Security teams are drowning in point solutions. You’ve got your MDR service generating alerts, your NDR platform detecting network anomalies, and your SPM tools measuring security posture gaps. Three different dashboards, three different alert streams, and three different ways of thinking about security – but somehow threats still slip through the cracks.
The problem isn’t that these security functions don’t work. The problem is that they’re operating in isolation when modern attacks don’t respect those boundaries. Sophisticated threats exploit the gaps between endpoint monitoring, network detection, and posture management. The organizations that are winning against advanced threats have figured out how to unify these functions into comprehensive threat management programs.
Based on implementations with organizations running mature integrated security operations, here’s how to move beyond point solutions to unified threat management that actually reduces risk.
The Integration Imperative
Why Isolated Security Functions Fail
Traditional approach: Deploy best-of-breed solutions for different security domains and hope they work together.
Reality: Attackers exploit the coordination gaps between security functions:
- Endpoint compromises that aren’t detected until they cause network anomalies
- Network threats that bypass detection because endpoint context is missing
- Posture weaknesses that don’t trigger alerts until they’re actively exploited
- Attack campaigns that spread across multiple security domains without unified visibility
Example attack scenario: An attacker exploits a configuration weakness identified by SPM tools but not prioritized for remediation. The compromise bypasses endpoint detection because it uses legitimate administrative tools, and only triggers network detection after establishing persistent access and beginning data exfiltration. Each security function sees part of the attack, but none sees the complete picture.
The Unified Operations Advantage
When MDR, NDR, and SPM work together, security teams gain:
- Complete attack visibility from initial exploitation through impact
- Contextual threat prioritization based on actual risk exposure
- Coordinated response that addresses root causes, not just symptoms
- Predictive threat management that prevents attacks rather than just detecting them
