Tianrui International is a multinational company focusing on the cybersecurity industry, with our team members located in Taiwan, Japan, Singapore, and the Philippines. The Pangolin Smart Firewall is an independently developed and proprietary brand of Tianrui International, and is a cybersecurity device suitable for homes and small and medium-sized enterprises. It is capable of scanning network devices within the local area network, including mobile phones, tablets, personal computers, and other increasingly popular Internet of Things (IoT) devices, ensuring that devices within the local area network are protected from malware attacks, while also preventing users from having their personal data stolen by phishing websites. We hope to help people through our products so that, while enjoying the convenience of technology products, they can also protect their own data security and privacy from being stolen or misused by malicious actors, thereby further preventing cybercrime.
