Best alternatives to SolonGate in 2026
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.
