SANTA CLARA, Calif., August 28, 2026 – Gartner®, a global business and technology insight firm, recently published the Market Guide for Cloud Web Application and API Protection, in which NSFOCUS has been listed for the third consecutive year through its Web Application Firewall (NSFOCUS WAF). For NSFOCUS, this repeated inclusion reflects its comprehensive leadership across web threat protection, bot management, API security, and AI-native capabilities.
1. Web Protection: The Paradigm Shift from Rule Matching to Intelligent Defense
As web attack techniques grow increasingly sophisticated, traditional signature-based protection can no longer keep pace with zero-day vulnerabilities, polymorphic attacks, and encrypted traffic threats. NSFOCUS WAF has built a three-layer defense architecture that combines multi-engine collaboration, semantic analysis, and behavioral modeling:
Dual-engine detection architecture: Combining the high throughput of a regex engine with the high precision of a semantic analysis engine, it blocks known attacks at millisecond speed while using techniques such as SQL/NoSQL syntax tree parsing and XSS DOM tree reconstruction to precisely identify polymorphic payloads that attempt to bypass the WAF.
Full-traffic decryption inspection: Supporting real-time decryption and deep inspection of TLS 1.3 and national cryptographic standards SM2/SM3/SM4, it resolves the industry pain point of encryption creating a blind spot.
Whether against OWASP Top 10 threats or APT targeting business logic, NSFOCUS WAF delivers high detection rates with low false positives, building the first line of intelligent defense for enterprise web assets.
2. Bot Intent Analysis: From Identifying Machine Traffic to Understanding Attack Intent
Bot traffic now accounts for a large portion of all internet traffic, yet blocking all bots outright is neither realistic nor reasonable. Search engine crawlers and compliance monitoring probes must be distinguished from malicious credential-stuffing, promotion-abuse, and data-scraping bots. NSFOCUS WAF’s bot intent analysis engine makes the leap from identity recognition to intent assessment:
Core capabilities:
| Dimension | Technical Implementation | Value |
|---|---|---|
| Multi-dimensional fingerprinting | Combines JS challenges, device fingerprinting, TLS fingerprinting, and browser behavioral fingerprinting to build a “digital DNA” for each bot. | Precisely distinguishes humans from machines with >99.5% accuracy. |
| Intent behavioral modeling | Builds a bot behavior graph based on access paths, request frequency, parameter variation patterns, and business API call sequences. | Identifies “slow-rate attack” bots disguised as normal traffic. |
Typical application scenarios:
- Promotion abuse in e-commerce : Deploys bot protection in front of high-value endpoints such as flash sales, coupon claims, and raffles to precisely identify and block automated scripts and protect the interests of legitimate users.
- Credential stuffing and data exfiltration in financial APIs: Counters brute-force attacks on login endpoints and bulk scraping of sensitive data endpoints by using intent analysis to detect low-frequency, slow-rate covert attacks.
- Content tampering in government websites: Identifies automated vulnerability scanning against CMS backends and webshell-upload bots, cutting off supply chain attack paths.
3. A Future-Ready Protocol Stack: Full-Chain Proxy and Inspection for HTTP/2, WebSocket, and SSE
Modern web applications have evolved from a one-way request-response model into complex architecture featuring real-time bi-directional communication and streaming data push. NSFOCUS WAF is among the first to achieve end-to-end proxy and deep content inspection across the new-generation protocol stack:
01 HTTP/2 Full-Traffic Inspection
Protocol advantages: NSFOCUS WAF supports HTTP/2 multiplexing, header compression, and server push, improving transmission efficiency while enabling fine-grained inspection and policy control over every individual request within an HTTP/2 stream.
Application scenarios: Suited for enterprises using gRPC and microservice gateways, delivering the performance benefits of HTTP/2 without sacrificing security visibility.
02 WebSocket (WS/WSS) End-to-End Proxy
Technical breakthrough: NSFOCUS WAF breaks through the traditional WAF limitation of supporting only HTTP/1.1, achieving full lifecycle management of WebSocket connections, from the Upgrade handshake negotiation and frame-level traffic parsing to deep inspection and policy enforcement on message content.
Application scenarios:
- Online financial trading: Performs content auditing and sensitive data leak prevention on WSS-based real-time market data pushes and trading instructions.
- Collaboration platforms: Detects malicious scripts, phishing links, and sensitive file exfiltration transmitted over WebSocket channels.
- IoT management: Identifies anomalous command injection and firmware tampering attacks within long-lived device-to-cloud connections.
03 SSE (Server-Sent Events) Proxy Capability
Feature advantages: For Server-Sent Events, a unidirectional server push stream, NSFOCUS WAF delivers stream-level session persistence, content filtering, and sensitive data masking. In scenarios such as AI LLM applications, real-time data dashboards, and stock market feeds, it prevents SSE streams from being hijacked or exploited as covert data exfiltration channels.
4. Dual AI Engines: The Intelligent Brain Empowering Detection and Operations
NSFOCUS WAF deeply integrates AI capabilities into its core, building two key pillars: AI for Detection and AI for Operations:
AI for Detection: Leaving Unknown Threats No Place to Hide
Adaptive baseline learning: Uses unsupervised learning algorithms to automatically learn normal business traffic patterns and establish dynamic baselines. Any anomalous access that deviates from the baseline, whether a novel attack technique or abnormal insider activity, is flagged in real time.
Attack chain correlation: Uses graph neural networks to correlate and cluster security events scattered across WAF, API gateway, and bot management modules, reconstructing the full attack chain and advancing from isolated alerts to complete attack narratives.
Intelligent false-positive suppression: Uses NLP to parse business context and combines historical response feedback to continuously optimize detection models, reducing false-positive rates to industry-leading levels.
AI for Operations: From Hunting for Problems to Problems Finding You
Intelligent policy recommendation: Based on business traffic characteristics and industry compliance requirements, an AI assistant automatically generates WAF protection policy recommendations, lowering the technical barrier to security policy configuration.
Automated root-cause analysis: When access anomalies occur, the AI operations engine quickly distinguishes between attack-induced and configuration-change-induced causes and provides remediation recommendations, reducing MTTR (mean time to repair) by more than 80%.
5. Three Consecutive Years, a Milestone and a New Starting Point
Having been listed in the Gartner Cloud WAAP Market Guide for three consecutive years, NSFOCUS has demonstrated the resilience and innovation of Chinese security vendors in global competition. From web protection to bot management, from traditional HTTP to full protocol stack coverage of HTTP/2, WebSocket, and SSE, and from rule engines to an AI-native architecture, NSFOCUS WAF has always stood at the forefront of technological evolution.
In an era where AI is reshaping everything, NSFOCUS will continue to drive with the dual engines of intelligent detection and intelligent operations, building a future-ready web application and API security protection system for global enterprises, so that every web access is secure and trustworthy and every API call is auditable.
