Ewon puts a rugged VPN router in front of a machine so an engineer can reach the PLC behind it through Talk2M. ThinRemote takes a different route: a software agent on the device itself that adds observability, SSH, web-service access, remote desktop, files and fleet automation, with no appliance to buy.
ThinRemote operatesThis is not a like-for-like contest. Ewon is a hardware VPN appliance built to reach the equipment behind it; ThinRemote is a software agent built to operate the device it runs on. The real question is what your team actually needs to do once it connects.
A Cosy or Flexy industrial router sits on the machine's LAN and brokers a secure VPN through the Talk2M cloud, so an engineer can reach the PLC or HMI behind it. It is a proven, PLC-oriented, ruggedized product, and the Flexy adds fieldbus data acquisition. It is also a box you buy, wire in and maintain for each machine or site.
One small outbound agent runs directly on any Linux device, gateway or edge computer and gives you live telemetry, alarms, SSH, web-service access, remote desktop, files, fleet automation and an MCP server for AI agents, out of the box. No proprietary hardware, and you manage the whole device, not only the tunnel to a controller.
With Ewon, remote access starts with hardware: a Cosy or Flexy router per machine or site, wired into the LAN, powered, provisioned and kept up to date. That box is exactly what makes it robust, and it is also inventory, lead time and a spare you keep on the shelf for every deployment.
ThinRemote is a single static binary, under 10 MB, that you install on hardware you already have. It runs on almost anything, from a modern edge server to a years-old industrial box (kernel 2.6 and up, 16 architectures), makes one outbound connection and changes nothing about the device's own networking. Add a device by installing the agent, not by ordering a router.
Ewon's data features are built around the equipment on the machine LAN: a Flexy can poll PLC and sensor tags over Modbus, EtherNet/IP, OPC UA and more, log them and raise tag-based alarms by email or SMS. That is genuinely useful for process values, and it is aimed at the controller, not at the box doing the connecting.
ThinRemote reports the health of the device itself. Every agent publishes a structured monitoring resource: CPU and load, memory, per-filesystem usage, network throughput, temperature and uptime, shown on per-device and per-fleet dashboards and wired into threshold alarms over email or webhook. Expose any value from a small script and it becomes a first-class metric you can chart, roll up across the fleet and alarm on, no extra gateway required.
A Talk2M session gives you network reach to the equipment behind the router, and then you bring your own tools over it. That is the right model when the thing you care about is a PLC or HMI on the far side of the box.
ThinRemote treats the device as something you operate directly. Over the same outbound agent you get an in-browser terminal and SSH, a file explorer, remote desktop, and HTTP/TCP/TLS tunnels to any local web UI or service, plus the ability to turn a script into a named, callable device API. And you drive it three ways over one auth model: a web console, a scriptable CLI with JSON output, and a built-in MCP server for AI agents.
Ewon is configured per unit: each Cosy or Flexy is provisioned and updated as its own device, which is a natural fit when a machine builder ships one box with one machine. Applying the same change across hundreds of them is a job you take on yourself.
ThinRemote makes the whole fleet programmable. It brings playbooks: describe a change once, try it on a single device in check mode, then roll it out across the product in controlled batches that stop on their own if too many devices fail. The same flow runs from your terminal, a CI/CD pipeline over the CLI's JSON output and exit codes, or an AI agent over MCP, all under the same roles and tokens.
Both products share a sound core idea: the device dials out, so there is no inbound port to open on the plant firewall. Ewon does this well, and does it in hardware. The Cosy+ adds a secure element for a hardware root of trust, secure boot and x509 TLS, and the Talk2M cloud it connects to is ISO 27001 certified. That is a real strength worth acknowledging.
ThinRemote reaches the same outbound-only posture in software. The agent opens a single outbound connection over TLS 1.3, exposes no listening port, and access is brokered through the cloud with token-scoped RBAC and an audit trail shared across the web console, CLI and MCP. Thinger.io, the platform behind ThinRemote, is ISO 27001 certified.
Both dial out, so no inbound port is exposed. Ewon brokers a VPN to the PLC behind a hardware router; ThinRemote brokers operator access to the whole device in software.
Ewon's world is a VPN and a set of industrial protocols. There is no AI-agent surface to point a model at, so anything an assistant might do you would have to build and maintain yourself on top of the connectivity.
ThinRemote ships an MCP server built into the CLI. Point Claude, Cursor or any MCP client at it and it can list devices, read live metrics, run commands, tail logs, open tunnels and roll out playbooks, all in plain language and all under the same roles and tokens as your team. Ask "which gateways are low on disk?" or "roll the update to Madrid first", and it acts on the real fleet.
The details a technical evaluator actually compares, side by side. Ewon here means the Cosy / Flexy routers together with the Talk2M cloud.
product execA fair reading: Ewon is purpose-built to reach a PLC behind a rugged router, and it is very good at that. Several ThinRemote advantages here come from being a software agent that operates the whole device, which is a different job. Talk2M plan limits (for example, concurrent VPN connections) vary by tier; check the current Ewon plans for specifics.
Different jobs. If the problem is reaching a controller behind a rugged box, reach for Ewon.
When the target is a PLC or HMI you can't or won't install an agent on, a hardware router in front of it, isolating the machine LAN, is exactly the right tool.
Native Modbus, EtherNet/IP, PROFINET, OPC UA and serial polling of PLC tags, with on-device logging, is the Flexy's home turf.
DIN-rail hardware for harsh environments, a hardware root of trust on the Cosy+, and an ISO 27001 certified Talk2M cloud available today.
Plenty of sites run both: an Ewon router where a PLC needs one, ThinRemote to operate the Linux gateways, IPCs and edge computers around it.
Pick by the question you're actually trying to answer.
"I need to operate, observe and fix a fleet of Linux devices, no new hardware."
"I need a rugged VPN box to reach a PLC or HMI behind it."
Install the agent in seconds and get observability, SSH, web-service access, remote desktop, files and fleet automation from one outbound connection.
