Critical Vulnerabilities Remediated for Global Car Rental Company

challenge

Expansion Brings Additional Scrutiny

A leading global car rental company recently expanded the footprint of one of their customer-facing applications to make it available outside of the United States. This expansion along with the appointment of a new Chief Information Security Officer (CISO) placed additional scrutiny on application-level security vulnerabilities. Our client didn’t have a dedicated resource to address these issues and was relying on members of their team as they had availability between projects. They needed a faster way to remediate any vulnerabilities without compromising their overall throughput and delivery.

Vulnerabilities Identified

After a number of vulnerabilities were identified including clickjacking, cross-site scripting and cryptography, our team put them into JIRA to manage the backlog of tickets required for remediation. Co-located teams of developers and quality assurance testers provided dedicated and focused effort to quickly remediate and deploy fixes to the legacy code.

Over a 50% Improvement in Time to Remediate

Within four months of engagement, a backlog of 90 vulnerabilities were remediated across a risk management suite of products. Newly discovered vulnerabilities, half of which were classified as high/critical risk, were being remediated in under 20 days; this was down from 45 days, delivering over a 50% improvement in time to remediate.
