Penetration Tests and Vulnerability Assessments

Every organisation that relies on the security and integrity of its IT systems benefits from ongoing vulnerability assessments instead of one-off penetration tests. The main issue with the traditional pen test is that it’s simply a snapshot in time. And in our opinion, this approach doesn’t offer a great deal of assurance because server, website and software vulnerabilities and exploits are found far more frequently than the usual pen test cycle.

Our work isn’t a destination, it’s more of a journey. Ongoing testing means we can deliver continuous assurance that your network’s perimeter is secure, at a price that compares well to less effective one-off testing.

Continuous Perimeter Assurance

Using the Intruder service, we find your weaknesses before the hackers do. Intruder offers continuous perimeter assurance that helps identify and resolve your vulnerabilities.


Because your systems are always changing, Intruder performs frequent baseline assessments of your digital assets to identify new weaknesses.


Expert penetration testers reduce false positives and investigate potential issues, while the clever use of automation makes regular assessments possible.


Intruder issues notifications for newly released vulnerabilities so you can protect your systems in good time


Intruder is simple to use, and we explain everything in clear, concise language.

The Monthly Baseline

Reports screenshots


We check that no equipment or services have been configured in a way which reduces their security, such as default credentials, or weak encryption.


Where software versions can be identified or fingerprinted, we check whether security patching is current.


Where custom made applications exist, we check that there are no application- layer weaknesses such as SQL Injection, or Cross-Site Scripting.

Emerging Threat Notifications

Intruder checks for new vulnerabilities daily, triaging them to identify the most critical issues.

When a vulnerability is critical, Intruder performs an ad-hoc assessment to detect whether your systems are vulnerable to the specific issue.

If your systems are affected, Intruder sends notifications via an email or text message to a specified phone, or via the Intruder mobile app.
