  • A U.S. government cybersecurity program was processing 50TB of Corelight data daily, relying on it for historical threat hunting. But massive data volumes made hunts slow and expensive, with Splunk queries taking nearly an hour to run. Using Corelight’s data aggregation feature, the team reduced logs by up to 90%, cut long-running queries by 70–80%, and lowered CPU usage by 35%—all without losing analytic depth or detection fidelity. The result? Faster threat analysis, significant cost savings, and the ability to expand monitoring to even more sites. 👉 Scroll through to see how Corelight helped this agency turn overwhelming data into efficient, actionable insight. 🔎 Learn more about Corelight’s approach to data aggregation: https://lnkd.in/eVYuvcdc

  • That’s a wrap on Black Hat USA 2025! 🎩 Thank you to everyone who stopped by booth #5433, joined our theater sessions, connected with us in the NOC, and shared insights on defending against advanced threats. This week reinforced what we see every day: network evidence gives defenders the clarity they need to uncover EDR-evasive activity and respond with confidence. Until next year, Black Hat! 📖 Learn more about our approach to network detection and response: https://lnkd.in/gBgsYyUC #BlackHat2025 #NDR #NetworkSecurity #ThreatDetection

  • EDR sees the endpoint. NDR sees everything else. Corelight and CrowdStrike are teaming up to show how integrated visibility across endpoint and network delivers faster detection, clearer investigations, and a more confident response. Backed by insights from the CrowdStrike's recent Global Threat Report, this webinar will explore how adversaries are escalating their tactics—and how the CrowdStrike Falcon platform and Corelight Open NDR can help shut them down. 🗓️ August 20 | 10am PT / 1pm ET 🔗 Register now: https://lnkd.in/eadswvTz #NDR #NetworkSecurity #ThreatDetection #EDR
