Network Security Agent: Troubleshoot App-ID

Diagnose application access failures caused by App-ID classification issues using the Troubleshooting agent in Strata Copilot.
Where Can I Use This?What Do I Need?
  • Strata Cloud Manager
  • Strata Cloud Manager Pro
  • This feature is currently in Beta and available on request. Contact your account team to enable the feature.
  • Superuser role (for agent administration, onboarding, and managing permissions)
  • Network Administrator or Security Administrator role (for agent interaction)
The Troubleshooting agent automates the diagnosis of application access failures caused by App-ID classification issues. This workflow reduces the time to identify App-ID-related access failures from hours of manual log correlation to minutes of automated analysis.
The agent executes the following diagnostic stages:
  • Symptom intake—Gathers the affected user, application, location, timeframe, and symptom scope (single user vs. multiple users) to establish the investigation parameters.
  • Classification analysis—Determines how the target traffic is currently being classified by App-ID and identifies the cause of any classification discrepancy, such as a content update that modified an App-ID, a custom App-ID conflict, or an application dependency issue.
  • Policy impact analysis—Correlates the App-ID classification with your security policy rules to identify which rule is now matching (or not matching) the traffic, and determines whether the resulting action aligns with your security intent.
  • Root cause and remediation—Synthesizes findings into a root cause determination (by-design block vs. misconfiguration), provides specific remediation steps with blast radius assessment, and includes verification steps to confirm the fix.

Investigate an App-ID Classification Issue

Use the Troubleshooting agent to diagnose why users lost access to an application due to an App-ID classification issue.
  1. Open Strata Copilot in Strata Cloud Manager.
  2. Select Troubleshooting from the @Agent drop-down.
  3. Describe the App-ID classification issue. Mention App-ID or classification changes in your query so the agent investigates the correct failure domain. For example:
    • "Traffic to our SaaS app is now classified as a different App-ID than it was yesterday"
    • "After the last content update, our CRM application is being blocked—I think the App-ID changed"
    • "File uploads in our project management tool stopped working and the traffic logs show a new App-ID I haven't seen before"
  4. (Optional) Provide additional input if prompted. If your query does not include enough detail, the agent presents an Activity Plan and prompts you to provide more information before generating an investigation plan. Enter the requested details and click Submit.
  5. Review the plan the agent presents. The agent analyzes your query and generates an investigation plan tailored to the reported issue. Click Execute to proceed with the plan, or click Modify to refine it before execution.
  6. Provide additional details if prompted. Depending on the information available, the agent may present a clarification form requesting details such as the affected application or destination, the observed classification change, and the impact on traffic. Provide as much detail as you can—the agent uses your responses to narrow the investigation scope.
  7. Review the execution results. After the investigation completes, the agent presents an Execution Summary that includes:
    • The root cause of the classification issue (content update, custom App-ID conflict, dependency issue, or other cause) and the specific App-ID change that affected your traffic.
    • Whether the block is by-design (policy is correctly enforcing the classification) or a misconfiguration (policy needs updating to reflect the correct App-ID).
    • Recommended remediation steps, such as adding a new App-ID to an existing allow rule or creating an application filter.

App-ID Troubleshooting Scenarios

The following scenarios illustrate how you can use the Troubleshooting agent to diagnose and resolve application access failures caused by App-ID classification issues.
Scenario 1: App-ID Merge Breaks an Allow Rule
  • Scenario: Multiple users report they can no longer access an internal collaboration platform. The issue started after a content update installed overnight.
  • Query: "The entire product team lost access to our internal wiki this morning—it was working fine yesterday"
  • Agent Finding: Content update 8891 merged App-ID custom-wiki-app into the broader enterprise-wiki App-ID. The security policy rule "Allow-Product-Tools" references custom-wiki-app, which no longer matches the reclassified traffic. The traffic now hits the interzone-default deny rule.
  • Remediation: Add enterprise-wiki to the "Allow-Product-Tools" rule, or replace the specific App-ID reference with an application filter that covers collaboration tools. Blast radius: other enterprise wiki applications will also match this rule.
Scenario 2: New App-ID Captures Previously Allowed Traffic
  • Scenario: A user reports that file sharing within a SaaS application stopped working, though the main application interface still loads.
  • Query: "User jdoe can log into our project management tool but file uploads and downloads are blocked since Tuesday"
  • Agent Finding: Content update 8893 introduced a new App-ID projectmgmt-file-transfer that captures file operations previously classified under the parent App-ID projectmgmt-base. The policy allows projectmgmt-base but does not include the new projectmgmt-file-transfer App-ID.
  • Remediation: Add projectmgmt-file-transfer to the allow rule, or use an application filter based on the project-management application category to automatically capture future sub-app additions. Blast radius: minimal—only the specific file-transfer function is affected.
