# TrueFoundry review

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

Last updated: September 2026

## What TrueFoundry is

TrueFoundry is a commercial enterprise AI and MCP gateway that centralizes inbound auth, RBAC, credential vaulting, runtime guardrails and observability across LLM and MCP traffic, deployable in your own cloud and certified SOC 2 Type II and HIPAA.

## Where TrueFoundry 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.
- Compliance mapping. Evidence mapped to SOC 2, NIST AI RMF and the EU AI Act.

## Where TrueFoundry 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; TrueFoundry is a central gateway with no on-device discovery documented.
- SealGate keeps local stdio servers on the device through a tunnel; TrueFoundry runs stdio-style MCP servers gateway-side with managed commands and credentials.
- SealGate governs the agent CLI as well as MCP and the LLM API; TrueFoundry governs the LLM API and the MCP tools that flow through the gateway.

## TrueFoundry 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 | TrueFoundry |
| --- | --- | --- |
| How local stdio MCP servers are handled. Whether your local MCP server stays on the device or is shipped elsewhere. | Tunnel in place (Yes) | Gateway-hosted (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 | – Not publicly verified |
| 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 | ✓ Yes |
| Low latency overhead. Minimal added latency on the tool-call path. | ✓ Yes | – Not publicly verified |
| Open source core. An open, inspectable core rather than a closed proxy. | ✕ No | ✕ No |

Bottom line: TrueFoundry is a security-strong enterprise gateway that governs LLM and MCP traffic from a central hub; SealGate governs the same traffic from a device-level agent that keeps local servers on the endpoint, discovers shadow MCP, and covers the agent CLI.

## Frequently asked questions

Is SealGate more secure than TrueFoundry? They take different shapes rather than one being strictly more secure. TrueFoundry is a strong central gateway with runtime guardrails, DLP, credential vaulting and SOC 2 Type II and HIPAA certification. SealGate governs the same LLM and MCP traffic from a device-level agent, so it keeps local stdio servers on the machine, discovers shadow MCP servers on the endpoint, and covers the agent CLI. If your priority is on-device control and endpoint discovery rather than a central hub, SealGate is the alternative.

What is TrueFoundry? TrueFoundry is a commercial enterprise AI and MCP gateway that centralizes inbound auth, RBAC, credential vaulting, runtime guardrails and observability across LLM and MCP traffic, deployable in your own cloud and certified SOC 2 Type II and HIPAA.

What are the main limitations of TrueFoundry? The clearest gap for teams focused on runtime data security: SealGate runs a device-level agent and discovers shadow MCP servers on the endpoint; TrueFoundry is a central gateway with no on-device discovery documented. Weigh this against your own priorities before deciding.

Is TrueFoundry worth it? It depends on the axis you care about. TrueFoundry is a security-strong enterprise gateway that governs LLM and MCP traffic from a central hub; SealGate governs the same traffic from a device-level agent that keeps local servers on the endpoint, discovers shadow MCP, and covers the agent CLI. Compare the two on the capabilities that matter to you.
