Penetration Testing
Penetration Software Testing
Cyber threats are constantly evolving. To stay ahead, your business needs more than basic protection, it needs insight. Arc offers in-depth penetration software testing to help uncover hidden vulnerabilities in your software, systems and infrastructure before they can be exploited.


What is penetration testing?
Penetration software testing (or “pen testing”) is a controlled simulation of a cyberattack. It helps evaluate how secure your systems and applications are by identifying vulnerabilities that could be exploited by attackers.
Our testing is designed to:
- Identify security flaws in web applications, APIs, networks and cloud platforms
- Assess your ability to detect and respond to cyber incidents
- Help meet compliance requirements such as ISO 27001, Cyber Essentials Plus and GDPR
- Deliver clear recommendations for reducing risk and improving resilience
All testing is conducted safely, with no disruption to your day-to-day operations.

What we test
Web and application testing – We assess your web platforms, portals and custom software for issues like input validation flaws, authentication weaknesses, and exposed data.
Network and infrastructure testing – Both internal and external networks are tested for weaknesses in configuration, access controls and patching.
Cloud environment assessments – Testing for common misconfigurations and access vulnerabilities in Microsoft 365, Azure and hybrid environments.
Remote access & VPN evaluation – Security analysis of remote work systems, including RDP, VPNs, and endpoint protections.
