Industry-Wide Certificate Changes Impacting Azure App Service Certificates
Executive Summary In early 2026, industry-wide changes mandated by browser applications and the CA/B Forum will affect both how TLS certificates are issued as well as their validity period. The CA/B Forum is a vendor body that establishes standards for securing websites and online communications through SSL/TLS certificates. Azure App Service is aligning with these standards for both App Service Managed Certificates (ASMC, free, DigiCert-issued) and App Service Certificates (ASC, paid, GoDaddy-issued). Most customers will experience no disruption. Action is required only if you pin certificates or use them for client authentication (mTLS). Update: February 17, 2026 We’ve published new Microsoft Learn documentation, Industry-wide certificate changes impacting Azure App Service , which provides more detailed guidance on these compliance-driven changes. The documentation also includes additional information not previously covered in this blog, such as updates to domain validation reuse, along with an expanding FAQ section. The Microsoft Learn documentation now represents the most complete and up-to-date overview of these changes. Going forward, any new details or clarifications will be published there, and we recommend bookmarking the documentation for the latest guidance. Who Should Read This? App Service administrators Security and compliance teams Anyone responsible for certificate management or application security Quick Reference: What’s Changing & What To Do Topic ASMC (Managed, free) ASC (GoDaddy, paid) Required Action New Cert Chain New chain (no action unless pinned) New chain (no action unless pinned) Remove certificate pinning Client Auth EKU Not supported (no action unless cert is used for mTLS) Not supported (no action unless cert is used for mTLS) Transition from mTLS Validity No change (already compliant) Two overlapping certs issued for the full year None (automated) If you do not pin certificates or use them for mTLS, no action is required. Timeline of Key Dates Date Change Action Required Mid-Jan 2026 and after ASMC migrates to new chain ASMC stops supporting client auth EKU Remove certificate pinning if used Transition to alternative authentication if the certificate is used for mTLS Mar 2026 and after ASC validity shortened ASC migrates to new chain ASC stops supporting client auth EKU Remove certificate pinning if used Transition to alternative authentication if the certificate is used for mTLS Actions Checklist For All Users Review your use of App Service certificates. If you do not pin these certificates and do not use them for mTLS, no action is required. If You Pin Certificates (ASMC or ASC) Remove all certificate or chain pinning before their respective key change dates to avoid service disruption. See Best Practices: Certificate Pinning. If You Use Certificates for Client Authentication (mTLS) Switch to an alternative authentication method before their respective key change dates to avoid service disruption, as client authentication EKU will no longer be supported for these certificates. See Sunsetting the client authentication EKU from DigiCert public TLS certificates. See Set Up TLS Mutual Authentication - Azure App Service Details & Rationale Why Are These Changes Happening? These updates are required by major browser programs (e.g., Chrome) and apply to all public CAs. They are designed to enhance security and compliance across the industry. Azure App Service is automating updates to minimize customer impact. What’s Changing? New Certificate Chain Certificates will be issued from a new chain to maintain browser trust. Impact: Remove any certificate pinning to avoid disruption. Removal of Client Authentication EKU Newly issued certificates will not support client authentication EKU. This change aligns with Google Chrome’s root program requirements to enhance security. Impact: If you use these certificates for mTLS, transition to an alternate authentication method. Shortening of Certificate Validity Certificate validity is now limited to a maximum of 200 days. Impact: ASMC is already compliant; ASC will automatically issue two overlapping certificates to cover one year. No billing impact. Frequently Asked Questions (FAQs) Will I lose coverage due to shorter validity? No. For App Service Certificate, App Service will issue two certificates to span the full year you purchased. Is this unique to DigiCert and GoDaddy? No. This is an industry-wide change. Do these changes impact certificates from other CAs? Yes. These changes are an industry-wide change. We recommend you reach out to your certificates’ CA for more information. Do I need to act today? If you do not pin or use these certs for mTLS, no action is required.

