On-Prem Applications
Full apps inside your walls.
Advanced Capabilities
Secure & Air-Gapped System Development
Software and infrastructure for private networks, restricted environments, offline systems, and secure deployments.
Overview
Hexmon designs and deploys software for private networks, restricted infrastructure, edge environments, and air-gapped systems where control matters.
Hexmon will architect, build, and deploy on-prem and air-gapped systems that respect your boundary by design.

Frequently asked questions
What is an air-gapped system?
An air-gapped system is software and infrastructure that runs entirely without a path to the public internet. All compute, storage, identity, and updates stay inside a controlled local network, isolating the environment from external networks by design.
Can software run without internet?
Yes. Hexmon designs offline-first applications that store data locally, authenticate locally, and continue working through outages or in environments where connectivity is restricted or unavailable.
How are updates handled?
Updates ship as signed, versioned packages staged through your change-control process. They can be delivered by physical media, an internal repository, or a controlled one-way sync channel — never automatic over the public internet.
Can AI systems run on-prem?
Yes. AI assistants, RAG, computer vision, and analytics can run fully on-prem or air-gapped on local GPUs and accelerators, using open-source or licensed models — without sending data outside your environment.
Can dashboards and reports work locally?
Yes. Dashboards, reports, alerts, and audit views run on local servers and are accessed through your internal network — with role-based access and full audit logging.
