Your trust in us as Trusted Advisor for Infrastructure Security

has a color and a name TEAL

Teal is the blue-green color of the Eurasian green-winged teal duck and is considered a symbol of loyalty. Business philosopher Frederic Laloux introduced the term TEAL for organizational structures in his book “Reinventing Organizations”. Hierarchy is out, self-organization is in.


TEAL stands for a new way of managing companies by breaking down traditional corporate structures and creating space through loose structures so that everyone can develop their potential. Everyone is invited to participate in shaping the company.


TEAL Technology Consulting GmbH was founded in early 2017 by Manuel Hoffmann, Fabian Böhm and Alexander Schmitt. Many years of professional experience in a large, global consulting company with a focus on large customer projects with Microsoft technologies form the basis on which we are building our company.

Today the TEAL team consists of several highly specialized employees at the headquarters in Düsseldorf. The main focus of the consulting services for companies in Germany is the security of the Microsoft Active Directory through the Secure Administration Environment (SAE) and the infrastructure level through the Secure Core Infrastructure (SCI).


Our Secure Administration Environment (SAE) builds on Microsoft’s Enhanced Security Administration Environment (ESAE) and continues to evolve this design concept. This prevents attackers from penetrating your network and secures your entire infrastructure. TEAL is your trusted advisor for all your information security needs.

products & services

TEAL transforms: We no longer want to pass on our accumulated experience and know-how in the area of Microsoft infrastructure and Active Directory security exclusively in the form of project implementations, but as a provider of special solutions we want to continuously increase the security in customer environments. As a full managed service provider, we support you with highly efficient solutions. With these offerings, we consolidate our consulting portfolio and bring our own solutions to our customers.

No chance

for data thieves

Hackers today are highly professional. On average, a corporate network breach goes unnoticed for 170 days. 70 percent of attackers attempt to gain access to networks using stolen or fraudulent identities, then use lateral movement to obtain additional user credentials to gain access to highly privileged accounts.


Data theft costs German companies an average of 4.3 million euros and more: their reputation.


The reputational damage is often even greater than the material damage. Organizations are well advised to secure their IT infrastructure and educate their employees about potential threats such as social engineering and phishing.

Our Secure Administration Environment (SAE) delivery model is flexible and adapts to the customer’s maturity level.


With a fixed-price Active Directory assessment, we can empower your administrators, review your inventory, analyze your environment, and deliver quick wins. If you have already implemented initial measures, we can build on these and continue with targeted consulting.


IT security is a complex topic, which is why we emphasize regular training and education. We train your administrators and show you how SAE can help you manage your critical business systems.



Instead of a traditional waterfall model, we see the four phases of providing a secure administrative environment as a continuous process:



These are just a few of the best practices where TEAL has helped harden, protect and streamline customers’ systems and IT infrastructure.

  • Telco Group – Infrastructure modernisation

    In order to increase the customer functionality of the largest IP TV solution in Germany with nearly 2 million customers even further, the provider decided to implement a new version of the Microsoft IP TV solution.
