How Aarsleff Replaced Security Assumptions with Continuous Validation

Stig Lennert of Aarsleff, a construction company in Denmark, explains how Pentera Core replaced assumptions with continuous validation of the organization’s security posture.

Previously, Aarsleff relied on annual penetration tests and general best practices, with no practical way to verify whether security controls were truly effective in a constantly evolving IT environment. By implementing Pentera Core and AD Password Assessment (ADPAS), the team identified risky password reuse among privileged and standard accounts and validated that policy changes were properly implemented and effective. Instead of waiting a year to measure progress, Aarsleff can now continuously test and confirm that security improvements are delivering measurable results.

Pentera enables the organization to proactively reassess its defenses as the environment changes, ensuring that security enhancements are validated in real time rather than assumed to be working.
