Why arian
What sets us apart from other IT service providers in Düsseldorf and Bonn
Personal instead of anonymous
With us, you know your contact person by name. You reach directly the technician who knows your systems and who responds within 30 minutes. Our customers in Düsseldorf, Neuss and Meerbusch notice this especially when things need to happen quickly.
Transparent instead of complex
We clearly state what works, what doesn't and what it costs. Fixed monthly costs instead of complex offers. No hidden costs, no surprises on the invoice. Not the cheapest and not the largest IT service provider in NRW but the most reliable.
Cloud-First by conviction
Microsoft 365, because it's scalable, secure and maintainable. We accompany companies in Düsseldorf, Köln and Bonn during migration and back up your data every two hours with automatic backup. No local server burden, no isolated solutions.
Compliance as infrastructure
GoBD, GDPR, NIS2 for us are not checkboxes on a checklist, but part of your IT architecture. We document cleanly according to BSI-Grundschutz, so you can sleep soundly during audits. For companies that take compliance seriously instead of just talking about it.

FAQ
Frequently asked questions about our IT service
Do we need arian Protect if we already have antivirus software on all devices?
Traditional antivirus protection only detects known threats. arian Protect combines Endpoint Detection & Response with centralized monitoring and automated patch management – measures that the BSI recommends for companies of all sizes. In our daily work, we see that most security incidents at SMEs begin with unprotected endpoints. Windows Defender alone does not cover this depth.
Is arian CloudProtect worthwhile if Microsoft 365 already has backups itself?
Microsoft secures its infrastructure, not your data. If an employee accidentally deletes emails or files, they are irrecoverably lost after a short time. arian CloudProtect backs up your M365 data every two hours and enables recovery within minutes. GoBD and GDPR compliant and audit-proof. This is indispensable especially for companies in Düsseldorf, Köln and Bonn that rely on dependable cloud backup.
How does support work with arian Complete and Complete+?
With arian Complete+ remote support is included as a flat rate (Fair Use). Your employees contact us directly without costs arising per request. With arian Complete you book support as needed in 15-minute intervals. In both cases, we work via secure remote maintenance directly on the affected device. You always reach a technician who knows your systems – usually within 30 minutes.
What about data protection and GDPR with remote support?
Our remote connections are encrypted and are only established with user consent. Each session is logged. We work exclusively with GDPR-compliant tools and store no personal data on our systems. This applies to every customer whether in the Düsseldorf, Köln, Bonn area or nationwide.
Can I book or cancel arian Protect and arian CloudProtect flexibly?
Yes. All our products can be booked without minimum contract terms. You can cancel monthly. No hidden costs, no restrictive contracts. You only pay for what you use. Flexibly adaptable to your company size – this applies to small teams as well as growing medium-sized businesses.
How does onboarding work at arian IT Service?
After the free initial consultation we analyze your IT landscape: devices, licenses, security gaps. Then we create a concrete onboarding plan – secure endpoints, set up M365 backup, activate monitoring. For most companies with 10 to 50 workstations, you are productive within three to five working days, without downtime.
You're in Düsseldorf and Bonn. Can we also work with you from further away?
Absolutely. Our IT services are 100% remote-capable. We support customers nationwide. We offer on-site deployments in the NRW region: Düsseldorf, Bonn, Köln and the entire region in between – Neuss, Meerbusch, Ratingen, Dormagen, Leverkusen, Bergisch Gladbach, Troisdorf, Siegburg. Our support works just as reliably remotely.
