Multi-layer protection in Windows Server 2025
In the face of growing cybersecurity threats and rising incident costs, security remains a top priority. Windows Server 2025 introduces enhanced protection features through Secured-core Server technology and secure connectivity.
Secured-core server
Secured-core Server uses TPM 2.0 and System Guard to create a chain of trust from firmware to the operating system. Virtualisation-Based Security (VBS) and Hypervisor-protected Code Integrity (HVCI) isolate critical processes, protecting against the most sophisticated hardware and software-level threats.
Secure connectivity with key resources
Enhanced HTTPS support ensures more secure connections, while AES-256 encryption for the SMB protocol protects file transfers with the highest level of security. SMB protocol improvements ensure that data in transit is always protected with cutting-edge cryptographic standards.
Windows Server 2025 modern application platform
Give your developers and IT specialists the ability to build applications quickly and confidently. With support for up to 48 TB of memory and 2048 logical cores, Windows Server 2025 is the ideal foundation for modern applications.
Accelerated container image downloads
Container image sizes have been significantly reduced. Group Managed Service Accounts (gMSA) have been improved for greater security, IPv6 support is complete, and integration with Calico for Kubernetes container networking is native.
Easier .NET application deployment
Windows Admin Center simplifies the containerisation of existing .NET applications. Migration to Azure Container Registry is integrated, enabling you to modernise legacy applications without rewriting code. The guided process transforms traditional applications into containers ready for deployment.
