Key takeaway
EDR and XDR are security technologies: EDR monitors endpoints, XDR correlates telemetry across endpoint, network, cloud, identity and email. MDR (Managed Detection and Response) is a managed service, the 24/7 human team that operates those tools, investigates alerts, hunts threats and contains attacks on your behalf.
EDR and XDR are tools
Endpoint Detection and Response (EDR) monitors laptops, servers and other endpoints, detecting suspicious behaviour and generating alerts. It needs skilled people to investigate and act on those alerts.
Extended Detection and Response (XDR) widens the lens, correlating telemetry across endpoints, network, cloud, identity and email in one platform to spot attacks that cross domains. It is still a technology that someone has to operate.
MDR is a managed service
Managed Detection and Response (MDR) is the human layer on top of EDR or XDR. A 24/7 Security Operations Centre validates alerts, hunts for threats, and contains attacks within agreed authorisation, isolating hosts, disabling accounts and blocking indicators.
The short version: EDR and XDR are tools, an MSSP forwards alerts, and MDR catches and stops the attack.
Which do you need?
It depends on whether you have a 24/7 team to run the technology.
- No in-house 24/7 SOC: MDR gives you the team and the outcome
- Have a SOC but want better cross-domain detection: add XDR
- Need endpoint visibility only: EDR may suffice, with people to action it
How IntelligenceX helps
IntelligenceX MDR provides 24/7 monitoring, threat hunting and managed containment with defined detection and response targets, enriched by DARKX dark-web intelligence and CSPMX cloud posture signals. We can run it on your existing EDR or deploy one for you.
Frequently asked questions
Is MDR better than EDR?
They are not alternatives. EDR is a tool; MDR is the 24/7 service that operates EDR or XDR for you. If you lack a round-the-clock security team, MDR delivers the outcome the tool alone cannot.
Do I still need EDR if I buy MDR?
You need detection tooling, but MDR providers can deploy and manage it, or run MDR on the EDR you already own, so you are not paying twice.
