How frequently must Shared Hosting Providers examine documented results of scope reviews?

Shared Hosting Providers must examine documented results of scope reviews quarterly because this frequency ensures that they consistently assess and understand the scope of their compliance with PCI DSS requirements. Regular quarterly reviews are critical for identifying any changes in their environment, business processes, or regulatory landscape that could impact their compliance status.

By conducting these reviews quarterly, Shared Hosting Providers can stay proactive in mitigating new risks and adjusting their security posture as necessary. This helps to ensure that any vulnerabilities or compliance issues are addressed in a timely manner, enhancing the overall security and integrity of the systems that handle cardholder data. This frequency aligns with best practices in cybersecurity, where regular assessments are vital to maintaining a robust security program.

Other frequencies, such as monthly, would be overly burdensome and may not provide significant additional benefit, while annually or bi-annually might leave too long of a gap for timely responses to potential issues. Thus, quarterly evaluations strike the right balance for shared hosting providers in maintaining their compliance with PCI DSS.
