Security Engineer Experience

This page outlines how Security Engineers can use the StepSecurity platform to strengthen CI/CD security, monitor supply chain risk, and respond effectively to runtime threats in GitHub Actions environments.

Security Engineers typically rely on StepSecurity for four key workflows:

• Integrating CI/CD telemetry into existing security operations

• Reviewing third-party GitHub Actions for compromise risk

• Searching packages for known malicious activity

• Responding to Harden-Runner detections and workflow failures

Integration with SIEM

StepSecurity supports integrations with external platforms to enhance your security workflows, automate telemetry export, and streamline policy enforcement.

We currently support the following third party integrations:

• S3 Integration: Export Harden-Runner insights and detections to S3

• Webhook Integration: Send event data to SIEM platforms or custom pipelines

• Slack OAuth Integration: Receive detection alerts and respond faster

• Terraform Provider: Manage policies and integrations through infrastructure-as-code

Third Party Actions Review

Third-party GitHub Actions are one of the most common entry points for CI/CD supply chain attacks.

StepSecurity makes it easy to review and stay up to date with all third-party actions across your organization.

Explore the interactive demo to see how StepSecurity helps you continuously assess third-party action risk:

NPM Package Search

The NPM Package Search feature helps Security Engineers quickly identify where specific npm packages were introduced across pull requests in their organization.

This is especially useful when responding to compromised or vulnerable dependencies, allowing teams to:

• Trace affected pull requests

• Understand the potential blast radius across repositories

• Take targeted remediation actions

StepSecurity supports searches across the Node.js ecosystem, including npm, yarn, and pnpm dependency files.

Responding to Harden-Runner Detections

CI/CD runners handle sensitive secrets and production builds, but often lack the monitoring coverage of traditional endpoints. Harden-Runner fills this gap by providing runtime security tailored for GitHub Actions workflows.

When a detection is triggered, Security Engineers can use StepSecurity to:

• Review the detection context and severity

• Identify affected workflows, repositories, and outbound activity

• Investigate suspicious behavior such as secret exfiltration, anomalous network calls, or source code tampering

• Apply recommended policies and enforcement to prevent recurrence

Harden-Runner has detected real-world CI/CD supply chain attacks in real time, enabling faster response and reduced blast radius.

Investigating Check Failures (GitHub Checks)

StepSecurity’s GitHub Checks feature brings CI/CD security signals directly into the pull request workflow, helping Security Engineers enforce controls before risky changes are merged.

These checks make it easy to:

• Understand why a workflow or dependency change was blocked

• Surface Harden-Runner detections and supply chain risks inside GitHub

• Enforce security guardrails through required or optional merge checks

When a check fails, Security Engineers can quickly review the findings, validate whether the behavior is expected, and approve or remediate as needed.

This ensures security-driven failures are actionable, auditable, and integrated into the developer workflow.
