Join 3,000+ companies securing their attack surface with Intruder

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 Discover devices and services across your internal network automatically, so you're not relying on an out of date asset inventory.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

Scan automatically

Scans run on a schedule you control. When a new vulnerability is disclosed, Intruder runs an automated Emerging Threat Scan to check your estate and alerts you with results.

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.

Find what's exposed, fix what matters, and stay ahead of new threats

What do you mean by scanning your website, internally?

Your internal systems can be just as enticing to hackers as your external network so it’s important to test your website for vulnerabilities there too.

When we talk about scanning the website internally, we’re actually talking about scanning the web server that the website is hosted on. Web servers are internet-facing, but any sensitive information connected to them (such as databases) will sit behind a firewall, to prevent them from being reached by unauthorized individuals.

If ‘stuff’ can’t be reached externally, then remote checks won’t work and so you’d need to run local checks. At Intruder, all local/internal checks are performed via an agent which you’d install on the server.  

Internal vulnerability scanning also hunts through your website for missing patches and detects insecure versions of many thousands of software components and frameworks, including operating systems and network devices. Find out more about internal vulnerability scanning.

Can I scan my website if it is built using a CMS, such as WordPress?

Intruder works with many platforms, including WordPress, Drupal, Joomla, Squarespace and more.
