Hotmail – 4.5 out of 5 stars
Microsoft’s Hotmail e-mail service is the largest e-mail provider with 360 million registered users despite a 5% drop over the last 12 months, according to ComScore.
Microsoft just finished a major overhaul of its security efforts and feature offerings for Hotmail. The provider uses Secure Socket Layers (SSL), which makes the URL start with HTTPS and show a secured padlock in the browser to show the connection is encrypted. It just added full-session SSL that users can choose to either use HTTPS automatically or only for login and account update. It also offers two options because the automatic full-session SSL seems to cause problems with Windows Live Mail, Outlook Hotmail Connector, as well as Windows Live for Mobile and Nokia phones.
For password protection and recovery, Microsoft’s Hotmail now leads the way. With its update last July, Hotmail added the ability for users to request a one-time use password for unsecured computers or unencrypted Wi-Fi connections. It also allows users to confirm a phone number and e-mail address for password and account recovery.
Hotmail added a trusted sender icon system with its overhaul in mid-2010. A green shield is displayed next to confirmed email from hundreds of financial institutions and other companies.
Microsoft just announced that it has developed a system to isolate Javascript in e-mail. Before, most providers simply blocked Javascript because it was a common means of attack, but that also meant blocking legitimate Javascript applications like time-sensitive special offers. This move is huge for allowing users to safely experience dynamic content in their e-mails.
Bottom line: Hotmail may have played catch-up to Gmail in 2010, but they have roared back to take the top spot with innovation. With such a large user base, Hotmail always has a target on its back. But through a massive update in 2010, and continually adding security features, Hotmail has proven their dedication to security.
