Case Study: PROSA establishes trust with a major U.S. bank by improving cybersecurity posture with BitSight Security Ratings and Forensics

PROSA Leverages BitSight® to Become a Trusted Third Party for a Large American Bank

PROSA, a payments services provider handling more than 70 million cardholder transactions annually, needed to prove its cybersecurity posture after a large American bank reviewed its BitSight Security Ratings and found vulnerabilities. To measure progress and establish trust, PROSA used BitSight’s Security Ratings platform, BitSight Forensics, and the Enable Vendor Access (EVA) feature to gain visibility into findings and collaborate with the bank.

With BitSight, PROSA’s team investigated and remediated issues—uncovering open ports and compromised systems that internal tools had missed—using daily ratings and a 12-month historical view to track improvements. The result: rapid remediation, documented and repeatable security improvements reported to the bank, and ongoing continuous monitoring with BitSight that helped PROSA become a trusted third‑party partner.
