# Subprocessors

Last updated: 11th September 2026

SealGate uses the following third-party service providers (subprocessors) to help deliver our SaaS (self-serve cloud) product. We maintain appropriate data processing agreements with each subprocessor and ensure they meet our security and privacy standards.

Applies to SaaS only: This list applies exclusively to SealGate's SaaS (self-serve cloud) offering. Customers on VPC, Self-Hosted, or Air-Gapped deployments are subject to a different (and substantially smaller) set of subprocessors. Air-Gapped deployments use none of the subprocessors below -- by design, no customer data leaves the customer's environment. Contact us for the deployment-specific schedule that applies to your contract.
