One of the best ways to get good advice about what security applications you should use to support a new system is to talk with your security service provider.
In many cases, the vendor will suggest you use the apps that are made by the company that created the hardware you are using, but the vendor can also offer key insight into what those applications are good at and where they may be weaker.
With this basic knowledge, you can look more closely at what you want to get out of your system and have a starting point for evaluating applications. By looking first at the applications suggested by your vendor, you can see specifically how they may meet your requirements and any areas where they are not up to the task. This information can be invaluable as you move out of those initial apps and start looking at more of the solutions that are available on the market.
By initiating the security app discussion with your system provider you can create a baseline upon which you can measure other solutions. As a result, it can be much easier to pare down the large and complex market to find the specific application you really need.
