What our customers say

We were in need of a testing product that would test from the inside out and outside in. That's what first attracted us to Intruder. The product is well laid out with a clear, concise Cloud interface.

I really like how Intruder integrated with our internal company comms (ie Slack), this meant we stayed on top of the notifications it produced. Time is critical when it comes to security vulns so it’s helpful to have messages from Intruder next to our daily workflows.

Will Lewis

Senior Engineering Manager,

Not only does Intruder save me time and money, but it helps us close deals. Some customers are now requiring regular network scans in order to do business with SaaS companies. By utilizing Intruder we're able to meet client demand and ensure we're doing the right thing to keep our customer trust.

Justin Unton

Head of Information Security at Litmus

Auto-discovery, a very proactive set of scans against emerging threats and solid notifications. Intruder is a tool I can forget about unless I need to. Rock solid UX.

Is there a difference between a website and a web application?

A website (eg. intruder.io) doesn’t do much; there’s very little interactivity, no logging in – in short, it’s a collection of static web pages. A web application that can be viewed within a browser can have a lot of features/functionality and is like a piece of software (eg. portal.intruder.io).

What do you mean by scanning your website, internally?

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).

What vulnerabilities would you typically find on a website? 

With so many vulnerabilities out there, it's impossible to list them all, but this article should give you an understanding of the different types of weaknesses we can detect, and how we do it.

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

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

Which plan should I choose if I just want to scan my website?

Choose our Essential or Pro plan to externally scan your website. If you are looking at our internal vulnerability scanning capability, this is only available to our Pro and Vanguard subscribers. Visit our pricing page to learn more.

What license should I buy for a website that doesn’t have a login-page?

Buy any of our Essential or Pro plans that cover infrastructure licenses by default. Visit our pricing page to learn more.
