Manages network threats and supports application control with ease
The best advantage of F5 Silverline Managed Services is that it is easy to use. The admin guide they provide is easy to understand and allows for implementation within a few days. The traffic manager and the monitoring tool are valuable as well. The monitoring tab displays GET and POST requests in a readable format, making it accessible even to non-tech-savvy individuals. It offers effective reports and monitoring capabilities.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.
