Endpoint guardrails that discover every coding agent on a developer's machine and police what it is allowed to do
Legit Security VibeGuard secures AI coding agents at the developer endpoint, automatically discovering tools like Claude Code, Cursor and GitHub Copilot and applying real-time policy guardrails to the commands and MCP servers they invoke. It is built for application security teams whose developers have adopted agentic coding faster than security can review the resulting code and tool access.
Legit Security VibeGuard secures AI coding agents at the point where code is generated. The original release arrived in the fourth quarter of 2025 as an IDE-embedded product that scanned AI-generated code with SAST and SCA, blocked prompt injection, detected data leaks, restricted agent access to sensitive files and credentials such as .env, and gave security teams a centralised dashboard over which models and extensions were approved. VibeGuard 2.0, announced on 3 August 2026, is an architectural shift rather than an increment: it moves off the IDE extension model and runs directly on the developer endpoint, which lets it automatically discover every coding agent present — Claude Code, Cursor, GitHub Copilot and their plugin variations — instead of only those in a supported editor. Running at the endpoint also makes it substantially harder to remove or bypass, and version 2.0 adds explicit anti-tampering controls that stop agents disabling the tool and stop users circumventing protections. The new capabilities centre on skill discovery and protection, dangerous-operation blocking, and granular Model Context Protocol security, backed by command-level visibility into what agents actually execute and policy enforcement that can halt risky operations before they touch production or leak sensitive data. CTO and co-founder Liav Caspi frames the design goal as enhancing agents rather than blocking them, positioning developer experience as a first-order constraint. VibeGuard sits within Legit Security's broader AI-native application security posture management platform, whose customers include Netskope, Kraft Heinz, AIG, Freddie Mac, Cboe Global Markets and ZoomInfo.
The AppSec lead at an engineering organisation where developers have already adopted Claude Code, Cursor or Copilot faster than security can govern what those agents touch.
Automatic discovery of every coding agent on a developer machine, with tamper-resistant policy enforcement on the commands and MCP servers they invoke.

Key Features
- ✓Automatic coding agent discovery
Finds Claude Code, Cursor, GitHub Copilot and their plugin variations on the endpoint without relying on a supported IDE.
- ✓Endpoint-level enforcement
Runs on the developer machine rather than as an IDE extension, so coverage does not depend on which editor a developer picks.
- ✓Anti-tampering controls
Prevents agents from disabling the tool and stops users circumventing protections, closing the obvious bypass path.
- ✓Granular MCP security
Governs which Model Context Protocol servers and tools an agent may invoke, a fast-growing and largely ungoverned attack surface.
- ✓Dangerous operation blocking
Halts risky agent-executed commands using custom or built-in policies before they damage production or leak data.
- ✓Skill discovery and protection
Inventories and secures the skills an agent can load, so capabilities added after deployment do not escape policy.
- ✓Centralised AI governance dashboard
Gives security real-time visibility across all developer endpoints into which models, prompts and MCPs are in active use.
Capabilities
Use Cases
- •Containing shadow AI in engineering
Security discovers which coding agents developers actually installed, replacing a policy document with an accurate live inventory.
- •Preventing credential exfiltration by agents
Policies block agent reads of .env files and other secrets, a documented failure mode in real agent deployments.
- •Governing MCP server sprawl
Teams restrict agents to vetted MCP servers instead of letting each developer wire in arbitrary third-party tool endpoints.
- •Stopping destructive agent commands
Dangerous-operation blocking intercepts commands that would delete data or alter production, a class with public precedent.
- •Evidencing AI code governance to auditors
Endpoint telemetry shows which models generated code and which policies fired, supporting internal and external review.
Ideal For
Best For
- ✓Discovering shadow AI coding agents developers have installed without security approval
- ✓Blocking dangerous agent operations such as writes to production or reads of credential files
- ✓Governing which MCP servers and tools coding agents are permitted to call
- ✓Enforcing approved-model and approved-extension policy across a distributed engineering org
- ✓Preventing sensitive data leakage through agent prompts and generated code at the moment of creation
Not Ideal For
- ✗Teams that need a generally available, contractually supported product today — Security Boulevard notes Legit had not announced general commercial availability for the 2.0 release
- ✗Organisations unwilling to deploy an agent on developer endpoints, since the tamper resistance that makes 2.0 effective is exactly what makes it intrusive
- ✗Shops standardised on a single IDE with tight native controls, where the original IDE-extension approach or the vendor's built-in policies may suffice
- ✗Buyers wanting published pricing, as none is disclosed for VibeGuard in any tier
Deployment
Market Analysis
Pros
- ✓Endpoint architecture solves a real gap — IDE extensions cannot see agents running outside the editor, which is where Claude Code operates
- ✓MCP governance is genuinely ahead of most application security tooling, which still treats agents as code generators rather than tool callers
- ✓Backed by $77M and a credible enterprise customer base including Netskope, Kraft Heinz, AIG, Freddie Mac, Cboe Global Markets and ZoomInfo
- ✓Design philosophy explicitly prioritises developer experience over blocking, which is the usual reason such controls get uninstalled
Cons
- ✗Security Boulevard reports that Legit had not announced general commercial availability for VibeGuard 2.0 at launch, so buyers may be evaluating a pre-GA product
- ✗No pricing, metering model or tier structure is published anywhere, making cost comparison against Snyk or Cycode impossible without sales engagement
- ✗An endpoint agent on every developer machine with anti-tampering is a meaningful trust and performance ask, and developer resistance is the well-known failure mode for this category
- ✗No independent benchmarks, no G2 or Capterra ratings for VibeGuard specifically, and no Hacker News discussion of the product were found
- ✗Compliance certifications for VibeGuard were not stated on the pages reviewed, so SOC 2 and ISO status could not be confirmed
- ✗The most recent disclosed funding round is from September 2023, which is dated for a company launching in a fast-moving category
Pricing
Enterprise
Contact for pricing
- ✓VibeGuard endpoint agent
- ✓Policy enforcement and governance dashboard
- ✓Part of the Legit ASPM platform
No pricing is published for VibeGuard in any tier, and neither the vendor announcement nor the independent coverage from Help Net Security and Security Boulevard discloses a figure or a metering model. It is sold as part of Legit Security's enterprise ASPM platform through direct sales, so expect seat-based or developer-based negotiation; Security Boulevard additionally notes that general commercial availability for the 2.0 release had not been announced at launch.
