What we do
One team. One point of contact. Reliably managed IT.
IT Infrastructure
Servers, networks, Wi-Fi, firewalls and employee devices: we design, procure and document the technical foundation of your business. Existing components remain in place when they can continue to operate securely and economically.
- Microsoft Server / Linux
- Firewalls (Sophos, Fortinet)
- PCs, laptops & mobile devices
IT Consulting
We turn your requirements into a defensible decision. You receive a clear comparison of value, cost, risk and operating effort before committing to a product or provider for the long term.
- Requirements and software selection
- IT roadmap and investment planning
- Audit and funding preparation
IT Security
We assess systems, identities, endpoints, email, networks and recovery. The result is a prioritised action plan with effort and ownership—not an unstructured collection of technical findings.
- Security reviews and BSI-aligned gap assessments
- Penetration testing with an agreed scope
- NIS2 and customer-audit preparation
AI Implementation
We introduce Claude and other appropriate AI tools through one concrete business process. Data, access, quality control and measurable value are resolved before rollout.
- AI readiness and use-case selection
- Claude for Work/Enterprise and secure integrations
- Pilot, governance and user training
Managed Services
From a preconfigured notebook to secure offboarding, we manage devices, applications, updates and access centrally while keeping inventory and documentation current.
- Onboarding and offboarding
- Microsoft Intune and Windows Autopilot
- Operating-system, software and security updates
Managed Security
We combine endpoint protection, EDR/XDR, email security, identity and awareness into an ongoing security programme. We offer 24/7 monitoring only where an appropriate MDR service is contracted.
- Microsoft Defender or Sophos Endpoint/EDR/XDR
- Sophos MDR and defined escalation paths
- Sophos Email, Phish Threat and data loss prevention
Managed Cloud
We migrate and operate Microsoft 365, Azure and hybrid environments. Permissions, security, backup, cost and user adoption are designed as one operating model.
- Azure and Microsoft Entra ID
- Exchange Online, Teams, SharePoint and OneDrive
- Migration, backup and hybrid operations
Qualifications & Partnerships
Certified. Vetted. Recognized.
Our Promise
A calm IT setup isn’t luck. It’s preparation.
You get named contacts, usable documentation and clear ownership. When several vendors are involved, we coordinate the solution instead of sending you between support desks.
Our Projects
Selected projects from German SMEs.
Microsoft 365 Migration for Cormos Medical
We migrated local user accounts and the Exchange server to Microsoft 365. The new environment simplified operations and maintenance and improved measured availability. According to the project evaluation, infrastructure costs fell by 16%, operating costs by 37%, and availability reached 99.9% during the stated measurement period.
Migrating our local user accounts and Exchange server to Microsoft 365 has sustainably modernized our IT infrastructure. The transition drastically increased the availability of our services. At the same time, we were able to reduce both our infrastructure and operating costs. We now have a more reliable, scalable, and cost-effective solution that lets us focus more on our core business again.Dr. Robert Moszner, CEO, Cormos Medical GmbH
Network Modernization with Starlink Backup for General Transports
We renewed workplace and network hardware and added Starlink as a secondary internet connection. Measured download speed rose from around 4 to 110 Mbit/s, internal network speed from 15 to 150 Mbit/s, and availability from 85% to 99.9% during the stated measurement period.
Installing and migrating our workstation hardware and network components, along with setting up a Starlink backup connection, has fundamentally improved our IT infrastructure. Increased availability was especially important for our operations, thanks to the Starlink connection. Our download speed and overall network speed have also improved considerably. Our team now benefits from a fast, stable, and reliable infrastructure.René Gröger, Managing Director, General Transports GmbH
IT Security Audit for a Property Developer
The audit identified and closed twelve critical vulnerabilities. MFA coverage increased from 15% to 100%, endpoint protection from 67% to 100%, and nine obsolete firewall rules were removed.
The IT security audit gave us a clear, transparent view of our existing vulnerabilities and concrete opportunities for improvement. Critical vulnerabilities were identified and resolved, and our MFA coverage and endpoint protection were both significantly increased. We also removed firewall rules that were no longer needed. As a result, we’ve meaningfully reduced our attack surface and improved the security posture of the whole company.Managing Director, Anonymized
