• Very deep SAST analysis with wide language coverage including legacy enterprise languages.
• One platform and one risk view across every scan type.
• Strong compliance and audit reporting.

• Free, with no licence limits on scanning or users.
• The baseline scan runs in CI in a couple of minutes and catches real misconfiguration.
• Active community and extensive add-on marketplace.

• Expensive, with a long procurement and deployment cycle.
• High false-positive volume typical of deep SAST; tuning is a project.
• Scans are slow relative to developer-first tools.

• Higher false-positive rate than commercial DAST tools.
• Scanning authenticated, JavaScript-heavy applications requires meaningful configuration effort.
• The interface is dated and the learning curve is real.

Large enterprises with a security function and regulatory obligations.
