We make your IT more human.
Your IT partner in Bad Düben for networks, servers, security and telephony. Personal support, always within reach.
Innovative solutions for today, lasting success for tomorrow. We look after your IT the way we want our own looked after: reachable, honest and free of jargon.
What we look after for you.
From planning to maintenance. Six areas, one point of contact.
Network & Wi-Fi
Professional Wi-Fi, video surveillance and site-to-site VPN, with LANCOM and Ubiquiti UniFi.
Server & Clients
Microsoft Hyper-V, Fujitsu and Lenovo servers, Windows workstations and document management.
Telecommunications
AGFEO phone systems, planned, installed and maintained. So your customers can reach you.
Building automation
Homematic for heating, lighting and access. Connected to the IT you already have.
IT security
Firewall, backup and malware protection. Our focus, so it gets its own chapter.
Go to securitySecurity you don’t notice. Until you need it.
Network security
We set up and maintain firewalls and VPNs. IDS/IPS spots attacks early, and clean segmentation keeps incidents small.
Backup with Acronis
Automatic backups on site and in the cloud, encrypted in storage and in transit. With an emergency plan for recovery.
Malware protection
Managed antivirus, regular security updates and sandboxing for suspicious files.
Prevention costs less than recovery.

At home in Bad Düben since 2022.
From classic IT services and smart automation to our own data centre infrastructure, artificial intelligence and cybersecurity.
We have kept growing since 2022. What began with classic IT services is now a widening range of modern IT solutions. Innovation, security, reliability and personal support for our customers have always been at the centre.

2022
Laying the foundation
On 15 February 2022, Torsten Lehmann and Marcus Mühlner founded L&M IT GmbH. Our journey began with a focus on classic IT services.
Looking after IT systems, network technology, hardware and software, along with custom solutions for our customers, formed the foundation of our work.
Even then our aim was clear: IT should work reliably, stay understandable and support businesses day to day.

2024
Automation, AI and virtualisation
In 2024, new technologies moved into our focus. IT automation, artificial intelligence and virtual servers in particular became increasingly important.
We worked intensively on optimising existing IT processes, using server resources more efficiently and exploring what modern virtualisation can do.
Our goal was not just to look after IT infrastructure, but to make it smarter, more flexible and ready for the future.
New offices
On 1 October 2024, we moved into our new building on Schwarzbachgrund in Bad Düben, which we share with an electrical contractor, an energy supplier and a fibre-optic company.

2025
Smart offices, modern networks and fresh team spirit
2025 was shaped by practical innovation and personal growth.
By integrating Homematic into our own offices, we made smart building automation part of our everyday work. That let us use new technology in practice and gain valuable experience.
At the same time, we deepened our expertise in professional Wi-Fi and network solutions with UniFi. Stable, high-performance, centrally managed networks became an ever more important part of our IT solutions.
The year also brought new energy to the team: several IT interns joined us, gained hands-on experience and brought fresh ideas and enthusiasm for modern technology.

2026
Our own data centre, cybersecurity and in-house AI
2026 is all about expanding our own IT infrastructure and the growing importance of IT security.
Expanding our data centre
Our own data centre infrastructure keeps growing. Several customers already rely on our systems to store their backups.
Expanding it further creates more room for reliable backup solutions, virtual servers and individually managed IT services.
Cybersecurity becomes our focus
As digitalisation grows, so do the demands on protecting company data and IT systems.
That is why in 2026 we are putting an even stronger focus on cybersecurity, network security, secure backup strategies and protection against cyberattacks.
We want to help our customers make their IT infrastructure more resilient and reduce the risks of data loss, malware and unauthorised access.
Our own artificial intelligence, right here in-house
Another important step is building out our own in-house AI infrastructure.
Our goal is to run more and more AI on our own servers, opening up new possibilities for smart automation, custom AI applications and privacy-conscious solutions.
We deliberately rely on our own infrastructure, more control over data and an implementation that is as independent as possible.

Our vision
Shaping tomorrow’s IT today
From our first IT services in 2022 to building our own server infrastructure, modern security solutions and artificial intelligence in 2026, we have followed one clear direction:
We don’t just want to manage IT, we want to actively move it forward.
We combine personal support and practical solutions with modern technology.
Our promise stays the same
