to complete captive portal requirements (e.g., at hotels or airports) even when network access is otherwise blocked by "Always On" policies. Proxy Lockdown Behavior Change: For Windows 10 (version 1703 or later), AnyConnect now hides and locks down the system proxy tab
AnyConnect 4.7.x is incompatible with HostScan releases prior to HostScan 4.3.05050 . It is, however, backwards compatible with 4.3.05050 and compatible with HostScan 4.7.x. If the versions are incompatible, the VPN connection will not establish, ensuring that end-of-life security tools cannot bypass network access controls.
As modern enterprises transition from traditional remote access architectures to unified zero-trust environments, understanding the capabilities, deployment strategies, and design limitations of this foundational build remains vital for network administrators maintaining heritage IT infrastructure.

: Includes optional modules for Cisco Umbrella Roaming, ISE Posture, and Network Visibility to assess endpoint compliance and threat detection. Security and Vulnerability Management
Rather than functioning purely as a standard Virtual Private Network (VPN) utility, the Cisco AnyConnect client uses a modular framework that consolidates network access control and endpoint security into a single platform.
: This feature addressed a common and frustrating problem for remote workers. A "captive portal" is the web page you see when connecting to public Wi-Fi in hotels, airports, or coffee shops, requiring you to accept terms or log in before accessing the internet. A "catch-22" situation could arise when a VPN client with an "Always-On" policy would block all network access until the VPN connection was established, which itself required internet access through the captive portal.
