# Unipile vs Sealgate

How Unipile and Sealgate compare for securing AI agents and their MCP tool calls, and where each one fits.

Last updated: September 2026

Unipile. Unipile is a unified communications API for developers: one REST API, with a Model Context Protocol wrapper, that adds LinkedIn, WhatsApp, email, calendar, Instagram and Telegram to your own product on behalf of the authenticated user, with each connected account hosted in Unipile's EU cloud.

Sealgate. A runtime agentic data firewall that blocks dangerous tool calls before they execute, scans tool traffic for data loss and prompt injection, discovers shadow MCP servers on the device, and streams a provable audit trail to your SIEM.

Bottom line: Unipile is a hosted connectivity API you build a product on, holding each user's account connection in its cloud; Sealgate is a governed gateway an agent connects to directly, keeping the login on the user's device and policy-checking, scanning and logging every tool call.

## Unipile 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 | Unipile |
| --- | --- | --- |
| How local stdio MCP servers are handled. Whether your local MCP server stays on the device or is shipped elsewhere. | Tunnel in place (Yes) | Cloud API (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) | Access API (No) |
| Runtime enforcement. Blocks a dangerous tool call before it executes, not just after the fact. | ✓ Yes | ✕ No |
| DLP, PII and secrets scanning. Inspects tool inputs and outputs for sensitive data at runtime. | ✓ Yes | ✕ No |
| Prompt injection and tool-poisoning defense. Detects and stops injection, tool poisoning and rug-pull attacks. | ✓ Yes | ✕ No |
| Gateway holds the credential. The gateway issues the final call so the agent cannot bypass policy and retry. | ✓ Yes | ~ Partial |
| Shadow MCP discovery. Finds unauthorized MCP servers before they are used. | ✓ Yes | ✕ No |
| Provable per-call audit. A receipt for every call: agent, tool, policy version, result. | ✓ Yes | ~ Partial |
| SIEM integration and export. Streams audit events to Splunk, Sentinel and other SIEMs. | ✓ Yes | ✕ No |
| SSO, SCIM and RBAC. Enterprise identity, group sync and role-based access. | ✓ Yes | ✕ No |
| Tool-level policy. Read and write tiers, per-tool rules and human-in-the-loop approvals. | ✓ Yes | ✕ No |
| Self-host, on-prem or VPC. Run it in your own environment for data residency. | ✓ Yes | ✕ No |
| 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. | ~ Partial | – Not publicly verified |
| Open source core. An open, inspectable core rather than a closed proxy. | ✓ Yes | ✕ No |

✓ Strong or native ~ Partial or via a partner ✕ Not offered – Not publicly verified

## Where Sealgate is different

- Sealgate keeps each account login on your own device through the Beeper connector and a local tunnel; Unipile hosts your users' LinkedIn, WhatsApp and email connections in its EU cloud, so the sessions and credentials live on Unipile's servers rather than the user's machine.
- Sealgate is a runtime security layer: it blocks dangerous tool calls before they run, scans traffic for data loss and prompt injection, and streams a provable audit trail to your SIEM. Unipile is a connectivity API with no runtime enforcement, inline DLP or injection defense.
- Any agent connects to Sealgate directly as an MCP connector with no code, whether it runs locally or in the cloud (ChatGPT, Claude, Codex, Copilot); Unipile is a REST API you build and maintain an integration on top of.
- Sealgate governs the agent CLI as well as MCP and self-hosts in your own environment; Unipile is a closed, cloud-only API hosted in its EU datacenters.

## Frequently asked questions

Is Sealgate an alternative to Unipile? They overlap on giving an AI agent access to channels like LinkedIn, WhatsApp and email, but they are different products. Unipile is a hosted API developers build a product on, and it holds each user's account connection in its own cloud. Sealgate is a governed gateway an agent connects to directly with no code, keeping the login on the user's device and policy-checking, scanning and logging every tool call. If you want runtime security and data control rather than a connectivity API to build on, Sealgate is the alternative.

Does Unipile keep my LinkedIn or WhatsApp login on my device? No. Unipile hosts each connected account in its EU cloud and acts on behalf of the authenticated user through its API. With Sealgate the connector runs on your own machine through the Beeper desktop app, and only tool calls travel through the gateway, so the login and message store never leave the device.

What does Sealgate do that Unipile does not? Sealgate keeps each account login on your own device through the Beeper connector and a local tunnel; Unipile hosts your users' LinkedIn, WhatsApp and email connections in its EU cloud, so the sessions and credentials live on Unipile's servers rather than the user's machine.
