The software performs an audit of all running services using several common sources so it runs quickly in comparison with other scanners which use multiple different scan techniques (such as signature checking or port scanning).
All ports are reported if open but you need some manual intervention otherwise - just configure your own lists! If this includes any application servers then make sure they're up-to date too; I found my Tomcat was out-of-date from at least 10 years even though we had no previous evidence there were vulnerabilities against our codebase because only two people used tomcats directly compared others who did webservice stuff via spring/java etc.. The GUI makes it very easy in finding vulnerabilities compared with other tools I've used before such as Nessus or OpenVAS which are more complicated than this tool (as far easier). If you're looking into an open source product then definitely give lynx enterprise another look! Not much at all - just make sure your requirements match what they have available/offered so there's no compatibility issue later downthe line when upgrading versions of software etc..
