This is the cheapest Multi-domain SSL certificate and is perfect for MS Exchange. It is of a high quality and issued very quickly. The 128-bit certificate has perfect browser compatibility and can be received within three minutes. Each of the certificates has three domains but you can add additional ones for an extra cost – up to 2002 in fact. This is therefore a quick wait to get SSL certification for multiple domains. There is no paperwork necessary as it is just the domain that is being validated and so this speeds up the process. You will need to validate an email address and that just takes minutes. You will even get a free IDAuthority registration with each certificate. There is also professional support available from qualified staff. Each certificate is highly recognizable by browsers. The Comodo certificates work with 99.3% of browsers and you would normally have to pay a lot more to get this. You will also get a free seal that you can use on your site to inform your customers of the security that you have. Comodo has a great reputation for being a trustworthy company and so this will impress your customers.
