About
Virsec Systems is a cybersecurity company that provides Zero Trust Runtime Defense for server workloads — protecting applications and operating systems against ransomware, zero-day exploits, and supply chain attacks without relying on signatures, patches, or behavioral heuristics. Founded in 2014 and headquartered in San Jose, California, Virsec''s Virsec Security Platform (VSP) operates on a default-deny architecture: it creates a precise map of what code, processes, scripts, and libraries are trusted within a workload, then blocks anything that deviates from that trusted model at runtime — neutralizing attacks in milliseconds before they can execute malicious payloads.

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).
