About
Corelight is a cybersecurity company founded in 2013 by Vern Paxson, Robin Sommer, and Seth Hall and headquartered in San Francisco, California. The company commercializes and extends Zeek (formerly known as Bro), an open-source network analysis framework developed by co-founder Vern Paxson at Lawrence Berkeley National Laboratory that has become the de facto standard for high-fidelity network traffic analysis in enterprise and government security operations. Corelight's platform provides network detection and response (NDR) capabilities — deep packet inspection, protocol parsing, and threat detection across network traffic — giving security teams comprehensive visibility into what is moving across their networks, which is critical for detecting threats that evade endpoint-based tools.

About
Palo Alto Networks, Inc. is a Santa Clara, California-based cybersecurity platform company — publicly traded on the NASDAQ (NASDAQ: PANW) as an S&P 500 Information Technology component — providing network security, cloud security, and AI-driven security operations through three integrated security platforms: Strata (network security — next-generation firewalls, SD-WAN, Zero Trust Network Access), Prisma Cloud (cloud security posture management, cloud workload protection, CSPM/CWPP), and Cortex (AI-driven security operations — XSIAM extended security intelligence and automation management, XDR endpoint detection and response, XSOAR security orchestration) through approximately 15,000 employees worldwide. In fiscal year 2024 (ending July 2024), Palo Alto Networks reported revenues of $8.0 billion (+16% year-over-year), with next-generation security Annual Recurring Revenue (ARR — Prisma Cloud and Cortex subscriptions) growing 42% to $4.2 billion as large enterprise and government customers consolidated security toolsets onto Palo Alto Networks' platform versus maintaining dozens of point solution security vendors. CEO Nikesh Arora (joined 2018 from SoftBank as Chairman and CEO) has executed the "platformization" strategy — convincing large enterprise security buyers to replace 10-15 individual security vendors (email security, endpoint protection, cloud workload protection, network detection) with a consolidated Palo Alto Networks platform contract that provides 80% of point-solution capabilities at 50% of the total cost — using the first-year transition economics to accelerate platform adoption through deferred commitment offers (paying a lower platform price in year 1 in exchange for multi-year platform commitment in years 2-4).
