Efficient threat management across Microsoft Defender
Simplify security workflows while ensuring strong threat management and compliance
A large government organization faced significant challenges in managing Microsoft Defender at scale. Operating across multiple departments and agencies, each with distinct security needs and operational priorities, the organization needed a solution to streamline security operations while maintaining robust threat management and compliance.
The challenge
Managing security threats in a dynamic, multi-unit environment
The government relied heavily on Microsoft Defender to detect, investigate, and respond to security threats across a range of topics, including applications and end points, plus Office and Teams collaboration. However, with thousands of users and devices spread across multiple agencies, managing security incidents through a centralized approach created numerous challenges.
The organization needed a solution to distribute security responsibilities, optimize workflows, and ensure quicker threat resolution without compromising security oversight.
Limited role-based access
A small central security operations (SecOps) team held global admin access, with much of the work undertaken on privileged access workstations, making it difficult to delegate tasks efficiently while maintaining visibility and control.
Slow incident response
High-priority threats were often delayed as the SecOps team faced backlogs in reviewing and acting on quarantine items.
Lack of segmentation
Without granular access controls, agencies couldn’t independently manage low- and medium-priority incidents, resulting in bottlenecks.
Poor user experience
False positives and low-priority incidents overwhelmed the SecOps team, leading to frustration and slower threat resolution.
Inefficient workflows
Security data was siloed, making collaboration and visibility across departments challenging.
The solution
VOSS for agile, role-based Defender management
To address these challenges, the government deployed VOSS to enhance the management of Microsoft Defender. By providing intelligent automation, proactive monitoring, and role-based access control, VOSS empowered local teams to manage their own security incidents while maintaining centralized oversight.
The benefits
Faster response times and improved operational efficiency
By implementing VOSS, the government organization achieved tangible improvements across its security management operations:
Enhanced visibility
SecOps maintained a global view of security incidents while gaining deeper insights into agency-level activity.
Localized control
Agencies could resolve incidents independently, reducing pressure on the central team and speeding up threat response.
Operational efficiency
Automated workflows minimized manual tasks, improving accuracy and reducing response times.
Improved user experience
Quicker incident resolution reduced disruption for end-users and built confidence in security operations.
Stronger security posture
By streamlining workflows and enabling real-time threat management, the organization minimized security risks and ensured compliance.
With VOSS, the government organization redefined its Microsoft Defender management strategy. By empowering agencies to act swiftly while maintaining centralized oversight, they achieved a scalable, secure, and efficient solution for threat management.
Addressing a growing security challenge
As cyber threats evolve, managing Microsoft Defender at scale becomes increasingly complex. VOSS provides the tools to segment large, multi-unit environments, streamline security operations, and ensure visibility across all levels of the organization. By automating key security workflows, delegating control with precision, and enabling proactive threat management, VOSS helps organizations strengthen their cybersecurity posture while reducing operational overhead.
