What is Network Security Perimeter?

The Network Security Perimeter is a feature designed to enhance the security of Azure PaaS resources by creating a logical network isolation boundary. This allows Azure PaaS resources to communicate within an explicit trusted boundary, ensuring that external access is limited based on network controls defined across all Private Link Resources within the perimeter.

Azure Monitor - Network Security Perimeter - Public Cloud Regions - Update

We are pleased to announce the expansion of Network Security Perimeter features in Azure Monitor services from 6 to 56 Azure regions. This significant milestone enables us to reach a broader audience and serve a larger customer base. It underscores our continuous growth and dedication to meeting the security needs of our global customers. The Network Security Perimeter feature, now available in these additional regions, is designed to enhance the security and monitoring capabilities of our customers' networks. By utilizing our solution, customers can achieve a more secure and isolated network environment, which is crucial in today's dynamic threat landscape.

Currently, NSP is in Public Preview with Azure Global customers, and we have expanded Azure Monitor region support for NSP from 6 regions to 56 regions.
The region rollout has enabled our customers to meet their network isolation and monitoring requirements for implementing the Secure Future Initiative (SFI) security waves.

Key Benefits to Azure Customers

The Network Security Perimeter (NSP) provides several key benefits for securing and managing Azure PaaS resources:

Enhances security by allowing communication within a trusted boundary and limiting external access based on network controls.
Provides centralized management, enabling administrators to define network boundaries and configure access controls through a uniform API in Azure Core Network.
Offers granular access control with NSP rules based on IP addresses or subscriptions.
Includes logging and monitoring capabilities for visibility into traffic patterns, aiding in auditing, compliance, and threat identification.
Integrates seamlessly with other Azure services and supports complex network setups by associating multiple Private Link Resources with a single perimeter.

These characteristics highlight NSP as an excellent instrument for enhancing network security and ensuring data integrity based on the network isolation configuration.
