Harness Container Scanner

Scan container images with Harness Container Scanner

Harness Container scanner integrates directly within your CI/CD pipelines to scan container images to find vulnerabilities in OS packages and libraries installed in the image - without requiring external scanners or connectors.

With one-click configuration, Harness automatically manages authentication and licensing, while providing built-in data flow visualization, reachability analysis to determine whether a vulnerability is exploitable, and AI-powered remediation to help developers quickly understand and fix issues.

The Harness Container step works natively within STO, with all findings unified and visible alongside results from other security scanners.

Licensing

Running the Harness Container step in STO pipelines requires both Harness SAST and Harness SCA licenses.

For licensing details or to enable the Enterprise license, contact Harness Sales.

Free Trial

A 45-day free trial is available. If you are an existing Harness STO customer and want to access the Harness scanners, contact the Harness sales representative to have them enabled for your account.

Harness Container step settings for STO scans

To view Reachability information in Harness Container, you must run the Harness Code scanner. The scanner uses SAST based data flow analysis to understand how data moves through your code and determine whether an issue is reachable.

Setting up the Harness Container scanner is the same as configuring any other built-in scanner step. The required configuration for the scanner step is handled automatically, making the setup process simple and straightforward. Here’s how to set it up:

• In your Build or Security stage, open the step palette by clicking the Add Step option in your pipeline.

• Navigate to the Harness Security Scanners section under the Security Tests category. Select the Harness Container step.

• Provide the container information from which you want to pull your container images.

• By default, all the below fields are configured automatically by the Harness Container scanner.

  • Set the Scan Mode to Orchestration.

  • Set the Scan Configuration to Default

  • Set the Target Type to Container Image.

To run the Harness Container scan step in the pipeline, no further configuration is required; If you want to add additional scan settings, you can configure the following below fields in the step.

Target

Type

Target and Variant Detection

Name

Variant

Workspace

This field is visible only when you select Repository as the Target Type.

Use this field to specify an individual folder or file to scan. For example, if you want to scan a specific file like /tmp/example/test.py, set the workspace path to: /harness/tmp/example/test.py

• The Harness Container scanner is not supported in SMP.

• With a Harness Container Enterprise license, you also get access to the Qwiet AI by Harness platform. AppSec users can log in to the platform.

• The Qwiet AI dashboard does not support exemptions, so any issues you mark as exempt in Harness STO will not appear as exempted in Qwiet AI. Exemptions must be managed in Harness STO only.

View Harness Container Scan results in the Vulnerabilities tab

After you complete the pipeline run with the Harness Container scanner, in the vulnerabilities tab, apply the Issue Type filter as SCA to view the vulnerabilities identified by the Harness Container scanner.

Static Reachability

A vulnerability is considered as Reachable when an attacker can reach the affected code (CVE) through a controlled path from application input. A vulnerability is marked as Reachable if at least one of its occurrences is reachable. Exempted occurrences are not considered. You can view the Reachability for each of the occurrences of a security issue in the Vulnerabilities and Issues page.

After a successful pipeline run, the Vulnerabilities tab shows whether a vulnerability is marked as Reachable. On the Vulnerabilities page, use the Reachability filter to view findings by reachability. This helps reduce noise and focus on vulnerabilities that pose real risk. Learn more.

IDE Integration

Harness provides a code extension that helps you shift security even further left by allowing you to identify and fix vulnerabilities as you write code. It integrates directly into the developer workflow through IDE plugins for VS Code and JetBrains, with support for AI-native IDEs such as Cursor and Windsurf coming soon.

Harness also provides a CLI to run SAST and SCA scans locally, to help you identify code vulnerabilities and dependency risks before pushing code to your repository. Learn more on how to install, authenticate, and use the CLI commands in the Harness CLI.

AI remediation for Harness Container Security Issues

Harness AI analyzes security issues and provides AI remediation within the security details for each specific issue. This includes an analysis of the issue, remediation concepts, and step-by-step instructions to fix them. Additionally, for Container issues, Harness AI recommends safer package versions for upgrade, with remediation details available for each occurrence of an issue.

Enforce OPA Policy to block the Static Reachable Vulnerabilities

Enforce OPA Policy to automatically warn or block pipelines based on static reachability, exploitability, and license metadata, to help you prevent risky deployments and maintain security and compliance.

View Harness Container Scan results in the Qwiet AI Dashboard

After you complete the pipeline run with the Harness Container scanner, in the scan logs, you can click the provided shiftleftlink, which redirects you to the Qwiet AI dashboard, where you can explore detailed scan results and analyze identified issues.

You can also find the Qwiet AI dashboard URL in the pipeline Output tab. Look for the SCANNER_CONSOLE_URL output variable, which contains the direct link to your scan results in the Qwiet AI dashboard.

Alternatively, you can manually log in to the Qwiet AI by Harness dashboard and search for the application name that corresponds to the target name used in the scan.

You can view the generated SBOM for container image dependencies, along with the scan summary and compliance results, in the Qwiet AI by Harness dashboard. These details are currently available only in Qwiet AI by Harness dashboard and are not currently supported in Harness STO.

License Usage

Usage is calculated based on Active Developers. An Active Developer is an individual who, within the last 90 days, has created or modified code, configurations, content, or artifacts that are scanned by STO. An individual is counted only once, even if they contribute to multiple scanned repositories.

You can view your current usage and subscription details on the STO subscription page under the Harness Code and Container sub-tab
