Four pillars of on-premise deployment

  • Total sovereignty

    No cloud callback, no outbound telemetry, no foreign dependency. Your perimeter stays your perimeter.

  • Air-gap compatible

    Compatible with isolated zones and classified environments (II 901, IGI 1300). Updates transferred via controlled channels.

  • Code delivered & signed

    Signed source, auditable. Documented reversibility plans (code delivery at end of contract).

  • 24/7 MCO + MCS

    Operational maintenance AND security maintenance, operated from national territory by cleared teams.

    Code and binaries delivered on sovereign infrastructure, no cloud callback. Verifiable signatures.

  3. 03

    CERT / SOC integration

    SIEM connectors, shared runbooks, encrypted exchanges with your CERT or internal SOC.

  4. 04

    Continuous MCO

    24/7 platform health monitoring, escalation, hotfixes by cleared teams.
