ExtraHop helps enterprises detect and respond to network threats using AI-powered traffic analysis.
Venture Round $162M total Founded 2007 Seattle, Washington 662 employees
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.
Problem solved
Security teams lack real-time visibility into encrypted network traffic and lack the ability to detect behavioral anomalies and threats across complex hybrid and multi-cloud environments.
Target customer
Enterprise security teams managing hybrid and multi-cloud infrastructure, particularly financial services, healthcare, retail, and government organizations requiring real-time threat detection and network visibility.

Competitors
Darktrace
Uses AI for cyber defense and network threat detection, but less focused on the integrated NPM and packet forensics capabilities ExtraHop provides.
Vectra AI
Offers AI-driven XDR platform integrating network, identity, cloud, and SaaS, but ExtraHop specializes specifically in network detection and response with native line-rate decryption.
Stamus Networks
Focuses on network security with threat detection, but lacks ExtraHop's integrated network performance management and scale of AI-driven behavioral analysis.
Attivo Networks
Focuses on deception technology and threat detection, but doesn't offer the comprehensive network performance management and encrypted traffic analysis ExtraHop provides.
Lumu
Provides threat detection but lacks ExtraHop's integrated network performance management and comprehensive device and application discovery capabilities.
Why this matters: ExtraHop is a leader in the growing NDR market (Gartner Magic Quadrant 2025, IDC MarketScape 2024) that combines multiple security and performance functions into a unified platform. With $162M in funding including a $900M growth equity round and ~$200M ARR, the company is well-positioned in the critical intersection of network security, threat detection, and infrastructure visibility that enterprises increasingly require for hybrid and multi-cloud environments.
Best for: Large enterprises and critical infrastructure organizations needing real-time visibility into encrypted network traffic and AI-powered threat detection across hybrid and multi-cloud environments.
Use cases
Detecting encrypted malware and lateral movement
Security teams use ExtraHop to identify malicious activity within encrypted traffic that traditional firewalls cannot inspect. The platform's behavioral analysis detects anomalous PowerShell execution and command-and-control communications even when encrypted, enabling faster threat response.
Troubleshooting application performance issues
Network operations teams use RevealX's integrated NPM capabilities to rapidly identify the root cause of application slowdowns by analyzing transaction-level metrics across thousands of applications and devices, reducing MTTR from hours to minutes.
Discovering shadow IT and rogue devices
Security teams automatically discover and profile every connected device, application, and user without requiring instrumentation, enabling faster identification of unauthorized workloads and IoT devices in the network.
Compliance and forensic investigation
Organizations use the platform's packet forensics and comprehensive network transaction analysis to support security investigations, forensic analysis, and compliance audits by providing detailed evidence of network activity and data flows.
Alternatives
Suricata Open-source IDS/IPS focused on intrusion detection but lacks AI-powered behavioral analysis, cloud-scale processing, and integrated network performance management.
Zeek Open-source network security monitoring tool offering network analysis but without AI-driven threat detection, encrypted traffic analysis, or integrated incident response capabilities.
Cisco Tetration Provides application dependency mapping and microsegmentation but is less focused on real-time threat detection and behavioral anomaly detection compared to ExtraHop's NDR approach.
FAQ
What does ExtraHop do? +
ExtraHop is a Network Detection and Response (NDR) platform that uses cloud-scale AI to analyze encrypted network traffic in real-time, automatically discovering devices and applications while detecting threats and behavioral anomalies. It combines threat detection, network performance management, and packet forensics in a single integrated console for visibility across hybrid and multi-cloud environments.
How much does ExtraHop cost? +
ExtraHop uses module-based licensing with pricing dependent on device count bands and sensor appliance network capacity. Specific pricing is not publicly available; organizations must contact the sales team for custom quotes based on their infrastructure scale and requirements.
What are alternatives to ExtraHop? +
Alternatives include Darktrace (AI-powered network threat detection), Vectra AI (AI-driven extended detection and response), Stamus Networks (network security monitoring), and open-source options like Suricata and Zeek, though these typically lack ExtraHop's integrated capabilities and AI-scale.
Who uses ExtraHop? +
Enterprise security and network operations teams across financial services, healthcare, retail, and government sectors. Notable customers include Home Depot, Ulta Beauty, Seattle Children's Hospital, and the City of Dallas.
How does ExtraHop compare to Darktrace? +
Both use AI for cyber threat detection, but ExtraHop specializes in network detection and response with integrated network performance management and packet forensics, while Darktrace focuses more broadly on cyber defense across endpoints and networks. ExtraHop's line-rate decryption capabilities and behavioral baselining across 5,000+ metrics provide deeper network-specific threat intelligence.
