IT Systems House Rosenheim – IT for the Inn valley and southern Upper Bavaria
With a good 65,000 inhabitants, Rosenheim is the economic centre of south-eastern Upper Bavaria and an important hub along the A8 between Munich and Salzburg. The region is characterised by a unique mix: manufacturing SMEs, the timber and construction industry in the Inn valley, a strong tourism and hospitality industry around Lake Chiemsee and the neighbouring Alpine foothills, plus an unusually dense landscape of tax consultancies, law firms and notary's offices in the city centre. For all these companies, we deliver the digital infrastructure as an IT systems house in Rosenheim – GDPR-compliant, with our own data centre and a dedicated point of contact.
SMEs and manufacturing industry in the Inn valley
Along the Inn valley, family businesses in timber processing, mechanical engineering, construction and food production have established themselves over generations. For these companies, failover-reliable telephony, site networking between plants in Rosenheim, Kolbermoor, Raubling or Bad Aibling and GDPR-compliant data storage are central requirements. We build hybrid cloud architectures in which local servers in the plant work seamlessly with Microsoft 365, and connect several sites via secure VPN connections into a unified IT environment.
Hospitality and tourism on Lake Chiemsee
The tourism region around Lake Chiemsee, Bad Aibling and the neighbouring Alpine foothills has its own requirements: reservation systems, professional phone systems for hotels and guesthouses, failover-reliable Wi-Fi infrastructure for guests and staff, integration of booking platforms and CRM systems. We implement cloud phone systems with professional greeting announcements, automatic forwarding and multilingual configuration – important arguments in a region with international guest traffic.
Law firms and the liberal professions in Rosenheim
Rosenheim's city centre is home to an unusually high density of law firms, tax consultancies and notary's offices. For these sectors, client protection, failover-reliable telephony with call logs and compliance with confidentiality obligations are central topics. We implement cloud phone systems with queues, automated answering machines and client-specific permission structures in SharePoint.
Short distances from Freising
Our headquarters in Freising is usually in Rosenheim within 90 minutes via the A92 and the A8. This means we combine short response times with the technical depth of an established systems house with its own data centre. For commissioning, hardware changes or larger rollouts we come on site; by far the largest part of our work is done via secure remote maintenance.
Cloud hosting in a German data centre
Our managed cloud services run exclusively in a German, GDPR-compliant data centre. For Rosenheim industrial customers, tax consultants and notary's offices, this is an essential prerequisite – no data routes abroad, no Cloud Act risks. Failover protection with redundant hosts, SAN storage and automated backups against ransomware are part of the standard package.
Personal, committed, long-term
With us, you have a dedicated point of contact who knows your IT over the years. No changing hotline staff, no anonymous ticket system – but people who understand your architecture, your industry and your requirements. It is precisely this combination of personal closeness and the depth typical of a systems house that SMEs in the Inn valley and southern Upper Bavaria look for in an IT partner.
