# Kong AI Gateway review

What Kong AI Gateway is, where it is strong, and where it falls short for securing AI agents and their tool calls. Every claim is drawn from Kong AI Gateway's own public material, listed in Sources.

Last updated: September 2026

## What Kong AI Gateway is

Kong AI Gateway is an enterprise API, LLM and MCP gateway: it turns APIs into MCP servers and secures, observes and governs MCP, LLM and A2A traffic through route-level plugins, with an MCP Registry for tool discovery.

## Where Kong AI Gateway is strong

- Runtime enforcement. Blocks a dangerous tool call before it executes, not just after the fact.
- DLP, PII and secrets scanning. Inspects tool inputs and outputs for sensitive data at runtime.
- Prompt injection and tool-poisoning defense. Detects and stops injection, tool poisoning and rug-pull attacks.
- Gateway holds the credential. The gateway issues the final call so the agent cannot bypass policy and retry.
- Provable per-call audit. A receipt for every call: agent, tool, policy version, result.
- SIEM integration and export. Streams audit events to Splunk, Sentinel and other SIEMs.
- SSO, SCIM and RBAC. Enterprise identity, group sync and role-based access.
- Self-host, on-prem or VPC. Run it in your own environment for data residency.

## Where Kong AI Gateway falls short

Measured against a runtime agent data firewall. These are the gaps that matter if your priority is stopping data loss at the point of the tool call.

- SealGate runs a device-level agent and discovers shadow MCP servers on the endpoint; Kong's MCP Registry is an opt-in catalog of approved servers, not active on-device discovery.
- SealGate governs the agent CLI as well as MCP; Kong governs MCP and LLM traffic that flows through the network gateway.
- SealGate keeps local stdio servers on the device through a tunnel; Kong is an HTTP proxy that fronts networked MCP servers.

## Kong AI Gateway vs SealGate, feature by feature

SealGate leads with the rows at the top, its clearest points of difference, then the parity rows every enterprise gateway is expected to cover.

| Capability | SealGate | Kong AI Gateway |
| --- | --- | --- |
| How local stdio MCP servers are handled. Whether your local MCP server stays on the device or is shipped elsewhere. | Tunnel in place (Yes) | HTTP proxy (No) |
| Local stdio servers stay on-device. The server keeps running on the machine, with no host-and-lift and no HTTP re-expose. | ✓ Yes | ✕ No |
| Device-level management. An endpoint agent that discovers and governs MCP activity on the device itself. | ✓ Yes | ✕ No |
| Interface coverage. Whether the gateway governs only the MCP protocol, or the agent CLI and LLM API too. | MCP + CLI (Yes) | MCP + LLM/API (Partial) |
| Runtime enforcement. Blocks a dangerous tool call before it executes, not just after the fact. | ✓ Yes | ✓ Yes |
| DLP, PII and secrets scanning. Inspects tool inputs and outputs for sensitive data at runtime. | ✓ Yes | ✓ Yes |
| Prompt injection and tool-poisoning defense. Detects and stops injection, tool poisoning and rug-pull attacks. | ✓ Yes | ✓ Yes |
| Gateway holds the credential. The gateway issues the final call so the agent cannot bypass policy and retry. | ✓ Yes | ✓ Yes |
| Shadow MCP discovery. Finds unauthorized MCP servers before they are used. | ✓ Yes | ~ Partial |
| Provable per-call audit. A receipt for every call: agent, tool, policy version, result. | ✓ Yes | ✓ Yes |
| SIEM integration and export. Streams audit events to Splunk, Sentinel and other SIEMs. | ✓ Yes | ✓ Yes |
| SSO, SCIM and RBAC. Enterprise identity, group sync and role-based access. | ✓ Yes | ✓ Yes |
| Tool-level policy. Read and write tiers, per-tool rules and human-in-the-loop approvals. | ✓ Yes | ~ Partial |
| Self-host, on-prem or VPC. Run it in your own environment for data residency. | ✓ Yes | ✓ Yes |
| Compliance mapping. Evidence mapped to SOC 2, NIST AI RMF and the EU AI Act. | ~ Partial | ~ Partial |
| Low latency overhead. Minimal added latency on the tool-call path. | ✓ Yes | ~ Partial |
| Open source core. An open, inspectable core rather than a closed proxy. | ✕ No | ~ Partial |

Bottom line: Kong is an enterprise gateway that governs MCP and LLM traffic at the network route level; SealGate is a device-level firewall that keeps local servers on the endpoint, discovers shadow MCP, and governs the agent CLI.

## Frequently asked questions

What is Kong AI Gateway? Kong AI Gateway is an enterprise API, LLM and MCP gateway: it turns APIs into MCP servers and secures, observes and governs MCP, LLM and A2A traffic through route-level plugins, with an MCP Registry for tool discovery.

What are the main limitations of Kong AI Gateway? The clearest gap for teams focused on runtime data security: SealGate runs a device-level agent and discovers shadow MCP servers on the endpoint; Kong's MCP Registry is an opt-in catalog of approved servers, not active on-device discovery. Weigh this against your own priorities before deciding.

Is Kong AI Gateway worth it? It depends on the axis you care about. Kong is an enterprise gateway that governs MCP and LLM traffic at the network route level; SealGate is a device-level firewall that keeps local servers on the endpoint, discovers shadow MCP, and governs the agent CLI. Compare the two on the capabilities that matter to you.
