Readers gave Check Point's VPN-1 UTM, formerly known as Express CL, high marks for the depth of security it provides and its form factor. But there's plenty to be said for the company's stability as a security vendor.

VPN-1 UTM offers firewall, intrusion prevention, anti-virus, antispyware, Web application firewall, and both IPsec and SSL VPN, within a single integrated platform. All these functions can be centrally controlled and updated in real time.
