The Silverfort plugin for Microsoft Copilot for Security enables seamless integration of Silverfort's advanced CEF data within the Microsoft Sentinel environment to bring in Identity protection insights. This plugin empowers security teams to enhance their threat detection and response capabilities through intuitive natural language queries and detailed insights.
The Silverfort plugin leverages KQL-based queries to extract and analyze data from Silverfort's security logs within the Microsoft Sentinel workspace. Users can customize their queries using a range of input parameters to retrieve targeted information, enabling more efficient threat investigation and proactive defense measures.

Prerequisites
To use the Silverfort plugin you must first configure Common Event Format (CEF) and Syslog through Azure Monitor Agent (AMA) forwarding using the following guide. This plugin queries data stored in the CommonSecurityLog table in a log Analytics workspace enabled for Microsoft Sentinel. For more information, see Ingest syslog and CEF messages to Microsoft Sentinel with the Azure Monitor Agent.
After setting up a forwarder, proceed to:
- Assign a public IP address
- Allow Syslog inbound traffic on port 514 in network settings
You're now ready to set up your Syslog Server in Silverfort to send the events and have the newly configured AMA forward the information to Microsoft Sentinel.
Enter the IP Address of your AMA Forwarder in the Server IP field.
Enter port 514 in the Port field.
Select TCP Protocol in the Protocol Field.
Verify that all the information in the fields are present except the Splunk application.
Select Save All.

Troubleshoot the Silverfort plugin
Errors occur
If you encounter errors, such as Couldn't complete your request, or An unknown error occurred | Make sure the plugin is turned on. This error may occur if the lookback period is too long, causing the query to attempt to retrieve an excessive amount of data. If the issue persists, sign out of Copilot for Security, and then sign back in.
Prompts aren't invoking the correct capabilities
If prompts aren't invoking the correct capabilities, or prompts are invoking some other capability set, you might have custom plugins or other plugins that have similar functionality as the capability set you want to use.
