With the robust development of the Internet, more and more companies have put their services online. While the Internet conveniences people’s lives, how to secure it becomes an increasingly severe challenge. Distributed denial-of-service (DDoS) is one of the most common types of cyberattacks. It paralyzes the target network, disrupts services, and causes direct financial damages by exhausting the egress bandwidth and degrading server performance. NSFOCUS’s anti-DDoS solution has been widely adopted by telecom carriers, financial companies, Internet service providers (ISPs), and small and medium-sized businesses (SMBs), which, in turn, makes it possible for the company to gain an insight in customer requirements, thoroughly understand various business scenarios, and keep innovating. In August 2017, NSFOCUS introduced an innovative concept of integrating BGP FlowSpec into ADS, injecting new life into DDoS protection.
