Good IT decisions start with the right questions.
Clear, practical answers about IT infrastructure, cybersecurity, AI automation and custom software for small and mid-sized businesses.
01IT strategyWhere should a business start with legacy IT infrastructure?
Start with a structured inventory: systems, responsibilities, dependencies, access rights, backups and the most important business processes. HDN then prioritizes immediate risks and develops a realistic roadmap—from quick security improvements to gradual modernization. This prevents isolated purchases and creates a system that remains maintainable.
Explore the topic02Regional supportDoes HDN support businesses in Tyrol, the Allgäu and throughout the DACH region?
Yes. In Tyrol and the Allgäu, we combine personal on-site support with secure remote service. Projects in the wider DACH region can be handled remotely or in a hybrid model. The right setup depends on the infrastructure, the project and the required response time.
Explore the topic03Managed ServicesWhat is the difference between occasional IT support and Managed Services?
Occasional support reacts when a problem has already occurred. Managed Services continuously monitor defined systems, coordinate updates, check backups and document recurring tasks. The goal is predictable operation, clear responsibilities and fewer avoidable outages.
Explore the topic04CybersecurityIs a security review or pentest worthwhile for a small or mid-sized business?
Yes—especially when email, remote access, cloud services or business-critical systems are in use. The scope must fit the actual risk. HDN examines the agreed attack surface, documents findings comprehensibly and prioritizes measures by impact and urgency. Intrusive tests are carried out only with explicit authorization and a clearly defined scope.
Explore the topic05RansomwareHow can a business prepare for ransomware and IT outages?
The foundation includes multi-factor authentication, prompt security updates, restricted privileges, segmented systems and reliable backups. Backups should be protected from direct modification and restoration should be tested regularly. An emergency plan must also define contacts, decision paths and the first steps when systems are unavailable.
Explore the topic06AI automationWhich processes are suitable for AI and automation?
Good candidates are recurring, rule-based or data-intensive tasks—for example classifying enquiries, preparing documents, transferring information between systems or supporting internal knowledge searches. We first check data quality, risk and measurable benefit, then build a small pilot before automating a process at scale.
Explore the topic07Data protectionHow can companies use AI without losing control of sensitive data?
Employees need approved tools and clear rules for personal, confidential and customer data. Access rights, data flows, retention, logging and human review must be considered before productive use. HDN designs the technical and organizational framework to match the use case and the company's protection requirements.
Explore the topic08SoftwareWhen is custom software better than another standard product?
Custom software makes sense when a central process cannot be represented economically with standard tools, when multiple systems need clean integration or when manual work causes recurring errors. Before development, HDN checks whether configuration, an interface or an existing product would already solve the problem.