Today, we are announcing the launch of the DCasv6 and ECasv6 series of confidential virtual machines (CVMs) in Azure Government. Azure Government: Compliant, Hyperscale, Sovereign Cloud Azure Government was designed to remove the constraints that have historically limited federal cloud adoption by delivering hyperscale innovation without sacrificing regulatory certainty. Supporting over 180 services, Azure Government allows customers to consume advanced cloud capabilities without having to individually validate service availability or compliance. It is a complete end-to-end platform, delivering identity, DevOps, and services as commercial Azure, while operating entirely within accredited boundaries. Confidential virtual machines address one of the barriers to multi-tenant cloud adoption: When deployed on Azure Government, Confidential VMs combine physical isolation, sovereign operations, and hardware-enforced cryptographic isolation into a single execution environment. This enables customers to get additional protections from insider threats. At its core, Azure Government runs the same Azure codebase that powers Microsoft’s commercial cloud, providing access to compute, networking, storage, data, and AI services. DCasv6 and ECasv6: Confidential virtual machines in Azure government cloud The DCasv6 and ECasv6-series virtual machines built on 4th Generation AMD EPYC™ processors are the first in Azure Government to implement AMD SEV-SNP. This generation introduces several controls that change both security posture and operational readiness: Hardware-Enforced Memory Isolation: AMD SEV-SNP provides full, AES-256 encrypted memory with keys generated and managed by the onboard AMD Secure Processor. Online key rotation: Support for the online key rotation with the introduction of Virtual Machine Metablob disk (VMMD). Programmatic Attestation for Audit and Zero-Trust: Before provisioning any workload, customers can perform an attestation. This cryptographic procedure validates the integrity of the hardware and software, producing a signed report that proves the VM is a genuine confidential instance. Confidential OS Disk Encryption with Flexible Key Management: Cryptographic protection extends beyond runtime memory to the operating system disk itself. The disk's encryption keys are bound to the VM's virtual Trusted Platform Module (vTPM), which is protected within the TEE. Customers can choose between platform-managed keys (PMK) for simplicity and regulatory ease, or customer-managed keys (CKM) for full, sovereign control over the key lifecycle - a common requirement for the most stringent compliance regimes. Conclusion With the DCasv6 and ECasv6-series virtual machines now generally available in Azure government regions, customers can modernize their infrastructure deployments through confidential computing which replaces implicit trust with cryptographic isolation, and when deployed on Azure Government’s sovereign cloud within physically isolated data centers, it enables agencies to modernize at operational speed without compromising control. Azure Government is in a unique position to deliver the full operational depth of a hyperscale cloud, from identity and DevOps to monitoring and edge execution, inside an environment purpose-built for federal compliance. When combined with the latest Confidential VMs, customers gain secure infrastructure built on a platform where agility, visibility, and trust reinforce each other.

Public Preview: Azure Monitor pipeline transformations
Overview The Azure Monitor pipeline extends the data collection capabilities of Azure Monitor to edge and multi-cloud environments. It enables at-scale data collection (data collection over 100k EPS), and routing of telemetry data before it's sent to the cloud. The pipeline can cache data locally and sync with the cloud when connectivity is restored and route telemetry to Azure Monitor in cases of intermittent connectivity. Learn more about this here - Configure Azure Monitor pipeline - Azure Monitor | Microsoft Learn Why transformations matter Lower Costs: Filter and aggregate before ingestion to reduce ingestion volume and in turn lower ingestion costs Better Analytics: Standardized schemas mean faster queries and cleaner dashboards. Future-Proof: Built-in schema validation prevents surprises during deployment. Azure Monitor pipeline solves the challenges of high ingestion costs and complex analytics by enabling transformations before ingestion, so your data is clean, structured, and optimized before it even hits your Log Analytics Workspace. Check out a quick demo here - If the player doesn’t load, open the video in a new window: Open video Key features in public preview 1. Schema change detection One of the most exciting additions is schema validation for Syslog and CEF : Integrated into the “Check KQL Syntax” button in the Strato UI. Detects if your transformation introduces schema changes that break compatibility with standard tables. Provides actionable guidance: Option 1: Remove schema-changing transformations like aggregations. Option 2: Send data to a custom tables that support custom schemas. This ensures your pipeline remains robust and compliant with analytics requirements. For example, in the picture below, extending to new columns that don't match the schema of the syslog table throws an error during validation and asks the user to send to a custom table or remove the transformations. While in the case of the example below, filtering does not modify the schema of the data at all and so no validation error is thrown, and the user is able to send it to a standard table directly. 2. Pre-built KQL templates Apply ready-to-use templates for common transformations. Save time and minimize errors when writing queries. 3. Automatic schema standardization for syslog and CEF Automatically schematize CEF and syslog data to fit standard tables without any added transformations to convert raw data to syslog/CEF from the user. 4. Advanced filtering Drop unwanted events based on attributes like: Syslog: Facility, ProcessName, SeverityLevel. CEF: DeviceVendor, DestinationPort. Reduce noise and optimize ingestion costs. 5. Aggregation for high-volume logs Group events by key fields (e.g., DestinationIP, DeviceVendor) into 1-minute intervals. Summarize high-frequency logs for actionable insights. 6. Drop unnecessary fields Remove redundant columns to streamline data and reduce storage overhead. Supported KQL sunctions 1. Aggregation summarize (by), sum, max, min, avg, count, bin 2. Filtering where, contains, has, in, and, or, equality (==, !=), comparison (>, >=, <, <=) 3. Schematization extend, project, project-away, project-rename, project-keep, iif, case, coalesce, parse_json 4. Variables for Expressions or Functions let 5. Other Functions String: strlen, replace_string, substring, strcat, strcat_delim, extract Conversion: tostring, toint, tobool, tofloat, tolong, toreal, todouble, todatetime, totimespan Get started today Head to the Azure Portal and explore the new Azure Monitor pipeline transformations UI. Apply templates, validate your KQL, and experience the power of Azure Monitor pipeline transformations.

