Editorial, research-based; no lab testing or paid placement.
Research-based: pipeline-discovery depth, integrity/tamper detection, hardening capability, native-control coverage, pricing transparency, acquisition clarity.
No lab claims; no vendor influence. Priority: native-first honesty price what your CI already includes before dedicated spend.

Activate native controls first (GHAS/GitLab tiers reset the case), harden the execution layer (StepSecurity-class egress/pinning the actual attack surface), then buy posture (Cycode/Legit) where estate sprawl demands discovery.
Watch behavior (Arnica) where insider/dev-account risk matters; operationalize SLSA (Kusari) as contracts demand evidence.
Common mistakes: dedicated spend before native activation; secrets scanned while runners egress freely; evaluating static application security testing (SAST) without considering runner context; attestations treated as slideware.
Native baselines first (GitHub Advanced Security, GitLab Ultimate), Cycode and Legit for dedicated posture, StepSecurity for runner/action hardening, Arnica for behavioral detection, Kusari for SLSA plumbing with Argon (Aqua) and Cider (Palo Alto) serving their platforms.
Published per-committer/tiers natively; free-plus-tiers for hardening (StepSecurity) and published tiers (Arnica); quotes across dedicated and absorbed lanes.
Poisoned pipelines, malicious actions/dependencies executing in CI, runner exfiltration, tampered builds, and stolen OIDC/cloud credentials the tradecraft behind modern supply-chain incidents. Coupling pipeline checks with container image scanning ensures malicious base layers don’t bypass execution guards.
Acquired Argon into Aqua (2021), Cider into Palo Alto (2023); both sell inside their platforms now. Evaluate under current packaging.
Push protection and action pinning this week; egress control on runners (Harden-Runner-class) next; pipeline discovery when you can’t name every workflow that can reach production which is most estates.
Native controls set the floor, StepSecurity guards the layer attackers actually use, and Cycode/Legit map the factory you’ve sprawled activate, harden, then discover.
Engaging top-tier penetration testing companies ensures build pipeline controls are rigorously audited against live exploit techniques.
Next step: pin your actions and filter runner egress before the next typosquatted dependency phones home.
