SolonGate

About SolonGate

SolonGate is a zero-trust security gateway that controls what autonomous AI agents are allowed to do when they interact with internal systems. It sits between a large language model and APIs or databases, intercepting each attempted action and blocking any that violate policies before execution. The tool shifts focus from filtering text prompts to governing the actual operations agents carry out.

Review

SolonGate enters a space where many security layers still cling to prompt-level inspection, which the makers themselves discarded as broken for autonomous agents. The gateway now functions purely as an action governance layer-it doesn't police language, it blocks risky API calls, database queries, and similar operations in real time. The approach aligns with a zero-trust model, treating every agent action like untrusted traffic that must earn passage.

Key Features

• Deterministic Policy Engine. Rules-based filtering inspects each action against predefined authorization, rule, and risk layers before it can touch backend systems.
• Isolated AI Judge. A localized judging component evaluates the risk profile of actions that aren't hard-blocked by policy, adding a second screening step without relying on external model providers.
• Structured denial responses. When an action is blocked, SolonGate returns a JSON payload naming the layer that triggered the denial (Authorization, Rule, or Risk) and a plain-language reason, making the decision auditable in agent traces or observability stacks.
• Inline interception. The gateway sits directly in the communication path between LLMs and internal APIs, so no action reaches production databases or services without passing through both the Policy Engine and AI Judge.
• Free launch access. The product launched with free options available, though long-term pricing tiers are not yet specified.

Pricing and Value

SolonGate's Product Hunt listing includes a "Free Options" tag, indicating a free tier exists at launch. Beyond that, pricing details are not yet defined on the product page or in the launch materials. Teams evaluating it should test the free tier and watch for the makers' roadmap announcements to understand future cost structures.

Pros

• Focuses on action execution rather than prompt text, addressing a gap that appears when agents have real API write permissions.
• Returns machine-readable denial reasons that integrate with existing logging and monitoring tooling.
• Combines deterministic rules with an AI-based judge that runs locally, reducing dependency on cloud-only filtering.
• The small, engineering-led team rebuilt the product quickly after recognizing their earlier text-filtering approach fell short.
• Zero-trust posture means agents are treated as untrusted actors even when operating inside a company's own infrastructure.

Cons

• It's not well suited for teams that only deploy read-only chatbots or agents without execution capabilities-there's little to govern if no destructive actions can be taken.
• As a newly launched tool from a two-person team, long-term support, documentation depth, and integration coverage are yet to be proven.
• The isolated AI Judge's accuracy on subtle edge cases hasn't been benchmarked publicly, and closed-source components limit independent security review.

SolonGate fits engineering teams that already give AI agents access to production APIs, databases, or internal services and need a hard enforcement point before execution happens. It's a narrow, purpose-built layer for those who have moved past simple chatbots and into agentic workflows where a bad action isn't just a wrong answer-it's a deleted table or an unauthorized refund event.
