Armis provides an agentless cybersecurity platform that identifies, monitors, and protects managed, unmanaged, and IoT devices across enterprise networks in real-time. Unlike traditional solutions requiring agent installation, Armis uses passive network monitoring and an AI-powered Asset Intelligence Engine to detect threats across the entire attack surface regardless of device type or operating system. The platform serves Fortune 100/500 companies and government entities, delivering comprehensive asset visibility and threat detection without the operational overhead of agent deployment.

Arctic Wolf delivers cloud-native managed detection and response (MDR) and security operations services through its AI-driven Aurora Platform, serving mid-market to enterprise organizations across endpoints, networks, cloud environments, and web applications. The company's Security Operations Graph processes over nine trillion telemetry events weekly, built on golden datasets curated by 1,000+ security experts over 14+ years, to detect ransomware, malware, and advanced threats without alert fatigue. Arctic Wolf's managed service delivery model differentiates it from point solutions—Concierge Security Teams provide 24/7 monitoring, automated remediation, and expert analysis aligned with customer business context. The company has established itself as the system-of-record platform in cybersecurity operations, serving 6,000+ customers globally.

eSentire is a cloud-native managed detection and response (MDR) platform that combines AI/ML with 24/7 human-led threat hunting to detect and contain cyber attacks in under 15 minutes. The company serves 2,000+ organizations across 80+ countries and 35 industries, with particular strength in financial services, legal, healthcare, and government. eSentire differentiates through its Atlas XDR platform, elite threat hunter access, and Threat Response Unit (TRU) for advanced incident investigation, complemented by digital forensics capabilities acquired through CyFIR.

Cato Networks delivers a cloud-native SASE (Secure Access Service Edge) platform that converges WAN and network security into a single unified service, eliminating the need for traditional MPLS and dispersed security stacks. Built on a globally distributed private backbone, the platform uses physical or virtual Cato Sockets at network edges to route and inspect traffic through Cato's cloud infrastructure with integrated security enforcement. The company serves 3,000+ enterprises including Carlsberg and TAG Heuer Porsche Formula E, replacing legacy on-premises architectures with a subscription-based, cloud-native alternative.

Cybereason is a cybersecurity platform combining EDR (Endpoint Detection and Response), XDR (Extended Detection and Response), and next-gen antivirus to detect and remediate threats across endpoints, servers, cloud workloads, and networks. Founded by Israeli Unit 8200 veterans, the platform uses behavioral analysis and cross-machine correlation to identify complex attacks with exceptional accuracy. The company has achieved perfect scores in MITRE ATT&CK evaluations and is trusted by Fortune 500 companies including Lockheed Martin. It differentiates through deep expertise in offensive cyber operations translated into defensive capabilities, enabling threat hunting and root cause analysis at scale.

Exein develops embedded runtime security that integrates directly into device firmware to detect and prevent threats in real-time at the kernel level. The platform uses eBPF-based observability and AI-driven behavior analysis to protect IoT, industrial, automotive, and aerospace devices without degrading performance or requiring hardware changes. Unlike traditional endpoint security that detects breaches after compromise, Exein blocks malicious execution paths before they can run, eliminating entire attack classes at the edge.

ExtraHop delivers a Network Detection and Response (NDR) platform called RevealX that applies cloud-scale AI to analyze petabytes of encrypted traffic daily across hybrid and multi-cloud environments. It combines NDR, network performance management, intrusion detection, and packet forensics in a single console to automatically discover devices, users, and applications while detecting threats and anomalies in real-time. The platform analyzes over 5,000 metrics and uses machine learning to baseline behavior and identify risks across all infrastructure and data-in-flight.

Claroty is an industrial cybersecurity platform that provides agentless, passive monitoring of OT, IoT, and IIoT assets across critical infrastructure environments. The platform integrates with existing security infrastructure to deliver visibility, threat detection, vulnerability management, and secure remote access without disrupting operational networks. Claroty's approach uses network traffic analysis rather than active scanning, making it the only practical solution for securing PLCs and SCADA systems that cannot tolerate downtime. The company serves Fortune 100 organizations in energy, manufacturing, pharmaceuticals, and other critical sectors.

Nord Security is an integrated cybersecurity platform providing VPN, password management, encrypted cloud storage, identity theft protection, and threat exposure management for both consumers and businesses. Founded in Lithuania in 2012 as NordVPN and formalized as an umbrella company in 2017, Nord Security operates a suite of interconnected security products including NordVPN, NordPass, NordLocker, NordLayer, NordProtect, NordStellar, and Saily. The company addresses fragmented digital security needs by offering enterprise-grade solutions that share consistent security standards across consumer and B2B segments. With $200M in funding and a $3B valuation as of September 2023, Nord Security serves millions globally through both freemium and premium tiers.
