About StopDDoS
StopDDoS, registered as Zhejiang Yunyun Cloud Computing, was a Taizhou-based entity founded in 2017 that provided cloud application security solutions before ceasing operations. The company secured $20 million in a Series A funding round in 2018, which was its sole funding event. The firm's objective was to offer a comprehensive security solution for websites.
The core of its business was centered on protecting web assets from a variety of cyber threats. It served clients in need of robust online security. The business model involved providing a suite of security products designed to defend against malicious traffic and online attacks, though specific pricing or subscription details are not publicly available.
StopDDoS's product portfolio included an Anti-D Cloud Web Application Firewall (WAF), the Yun Yu Game Shield, an anti-DDoS high-defense IP service, high-defense servers, and anti-hijacking SSL certificates. The Anti-D Cloud WAF was a notable product, utilizing a cloud-based FPGA chip-level engine. This system was engineered to defend against various Layer 3, Layer 4, and Layer 7 DDoS attacks by employing multiple recognition and cleaning algorithms. Furthermore, it integrated real-time threat intelligence and user behavior analysis to rapidly distinguish between legitimate and malicious traffic, while its anti-hijacking SSL certificates aimed to enhance website credibility and prevent data sniffing.
