ThreatBook  

ThreatBook was founded in 2015. In terms of products and technology, Xue Feng, founder and CEO of ThreatBook, put forward the concept of "New Threat, New Security", expanding the core basic detection technology of threat intelligence to the bottom layer of each product line, building a comprehensive threat detection and response technology stack that includes threat intelligence detection, machine learning, modeling algorithms and other technologies. it has upgraded traditional endpoint, IDS and gateway products and launched OneEDR (host/subscription-based threat detection and response product), TDP (flow detection and response product) and OneDNS (next-generation enterprise-class cloud-based gateway product).

Xue Feng said, "The comprehensive launch of multiple product lines is to assist government and enterprise users to achieve 'dynamic zero' of network threats. In the future, ThreatBook will continue to iterate and expand the current 'cloud management end' integrated security product matrix." Currently, ThreatBook's product matrix is early-integrated. Users with personal identities can use the X Intelligence Community to query cloud-based threat intelligence, use the S Cloud Sandbox to check file security, or use SHELLPUB to conduct free webshell checks, while users with a need for a deception-defense system can try the free community-based honeypot HFish; for government and enterprise users, ThreatBook uses threat intelligence-driven " Cloud+Flow+Endpoint" series of products help users build detection and response capabilities, and are equipped with a 7x24 security service team to protect users' emergency needs.

 In terms of business and service models, ThreatBook is one of the first vendors in China to try out a subscription-based model for security services, pioneering the concept of "security is service", advocating lightweight management in deployment, maintenance and implementation of products, using a subscription-based system for fees, and building an industry-leading customer success and security service mechanism. At the same time, in the face of the increasingly critical cyber security situation, ThreatBook can also help the country to establish a response system specifically for the defense of cyber warfare threats. 

At present, ThreatBook's products and services are widely recognized and have become an indispensable part of the industry's construction security operation system, with customers in government, energy, banking, securities, insurance, intelligent manufacturing, Internet and other fields and industries. ThreatBook already has nearly 1,000 large corporate clients such as STATE GRID Corporation of China, China National Petroleum Corporation, ICBC, China Merchants Bank, China Everbright Bank, CITIC Securities, China Life, Xiaomi, JingDong and CITIC Group.
