Regulatory Compliance Monitoring
Compliance with industry regulations and standards is a critical concern for enterprises, and Defender for Identity plays a crucial role in this area. The solution continuously monitors user activities and access patterns to detect potential compliance violations, such as unauthorized access to sensitive data or suspicious privileged actions.
By providing detailed audit trails and compliance reporting capabilities, Defender for Identity helps organizations demonstrate their commitment to security and regulatory adherence. This is particularly valuable for enterprises operating in highly regulated industries, where the consequences of non-compliance can be severe.
Enterprise Identity Infrastructure
Azure Active Directory
Defender for Identity’s seamless integration with Azure Active Directory (Azure AD) is a key strength of the solution. Azure AD serves as the foundation for modern identity and access management, providing a comprehensive set of capabilities that enable secure access to cloud and on-premises resources.
Azure AD Identity Protection is a powerful feature that complements Defender for Identity’s threat detection capabilities. By analyzing user and entity behavior, the service can identify and respond to suspicious activities, such as compromised credentials or unusual login patterns, helping to safeguard your organization’s identities.
Azure AD Conditional Access, another integral component, allows you to enforce contextual access policies based on factors like user location, device health, and risk levels. This ensures that only authorized users can access sensitive resources, further strengthening your overall security posture.
Azure AD Identity Governance, on the other hand, empowers you to balance security and productivity by implementing robust access management processes. Features like entitlement management, access reviews, and privileged identity management help you ensure that the right people have the right access to the right resources.
On-Premises Identity Services
While Defender for Identity is a cloud-based solution, it seamlessly integrates with your on-premises identity infrastructure, leveraging your existing Active Directory investments.
