Legit Security is a platform that secures software development pipelines by detecting and preventing supply chain attacks across code, build, and deployment stages.

Legit Security is a commercial application security posture managementapplication security posture managementApplication security posture management, combining findings about applications from multiple tools and relating them to business context.

Compromising one part can affect the products or organizations that rely on it., including, through its VibeGuard capability, the AI agents, models, MCPMCPModel Context Protocol, a standard for connecting AI applications to external tools and data sources. A compatible server exposes capabilities an assistant can use through a common interface. servers, and skills running on developer endpoints. It runs as an agent on developer machines feeding into a central management layer, and is aimed at security teams responsible for CI/CD and supply-chain risk rather than at individual developers, though it surfaces sensitive or destructive agent actions — deleting code, altering database data, touching production systems — to developers directly for human review before execution. This lets security teams set organizational policy over which AI agents and models are permitted in development, sitting at the intersection of ASPMASPMApplication security posture management, combining findings about applications from multiple tools and relating them to business context. It helps teams decide which fixes matter most., secrets detection, and the newer problem of agentic development tooling. The company shipped its latest release, VibeGuard 2.0, 16 days ago, suggesting active development.

Legit Security publishes no documentation we track, so the description above is written from general knowledge rather than the vendor's own words.
How Legit Security helps
Which AI agents, models, MCP servers, and skills are actually running on developer machines right now?
an agent on each endpoint discovers and inventories what's installed and active in the agentic environment, feeding a central view security teams can check against what's actually permitted
Which agents are running that nobody in security ever approved?
compares the discovered inventory against organizational policy and flags agents, skills, and models operating outside what's been sanctioned
Is an agent about to delete code, alter database data, or touch a production system before it happens?
flags the action at runtime and surfaces it to the developer for human review before execution, rather than logging it after the fact
Who let a given AI model or MCP server onto a developer machine, and when?
the endpoint inventory ties each discovered agent, model, or skill to the machine it was found on, giving security teams a record to check enforcement against
Does a new package or dependency pulled into a project carry a known flaw or an exposed secret?
sits across the software supply chain, correlating dependency and secrets data with the same posture-management layer used for agent governance
Are the same permitted-agent rules being enforced consistently across every developer's machine?
the central management layer aggregates what each endpoint agent reports, so a machine running an unsanctioned or outdated policy set shows up against the rest

Five scores for Legit Security, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.
Score cards are part of every paid plan.

Blank means never measured; nothing here is a filled-in zero.
Peer standings are included with Researcher and Business. See how this tool ranks against its competitors, using data we don't publish anywhere else.
See plans →Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.
How this is scored
- Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
- Documentation quality — the release-notes rubric published on the analytics page, unchanged.
- Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
- Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
- Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
- Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
- Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
- Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.
