Beam vs VibeGuard 2.0

Legit VibeGuard 2.0 folds agent monitoring, skill discovery, MCP checks and blocking into Legit Security's application security platform, aimed at Fortune 500 rollouts. It has enforcement that Beam does not. Beam is a standalone, local-first prototype with pre-run scanning and no platform to adopt around it.

Where VibeGuard 2.0 does more

  • Blocking is available now, not on a roadmap.
  • Skill discovery and MCP security are first-class parts of the product, already at v2 as of August 3, 2026.
  • Backed by an established application security vendor with existing enterprise relationships.

Where Beam differs

  • Beam is a single-purpose agent monitor rather than a module inside a broader AppSec platform, so there is nothing else to adopt.
  • Beam's scan runs locally on a file you point it at, before you run it.
  • Beam keeps its data on the machine that produced it, with credentials redacted before writing.

Beam’s current gaps

  • Beam observes and flags. It has no blocking or enforcement, so it cannot stop a destructive command.
  • There is no MDM package, central console, SSO or SOC 2 report, so it is not ready for a managed fleet rollout.
  • Scanning is heuristic pattern matching. It produces false positives, misses novel phrasing, and is not a guarantee of safety.
  • Beam is early and has no published pricing. Every tool on this page is further along in at least one dimension.

Which one fits

If you are already a Legit Security customer or want agent security inside your AppSec platform, VibeGuard is the natural fit and ships enforcement today. Beam fits a smaller question: what is the agent on this machine doing, and is this skill safe to run.
