• Proof-based scanning eliminates most false-positive triage, which is the main cost of DAST.
• Handles authenticated scanning of modern JavaScript applications well.
• Good asset discovery for organisations that do not know all their own sites.

• Custom rules are genuinely writable — you can encode your own security or architecture standards in an afternoon.
• Free CLI with a large community rule registry is immediately useful.
• Fast enough to run on every pull request without complaint.

• Expensive relative to free DAST alternatives.
• Scans take time and are not suited to per-commit feedback.
• Dynamic testing alone cannot find everything a code review would.

• Pattern matching without full dataflow misses some vulnerability classes.
• Community rule quality is uneven; expect to curate.
• Advanced dataflow and supply-chain features are paid only.

Organisations with many web applications and no capacity to triage scanner noise.

Teams that want customisable static analysis and can start entirely for free.
