Delta Scan

Automatically detect changes from your previous scan for continuous review. Pro

Overview

Delta Scan compares your current analysis results with the previous scan and detects the following changes:

• Added dependencies — newly added packages
• Removed dependencies — packages that were removed
• New vulnerabilities — newly detected vulnerabilities
• Resolved vulnerabilities — vulnerabilities fixed by version updates
• License changes — packages whose license classification changed
• Policy changes — changes in the overall policy evaluation
• AI Governance delta — AI component additions, removals, or changes (v2.0)

How to Use

1. Ensure your Pro license is active.
2. Run a scan as usual.
3. The first scan saves a snapshot and shows "First scan".
4. Subsequent scans automatically display differences from the previous scan.

Delta Details

When changes are detected, the Delta Details table shows:

• Change Type — Added / Removed / VulnerabilityNew / VulnerabilityResolved / LicenseChanged / PolicyChanged / AiGovernanceChanged
• Ecosystem — Python / Node.js
• Package Name
• Version
• Details — Severity, Advisory ID, license change details, AI component change details

Multi-Ecosystem Support

Delta comparison is performed independently per ecosystem. Same-named packages in Python and npm are tracked separately.
