We needed a file integrity and change track monitoring solution and initially looked at Tripwire. The problem was we weren't getting much response from our questions so started to look at alternatives.
We came across NNT and, to be honest, haven't looked back. We've built up a good relationship over the years, and support has always been first rate.
The really positive side is that whilst NNT have grown a lot since we started working everything still feels the same as it did all those years ago...very quick responses and still the same friendly people who were there at the start.
Very happy with our decision.
We were looking at this for Pci reasons and it solved a whole host of our compliance issues from monitoring change and file integrity to helping with hardening of server software installs. It's made life much easier, we get a daily automated email with events and alerts for unexpected changes.
