Approach II

One standard,
in three movements.

III.

Method V

Six steps,
one direction.

From the first meeting to daily oversight, a proven method that doesn’t get reinvented along the way.

  1. 01
    Audit

    An honest baseline. What exists, what’s constrained, what’s actually used.

  2. 02
    Prioritisation

    What matters first. What can wait. What must be dropped.

  3. 03
    Proposal

    A sober architecture, a clear budget, deadlines that hold.

  4. 04
    Deployment

    Installed, configured, documented. With your teams, never against them.

Questions VI

The questions
you’re asking.

Twelve concerns come up before every engagement. Here are our answers, without detour.

Every proposal is priced after audit. No trapped flat rates, no hidden costs. The budget is known before signing — and held after.
From a few days for a fix to a few weeks for full infrastructure. The schedule is set and shared from the proposal phase.
Gradual handover, no rupture. We work with them, then take over. Your data stays yours, your contracts stay readable.
Existing hardware is reused whenever possible. We replace only what deserves it — no more, no less.
European hosting, GDPR-compliant, 3-2-1 backups, end-to-end encryption. And a yearly audit shared unconditionally.
A human team reachable 24/7 that knows your environment. Augmented by our AI to respond faster — but a human always decides. Proactive oversight: we often detect before you do.
Yes. Unified oversight, homogeneous standards, one contact for 2 sites or 20. Your local teams get the same SLAs everywhere.
Our processes are aligned with these standards (ISO 27001 for IT, NF&A2P for security, GDPR everywhere). Yearly audit shared unconditionally, register of processing on request.
Yes, by default. Audit your stack, gradual integration, replacement only when criticality or end-of-life requires it. Savings are quantified in the proposal.
Yes, within 48-72h for a critical intervention (outage, urgent migration, security incident). Fast-tracked audit, mobilised team, tight schedule. Urgency cost is transparent.
Full continuity. 24/7 on-call is staffed by our own team, never subcontracted. Reinforcement calendar shared at the start of each year.
No hidden exit penalty. Reasonable notice, documented handover, transition support. Our commitment is trust — not contractual lock-in.
