Antiy Labs Emergency Response Service is a professional cybersecurity service offering that encompasses three core areas: security configuration reinforcement, emergency response, and network security assurance. **Security Configuration Reinforcement** Covers hardening of five categories of systems: - Basic network equipment - Operating systems - Website applications - Database systems - Other applications **Emergency Response** Provides structured incident response to active security threats and outbreaks. The service operates with tiered response levels (e.g., "A – disaster response level") and includes activities such as threat analysis, warning issuance, distribution of protection manuals and patch packages, and release of immunization and scanning tools. A documented example is the WannaCry ransomware response in May 2017, during which Antiy detected large-scale propagation, issued in-depth analysis reports, published configuration guides, and released dedicated immunization and scanning tools within days of the outbreak. **Network Security Assurance** Provides security protection coverage for major events and critical infrastructure. Antiy holds designations as a national network security emergency service support unit of CNCERT, a member of the Information Notification Center under China's Ministry of Public Security, and a primary support unit of the China National Vulnerability Database of Information Security (CNNVD). Past engagements include security coverage for national-level events such as the Beijing Olympic Games, Expo 2010, and the Hangzhou G20 Summit.
