About Trout Software
Trout Software builds Access Gate, an on-premise appliance that places a zero-trust access layer in front of operational technology networks. It works as a transparent proxy, so machines keep their addresses, firmware and vendor support and need no agents. Services include an automatic asset inventory, secure on-site and remote access with recorded sessions, shielding of legacy PCs and controllers that cannot be patched, and compliance logs and reports.
Customers are manufacturers, defense manufacturers and primes, industrial groups, utilities and water systems. Access Gate is sold as a bundled appliance with software, updates and support. The self-serve Starter plan covers one plant with up to 200 machines, at $780 for the appliance and $399 per month for license and support. Enterprise deployments are priced per site, at $11,240 for a main site and $5,745 for a small site, after a review with a Trout engineer.
The company was founded in 2022 and is headquartered in Paris, France. It also lists offices in Kingston, New York and Dublin, Ireland. The company states that its product is deployed in Europe and North America.
Product: Access Gate, an on-premise OT network security appliance with zero-trust access, asset visibility, session recording and compliance reporting.
