Every finding is ranked by risk, not just severity. Intruder tells you what's actually exploitable in your environment and gives you step-by-step guidance on how to fix it.

Our customers love Intruder

Emerging Threat Scans are a game changer. They let us stay on top of everything, without hours spent checking sources or reconfiguring platforms. Having full visibility into what's externally exposed has massively increased our confidence.

Pawel Sieradzki

Global IT Director, Brainlabs

If you leave room for doubt in the sales process, you can derail the entire deal. I wanted security to be something we look forward to prospects asking about. Now the security review is one of the fastest parts of the deal stage.

Zach Rattner

CTO & Co-founder, Yembo

I want to take us out of the equation completely from a process perspective. We're not the nagging manager anymore, we just monitor and make sure things are progressing. When my CIO asks where we stand, I can tell him straight away: no highs, no criticals.

Sunil Patel

ISO, River Island

One platform. Continuous security.
