It's a sign of the times. As more companies struggle to stay in business, and try to do more with less, they will continually gravitate to a managed-services model for their security needs. From a business perspective, outsourcing security tasks is affordable, reliable and efficient.
Instead of hiring, companies will increasingly rely on managed services for their basic security requirements, freeing up IT staff to work on other mission-critical projects. Plus, security as a service reduces house energy costs and requires less IT personnel resources -- which ultimately translates to fewer IT dollars spent. And not just for small businesses, although the bulk will be at the SMB and midtier levels. The SaaS model for security will become increasingly attractive for all types of businesses looking to cut costs -- which in this day and age is just about everyone.
