Penetration testing
Find out how an attacker would get in, then close the way in.
A penetration test shows what a real attacker could do with the weaknesses in your environment. We test, explain the findings in plain terms, fix them with our own engineers if you want, and retest to prove they are closed.
Start with a cyber risk assessment
What we test
- External infrastructure: everything reachable from the internet
- Internal network: what an attacker could reach from a compromised device
- Web applications and APIs, following the OWASP Testing Guide
- Microsoft 365, Entra ID and Azure configuration, including identity attack paths
- Wireless networks at your sites
- Phishing and social engineering, alongside security awareness training

How it runs
- Scope: systems, test types, timing and rules of engagement agreed in writing.
- Test: manual testing supported by tools, within the agreed windows and limits.
- Report: an executive summary, and technical findings rated by risk with evidence and clear fixes.
- Fix: your team, or North Ark engineers, close the findings.
- Retest: the findings are tested again to prove they are closed.
Findings that get fixed
A test report is only useful if the findings are closed. Because North Ark also engineers identity, endpoint, network and cloud, we can fix what we find, and the retest shows the evidence your auditors, insurers and customers want to see.
Questions buyers ask
How often should we test?
At least annually, and after major changes such as a new application, a migration or a network redesign. Some contracts and regulators set their own frequency.
Will testing disrupt our systems?
Tests are planned to avoid disruption, with agreed windows, limits and contacts. Anything that could affect availability is agreed in advance.
Can the same company test and fix?
Yes, and it saves time. If you need independence for a particular audit, we can separate the testing and remediation teams, or you can have another firm retest.
Do you test Microsoft 365 and Azure?
Yes. Identity and cloud configuration are where many modern attack paths start, so they are part of our testing.
What do we receive?
A report with an executive summary and technical findings, a debrief with your team, and a retest report once fixes are made.
