The best thing about this tool I think would be it's ability of tracking down vulnerabilities in our system without any downtime which makes us feel more secure as we need not worry if there will ever come an incident where data gets exposed or lost due to cyber-attacks.
There are many things one should look at before choosing such tools but with so much options available now finding something useful becomes difficult. It helps me track my entire business security from start till end using logs generated via various events like logon/off etc.,.
