Introducing: Dr. Andreas Koltes

We are delighted to welcome Dr. Andreas Koltes as the new Head of R&D and CTO of IHSE GmbH.

Andreas’ first goal and milestone as CTO will be the integration of kvm-tec and its KVM over IP products in the already existing IHSE portfolio of proprietary KVM solutions and as a result the merging of both product portfolios. With this integration he sets the course for the future of the entire KVM sector and helps to strengthen IHSE’s position as a global leader.

Before he joined IHSE he already gathered incredible expertise in a wide array of high-tech projects – from the drawing board stages to getting projects ready for serial production. This includes many years of experience with FPGA and networks technologies. In his previous position he was the head of “Embedded Systems Development” at DIEHL Defence and prior to that he worked as the technical lead in a German-American missiles project.

Andreas lives in the picturesque town of Überlingen, close to the IHSE headquarters at Lake Constance, and likes to spend time in the outdoors with his partner.

I am looking forward to working with the teams of IHSE and kvm-tec and am very excited about tackling future challenges and using my experience to facilitate IHSE’s “Road to IP”.

Dr. Andreas Koltes

We are happy to have Andreas on board and are looking forward to elevating KVM with him.

Draco tera firmware update 04.01

Feedback from our partners and customers is of utmost importance to us. It helps us to improve our products and is a great source for new product ideas and features.

With our latest firmware update, version 04.01, we released a number of enhancements, fixes and new features for all Draco tera enterprise and Draco tera flex KVM matrix switches. One new feature deserves to be highlighted a little more than the others.

 A well known, state-run Britsh television and broadcasting company approached us with a request to increase security in its many facilities. The company already has a substantial IHSE KVM network in place to streamline its workflows and enhance ergonomics and efficiency on premise.

They requested that access to workstations with CON units should be restricted to an exclusive list of operators, in order to increase security and minimize unauthorized access. Since we at IHSE pride ourselves on being “engineers who listen” we came up with a solution:

The feature is called Login-Lock.

Login-Lock will enable CON specific access for selected users. What it means is that a CON unit can only be accessed via a login function, asking for username and password, so that when this feature is activated, only eligible users are able to login to that unit. Therefore the Login-Lock function effectively restricts access and increases the security in the company’s facilities.

This feature was successfully released with our latest firmware update version 04.01. To get the new firmware and assistance in updating, please contact

Other new features of the new firmware version include:

  • Video Off: option to disable OSD 60 sec. after disconnecting, to allow the monitor going into power saving mode
  • Show Disconnect: option to display a little info box “Disconnected”, if no KVM connection is established
  • Primary Preferred: option to ensure always switching to the primary link upon being available (redundant setup only)

Java library: log4j

Java-Bibliothek log4j Sicherheitshinweis

Important Information concerning log4j.

On Saturday, the German Federal Office for Information Security (BSI) declared a “red alert”. The reason for this is a vulnerability in a common used Java library, called: log4j.
Due to this vulnerability, attackers could, for example, execute their software code on the affected servers and thus run malware on them.
The Draco tera Tool and Webtool of IHSE  are used for the configuration and administration of the KVM matrix switches Draco tera enterprise, Draco tera flex and Draco tera compact. Both tools are based on Java programming. They were checked immediately and are not affected by this issue, because the log4j library is not being used.

IHSE acquires kvm-tec

  • IT security specialist expands product portfolio
  • IHSE plans to drive growth with KVM-over-IP solutions
  • Addressing new customer groups and meeting growing demand for IP solutions

Frankfurt am Main/Oberteuringen/Tattendorf, November 3, 2021. IHSE GmbH (“IHSE”), a Brockhaus Technologies AG group company, acquired a majority stake in kvm-tec Holding GmbH (“kvm-tec”).

Founded in 2006, kvm-tec develops and distributes flexible, high-security KVM-over-IP solutions (KVMoIP) to extend and switch computer signals. The company enables the high-performance, latency-reduced transmission of the signals via the standard IP protocol in existing networks. IHSE is a leading global technology provider for KVM solutions (keyboard, video, mouse) via proprietary network protocols, and is expanding its product portfolio and customer base with this acquisition.

The proprietary KVM solutions of IT security specialist IHSE are used particularly in mission-critical applications such as air traffic control, in control rooms and in the utilities and transport sectors. KVM solutions over the standard IP protocol are increasingly being deployed in industrial applications, broadcasting, post-production and the public sector as the more flexible, lower-cost solution that can be implemented faster. With the acquisition of kvm-tec, IHSE is accessing a worldwide KVMoIP customer base which will benefit from the international IHSE distribution network going forward, with offices in Germany, the USA, Singapore and China. In addition to joint sales forces, the management of IHSE and kvm-tec see further synergy potential in purchasing and production.

Ing. Dietmar Pfurtscheller, founder and CEO of kvm-tec, will remain with the company after the transaction is completed, along with his wife Ingrid Pfurtscheller MSc, Head of Sales and Marketing, and drive growth together with the IHSE team. kvm-tec is based in Tattendorf, Austria, and currently has 28 employees.

“With kvm-tec’s IP-based product portfolio we are strengthening our strategic competitive position in the market for further growth. Now we offer the right KVM solution for every customer need. Our joint technology platform also means we are reinforcing our innovation capabilities in a rapidly changing market,” says Dr. Enno Littmann, CEO of IHSE. “Our international subsidiaries enable us to be close to our customers also. In the IT security space, local personal contacts are a key success factor,” adds Michael Spatny, Managing Director at IHSE.

“Since kvm-tec was founded some 15 years ago, we have continuously developed the technology behind our KVMoIP products and are proud to supply numerous international customers today,” says Ing. Dietmar Pfurtscheller, founder and CEO of kvm-tec. “We are confident that in IHSE we have found the right partner to support our ongoing growth; with its global footprint and KVM expertise we are well positioned to become a ‘KVM Global Powerhouse’ together,” adds Ingrid Pfurtscheller MSc, Head of Sales and Marketing at kvm-tec.

Marco Brockhaus, CEO of Brockhaus Technologies: “We are delighted that our technology group is continuing to grow with the acquisition of kvm-tec by IHSE. We make Mittelstand champions even better, even stronger, even more successful. Because that is exactly what Brockhaus Technologies stands for. We support our subsidiaries with our network and our expertise, and are a reliable partner for acquisitions too.”


Photovoltaic System

IHSE Firmengebäude mit Photovoltaikanlage

At the new site of IHSE GmbH in Oberteuringen, the opportunity was taken to install a powerful photovoltaic system in addition to a variety of environmental measures, such as a bee-friendly natural meadow and a biotope.

With a capacity of 99.36 kWp, the system has already made an enormous contribution to environmental protection in the period since its commissioning in 2019, effectively helping to avoid a total of 182t of CO2 emissions (by October 2021).

This is equivalent to the amount of 157 barrels of oil saved or 830g of nuclear waste avoided or 2 million kilometers of travel by ecar.

With this IHSE is supplying its company and employee cars directly with solar energy.


We are excited to contribute an important part to environmental protection.
