The human element is one of the biggest core differences between EDR and MDR.
At-a-glance EDR vs MDR
| Category | EDR (Endpoint Detection & Response) | MDR (Managed Detection & Response) |
|---|
| Core model | Technology-driven | Technology + human expertise |
| Human element | Minimal (requires your team to interpret results) | Built-in (dedicated security analysts included) |
| Threat detection | Automated, within programmed parameters | Automated detection enhanced by human judgment |
| Endpoint isolation | Automated via AI and playbooks | Automated, confirmed and overseen by analysts |
| Threat response | Contains and neutralizes known threat patterns | Detects, isolates, neutralizes, and investigates |
| Investigation depth | Generates post-event report for your team to review | Analysts conduct in-depth investigation in real time |
| Root cause analysis | Your team's responsibility | Handled by the MDR security team |
| Next-step decisions | Your team interprets data and determines follow-up | MDR team assesses impact and recommends action |
| Adaptability | Limited to programmed parameters | Human experts adapt to unexpected or novel threats |
| Setup dependency | Effectiveness depends on correct configuration | Experts manage and validate configuration |
| Automation level | High | High plus human oversight layer |
| Best for | Teams with in-house security expertise | Teams that need expert coverage without hiring analysts |
EDR relies on sophisticated tech to precisely monitor, detect, and respond to threats. It scans your endpoints for anomalies and can neutralize threats as they appear.
Still, EDR can only operate within its programmed parameters. In other words, EDR’s effectiveness can be limited without expert oversight.
Meanwhile, MDR combines the tech of EDR with human expertise and instinct. These cybersecurity experts can interpret data, make real-time strategic decisions, and use their skills to adapt to unexpected challenges quickly.
Here’s how:
Let’s say a cybercriminal launches a phishing attack, tricking an employee to download a malicious file. An EDR solution would detect this activity, and using AI and playbooks, the infected endpoint would be isolated to stop the malware from spreading. From there, EDR would analyze the incident and generate a post-event report for your team to review. While this effective and automated process contains and neutralizes threats, your team still needs to interpret data, identify root causes, and follow up on the next steps.
That’s all assuming it was set up correctly in the first place. Otherwise, it will just alert you to the fact, and you'll still have to do the work outlined above—manually.
With MDR, the response goes a step further. The security team monitors endpoints with EDR, but when the same phishing attack happens, not only does the team detect the activity, isolate the endpoint, and neutralize the threat, it also launches an in-depth investigation. The human experts analyze, assess the potential impact, and decide on your next steps in real time.
So, while EDR automates threat detection and containment, MDR adds expert oversight to address threats with intelligence, adaptability, and strategic precision.
