Introduction to “anyconnect-android-5.0.01251-release.apk” Software

This standalone APK package delivers enterprise-grade VPN connectivity for Android devices through Cisco’s Secure Mobility Client architecture. Designed for organizations using Cisco ASA 5500-X Series Firewalls or Firepower Threat Defense (FTD) 7.2.1+ platforms, version 5.0.01251 focuses on maintaining compatibility with Android 14 security frameworks while supporting modern authentication protocols like FIDO2 and certificate-based access.
