Why Opsora?

Why Opsora, not a large consultancy?

Senior-led architecture from assessment to handover

A senior architect leads every engagement and is your direct contact - no account manager handoffs

Defined phases and a documented handover. Not an open-ended engagement

Each phase has a clear output. The engagement ends with a handover your team can work from independently.

You talk to the person doing the work

The architect you meet in the briefing is the one who delivers

No dependency model: we build what your team can run without us

Every engagement ends with full documentation and a trained team. No retainer required, no artificial dependency.

Common Challenges

Does this sound familiar?

These challenges are solvable with the right architecture and a dedicated senior architect.

  • You have a NIS2 compliance deadline. Your gap analysis has not started.
  • An acquisition or divestiture is forcing a tenant split or consolidation, and you need it done on a fixed date.
  • Microsoft 365 is in production, but guest access, Teams sprawl, and Conditional Access policies were never properly configured.
  • Leadership has approved Copilot. Your data classification is incomplete and your oversharing exposure is unknown.

If any of these sound familiar, we should talk.

Success Stories

In Practice

Real outcomes from real implementations: measurable improvements for IT teams

Zero on-prem identity – complete migration from Active Directory to Entra ID
Technology~200 users2024

CHALLENGE

Every hybrid identity environment is a risk accumulator – on-prem infrastructure to maintain, two failure surfaces to monitor, and legacy dependencies that block every modernisation decision downstream.

OUTCOME

Active Directory decommissioned. All devices cloud-native on Entra ID. No on-prem identity infrastructure remaining – simpler IT operations, stronger security posture, no legacy overhead on future decisions.

M365 security rebuild and governance programme – 22 locations, zero disruption
Security & Infrastructure2,200+ users2023

CHALLENGE

Across 22 locations, users were operating on an under-configured M365 environment – default settings, unclear permission structures, and no consistent device management. The risk exposure was real and growing.

OUTCOME

Stable, secure M365 environment across all 22 locations – measurably faster administration, clearer governance, and an IT team running the environment independently.

Carve-out after acquisition – cross-border IT migration program
Cybersecurity145 users2024

CHALLENGE

After being acquired by new ownership, a cybersecurity company with teams across Germany, Italy, and the UK had to stand up its own IT infrastructure - while the former parent restricted access and required formal approval for every migration step.

OUTCOME

Carve-out completed on schedule across 15 departments, 3 countries, and 145 employees - zero downtime, despite limited cooperation from the former parent.

Our Methodology

How every engagement is structured

Developed across 18+ years and DACH mid-market environments. No open-ended timesheets. Structured outcomes at every stage.

01

Assess

Current environment audit and gap analysis against your compliance and governance requirements.

Typically 1-2 weeks

02

Architect

Governance blueprint and security baseline tailored to your tenant, team, and regulatory obligations.

Typically 1-3 weeks depending on scope

03

Implement

Phased rollout, test-before-prod policy, and knowledge transfer at each stage. No surprise changes.

Typically 2-8 weeks depending on complexity

04

Sustain

Structured handover documentation, optional quarterly reviews, and direct access to Tobias for follow-on questions.

Handover in final week; optional ongoing from there

Every engagement follows this structure, from initial assessment through to documented handover.

Risk

The cost of getting it wrong

A failed M365 migration for a 500-user company typically costs €200,000+ in lost productivity, rework, and delayed timelines. A compliance gap that triggers a GDPR fine can cost 4% of annual revenue. Under NIS2, a significant incident that is not properly reported can result in fines of up to €10M or 2% of global annual turnover.

Senior architecture prevents the scenarios that cost more. It is not priced differently.

The underlying gaps that create these risks can typically be resolved within a single structured engagement.
