Cisco Case Study: Lewisville School District

Safeguarding students and staff at scale

Located northwest of Dallas, the Lewisville Independent School District (ISD) needed an affordable, effective way to secure their 53,000 students and 6,000 staff members. Learn how Cisco’s security architecture, based on Cisco Umbrella and Cisco Firepower Next-Generation Firewall, exceeded their expectations.



  • Safeguard students and staff members from unsuitable content and threats
  • Provide enterprise-level security on a school-friendly budget
  • Improve security visibility and ratings


  • Cut remediation time by 50 percent
  • Improved BitSight score by 70 points
  • Significantly decreased command-and-control and phishing traffic

What they’re saying

The combination of Umbrella and Firepower NGFW enable us to proactively block threats we weren’t blocking before, troubleshoot faster and easier, and know with unprecedented specificity how we’re protecting our students against threats, so they can concentrate on acquiring the skills and knowledge they’ll need after graduation.

Chris Langford, Director of Network, Infrastructure, and Cyber Security, Lewisville ISD
