The short version

  • Only Chainguard has a free tier, so it costs nothing to try first.
  • Each has a real cost: Chainguard containers Catalog at 19,000 USD/year expensive for teams under 10 people; Fenergo implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.
  • They diverge on capability: Chainguard covers Hardened container images, Fenergo covers Regulatory rules library.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

Fenergo

  • Implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.
  • It orchestrates screening but does not supply the sanctions, PEP or adverse media data, so you still buy Dow Jones, LexisNexis or World-Check separately and those fees are per screened entity.
  • The entry price is set for institutions with large onboarding volumes, which puts it out of reach of smaller banks and fintechs that would otherwise benefit from the rules library.
  • Configuration is deep and specific, which makes upgrades between major versions a project rather than a patch, and some customers stay on old releases for years.
  • The rules library covers regulatory requirements, not your internal risk appetite, so the policy tuning that determines whether onboarding actually gets faster remains your work.

Answered from the vendors’ own pages

Chainguard: How much is the Chainguard Containers Catalog?

The Containers Catalog is 19,000 USD per year for 10-person engineering teams, providing access to 2,000+ hardened container images.

Source
Fenergo: Does Fenergo do the sanctions screening itself?

No. It orchestrates calls to third-party data providers such as Dow Jones and World-Check, and those subscriptions are additional and usually charged per screened entity.

Chainguard: What SLAs does Chainguard offer?

Chainguard provides contractual CVE remediation SLAs: 7 days for critical vulnerabilities, 14 days for high/medium/low severity, all with priority support.

Source
Fenergo: Is it SaaS or on-premises?

Both. The SaaS offering runs on Microsoft Azure with regional deployment options, which matters where data residency rules prohibit client data leaving the jurisdiction.

Chainguard: Can I try Chainguard before purchasing?

Yes. The free tier includes five container images for testing and deployment, allowing hands-on evaluation.

Source
Fenergo: How long does a deployment take?

Plan for a year at minimum for a multi-jurisdiction rollout. Single-jurisdiction deployments with a narrow product set can be shorter but rarely under six months.
