What NSFOCUS does

NSFOCUS is a global cybersecurity vendor specializing in hybrid network security — combining on-premises appliances with cloud-delivered subscription services — for enterprise organizations, service providers, and critical infrastructure operators. Founded in 2000 by Jiye Shen and headquartered in Milpitas, California with regional subsidiaries across Singapore (APAC HQ), São Paulo (LATAM), Yokohama (Japan), Uxbridge (EMEA/UK), and Hong Kong/Macau (Greater China Region), the company sells a platform-plus-modules architecture anchored by three core products: the Anti-DDoS System (ADS) and Cloud DDoS Protection Service (Cloud DPS) for volumetric and application-layer attack mitigation; the Intelligent Security Operations Platform (ISOP), a consolidated XDR solution combining AISecOps and SOAR automation; and the Web Application Firewall (WAF) with semantic decoding-layer detection. Supporting modules include Network Detection and Response (NDR), Unified Threat Sensor (UTS), Next-Generation Firewall, NGIPS, Threat and Vulnerability Management, and Remote Security Assessment.

The company has built proprietary AI capabilities on top of this foundation, notably NSFGPT (a security-domain Large Language Model), AI-PTS (AI-powered penetration testing), AI-SCAN (specialized scanning for AI agent ecosystems including OpenClaw), and the AI LLM Risk Threat Matrix documenting 14 novel AI security risks. Threat intelligence is sourced from NSFOCUS Security Labs, founded in 2000, which operates honeypot/honeynet networks and maintains one of the world's largest vulnerability databases — research that feeds both product lines and external threat-report publications (2026 Cybersecurity Trend Report, 2026 Botnet Trend Report, 2025 APT Annual Landscape Report).

NSFOCUS generates revenue through a mix of subscription-based cloud services (Cloud DPS, Threat Intelligence, Continuous Threat Exposure Management), one-time product licenses for on-premises appliances (ADS, WAF, NGFW, NGIPS), and professional/managed security services. Go-to-market is primarily enterprise field sales with localized regional teams, supplemented by direct event engagement (RSA Conference, GovWare, CDIC), a thought-leadership content strategy, and a sales-led motion targeting verticals including electric power, telecommunications, financial services, government/military, and ISPs/MSPs. The parent entity is listed on the Shenzhen Stock Exchange (szse:300369) and the international operations are conducted through wholly-owned regional subsidiaries, with the US entity NSFOCUS, Inc. serving as the international headquarters.
