Case Study: Vistara (Tata SIA Airlines) achieves secure, always-on remote access with SonicWall Secure Mobile Access (SMA)

Vistara’s Remote Access Takes Off With Sonicwall

Vistara, a fast-growing airline (Tata SIA/Vistara), faced limits with the SSL VPN on its existing Next-Generation Firewall as expansion drove high CPU utilization and insufficient controls. The airline needed finer-grained remote access — domain and certificate-based authentication, two-factor authentication, and endpoint posture checks — to securely support a distributed, mobile workforce without overloading existing appliances.

To address this, Vistara deployed SonicWall Secure Mobile Access (SMA), including SMA 1000 Series appliances and central management, enabling strong authentication, endpoint posture verification, always-on VPN and centralized monitoring. SonicWall’s solution delivered an in-office experience for remote employees, improved end-user productivity, enhanced protection against critical cyberattacks, and tighter access management without compromising network security.
