Highest Data Security for Your Cloud Architecture: Managed Microsoft Security Services

In 2020, attackers were even successful in 78 percent of all attacks.  By using cloud-based services such as Microsoft 365 and Microsoft Azure, you can counteract dangerous cyber attacks and benefit from new possibilities for securing your sensitive company data. We can help you take your security to the next level with intelligent tools like Microsoft 365 Defender and Azure Defender, and our Managed Microsoft Security Services.

Challenges Around Managing Your Cloud Security

The use of modern cloud technologies creates an area of tension for your IT security. Cloud services can be accessed via the Internet from anywhere and at any time - opening up space for various attack strategies. At the same time, they offer the opportunity to make the security of your data more comprehensive and effective than ever before. The challenge lies primarily in countering modern cyber attacks and recognizing new attack patterns in good time. Attackers are looking for ways to get into your corporate network and then attack from the inside. The inadequate or even lack of monitoring of your IT environment poses a major threat to the security of your sensitive data. A lack of know-how about necessary organizational measures also jeopardizes an efficient workflow.

Managed Microsoft Security Services – Individual and Highly Professional

To ensure the security of your entire IT environment, we at Arvato Systems consider security to be an integral component at all levels of your Modern Workplace. This is where our Managed Microsoft Security Services come in. Thanks to our Managed Microsoft Security Services, our specialists in the Security Operations Center (SOC) continuously monitor your entire infrastructure. In this way, we keep the secure score at a top level and enable the highest level of cyber security.


First, we configure the security solutions, from Microsoft 365 Defender or Azure Defender. We do this according to proven best practices. For customization, we configure the services individually based on your business requirements.

Managed SIEM

As part of Security Incident and Event Management (SIEM), we automatically correlate the collected event data from various sources. Our experienced specialists select the relevant rules from predefined regulations and optimize them. In this way, we automate the defense against threats (SOAR) in a targeted manner.


Among the approximately one million notables every day, there are a considerable number of false positives. As part of our Managed Detection and Response Services, we therefore decide whether the incident is critical. In the event of a threat, we deploy predefined measures to defend against it (incident response).

Need-Based Consulting for Your Cloud Security

Do you operate an in-house SOC and are unsure which services you need for comprehensive and reliable security in your cloud infrastructure? Or are you wondering which configurations of security services make sense in your company? As a package or independently of our Microsoft Managed Security Services, we offer you the right consulting service for your efficient Advanced Security. We show you modern security risks and explain to you which functions the security tools provide in this context.
