Bottom line: Periodic penetration tests fail to identify what actually runs on the network for an entire year – continuous testing cycles are essential for CISOs to ensure compliance and effectiveness.
A two-week penetration test leaves approximately 345 days of unchecked security vulnerabilities in production operations. Sprocket Security demonstrates why continuous security testing is required when attack surfaces are constantly changing.
A conventional penetration test limited to two weeks does not validate the actual security level at any point during the remaining 345 days of a year. During this time, new vulnerabilities emerge through system updates, newly deployed services, configuration changes, and organic infrastructure growth – completely unobserved.
This gap is particularly critical in the banking sector: financial institutions are frequent targets for attackers and are subject to regulatory requirements such as NIS2, which demand continuous validation of resilience. A single test per year can neither document changes in the attack surface nor identify gaps in incident response that emerge between tests.
Continuous security testing – such as through permanent red-teaming activities or automated vulnerability assessments – fills this gap. It ensures that new exposures are identified before they can be exploited, and that changes to the security posture flow directly into defensive strategy.
