The whole antivirus market is completely different when it comes to home use and business use. As most companies I've encountered use Symantec Endpoint Protection because it's simple to use while having all the updates deployed across the network easy. The Malware Hub will mostly show tests for home use as it's easier to get that setup that way and most home users always would like to know what the best AV is.
Also comes down to what the business does and what they are trying to protect, i.e you're going to have heavy security settings on a school for example so the students do bring or browse anything bad and you want to make sure that the security side of the it infrustrucre is secure. If you were just a small business for example a business that sells Apples, you're not going to have as much security as the high end businesses.
