Microsoft 365 Security

Protect identities, emails, company data and digital collaboration from modern cyberattacks – with integrated security mechanisms for your Microsoft 365 environment.

Code reflected in the glasses of an IT employee

Securing Microsoft 365 comprehensively.

Microsoft 365 is now the central work platform for many organisations – from email and collaboration to the storage of sensitive company data. At the same time, identities, permissions, external shares and cloud services create new attack surfaces. Many security features are already available but are often only partially used or not configured consistently. A holistic Microsoft 365 security concept combines identity protection, email security, data protection and continuous security monitoring into an integrated security architecture.

Challenges faced by our clients

Unclear permissions

User accounts, administrator rights and permissions are often expanded over the years without regular review. Outdated accounts or excessive permissions increase the risk of unauthorised access.

Phishing

Modern phishing, business email compromise and account takeover attacks increasingly bypass classic protection mechanisms. Without intelligent security features, the risk of compromised user accounts rises.

Inconsistent security policies

Security features are often only partially activated or configured differently. A lack of standards makes it difficult to consistently secure the entire Microsoft 365 environment.

Our approach

We develop Microsoft 365 security architectures that intelligently combine identity protection, email security, data protection, collaboration protection and security monitoring. Modern Microsoft security features are seamlessly integrated into existing security architectures and centrally managed. This creates a consistent level of security that reliably protects identities, communication, company data and digital workplaces.

Microsoft 365 is secure – but not automatically configured securely

Microsoft provides extensive security features for identities,
emails, devices and company data by default. However, your actual level of protection depends on how these features are configured, connected with one another and continuously monitored. Only the coordinated interplay of Microsoft Entra ID, Defender, Purview and zero trust principles creates a holistic security architecture for modern Microsoft 365 environments.

Central security building blocks

Microsoft Entra ID Protection

Protection of digital identities through multi-factor authentication, conditional access, risk-based access policies and continuous assessment of user and sign-in risks to prevent unauthorised access.

Conditional Access & Zero Trust

Dynamic access control based on user identity, device state, location, sign-in risk and security policies to implement modern zero trust security concepts.

Microsoft Defender for Office 365

Protection of Exchange Online, Microsoft Teams and SharePoint through Safe Links, Safe Attachments, anti-phishing policies as well as protection against business email compromise and zero-day threats.

Microsoft Defender XDR

Correlated detection, analysis and automated response to security incidents across identities, devices, emails, applications and cloud services for the rapid containment of complex attacks.

Microsoft Purview

Protection of sensitive company data through data classification, sensitivity labels, Data Loss Prevention (DLP), Information Protection as well as compliance and insider risk management.

Microsoft Secure Score & Security Monitoring

Continuous assessment of the Microsoft 365 security configuration, monitoring of security-relevant events as well as derivation of concrete optimisation measures for continuous improvement of the security level.

Typical protection areas

Identities & access

Protection of user accounts, administrators and privileged identities against account takeovers, unauthorised access and misuse through modern authentication and access concepts.

Email & communication

Defence against phishing, malware, business email compromise and other threats in Exchange Online, as well as protection of digital corporate communication.

Collaboration & files

Protection of Microsoft Teams, SharePoint and OneDrive including document sharing, external collaboration and secure data exchange.

Sensitive company data

Protection of confidential information through data classification, encryption, Data Loss Prevention (DLP) as well as controlled use and sharing of sensitive data.

Devices & compliance

Secure access to Microsoft 365 through managed devices, compliance policies and risk-based access control for stationary and mobile workplaces.

Security Monitoring

Continuous monitoring of security-relevant events as well as early detection, analysis and assessment of suspicious activities within the entire
Microsoft 365 environment.
