Toward a Proactive Approach to Site Security
For CIOs and CISOs in the industrial sector, digital risk management has evolved. Today, the goal is no longer simply to erect barriers, but to ensure service continuity under all circumstances. With this focus on resilience, ANSSI (the French National Cybersecurity Agency) recommends the integration of EDR (Endpoint Detection & Response) solutions) solutions.
Far from being just another tool, EDR is part of a modern defense strategy , particularly relevant for companies that must comply with the requirements of the NIS2 Directive.
Going Beyond the Limits of Traditional Protection
Traditional antivirus software (EPP) remains a useful first line of defense against known threats. However, we advise our clients to be prepared for more stealthy intrusion methods that bypass these static signatures.
The Challenge of Visibility: Without behavioral detection, an anomaly may go unnoticed on your endpoints (workstations and servers). EDR helps transform this blind spot into a management tool:
- Understanding Rather Than Suffering: Where antivirus software blocks threats without explanation, EDR documents the progression of an event.
- Maintaining Production: By precisely identifying the source of unusual behavior, you can avoid widespread, untargeted shutdowns that hinder your industrial operations.
- Optimizing Response Time: Responsiveness is the key factor in minimizing the operational impact of an incident.
Without EDR, an intrusion can go undetected for several months (dwell time). For an industrial facility, this isn’t just a risk of data theft—it’s a ticking time bomb that threatens the integrity of your production controllers. Technical blindness is the highest cost of your cybersecurity.
The Benefits of Assisted Remediation
ANSSI highlights and recommends EDR for its ability to facilitate “remediation.” For a systems security manager, this means having tools capable of:
- Surgical isolation: If a workstation poses a risk, it can be logically isolated from the network without interrupting the entire production line.
- Analyzing the History (Forensics): EDR acts as a black box, enabling your experts to understand the root causes of an incident and strengthen your defenses for the long term.
- Automate simple responses: To allow your teams to focus on high-value tasks, the tool automatically handles common threats according to your security policy.
Sovereignty and Performance: The HarfangLab Choice
In our consulting work, we prioritize solutions that respect the integrity of your data and the performance of your business applications. That is why Scalair has chosen HarfangLab, a French solution certified and approved by ANSSI.
- Minimal footprint: The HarfangLab agent is designed to be transparent to the user and the infrastructure (CPU usage of approximately 1%), which is essential for production servers.
- Privacy and Compliance: By choosing a sovereign provider, you ensure that your telemetry data remains under French jurisdiction, thereby simplifying your GDPR compliance and protecting your trade secrets.
Unlike U.S. solutions subject to the Cloud Act, HarfangLab guarantees complete immunity from non-European legislation. The protection of your trade secrets is at stake here.
The Managed Model: Scalair’s Expertise at Your Side
EDR is a powerful tool, but its full effectiveness depends on the human expertise that drives it. For many mid-sized companies, maintaining 24-hour monitoring in-house poses a major organizational challenge.
Scalair’s “operational” approach: As your partner, we don’t just deploy a license. We manage your security through our MDR (Managed Detection & Response) service:
- Analysis and Qualification: Our SOC (Security Operations Center) filters alerts so that we only notify you of actual, verified incidents.
- Proactive Support: We help you adapt your security policies to keep pace with evolving risks specific to your industry.
- Operational peace of mind: You delegate technical monitoring to specialists so you can refocus on steering your digital transformation.
