Guard.ch is developed and operated by Zesiger.net in Schmiedrued, Switzerland. We build isolated browsers for teams investigating unfamiliar websites. Here is the problem we set out to solve and the products that led us here.
Read the storyA link arrives by email, in a chat or in a ticket. Nobody on the team knows whether it is safe. A proper investigation calls for an isolated environment, a separate exit IP and a way to see what the page does. Too often that means a spare VM and a folder of screenshots. We wanted to make it simpler.
“Hey, is this real?”
the question most investigations start with
Give Guard.ch a URL. The page opens in an isolated browser on our infrastructure. Choose an exit location, watch it live and take control when you need to, such as for a sign-in. Alongside the page, you can inspect requests, redirects, downloads, trackers and contacted domains. Registry, IP and certificate data is available on demand. When the investigation ends, we remove the container. We do not save an analysis report or a recording of the session.
An investigation should be easy to start and easy to question. Every assessment shows the signals behind it. Live analysis ends with the session, while a browser profile remains available only if you choose to save one.

Product and operations togetherThe same team runs the site, analysis service and browser infrastructure, so product decisions stay close to day-to-day operations.
Stored in HelsinkiAccount and billing records are held in an EU datacenter there. Live findings disappear when an investigation ends.
SOC 2 and ISO 27001 are planned but not yet attested.
IP and network data made easy to find. Now retired, but still part of our story.
Lesson one: put context beside what you are investigating.
A remote browser you control from a normal tab. We run the isolated infrastructure for hundreds of thousands of people.
Lesson two: isolation works best when the browser feels easy to use.
Both ideas brought together for teams: an isolated browser with live analysis and an interface for AI agents.
Lesson three: people and agents should be able to work in the same live session.
Zesiger.net also builds software and integrations for Swiss clients. For custom work, contact them through their own site.
