Protect logins, forms, payments, APIs, and multi-site access with HTTPS encryption, website authentication, and browser security locks, allowing users to submit information with confidence.
SSL certificates are used for website identity authentication and HTTPS encrypted transmission, and are suitable for official websites, membership systems, payment pages, API interfaces and multi-site businesses. After the certificate is enabled, users can reduce the risk of leakage and tampering through encrypted links when submitting accounts, orders, forms, and business data.
4 types of commonly used certificate solutions are selected for easy selection based on the number of domain names, whether wildcards are needed, and business credibility requirements.
