•Active User Session API Enhancements: The Active User Sessions REST API has been enhanced to support filtering session data based on user, see Active User session.

•WebSocket Support Through HTTP(S) Proxy: Ivanti Connect Secure (ICS) now supports establishing and maintaining WebSocket connections to backend application servers through a configured HTTP(S) web proxy. This enhancement enables WebSocket-based applications to function seamlessly in environments where proxy routing is required by organizational policies.

•Automated Certificate Management Environment (ACME) Support: Ivanti Connect Secure now supports the Automated Certificate Management Environment (ACME) protocol to automate certificate requests, domain validation, certificate issuance, and certificate deployment on the designated interface, see ACME Server.

•Default VLAN ID Support with IPv6 on Internal Interfaces: Ivanti Connect Secure now supports the use of the Default VLAN ID when IPv6 is configured on the Internal Interface. This enhancement ensures that the Default VLAN ID remains available and functional when both IPv4 and IPv6 are enabled, see Default VLAN ID.

•Bulk ACL Management Using REST API: Ivanti Connect Secure now supports bulk management of Access Control Lists (ACLs) through REST API. Administrators can create, update, and delete multiple ACLs in a single API request, improving scalability and operational efficiency for large enterprise and MSP deployments, see Create Multiple ACLs .

•Postman Collection for ICS REST APIs: Ivanti Connect Secure now provides a Postman collection for publicly available REST APIs, enabling administrators and developers to quickly explore, test, and integrate ICS APIs using the Postman client, see Postman Collection.

•OAuth Group Claims for Role Mapping: Ivanti Connect Secure (ICS) now supports role mapping based on group claims received from OAuth providers such as Microsoft Entra ID (Azure AD). Administrators can use group information included in the OAuth ID Token or UserInfo response to assign user roles within ICS user realms, see OAuth Group Claims Role Mapping.

•HTTP/2 Ingress Support in NGINX: NGINX has been enhanced to support HTTP/2 for inbound client connections. HTTP/2 provides improved connection efficiency and performance through multiplexing and optimized protocol handling, see HTTP Protocol Configuration.

•Secure Boot and vTPM Support: GCP, AWS platform now provides secure boot support with vTPM functionality, enhancing security and integrity for virtual machines, see Secure Boot with TPM/vTPM.

•Virtual appliance platforms: Added support for the new virtual appliance platforms ISA-V 4500, ISA-V 6500, and ISA-V 8500 in Ivanti Connect Secure (ICS) version 25.1.3.0, see ISA VA Supported Platforms.

•Host Header Validation: Ivanti Connect Secure now provides a console-based option to disable Host Header Validation on the management interface. This enhancement supports deployments where the management interface is accessed through Network Address Translation (NAT), helping ensure administrative access in environments where Host Header Validation may otherwise block requests, see Host Header Validation.

•Configurable Certificate Challenge Timeout: Administrators can now configure the maximum interval between certificate challenge exchanges during the pre-authentication phase of certificate-based authentication. The timeout value can be set from 1 to 4 minutes, with a default value of 1 minute, see Certificate Challenge Timeout.

•UI Enhancement for Compliance Report: Failed policies now display the corresponding failed rule names and failure reasons. Additionally, Host Check results are presented in a separate column to improve visibility and reporting clarity, see Using Host Checker Reports and Logs.
