I like that Flexential does a great job of building out the various compliance requirements for an organization. I like that they are able to look at the needs of an organization and help tailor a specific plan to meet those needs. You can find a lot of vendors that will provide a canned plan, but Flexential really takes the time to understand the needs of an organization. They are also very easy to work with. I've used Flexential for a variety of compliance projects, and they have always been able to deliver on time and within budget.
