Cybersecurity cannot rely solely on reacting when the damage is already done. For years, many organisations have relied on a traditional SIEM-based SOC to centralise and correlate event logs. This model has been useful for detecting incidents, but it often falls short in one key area: prevention.
Analysts review alerts and escalate incidents, but they do not always have in-depth knowledge of the company’s environment or sufficient resources at critical times such as nights or weekends. The result: attacks are detected late and, in some cases, are not contained in time, putting business continuity at risk.
MDR: a paradigm shift in digital defence
Cybersecurity managed with MDR (Managed Detection and Response) breaks with the reactive model. It is not just a matter of observing and reporting, but of detecting, investigating and acting in real time, 24 hours a day, every day of the year.
This service ensures that your organisation always has an expert team monitoring and responding directly to the security solutions deployed. This avoids dependence on analysts without context or an outsourced CISO who only intervenes in critical situations.
The two pillars of proactive prevention
To move from reaction to prevention, MDR relies on two key factors:
1. Global view of the infrastructure
MDR is not limited to the endpoint. It can integrate information from the network, identities, email and cloud environments, creating a complete map of the digital ecosystem. This comprehensive visibility allows you to identify attacks that would otherwise go unnoticed.
2. XDR versus EDR
Traditional EDR only protects the device. In contrast, XDR (Extended Detection and Response) connects multiple sources of information and correlates data from different layers, allowing anomalous patterns to be detected and the chain of attack to be broken at a very early stage.
SOC vs MDR: the definitive comparison
| Aspect | Traditional SOC (SIEM) | MDR with XDR |
|---|---|---|
| Main function | Log collection and correlation | Continuous monitoring, detection and active response |
| Coverage | Limited to shifts (less effective at night and on weekends) | 24/7 with dedicated specialists |
| Result | High volume of alerts, many unresolved | Immediate and targeted action on the actual environment |
| Team | External analysts without detailed knowledge of the client | Specialised team with context of the environment |
| Approach | Reactive → responds after the incident | Proactive → anticipates and breaks the chain of attack |
Benefits of adopting MDR with XDR
- Reduced detection and response times: action in minutes, not hours.
- Real threat prevention: identifies patterns before the attack has an impact.
- Continuous protection: 24/7 coverage without relying on shifts or internal availability.
- Greater control and visibility of the digital ecosystem.
- Improved business continuity by minimising the risk of critical interruptions.
Practical conclusion
Adopting an MDR service with XDR capabilities is not just a technological upgrade: it is evolving towards a preventive cybersecurity model, where the organisation is permanently accompanied by specialists who ensure active protection against advanced threats.
