"It’s an incredible peace of mind to have these logs as insurance for this kind of situation. If I didn’t have this data I wouldn’t sleep well at night. I like to sleep well at night."

"For once, we weren’t chasing shadows. We saw the attack unfold in real-time…This exercise is a game-changer—it’s given us a playbook for future threats."

“Going into the PoC I’m not sure we appreciated the full value of what Corelight can offer. When we actually got to dig into the data and detections it was eye opening and a real wake up moment where we said: wow, ok so this is what is actually happening on the network!”

“Now, when we get an alert from our AV vendor, we routinely use Corelight logs to rapidly investigate the issue by pivoting from IP address, to device, to user, to source in a matter of minutes.”

“This deployment allows us to detect a malicious intruder in the very early phases of its attack before it attacks the endpoint, basically our SOC analysts shifted from a reactive mode thanks to Corelight to being proactive and having more time to do Threat Hunting.”

What is NDR?

Network detection and response (NDR) is a cybersecurity technology that continuously monitors network traffic from physical and cloud-based environments. NDR solutions include extended visibility, enriched network data, detection, threat hunting, forensics and response capabilities. These solutions are often delivered as a combination of physical, virtual, software, and cloud appliances. It enables security teams to more quickly detect adversary activity and respond to security incidents.

What is evidence-based security?

It is an approach that relies on a comprehensive and context-rich network data, serving as the single source of truth for all security operations. This high-fidelity evidence, built on the open-source Zeek standard, provides unparalleled breadth by capturing every connection (including from blind spots like East-West and encrypted traffic). Evidence helps accelerate SOC workflows and serves as an immutable historical record for threat hunting and compliance, while reducing false positives.

What is Corelight’s AI-powered security platform?

An AI-powered SOC leverages artificial intelligence and machine learning to enhance threat detection, streamline security operations, and create a more robust security ecosystem. This advanced approach moves beyond traditional, human-centric models to address the increasing volume and sophistication of cyber threats.

How can I reduce false positives?

Combating false positives requires a proactive approach to detection. Here's a practical checklist to help your team reduce noise and increase confidence in your security tools.

Implement a multi-layered detection strategy: Avoid over-reliance on a single type of detection. By combining different methodologies—like signature-based rules, behavioral analysis, and threat intelligence—you can create a more comprehensive security posture. This approach allows each detection method to compensate for the inherent gaps of another, increasing the overall confidence in an alert. When an alert is triggered by more than one independent detection method, its legitimacy is significantly higher.
Prioritize high-fidelity data: Move beyond low-fidelity sources like NetFlow and firewall logs. Invest in tools that provide rich, contextual network evidence like Zeek^® logs.
Tune your rules regularly: Continuously review and refine your detection rules and signatures. Regularly audit your most common alerts and suppress or adjust the rules that lead to false positives.
Use behavioral analysis: Supplement signature-based detections with machine learning and behavioral analysis. These methods can help identify anomalous activity that traditional rules might miss.
Establish a feedback loop: Create a streamlined process where analysts can easily provide feedback on false positives. This feedback is critical for informing detection engineering and rule tuning. To make this process more effective, ensure your team understands the value of red and purple team exercises for testing and validating your detection rules against real-world attack simulations.
Focus on detection engineering: Dedicate time and resources to creating custom detections tailored to your specific environment. This allows you to hunt for specific threats and reduce generic alerts.
Leverage contextual enrichment: Ensure your security tools are integrating with other sources (like threat intelligence, asset management, and user data) to provide a complete picture for every alert and correlation for higher confidence in alerts.
