Case Study: Regional Credit Union prevents fraud and secures digital banking launch with Zymr penetration testing

Regional Credit Union cuts phishing clicks from 70% to under 18% with Zymr

The customer, a regional credit union, faced significant security risks ahead of launching its new digital banking platform. Their complex hybrid architecture, authentication weaknesses, and lack of employee training created a high-risk attack surface that could lead to fraud and data breaches. They engaged Zymr for comprehensive penetration testing and a social engineering assessment to identify vulnerabilities and prevent a potentially catastrophic launch.

Zymr executed a blended engagement of external and internal testing, which identified critical flaws including a session token exploit path. They provided a prioritized remediation plan that included enforcing MFA, implementing network microsegmentation, and rolling out mandatory security training. As a result, Zymr's work prevented a high-probability fraud scenario, enabled a secure launch, and reduced phishing click rates from 70% to under 18%. The credit union's improved defenses subsequently blocked three attempted intrusions that matched the test patterns.
