Key questions you should be asking

Is vulnerability management critical for a business? Aren’t traditional security tools sufficient to protect and secure the network? Yes, to the first question and a resounding no, to the second!

Managing a large and growing PC estate is no simple matter, particularly if you are doing it manually.

But what happens when your estate grows beyond one or two machines?

Patch management:

Managing and administering software updates remains one of the most challenging and resource-intensive tasks an IT department undertakes on a daily basis. This white paper examines the important role played by patch management to help organizations keep their PC real estate fully up-to-date with the latest security patches, without unduly compromising reliability, productivity, security and data integrity.
