Integration Overview

Envoy is an open source distributed proxy which can serve at the edge of an application or in a service mesh. Panther’s native SIEM integration enables you to quickly collect, normalize, and monitor Envoy logs, giving your security team complete visibility over events in your Envoy network. Your normalized data is then retained to power future security investigations in a serverless data lake powered by Snowflake.

Use Cases for Envoy Access Logs

Panther offers native support for Envoy proxy access logs, which capture the HTTP requests that flow through the proxy. Some common SIEM use cases for these logs include:

  • Real-time monitoring of suspicious requests
  • Identifying the source of network and application problems
  • Corroborating Envoy network events with other data sources

Onboarding Envoy Logs in Panther

Panther’s integration for Envoy is simple to configure, allowing you to stream your logs in just a few minutes. You’ll simply select Envoy from the list of log sources in the Panther console, and then create a Fluent Bit to forward your Envoy logs.

For more detailed steps on onboarding Envoy audit logs or for supported schema, you can view our Envoy documentation here.

Normalizing & Analyzing Envoy Logs

As Panther ingests Envoy logs, they are parsed, normalized, and stored in a Snowflake security data lake. This empowers security teams to craft detections, identify anomalies, and conduct investigations on your data in the context of days, weeks, or months.

Panther’s managed schema will apply normalization fields to your Envoy logs, which standardize names for attributes and empower users to correlate and investigate data across all log types. For more on searching log data in Panther, check out our documentation on Investigations & Search.

Detection as Code

With Panther, your team won’t be confined to restrictive detection rules or domain-specific query languages as seen in many SIEM platforms. Panther is built with detection-as-code principles, giving you the ability to write Python to define detection logic and to integrate external systems like version control and CI/CD pipelines into your detection engineering workflows. This results in powerful, flexible, and reusable scripting of detections for your security team.

Configuring Alerts

Panther triggers alerts when your detection rules or policies are matched, and integrates with a variety of alert destinations to allow for easy access and management of any Envoy alerts. Alerts can also be forwarded to alert context or SOAR platforms for more remediation options.

Alerts are categorized in five different severity levels: Info, Low, Medium, High, and Critical. Security teams have the options to dynamically assign severity based on specific log event attributes.

Customer Support

If you have any questions about configuring or monitoring Envoy logs in Panther, we’re here to help. All customers have access to our technical support team via a dedicated Slack channel, email, or in-app messenger.

You can view our documentation on configuring and monitoring Envoy logs here, or customers can sign up for the Panther Community to share best practices or custom detections for monitoring Envoy.

The Ideal SIEM Integration for Envoy

With Panther, security teams don’t have to struggle with restrictive detection logic, waste time and resources on operational overhead, or pay skyrocketing costs to keep up with the growth of their organization’s data. Panther was founded by a team of veteran security practitioners who struggled with legacy SIEM challenges first-hand, and built an intuitive, cloud-native platform to solve them.

Panther is a cloud SIEM built for security operations at scale, offering easy data ingestion, flexible detection-as-code, and intuitive alert and response workflows to keep up with the needs of today’s security teams.
