One of the oldest security sites in existence, Verisign offers a range of security certificates and the famous "Verisign Secured Seal" banner which alone they claim can increase visitor-to-sales conversions, lower shopping cart abandonment and result in larger average purchases. The company uses proprietary software which provides 128-256 bit encryption on transaction data such as credit card numbers. Securing more than 500,000 web servers worldwide and monitoring over 1.5 billion security events daily makes VeriSign a trusted authority. This particular trusted authority, however, can cost around $3000 to implement on your site and may not be a viable option for small-to-medium sized business.

Also offering SSL certificates, 256-bit encryption and a snazzy banner graphic, Thawte strives to ensure its customers that their visitors will have an authenticated, trustworthy site and that information is encrypted while in transit between web servers and browsers.

Like Verisign, Thawte is more appropriate for larger businesses.
