The DigiCert WildCard SSL Certificate provides 256-bit encryption with support for RSA and ECC algorithms, securing a domain and unlimited subdomains through organization validation. It includes a dynamic site seal, offers a $1,000,000 to $1,750,000 warranty, and ensures compatibility with over 99% of browsers and devices. The certificate is issued after business verification, typically within 2-3 business days, and comes with a 30-day refund policy. It does not support multiple domains but automatically secures new subdomains.
