The EDR focuses on terminals. XDR correlates signals from multiple layers such as posts, identities, messaging, cloud and network.
In brief….The term XDR does not automatically guarantee better protection. Quality depends on the actually connected sources, correlation rules and the team that handles alerts.
Solution A.
EDR
The EDR analyses in depth the activity of computers and servers equipped with an agent.
Key points…
- Terminal Telemetry
- process and file
- Response actions on the post
Solution B.
XDR
The XDR aggregates and correlates several sources of security to rebuild a larger attack.
Key points…
- Cross-identities, e-mails and cloud
- Reduces isolated alerts by correlation
- Depends heavily on the integrations available
Comparative table….
| Criterion…. | EDR | XDR |
|---|---|---|
| Perimeter | Terminals | Several areas of security |
| Data | Agent Officer | Agents, API and connected services |
| Correlation | Posting | Transverse |
| Complexity | More targeted | Wider and more integrated |
Choose EDR if…
Your priority is the protection and investigation of the posts and servers.
Choose XDR if…
You have several compatible sources and want to track an attack through the identity, email, cloud and terminals.
Key takeaways
The term XDR does not automatically guarantee better protection. Quality depends on the actually connected sources, correlation rules and the team that handles alerts.
