It's simple to use, it can be integrated with other applications such as Slack so you could have alerts sent out directly from your slack channel or emails etc.
The reports are also very good for tracking vulnerabilities in all of our servers - whether they're managed by us ourselves (which we do) or not! I would like some more customisation options available within hackvity itself but this isn't something i've had any problems with at present. We manage around 100+ nodes/servers each being checked regularly using different methods which means about 10-20 tickets per week need monitoring throughout various time zones depending how busy things get during certain times in year e.g summer vs winter months when there will likely be less people checking their systems than usual due to holidays / staff leave etc.
