What began as a small consulting engagement grew into a long-term strategic partnership between PATECCO and Bayer Business Services GmbH – the dedicated IT subsidiary of the global life sciences leader, Bayer AG. Bayer, with more than 150 years of innovation in healthcare and agriculture, relies on secure, scalable, and intelligent IT infrastructure to support its global operations. At the heart of this infrastructure is a complex Identity and Access Management (IAM) ecosystem – successfully managed and developed by PATECCO.
The Challenge
Bayer Business Services GmbH faced the challenge of managing a highly complex and expansive IAM environment. With nearly 300,000 user identities, over 420,000 groups, and approximately 60,000 roles, maintaining secure and compliant access across the organization was a mission-critical requirement. The challenge grew more complex with the need for:
- Tailored, individual programming to expand IAM functionality
- Numerous carve-outs and carve-ins due to global restructuring
- Seamless execution of Active Directory (AD) migration projects
- Integration of Privileged Access Management (PAM) and Customer Identity and Access Management (CIAM) systems
To meet these demands, Bayer needed more than a solution provider – it needed a strategic partner with deep IAM expertise and long-term operational capabilities.
The Solution
Over the course of more than 12 years, PATECCO became Bayer’s trusted IAM managed services provider, consistently delivering tailored solutions and proactive support that addressed the growing complexity of their identity management needs. From day one, PATECCO’s commitment to excellence was evident in every aspect of the collaboration:
- End-to-end IAM consulting and operations support
Providing continuous advisory and implementation support, right from project start-up to ongoing management. - 24/7 Managed Services for IAM infrastructure
Comprehensive monitoring and incident response ensured business continuity and system reliability. - Fixed-pricing model
PATECCO became the first IAM managed services provider to introduce a fixed monthly price model – giving Bayer transparency and cost control since 2015. - Annual recertification processes
All business-critical access rights were subject to mandatory yearly reviews to meet compliance and governance needs. - Flexible support options
A range of support models were provided under predictable pricing, tailored to Bayer’s evolving operational needs. - Certified supplier status
PATECCO achieved and maintained certification as a Bayer-approved IAM supplier, underscoring the quality and reliability of its service delivery.
The Results:
This long-term collaboration enabled Bayer Business Services to achieve transformative outcomes across all critical dimensions of identity and access management. By leveraging PATECCO’s deep technical expertise and strategic oversight, Bayer not only stabilized a highly complex IAM environment but also advanced it into a mature and compliant network. Key achievements include:
- Successful management of one of the largest and most complex IAM ecosystems in Europe

Together, they have not only met today’s IAM challenges, they have laid the groundwork for a more secure, scalable, and innovative tomorrow. The story of Bayer and PATECCO is more than an IAM provider-client relationship – it is a testament to what can be achieved through shared values, consistent delivery, and a deep commitment to security and operational excellence.
