Automation of openvas is really best, It just take the IP and start the scanning.
Alien vault taking this product as in built in its features.
On the other hand multiple operating systems are supported by openvas. It is opensource based and free of cost as usual and use full to small business coverage.
It has been built to be an all-in-one scanner which is being updated or recurring basis, you can either select it manual or take a scheduled job on automatic basis. Overall this is really a good product and support many scanning engine in a single pane of glass. Review collected by and hosted on G2.com.
Its Input method is quit annoying for beginner users, secondly it could deep inspection as manually a person could do. on the web scanning some times it leave very basic vulnerabilities due to automation. and one thing I would like to add more about its scanning result its covering the less vulnerabilities as compare to other products.
