Update ID: 496002 Data source: Azure Updates API
Categories: Launched, Networking, Azure Private Link, Compliance, Management, Security, Services
Summary:
What was updated
Azure has announced the general availability of the Network Security Perimeter feature.
Key changes or new features
Network Security Perimeter enables organizations to create a logical network isolation boundary around Azure PaaS resources such as Azure Storage accounts and SQL Database servers that are deployed outside of their virtual networks. This boundary restricts public network access to these resources, enhancing security by limiting exposure to only trusted networks or IP ranges. It provides granular control over inbound traffic to PaaS services without requiring them to be inside a virtual network.
Target audience affected
This update primarily impacts developers and IT professionals managing Azure PaaS resources who require enhanced network security controls. It is especially relevant for security architects and network administrators responsible for securing data and services in Azure.
Important notes if any
The feature supports key PaaS services and helps organizations meet compliance and security requirements by reducing the attack surface of publicly accessible resources. Users should evaluate their existing network security configurations and consider adopting Network Security Perimeter to enforce stricter access controls on PaaS endpoints. Further details and configuration guidance are available in the official Azure update documentation.
Details:
The Azure update titled “Generally Available: Network security perimeter” introduces a critical capability enabling organizations to establish a logical network isolation boundary around Platform as a Service (PaaS) resources such as Azure Storage accounts and SQL Database servers that reside outside their virtual networks. This feature addresses the challenge of securing PaaS services that are inherently internet-accessible by default, thereby enhancing the security posture of cloud deployments.
Background and Purpose:
Traditionally, securing Azure PaaS resources involved using virtual network (VNet) service endpoints, private endpoints, or firewall rules to restrict access. However, these methods either require complex network configurations or do not fully isolate PaaS resources from public internet exposure. The network security perimeter feature was developed to provide a simpler, more effective way to logically isolate PaaS services without necessarily placing them inside a VNet, thereby reducing attack surfaces and aligning with zero-trust security models.
Specific Features and Detailed Changes:
This update enables organizations to define a network security perimeter that acts as a boundary around PaaS resources. Within this perimeter, access is restricted to trusted networks or identities, effectively blocking unauthorized public internet traffic. The perimeter supports granular policies that can specify which subnets, IP ranges, or Azure services are allowed to communicate with the protected PaaS resources. This is a shift from solely relying on network-level controls to a more integrated, policy-driven approach.
Technical Mechanisms and Implementation Methods:
The network security perimeter leverages Azure’s underlying network infrastructure and identity services. It integrates with Azure Private Link and Azure Firewall Manager to enforce access policies. When configured, the perimeter intercepts incoming traffic to PaaS resources and evaluates it against defined rules. Traffic originating outside the perimeter or from unauthorized sources is denied. Implementation involves defining the perimeter scope via Azure Portal, CLI, or ARM templates, specifying allowed network ranges and identities, and associating the perimeter with targeted PaaS resources. The feature also supports monitoring and logging through Azure Monitor and Azure Security Center for compliance and auditing.

Integration with Related Azure Services:
This feature complements Azure Private Link by providing an additional logical boundary beyond private endpoints. It integrates with Azure Firewall Manager for centralized policy enforcement and with Azure Monitor and Security Center for visibility and threat detection. It also works alongside Azure Active Directory conditional access policies to enforce identity-based restrictions, creating a layered defense model.
In summary, the generally available network security perimeter feature empowers IT professionals to define and enforce logical network isolation boundaries around Azure PaaS resources deployed outside VNets, enhancing security by restricting access to trusted networks and identities through integrated policy controls, thereby simplifying secure cloud architecture and supporting compliance requirements.
Published: August 05, 2025 16:00:50 UTC Link: Public Preview: Azure Virtual Network Manager mesh now supports 5,000 virtual networks
Update ID: 499782 Data source: Azure Updates API
Categories: In preview, Networking, Azure Virtual Network Manager, Features, Management, Services, Regions & Datacenters, Pricing & Offerings
Summary:
What was updated
Azure Virtual Network Manager (AVNM) mesh connectivity now supports grouping up to 5,000 virtual networks in public preview.
Key changes or new features
The mesh topology enables automatic bi-directional connectivity between every virtual network within the mesh, simplifying large-scale network management. This update significantly increases the scale from previous limits, allowing enterprises to manage and connect thousands of VNets across supported Azure regions seamlessly.
Target audience affected
Developers and IT professionals managing large Azure network environments, especially those requiring scalable, automated connectivity across multiple VNets for complex applications or multi-region deployments.
Important notes if any
This feature is currently in public preview, so users should evaluate it in non-production environments first. Availability is limited to supported Azure regions. Users should monitor Azure updates for GA announcements and review any preview limitations or known issues documented by Microsoft.
Details:
The recent public preview update for Azure Virtual Network Manager (AVNM) significantly enhances its mesh connectivity capabilities by increasing the maximum number of virtual networks (VNets) that can be grouped within a single mesh topology from previous limits to up to 5,000 VNets in supported Azure regions. This advancement is designed to simplify and scale network management and connectivity in large, complex cloud environments.
Background and Purpose
Azure Virtual Network Manager is a centralized network management service that enables IT professionals to manage connectivity and security policies across multiple VNets at scale. Prior to this update, mesh connectivity topologies supported fewer VNets, which limited the ability to efficiently manage large-scale network architectures, especially in enterprises with numerous VNets spanning multiple subscriptions or regions. The purpose of this update is to address scalability challenges by allowing a much larger number of VNets to be connected in a fully meshed topology, thereby facilitating seamless, bi-directional communication between all VNets within the mesh.
Specific Features and Detailed Changes
Technical Mechanisms and Implementation Methods
AVNM leverages Azure’s underlying network infrastructure and automation APIs to orchestrate connectivity policies across VNets. When a mesh topology is created or updated:
