As more security vendors provide cloud-based security as a service (SaaS), more small and midsize businesses consider these offerings. With vendors broadening their security offerings to include backup-and-restore, end-point monitoring messaging security and more, the appeal of one-stop security shopping in the cloud continues to grow. The best cloud security vendors are beginning to fulfill the promise of bringing enterprise-level security to SMBs. This is a trend that's likely to grow, and to grow quickly, especially with big security providers gobbling up both smaller specialty service companies. If you don't have dedicated security staff, now might be prime time to get your security head in the clouds.
