Penetration Testing

Penetration Software Testing

Cyber threats continually evolve. To stay ahead, your business needs more than just 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 cyber attack that helps evaluate how secure your systems and applications are by identifying vulnerabilities that might well be exploited by the attacker.

Our testing is designed to:

  • Identify security vulnerabilities in various aspects: web applications, APIs, networks, and cloud platforms.
  • Assess your ability to detect and respond to cyber incidents
  • Help meet the compliance requirements of ISO 27001, Cyber Essentials Plus and GDPR.
  • Provide clear recommendations to reduce risk and improve resilience.

All testing is safely conducted without interfering with your daily operations.

Cloud environment assessments: Testing for common misconfigurations and access vulnerabilities in Microsoft 365, Azure, and hybrid environments.
