01 / WHAT WE DO

Built to run.
Designed to last.

Development and security belong in the same conversation. We work from architecture and implementation through authorised testing, remediation and verification.

Software development

Custom applications, APIs, integrations and commerce platforms. We turn practical business requirements into maintainable software and stay involved through delivery.

Authorised penetration testing

Web applications, APIs and infrastructure assessed against an agreed scope. Reproducible findings, clear priorities and retesting give your team a practical path to remediation.

Application security

Security reviews, threat modelling and vulnerability remediation across the development lifecycle. We connect code-level findings with the systems that run the software.

Talos & platform engineering

We build and operate Kubernetes on Talos Linux: a minimal, immutable operating system with security built into its architecture. Declarative configuration and GitOps keep changes controlled and repeatable.

02 / DEFENSIVE SECURITY

Better visibility.
Stronger defence.

Security testing should produce an outcome your engineering team can act on. We connect application knowledge, controlled testing and operational evidence to understand exposure, resolve causes and verify the result.

Observe
Bring security telemetry into view.
Investigate
Understand the signal and assess the risk.
Remediate
Fix the cause with controlled changes.
Verify
Confirm the result in the running system.

AI-ASSISTED. HUMAN-ACCOUNTABLE.

More capability.
Clear boundaries.

Our approach to AI-assisted security centres on systems we own or have explicit permission to assess. The scope, data and consequences determine the controls.

Defined scope and authorisation
Redacted evidence and controlled data access
Human review of findings and consequential changes
Validation in isolated environments where appropriate

Our security & responsible AI approach

KUBERNETES / SECURE BY DESIGN

A stronger foundation.
With Talos Linux.

Our Kubernetes infrastructure runs on Talos Linux. Purpose-built for Kubernetes, Talos reduces the operating-system attack surface and makes secure defaults part of the foundation.

Explore Talos Linux

Minimal & immutable: A dedicated operating system with only what Kubernetes needs.
No SSH. No shell.: Node administration uses an API secured with mutual TLS.
Declarative operations: Versioned configuration and reviewed GitOps changes, with responsibility for operation staying with us.

03 / WHO WE ARE

Swiss roots.
Engineering mindset.

UHL is the development, penetration-testing and engineering profile of UHL-Services, the Swiss business behind UHL Hosting. Founded in 2014 in Adliswil, we have spent more than a decade working with open technology and the businesses that depend on it.

Our work spans infrastructure, application platforms and automation. We adopted AI years ago and apply it as part of the engineering process, with responsibility for the result staying with people.
