Catch vulnerable plugins and themes

Over 30,000 WordPress checks cover core, plugins, and themes. If an update introduces a vulnerability, Intruder flags it with remediation advice.

Scan the pages behind your login

Authenticated scanning covers account pages, dashboards, and checkout, not just the public pages of your site.

Find out if a new vulnerability affects you

When a new vulnerability is disclosed, emerging threat scans check your site automatically, without waiting for the next scheduled scan.

Continuous security for your websites

Get started in minutes

Add your website by URL or IP address, plus login details if you want to scan authenticated pages. Intruder works with WordPress, Drupal, Joomla, Squarespace, and single-page applications.

Protect your site and the server behind it

Each scan checks your site for issues like SQL injection and cross-site scripting, and checks the server hosting it for outdated software, missing patches, and misconfigurations.

Fix and confirm

Results are prioritized by risk, with remediation advice for each issue. Send them to Jira, GitHub, or Azure DevOps, then rescan to confirm the fix worked.

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

One platform. Continuous security.

Does Intruder scan WordPress sites?

Yes. Intruder runs over 30,000 WordPress-specific checks covering core, plugins, and themes. If an update introduces a known vulnerability, Intruder flags it with remediation advice.

What does a website vulnerability scan check for?

Each scan checks your site for application-level issues like SQL injection and cross-site scripting, and checks the server hosting it for outdated software, missing patches, and encryption weaknesses. WordPress sites also get plugin, theme, and core checks. Learn more about web app scanning.

Can Intruder scan pages behind a login?

Yes. Add your login details and Intruder scans authenticated pages like account dashboards, checkout flows, and admin panels, not just the public-facing pages of your site. See the authentication setup guides.
