We are having our web application distributed across a number of subdomains on our hosting account. We want a single SSL certificate solution for our web application?

A special type of SSL certificate known as a 'Wildcard' certificate caters specifically for services distributed across a number of sub domains. RapidSSL wildcard and Business ID wildcard from Geotrust at an economical price with great pricing options are good solutions to your wildcard certificate needs. Getting them for your subdomains will be a good way to secure communications.
