Read here about the new features in SecureTransport 5.5 that we have released in the past quarter, why this could be important for your business, and how to make the most of these new capabilities.
SecureTransport introduces additional protections designed for modern, multi‑layered network architectures. Support for Proxy Protocol allows SecureTransport to preserve the original client IP address even when traffic passes through load balancers or reverse proxies. This improves audit accuracy, troubleshooting, and access control decisions in complex network topologies.
Early connection hardening is introduced through restricted login protection at the edge. By preventing high-risk login attempts (such as common administrative usernames) at the edge, SecureTransport can block exploit attempts earlier in the connection flow. This proactive approach helps reduce DDoS exposure, preserve backend resources, and improve overall platform resilience.
Together, these enhancements improve visibility, strengthen access protection, and help organizations operate SecureTransport more securely in demanding network environments.
SecureTransport now supports multiple SSH key types on the server, eliminating the need to choose between supporting only one key type or running secondary key types on non-standard ports. This enhancement simplifies server configuration while providing greater flexibility for mixed client environments.
As a result, organizations can improve compatibility with a broader range of client configurations while simplifying server setup and reducing operational complexity.
Ongoing usability improvements make SecureTransport easier to configure and operate. The Administration Tool now provides clearer visibility into default configuration values, helping administrators better understand system behavior during setup and maintenance. Additional refinements to protocol‑specific (PeSIT) administrative content improve clarity and reduce ambiguity, allowing teams to work more efficiently and manage their environments with greater confidence.
SecureTransport now offers administrators more flexibility to choose the File Tracking filtering style that best suits their workflow and operational requirements. This added control helps teams tailor the experience to their needs while reducing unnecessary system load while improving responsiveness during daily monitoring and troubleshooting activities. This ensures consistent performance as transfer volumes and system activity scale.
SecureTransport continues to align with modern enterprise infrastructure by extending support to Microsoft SQL Server 2025. This allows customers to take advantage of the latest database capabilities while maintaining a supported and future‑ready deployment. Expanded platform support gives organizations more flexibility in their infrastructure strategy and helps ensure long‑term operational stability.
As a reminder, SecureTransport follows the Axway Product Life Cycle policy (PLC 3.1). Security updates and improvements are provided for versions running on platforms in mainstream support. Platforms in extended support receive security updates only. Customers are encouraged to regularly review supported platforms and plan upgrades accordingly to ensure continued access to fixes, enhancements, and the highest level of protection. Fixes for correcting blocking/service-down issues or critical security vulnerabilities are delivered only for update releases in Maintenance status (released within the past 12 months).
As of March 2025, Windows Server 2019 and Microsoft SQL Server 2017 and 2019 are no longer be supported operating systems or databases for SecureTransport.
As of July 2025, TLS v1.0 and TLS v1.1 are no longer allowed by default in the SecureTransport Java security policy to reduce the risk of using an insecure protocol due to misconfiguration. If required for exceptional cases, they can be manually enabled in configuration files on each SecureTransport server.
As of July 2026, Virtual Appliances are no longer supported deployment models for SecureTransport.
As of October 2026, Windows Server 2022 will no longer be supported operating system for SecureTransport.
As of November 2026, PostgreSQL 14 will no longer be supported database for SecureTransport.
As of January 2027, the SDK for SecureTransport 5.5-20220825 is deprecated, as per Official EoS Announcement. Custom Advanced Routing steps created with this SDK will continue to load in the Administration Tool until the SecureTransport 5.5 January 2027 release.
