Case Study: Leading Corporate Email Hosting Company achieves enhanced data protection and regulatory compliance with QASource

Leading Email Host Enhances Data Protection With Security QA Testing

Leading Corporate Email Hosting Company, a leader in corporate email hosting with more than 2,000 customers and roughly $50M in annual revenue, faced rising risk from data leaks and cyberattacks threatening the hundreds of thousands of emails it processes daily. To lock down its application security and meet regulatory obligations, the company engaged QASource for security QA testing and compliance support.

QASource implemented a comprehensive security QA program—selecting tools such as Fiddler, Apache JMeter, AppScan and NTOSpider, delivering compliance training, and performing deep testing (over 10,000 scans including XSS, SQL injection and directory indexing). QASource’s work uncovered and resolved more than 70 high‑priority security issues and 115 regulatory compliance issues, delivering stronger, more secure email hosting for customers and employees plus full documentation for the client’s in‑house team.
