Microsoft technology, combined with a powerful DMS, offers businesses the opportunity to manage sensitive data securely, control processes efficiently and reliably comply with regulatory requirements.

Digital sovereignty is becoming increasingly important: according to a press release from the German digital association Bitkom, nearly two-thirds of German companies would grind to a halt without cloud services. However, the cloud also requires compliance with strict data protection regulations (e.g. the GDPR) and industry-specific compliance requirements.
In this respect, cloud sovereignty in Europe means that companies can store and process their data in a manner that complies with European regulations and data protection standards. Full control over one’s own data, a secure server location within the EU, and GDPR compliance are all crucial factors. This is important for companies because adhering to clear rules and laws ensures not only security in document management, but also protects customer and company data from third-party access.
Global regulations such as the US Cloud Act may conflict with the GDPR due to differing approaches to the protection of personal data. At the same time, establishing a clear governance structure is challenging. Without appropriate structures defining which security technologies are used and which access permissions are granted, companies risk compliance breaches, security vulnerabilities, and massive loss of trust.
Document Management Systems (DMS) help companies to manage information in a structured and centralised way. They streamline contract management by making documents easier to find and ensuring they are archived in an audit-proof manner. In invoice processing, OCR can be used to automatically capture and verify documents. At the same time, they support compliance, ensuring that legal requirements such as deadlines and data protection guidelines can be reliably met. Automated workflows, digital approvals and rapid access to documents and data also significantly boost productivity in day-to-day work.
Document management ensures that documents can be securely archived, transparently managed, and processed in a traceable manner at all times. The increasing demand for compliance and legally compliant processes is making functions such as audit trail security and comprehensive logging increasingly important. A DMS should therefore meet the following requirements:
Without a suitable DMS system, companies are taking risks. Documents can get lost in data collections, be filed incorrectly or go missing. This also increases the risk of unauthorised persons gaining access to this data. Compliance breaches are of particular concern as the incorrect storage of important data can have legal consequences if it does not comply with GDPR or GoBD regulations. Such breaches can lead to heavy fines and reputational damage.
Strict data protection laws and rising cyber threats can push organisations to their limits. The Microsoft Cloud addresses this challenge: with security standards, the Digital Resilience Commitment and comprehensive protection mechanisms, it provides a reliable foundation for managing sensitive data in compliance with the law.
The EU’s requirements for cloud and DMS solutions focus primarily on data protection and IT security. The GDPR stipulates that personal data must be archived in an audit-proof manner and processed in a transparent and traceable way at all times. Standards such as ISO 27001, encryption technologies and zero-trust models also strengthen IT compliance. Thanks to storage in European data centres and comprehensive audit capabilities, legal requirements can be reliably met, and evidence can be provided to supervisory authorities.
A clear security concept ensures that the cloud strategy is optimally secured and that all relevant aspects, such as access controls and data security, are taken into account. This includes hybrid cloud scenarios for data sovereignty, governance policies for access control, and regular backups and contingency plans. The concept should also consider interfaces with existing systems to ensure the DMS integrates seamlessly into business processes. Training is essential to ensure the security concept is implemented effectively. Furthermore, clear communication and reporting rules help to identify risks and ensure the secure use of the cloud.

Issues such as sovereign cloud, GDPR-compliant data management and long-term IT security are increasingly occupying businesses in Europe. In this interview, Patrick Carl, Director at Portal Systems, explains how Microsoft 365, Shareflex and Portal Systems can provide guidance and reliable solutions in this area.
Question: What is meant by a ‘sovereign cloud’ and why is this topic so crucial, particularly for companies in Europe?
Patrick Carl: ‘Sovereign’ does not mean doing everything yourself. That is neither possible nor sensible in today’s world. Rather, it means retaining control and making informed decisions. We have chosen to build on Microsoft’s offerings here because Microsoft provides an impressive range of solutions and invests heavily in meeting European requirements.
Question: How do DMS solutions based on Microsoft technology ensure strict EU requirements, such as the GDPR, are reliably met?
Patrick Carl: Here, Shareflex and M365 offer a wide range of tools to meet legal requirements. Secure and certified service providers and cloud infrastructures form the foundation. Shareflex adds structured and organised data and documents, combined with integrated access management. Retention and confidentiality classifications can further enhance this. This ensures that documents are stored in a legally compliant and audit-proof manner, and that information cannot be disclosed without authorisation.
Question: What advantages do companies gain by partnering with Portal Systems for implementation, particularly in terms of security, compliance, and long-term sustainability?
Patrick Carl: Microsoft is the wind that creates the waves. Shareflex is the surfboard for riding those waves. Consequently, our customers always benefit from the investments and capabilities of the Microsoft platform. Microsoft invests heavily in IT security and data protection. This also applies to documents managed in M365 using Shareflex. We are ISO 27001 certified ourselves and offer our services exclusively via Microsoft Azure. I am convinced that Microsoft will always provide the superior overall platform. Even if a competitor is ahead in certain niche areas, Microsoft can catch up. A good example of this is their close collaboration with OpenAI regarding artificial intelligence. It’s impressive how quickly they integrated this into their own products.
