Decionis vs Lasso MCP security gateway
An MCP security gateway inspects traffic at a proxy; an execution authority binds permission to the proposed action and records signed evidence.
Public sources checked . Our architectural assessment follows the scope of the sources below. Send a correction; accepted corrections update this date.
When is Lasso MCP security gateway the better choice?
- Your problem is inspection of MCP traffic.
- You need a gateway in front of MCP servers.
- Content-layer threat controls are the immediate requirement.
- A gateway's controls and your logs already meet your evidence needs.
What changes at the execution boundary?
| Dimension | Decionis | Lasso MCP security gateway |
|---|---|---|
| Control boundary | One exact action, with authority re-evaluated immediately before commit. | Lasso's open-source MCP gateway announcement describes a security layer between agents and MCP servers, with inspection and policy enforcement. |
| Evidence | Signed Decision Dossier; verify the covered artifacts with the appropriate public keys, without an account. | That announcement does not describe a per-decision artifact with offline public-key verification. It is not an inventory of every capability in Lasso's current portfolio. |
| Deployment responsibility | The integrating host must isolate credentials, prevent bypass and enforce the decision. | Evaluate the chosen deployment and its enforcement boundary; a product category is not evidence of a specific installation. |
| Procurement posture | SOC 2 in progress. These pages address engineering and architecture, not certification equivalence. | Obtain current assurance documents and check the service and deployment they cover. |
Decionis contract: enforce-and-bind, claim-before-commit and finalize. Signature validity is separate from execution eligibility and downstream effect confirmation.
Can these controls work together?
A gateway can inspect a call before an execution authority evaluates it. Confirm the integration; neither a proxy nor a signed record alone establishes complete deployment security.

This preloaded dossier has real Ed25519 signatures over synthetic data from the public Agent-Safe corpus. Its test key is deliberately public. It demonstrates verification and tamper detection; it is not customer evidence, a production signature, or permission to execute.

After the page or files load, the signature checks need no network. Installing the CLI may require a connection. Valid signatures establish integrity relative to the selected key, not whether the original facts were true.

A capability not described in the cited public material may still exist. This is a technical comparison of documented controls, not a claim of exhaustive vendor testing.
