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

Reduce noise

Security teams are stretched and an inbox full of alerts doesn’t help. When Intruder tells you something needs attention, you can trust that it does.

Prioritize what’s being exploited

Intruder combines risk and exploitability signals so you can patch the vulnerabilities attackers are actually going after in your environment

Fix critical risks faster

Get issues that need human oversight to the right people fast with automated triage and 15+ workflow integrations.

Connect and scan

Connect your cloud accounts or enter your targets to start scanning, no agents required. Regular scans run across your web apps and external attack surface. Emerging threat scans kick off automatically when new high-impact vulnerabilities are disclosed or a change is detected in your environment.

Triage and prioritize

Every vulnerability and attack surface issue lands in a single issues view with CVSS score, EPSS exploit likelihood, and KEV status alongside it. Filter by exploit likelihood or specify an EPSS threshold to cut straight to the vulnerabilities most likely to be exploited. AI pentesting agents investigate issues to confirm exploitability and give teams time back.

Route issues to the right team

Get alerts in Slack or Teams when things need fixing. Automatically send issues to Jira, GitHub, or ServiceNow along with all the context and remediation instructions for your engineers. No copy-pasting, no spreadsheet triage.

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

What website security checks does Intruder perform?

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.
