The short version

  • Only Atlantis has a free tier, so it costs nothing to try first.
  • Each has a real cost: Atlantis there is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.; Cybereason Defense Platform no published pricing on any platform tier: three plan levels (Enterprise, Enterprise Advanced, Enterprise Complete) feature-differentiated but cost-free
  • They diverge on capability: Atlantis covers Pull request plans, Cybereason Defense Platform covers Next-gen antivirus.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Atlantis

  • There is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.
  • The security surface is inherently sharp, because it is an internet-reachable webhook endpoint that executes applies with privileged credentials, gated by pull request comment authorisation that is coarse next to a real policy engine.
  • It is stateful, holding a working directory and lock database on local disk, so high availability and horizontal scaling are awkward and you own upgrades, webhook plumbing, secret rotation and the host itself.
  • It lacks the features that distinguish the commercial alternatives, with no native drift detection, no cost estimation, no managed state interface and no policy engine beyond the Conftest integration.
  • Terragrunt and monorepo layouts are not first-class, requiring hand-written custom workflows and repository configuration that becomes a growing maintenance burden as the number of repositories increases.

Cybereason Defense Platform

  • No published pricing on any platform tier: three plan levels (Enterprise, Enterprise Advanced, Enterprise Complete) feature-differentiated but cost-free
  • MDR services cost hidden: tiered MDR inclusion (Essentials, Essentials+XR, Complete) does not disclose pricing per tier
  • Add-on pricing absent: incident response, DFIR, assessments, mobile defense, threat hunting marked as 'Add-On' with no pricing
  • Sales-gated all pricing: no budget range or starting price available; customers must book demo or contact sales
