Services

As an IT service provider I come to you in Vienna and the surrounding area and work remotely for all of Austria: IT support, networking, firewall, VPN, cybersecurity, servers, Microsoft 365, software development. You get a fixed contact person, documented work and clear prices.

Remote services

Via secured access to your systems, with alignment by video call, ticket or chat.

Linux server administration

Installation, hardening, updates, monitoring and troubleshooting for AlmaLinux, Rocky, Debian and Ubuntu. Reliable operations instead of surprises.

Java development

Backends, REST APIs, automation tools and integrations in Java. Experience from leading a multi-year cloud gaming project with proxy infrastructure.

PHP development

PHP 8 with a focus on security: WHMCS and Plesk modules, payment and registrar integrations, REST APIs and custom web applications.

Software development

Programming assignments in Python, Node.js, TypeScript, Java, PHP, Go, Bash and PowerShell: backends, APIs, bots, automation and integrations that can actually be operated.

Website development

Company websites that load in a fraction of a second, rank on Google and comply with GDPR. Custom-built or based on a CMS.

Ansible automation

Playbooks, roles, AWX and Ansible Automation Platform: reproducible servers, automated patch days and rollouts across multiple stages.

Cloud and virtualisation

Proxmox VE, XCP-ng, KVM, Docker, Swarm and Kubernetes: private cloud platforms, container operations and hybrid architectures that fit the budget.

Load balancers and high availability

Resilient load balancer clusters with HAProxy, nginx or LVS and keepalived: TLS, health checks, failover within seconds and automation with Ansible.

Network administration

Enterprise switches, VLANs, routing up to BGP, IP concepts for IPv4 and IPv6, monitoring and the analysis of stubborn faults.

Firewall and network security

Rule sets you can understand: OPNsense or pfSense, Linux firewalls with nftables, segmentation, IDS/IPS and high availability, set up remotely and documented.

VPN and site-to-site networking

Connect sites, home office, cloud and data centre securely: WireGuard, IPsec or OpenVPN with two-factor authentication instead of open ports and port forwarding.

DDoS protection and mitigation

When your server, shop or game server is under attack: analysis, protection concept and implementation, terabit-class protection via KernelHost GmbH and emergency help during the attack.

IT security and backup

Server hardening, two-factor and passkeys, monitoring with alerting and backups that actually work when it matters.

Cybersecurity

Find vulnerabilities before others do: external and internal review, hardening, phishing protection, emergency plan and help when it matters, explained in terms management understands.

IT support and managed services

Your external IT department: helpdesk, updates, monitoring and user management, billed based on effort or with an hour bundle, without a monthly fee.

Microsoft 365 and email

Tenant, domain, email migration, Teams, OneDrive and multi-factor authentication set up cleanly instead of guessing in a web console for days.

Windows Server and Active Directory

Active Directory, group policies, file servers, Remote Desktop and Hyper-V: build, migrate and secure Windows Server environments.

Website maintenance

Updates with staging, backups, malware protection, load time and monitoring so your website stays secure and fast.

IT consulting

Vendor-neutral and understandable: inventory, system selection, cloud or own server, security and costs under control.

On site in Vienna and the surrounding area

Installation, maintenance and emergency help directly at your premises, with a travel flat rate of €35 within Vienna.

Wi-Fi and access points

Stable Wi-Fi for office, practice, workshop or home: site survey, access points, guest Wi-Fi and mounting on site in Vienna.

NAS setup

Central storage with RAID, user permissions, secure remote access and a backup concept that survives ransomware.

On-site server maintenance

Hardware diagnostics, disk and RAID replacement, firmware, UPS and server room check: I come to your servers in Vienna and the surrounding area.

Network installation

From patch panel to firewall: I set up your company network on site, cleanly cabled, segmented and documented.

IT emergency and on-site support

Server down, network dead, suspected ransomware? Fast help remotely and on site in Vienna, followed by a plan so it does not happen again.

PC and workstation service

Set up new workstations, transfer data, connect printers, home office with VPN, upgrade and secure devices, right at your premises in Vienna.

Phone system and VoIP

From the ISDN system to modern VoIP telephony: 3CX or cloud system, SIP trunk, IP phones, softphones and number porting.
