Vulert vs Black Duck

Vulert is a software composition analysis service that monitors an application open-source dependencies for known vulnerabilities without access to source code. Projects are added by uploading a manifest or lockfile, for example package-lock.json, yarn.lock, pom.xml, requirements.txt, go.sum, Cargo.lock, composer.lock or Gemfile.lock, or an SBOM in SPDX or CycloneDX format, which Vulert checks against its own vulnerability database. Alerts are delivered through the dashboard and email, with Jira, CI/CD, Slack or Discord and SIEM integrations listed among the platform features, and separately priced modules for Docker image scanning, open-source licence compliance and SBOM export. It is a hosted SaaS product requiring no agent, installation or repository connection, operated by Vulert LTD, a company registered in England.

Pros

• No source code access, agent or repository connection is required. The vendor states that only metadata such as SBOMs and manifests is analysed, which can suit teams whose code cannot leave the organisation.
• Pricing figures are published on the website rather than quote-only, starting at $20 per month, with a $0 evaluation tier and a stated 30-day free trial.
• The public scanner runs without signup, so detection output on a real manifest can be inspected before any purchase. The scanner page showed 493,778 vulnerabilities in the database, last updated 3 August 2026.

Things to check

Pricing: Trial $0 (1 user, up to 50 apps); Starter $20/month; Pro $45/month; Growth $125/month; Enterprises from $500/month. Annual billing lists $18, $39 and $110 for the three paid tiers. 30-day free trial stated.

Black Duck (a Synopsys product) is an enterprise-grade software composition analysis platform that provides deep visibility into open-source risks, license compliance, and code origin analysis. Black Duck's multi-factor open-source detection uses package managers, file-level analysis, and code snippet matching to identify open-source components even when they are not declared in manifests, making it the most thorough SCA tool for auditing software acquisitions, M&A due diligence, and regulatory compliance. Black Duck is part of Synopsys's broader application security portfolio alongside Coverity (SAST) and Polaris.

Pros

• Most thorough open-source detection including undeclared and embedded components
• Massive KnowledgeBase tracking 7M+ open-source components and versions
• Gold standard for M&A software due diligence and audit
• Comprehensive SBOM generation for supply chain transparency
• Part of Synopsys ecosystem with Coverity SAST and Polaris platform

Things to check

• Significantly more expensive than Snyk with enterprise-only pricing
• Developer experience is audit-oriented rather than developer-friendly
• Scan performance is slower due to deep multi-factor analysis
• Complex deployment and configuration for enterprise environments
• Less suited for real-time developer feedback in CI/CD pipelines
