FireMon Rule Clean Up

Has this solution helped to clean up rules that had not been reviewed in several years? If yes, how many rules?

I called them once because I wanted to see if they had a report that I could run for rules that have not been used in 365 days. With their help, I was able to run that report and provide it to the network team so they could eliminate those rules that had not been hit in a year.

Another advantage is that is has helped to clean up rules that have not been reviewed in several years. There are thousands of rules every year that we clean up directly based off of the reports. To give more context to this answer, one of the main functions of anyone in security is: If we don't need it, we need to get rid of it. But there's always that battle between the needs of enforcing best practices and accommodating the business. Anyone who has ever used this solution, or competitors' solutions, or gone through a firewall cleanup process, has experienced this scenario: "Well, we deleted 300 rules and something broke and now we need to find out which of those rules we need to turn back on." And that happened because they were working from a report that they only ran once a month or once a quarter. What this tool allows me to do is not only disable unused rules, but to specify conditions like, "anything that is unused for at least six months, or at least a year." I can now put unused rules into different categories. Something hasn't been used in a year is very low risk. If it was used two months ago, there's a higher risk if I disable it. So it helps reduce potential impact, which is a unique feature.
