EDR and XDR for modern threat defence

In today's rapidly evolving threat landscape, traditional security measures are no longer sufficient. As Digital Forensic Incident Response (DFIR) professionals, we've witnessed firsthand the limitations of perimeter-based security. The rise of sophisticated, multi-vector attacks demands a more sophisticated and proactive approach. That's where Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) software come into play.

The power of EDR

EDR has revolutionised endpoint security by providing real-time visibility and advanced threat detection capabilities. By continuously monitoring endpoint activity, EDR solutions can identify anomalous behaviours, suspicious processes, and potential Indicators Of Compromise (IOCs).

Expanding horizons with XDR

While EDR focuses on endpoints, XDR takes a broader approach by integrating security data from multiple sources, including network, cloud, and email. This unified view provides a more comprehensive understanding of the threat landscape.

Our team utilises XDR to:

• Correlate security events: XDR allows us to correlate security events across different domains, enabling us to identify complex, multi-stage attacks.
• Improve threat detection: By analysing data from multiple sources, XDR enhances our ability to detect advanced threats that may evade traditional security controls.
• Automate Incident Response: XDR automates IR workflows, allowing us to respond to threats more quickly and efficiently.
• Gain deeper context: XDR provides deeper context into security incidents, helping us understand the full scope of an attack and inform our decisions accordingly
• Breaking down silos: XDR lets us see how an attack moved through an environment, rather than just the endpoint it started on.

Partnering with SentinelOne

CCL recently partnered with SentinelOne, representing a real step-change in our capabilities: we can now deploy this powerful XDR to help our clients contain and remediate any threats to their systems.

We’ll be using SentinelOne to:

• Proactively threat hunt: We actively hunt for hidden threats by analysing endpoint telemetry, identifying patterns, and correlating events.
• Rapid Incident Response: We can now quickly isolate affected endpoints, contain threats, and minimise the impact of security incidents.
• Forensic analysis: We use XDR data to conduct detailed forensic investigations, reconstruct attack timelines, and identify the root cause of security breaches.
• Behavioural analysis: Understanding normal system behaviour allows us to quickly identify deviations that could indicate malicious activity.

What it all means for you

This represents a significant ramping up of our cyber security, IR and breach investigation offering. As experienced DFIR professionals, we understand the critical role that EDR and XDR play in modern threat defence and clients are now able to leverage a team that can:

• Effectively deploy SentinelOne to defend against attackers.
• Conduct thorough threat hunting and incident response investigations.
• Provide actionable insights and recommendations to improve your security posture.
• Maintain up to date knowledge on the current threat landscape.

EDR and XDR are essential tools in that endless fight to stay ahead of the evolving threat landscape and protect critical assets. And working with CCL and SentinelOne, organisations can gain the visibility, control, and response capabilities needed for robust defence and rapid remediation.