Accelerating SCOM to Azure Monitor Migrations with Automated Analysis and ARM Template Generation
Accelerating SCOM to Azure Monitor Migrations with Automated Analysis and ARM Template Generation Azure Monitor has become the foundation for modern, cloud-scale monitoring on Azure. Built to handle massive volumes of telemetry across infrastructure, applications, and services, it provides a unified platform for metrics, logs, alerts, dashboards, and automation. As organizations continue to modernize their environments, Azure Monitor is increasingly the target state for enterprise monitoring strategies. With Azure Monitor increasingly becoming the destination platform, many organizations face a familiar challenge: migrating from System Center Operations Manager (SCOM). While both platforms serve the same fundamental purpose—keeping your infrastructure healthy and alerting you to problems—the migration path isn’t always straightforward. SCOM Management Packs contain years of accumulated monitoring logic: performance thresholds, event correlation rules, service discoveries, and custom scripts. Translating all of this into Azure Monitor’s paradigm of Log Analytics queries, alert rules, and Data Collection Rules can be a significant undertaking. To help with this challenge, members of the community have built and shared a tool that automates much of the analysis and artifact generation. The community-driven SCOM to Azure Monitor Migration Tool accepts Management Pack XML files and produces several outputs designed to accelerate migration planning and execution. The tool parses the Management Pack structure and identifies all monitors, rules, discoveries, and classes. Each component is analyzed for migration complexity: some translate directly to Azure Monitor equivalents, while others require custom implementation or may not have a direct equivalent. Results are organized into two clear categories: Auto-Migrated Components – Covered by the generated templates and ready for deployment Requires Manual Migration – Components that need custom implementation or review Instead of manually authoring Azure Resource Manager templates, the tool generates deployable infrastructure-as-code artifacts, including: Scheduled Query Alert rules mapped from SCOM monitors and rules Data Collection Rules for performance counters and Windows Events Custom Log DCRs for collecting script-generated log files Action Groups for notification routing Log Analytics workspace configuration (for new environments) For streamlined deployment, the tool offers a combined ARM template that deploys all resources in a single operation: Log Analytics workspace (create new or connect to an existing workspace) Action Groups with email notification All alert rules Data Collection Rules Monitoring Workbook One download, one deployment command — with configurable parameters for workspace settings, notification recipients, and custom log paths. The tool generates an Azure Monitor Workbook dashboard tailored to the Management Pack, including: Performance counter trends over time Event monitoring by severity with drill-down tables Service health overview (stopped services) Active alerts summary from Azure Resource Graph This provides immediate operational visibility once the monitoring configuration is deployed. Each migrated component includes the Kusto Query Language (KQL) equivalent of the original SCOM monitoring logic. These queries can be used as-is or refined to match environment-specific requirements. The workflow is designed to reduce the manual effort involved in migration planning: Export your Management Pack XML from SCOM Upload it to the tool Review the analysis — components are separated into auto-migrated and requires manual work Download the All-in-One ARM template (or individual templates) Customize parameters such as workspace name and action group recipients Deploy to your Azure subscription For a typical Management Pack, such as Windows Server Active Directory monitoring, you may see 120+ components that can be migrated directly, with an additional 15–20 components requiring manual review due to complex script logic or SCOM-specific functionality. The tool handles straightforward translations well: Performance threshold monitors become metric alerts or log-based alerts Windows Event collection rules become Data Collection Rule configurations Service monitors become scheduled query alerts against Heartbeat or Event tables Components that typically require manual attention: Complex PowerShell or VBScript probe actions Monitors that depend on SCOM-specific data sources Correlation rules spanning multiple data sources Custom workflows with proprietary logic The tool clearly identifies which category each component falls into, allowing teams to plan their migration effort with confidence. A Note on Validation This is a community tool, not an officially supported Microsoft product. Generated artifacts should always be reviewed and tested in a non-production environment before deployment. Every environment is different, and the tool makes reasonable assumptions that may require adjustment. Even so, starting with structured ARM templates and working KQL queries can significantly reduce time to deployment.
