WHY ORGANIZATIONS CHOOSE US

Toptal in Action

Discover the cutting-edge benefits our clients enjoy from the global Toptal network.

Toptal ensures world-class security for nonprofit children’s hospital trust.

Challenge: Nonprofit hospitals often struggle with limited security budgets and bandwidth while processing high volumes of protected healthcare information on a daily basis. In the wake of a breach, a leading US pediatric hospital needed to restructure its security infrastructure. However, budget constraints and inflexible vendors posed major roadblocks.

Solution: Toptal introduced an experienced information security team, including a virtual chief information security officer (vCISO) with decades of experience evaluating and developing security solutions. The Toptal team carried out a thorough analysis of the hospital’s current infrastructure, teams, and procedures.

Outcome: Thanks to the roadmap developed by Toptal’s team, the client now has a strong security presence that will help protect patient data and donor information from future cybersecurity threats. The hospital is better prepared than ever to ensure the safety of sensitive information for years to come.
