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 and is considered a symbol of loyalty. The economic philosopher Frederic Laloux has 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 running a company in which conventional corporate structures are broken up and spaces are created by loose structures, so that everyone can unfold his potential. Everyone is invited to help shape the company.


TEAL Technology Consulting GmbH was founded at the beginning of 2017 by Manuel Hoffmann, Fabian Böhm and Alexander Schmitt. Many years of professional experience in a large, globally active consulting company with a focus on enterprise customer projects with Microsoft technologies forms the basis on which we build our company.

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


With our Secure Administration Environment (SAE), we build on the Microsoft Enhanced Security Administration Environment (ESAE) and are constantly expanding this design concept. This prevents attackers from spreading in your network and secures your entire infrastructure. TEAL is your Trusted Advisor for all questions concerning information security.

products & services

TEAL is transforming: 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 a project implementation, but as a provider of special solutions, we want to continuously increase security in customer environments. We support you with highly efficient solutions as a full managed service provider. With the offerings shown, we consolidate our consulting portfolio and bring our own solutions to our customers.

No chance

for data thieves

Hackers are highly professional today. A breach in a company‘s network remains unnoticed for 170 days on average. 70 percent of attackers try to gain access to networks with stolen or fraudulent identities, then obtain additional user credentials to gain access to highly privileged accounts via lateral movement.


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. Therefore, companies are well advised to secure their IT infrastructure and to warn their employees of possible dangers such as social engineering and phishing.

Our delivery model for a secure administrative environment or Secure Administration Environment (SAE), as we call it, adapts flexibly to the maturity level of the customer.


With an Active Directory Assessment at a fixed price, we provide your administrators with better know-how, sift through the inventory, analyse your environment and ensure the first “quick wins”. If you have already implemented initial measures, we can build on them and continue with selective consulting.


IT security is a complex topic, which is why we attach great importance to 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.

  • IT service provider insurance – Secure Global Authentication Platform (based on ESAE)

    The internationally active insurance group with 40,000 employees wants to improve cooperation between the individual Group companies and make greater use of global services.

  • Public data centre operator – Linux RPM build pipeline

    The development team of a public data centre operator in Austria couldn’t focus its full capacity on the development of new features and products because, with each new build, it had to carry out numerous manual steps until the packages were developed, tested and deployed.

  • 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.

  • Global pharmaceutical company – private cloud

    The global pharmaceutical company with over 40,000 employees faced the challenge of modernising its SharePoint-based intranet system while reducing operating costs for the platform and the hosted third-party web applications.
