Leading engineering service provider in the automotive industry

Are you facing a similar challenge?

A leading global engineering service provider in the automotive industry turned to TEAL to consolidate and best secure an evolved Active Directory environment with two forests. The focus was on better integration of IT services and usability for the 6000 customer employees.

With the help of our assessment, we analyzed both forests for technical vulnerability or deviation from design recommendations. Requirements and goals were defined in workshops. The resulting packages of measures were prioritized by the customer and a roadmap for achieving the target was created.

TEAL supports the customer in securing and standardizing the Active Directory. Extensive information is also available in our blog series on the topic of (E)SAE.
Started approaches are consequently continued, which accelerate and optimize the implementation.

Internationaler Entwicklungspartner der Automobilindustrie

Are you facing a similar challenge?

A customer in the healthcare industry was operating in a relatively inhomogeneous security infrastructure world, which led to two challenges:

1. The security setup is not optimal and

2. employees, IT services could only be provided with difficulty, resulting in inconsistent service usage.

Together with the customer, an analysis of the current situation was carried out and guard rails as well as requirements for a new IT infrastructure were defined. In the further course, TEAL developed several target architectures and evaluation criteria for a management decision.

The customer has several options and evaluation criteria to decide how to make the IT infrastructure secure and efficient in the future.

International development partner of the automotive industry

Are you facing a similar challenge?

An internationally active development partner in the automotive industry for complex metal and hybrid structures with a large number of locations and more than 10,000 employees approached us to secure the complex and globally distributed infrastructure. In the course of security-relevant incidents in the said industry, TEAL was commissioned to check and secure the Active Directory infrastructure. TEAL was also commissioned to make preparations for the use of cloud services.

For this purpose, a detailed analysis of the customer’s security infrastructure was undertaken, risks were evaluated and weighted, and finally an action plan was proposed. TEAL was then commissioned to implement this plan. For this purpose, we designed a new security concept (TIER0), which we implemented with the customer in a cooperative atmosphere.

The security aspects of the customer infrastructure are thus conceptually re-implemented and secured, and at the same time prepared for the use of cloud services. This minimizes potential attack risks while at the same time future-proofing the core infrastructure.

Leading retail company

Are you facing a similar challenge?

The goal was to migrate the existing Groupwise infrastructure of a leading retail company (nearly 10,000 employees) with decentralized personal archives to Microsoft Exchange Online.

We supported the customer in project management as well as the selection of suitable technology partners, migration software and adaptation measures for end users. This also included establishing rollout support and integrating the local helpdesk.

The project we managed was already able to migrate 10,000 mailboxes within eight months. The migration of the personal archives to Exchange Online Archive also worked smoothly. In addition, an Office365 backup solution was introduced.

Company from the public sector

Are you facing a similar challenge?

After in-depth online research, a government agency approached us to analyze and secure their existing Active Directory infrastructure for full protection against cybersecurity attacks.

Due to the ever-increasing security awareness factor in the media, the customer wanted to restructure in this area and stabilize the basic pillars of infrastructure and identity management through external expertise.

In order to work out a suitable solution, we first carried out a three-day assessment in the customer’s environment to find out how possible attackers could get into the company’s network and how the customer could ideally protect itself against this. This resulted in a roadmap with recommendations and concrete implementation measures to effectively increase infrastructure security.

In further steps, implementation packages were derived, structured and prioritized. These packages were then implemented together with the customer. This included both organizational and technical measures and individualized concepts, which were adapted on the basis of the customer’s environment and other circumstances.

First, we started by establishing the common SAE basics. These include both the tiering concept and the introduction of PAW systems combined with consistent account separation. Extensive info is also available in our blog series on (E)SAE.

In the future, we will use the Enforce Suite to achieve extensive and permanent system hardening of the infrastructure as well as compliance with established hardening standards such as BSI or CIS.

International Manufacturing Company

Are you facing a similar challenge?

The goal was to harden and secure an existing Active Directory of an international company with 5,000 employees in the manufacturing industry according to SAE standards. In addition, PAWs were to be introduced for Tier 0 and Active Directory objects were to be assigned to the Tiers in order to implement all measures to make potential lateral movement more difficult.

In order to find a suitable solution, we first conducted a three-day assessment in the customer’s environment to determine how potential attackers could gain access to the company’s network and how the customer could effectively protect itself against them. The corresponding findings were then elaborated and evaluated by us. Our consultants were then able to implement these together with the operations team and carry out the process changes.

Meanwhile, the customer can administer its secured Active Directory structure through special secured PAWs (including multi-factor authentication) and has also established an encapsulated and hardened Tier0 environment.

IT service provider insurance –

Request fulfilment optimisation

ARE YOU FACING A SIMILAR CHALLENGE?

In order to be able to provide IT services to the specialist areas of the international insurance group with 40,000 employees faster, the company’s internal IT service provider set themselves the objective to accelerate the request fulfilment process and to reduce the error rate. The inconsistent service descriptions as well as the multiple media inconsistencies were identified as the source of the problems, complicating the co-operation with the external service provider who were fulfilling the process. By introducing a digital request fulfilment platform, these problems were to be solved.

TEAL supported the introduction of the request fulfilment platform based on ServiceNow (SaaS) substantially. We created the requirements analysis, developed a data protection and security concept and led the project management as well as the operational rollout.

The lead times of the orders were reduced significantly thanks to the new request fulfilment platform. TEAL facilitated the successful integration of the SaaS order platform into the existing landscape. This was successfully established as one of the first cloud solutions of the entire group.

IT service provider insurance –

Implementation of Linux

ARE YOU FACING A SIMILAR CHALLENGE?

As part of a major strategy program, the international insurance group with 40,000 employees restructured its IT portfolio. In the course of the restructuring, open source operating systems were largely to be provided by the internal IT service provider for the first time. As the company was, up to the strategy program, heavily relying on Microsoft-based operating systems and software, the portfolio of the infrastructure services, their management systems and the application development tools and processes had to be expanded.

TEAL assisted the client in selecting the open source platform (RedHat Enterprise Linux and CentOS) as well as choosing suitable management systems (RedHat Satellite, GIT, Jenkins and RedHat Identity Manager). The platform was supplemented with a Docker runtime environment based on Docker Swarm. TEAL also supported the architecture’s creation, development and integration. Additionally, TEAL also provided the project manager.

The IT service provider is now also able to offer open source software solutions to departments based. Through skilful integration, many synergies with the existing Microsoft systems and architectures could be used.

Globally active industrial group –

private cloud

ARE YOU FACING A SIMILAR CHALLENGE?

In order to be able to offer high-quality and cost-efficient IT services for its 15,000 employees worldwide, the Swiss industrial group launched a comprehensive modernisation program. The main objectives were to centralise IT operations and to implement a service-orientated operating structure. TEAL was given the task of consolidating and modernising the internal data centres. The data centres were to be designed as a private cloud infrastructure based on Microsoft virtualisation and management technologies to ensure maximum flexibility and cost efficiency.

TEAL accompanied the entire project from requirement analysis through design creation and implementation all the way through to acceptance. After it went live successfully, we temporarily controlled the operations team and supported service onboarding until the operation was successfully transferred to an offshore delivery centre.

Thanks to the co-operation with TEAL, the group was able to start productive operations of the private cloud within a few months. In the course of the co-operation, the client’s centralisation objectives were supported significantly through continuous expansion and improvement of the solutions.
