SolonGate
A security checkpoint that sits between AI agents and the tools they're allowed to use, blocking dangerous actions before they run.

Description
When companies let AI agents — like automated coding assistants or customer-service bots — actually take actions such as calling APIs, touching databases, or running commands, someone has to make sure the agent doesn't do something it shouldn't, whether by mistake or because it was tricked. SolonGate sits as a checkpoint between the AI and the tools it's trying to use, checking every request against a rulebook before letting it through, the same way a bouncer checks IDs before letting someone into a venue.
SolonGate is a zero-trust security gateway built specifically for the Model Context Protocol (MCP), the emerging standard AI agents use to call external tools. It intercepts every tool call an agent makes, validates it against configurable security policies, and blocks or allows execution before the agent can touch internal systems, APIs, or databases. It's aimed at organizations — government, defense, large enterprises — deploying autonomous AI agents that need a server-side control point rather than trusting the agent's own guardrails. Pricing isn't public; SolonGate sells to enterprise/government buyers through direct contact.
💬 Our review
The short version: if you're letting AI agents execute real actions in production — not just answer questions — and you have zero visibility into what tools they're calling, SolonGate is a control point that can stop a bad or hijacked agent before it does damage.
SolonGate enters a fast-forming and already crowded field — Lasso Security, Onyx Security, and a wave of other 2025-2026 "AI agent security" startups are chasing the same problem from slightly different angles (runtime enforcement, identity governance, prompt-injection detection). SolonGate's specific niche is the MCP proxy layer itself: rather than watching agent behavior after the fact, it sits in the request path and can outright block a tool call. That's a meaningful architectural difference for security teams who want prevention, not just detection — but it also means SolonGate has to keep pace with every new MCP feature and integration, and a proxy that's too aggressive can break legitimate agent workflows. With no public pricing and an enterprise/government-only sales motion, this isn't a tool an individual developer or small startup can self-serve into; expect a sales conversation and a POC before you see a number.

📊 Global score
🤖 AI-enriched data
Pas de tarification publique ; contact commercial requis, orienté clients entreprise/gouvernement
Pros
Se positionne directement dans le chemin d'exécution (proxy MCP), donc peut bloquer un appel avant qu'il ne s'exécute, pas juste après coup
Conçu spécifiquement pour le protocole MCP, standard émergent des agents IA
Cible les déploiements les plus sensibles (gouvernement, défense)
Cons
Tarification totalement opaque
Marché ultra jeune et très concurrentiel (Lasso, Onyx, a16y et d'autres sur le même créneau)
Un proxy trop strict peut casser des workflows d'agents légitimes
Pas d'auto-service, cycle de vente entreprise obligatoire
