Modern endpoint security for MSPs must account for more than malware signatures or known virus patterns. Attackers frequently use fileless malware, credential compromise, living-off-the-land binaries (LOLBins), and lateral movement techniques that traditional antivirus cannot detect. This is where EDR (Endpoint Detection and Response) and XDR (Extended Detection and Response) become essential components of a modern security stack.
Why Traditional Antivirus is No Longer Enough
Small and mid-sized businesses are now primary ransomware targets. They often lack:
- Dedicated security analysts
- 24x7 monitoring capabilities
- Incident response maturity
- Formal security baselines
Traditional antivirus relies on static signatures, meaning it only detects known malware. Modern ransomware variants are polymorphic, meaning each execution can change its characteristics to evade conventional detection. This is one of the main reasons endpoint security for MSPs now standardizes around EDR and XDR.
What EDR and XDR Mean in Practical Terms
EDR is designed to recognize malicious behavior, such as:
- Rapid file encryption activity
- Unusual process spawning
- Unauthorized PowerShell execution
- Credential access anomalies
XDR expands this by correlating telemetry across multiple layers, enabling detection of coordinated or multi-stage attacks.
Key Capabilities in Endpoint Security for MSPs
Without EDR:
Ransomware executes, encrypts local and network data, and spreads before detection. The MSP is alerted only after systems are unavailable.
With EDR/XDR:
Anomalous encryption behavior triggers automated isolation. The system alerts the MSP, rolls back affected files, and prevents lateral movement.
Outcome:
Containment before operational disruption.
How EDR and XDR Relate to RMM
RMM platforms maintain operational integrity.
EDR/XDR platforms maintain security integrity.
When integrated:
- The RMM deploys and verifies the EDR/XDR agent
- The EDR/XDR detects and isolates threats
- The RMM executes remediation and recovery
This forms a closed-loop response system.
How They Complement Each Other
- Deployment and Coverage Assurance
RMM ensures agents are installed, active, and updated. - Detection and Automated Containment
EDR/XDR stops malicious behavior in real time. - Remediation and Recovery
RMM executes cleanup and applies configuration corrections. - Centralized Operational and Security Visibility
Reduced tool switching and faster decision-making, with monitoring, remediation, and device actions managed from the Level app. - Audit and Client Reporting
Stronger security posture justification during QBRs and renewals.

FAQ
What is EDR in cybersecurity?
EDR detects and responds to malicious activity at the endpoint using behavioral analysis and real-time containment.
How is XDR different from EDR?
XDR correlates telemetry across identity, email, cloud, and network layers to detect multi-step attacks that EDR alone may not see.
Can EDR/XDR replace an RMM platform?
No. RMM handles management and automation. EDR/XDR handles detection and response. They are complementary.
Conclusion
Modern endpoint security requires more than signature-based antivirus tools. MSPs must detect and respond to threats as they occur, especially as ransomware campaigns continue to target SMB organizations. EDR and XDR provide the behavioral analysis, automated containment, and response workflows necessary to prevent large-scale compromise.
When combined with an RMM platform:
- The RMM maintains operational stability
- The EDR/XDR stack enforces security integrity
- MSPs can deliver consistent, scalable, and resilient security outcomes
For MSPs modernizing their service offering, RMM plus EDR/XDR is now the standard architecture for endpoint security and operational efficiency.
