This is a really crowded space - there are a lot of small business offering 'managed' vulnerability scans, so you will struggle to differentiate yourself. Having said that, you seem to be a good job of differentiating yourself in a rather bad way from those other businesses:
Most other businesses tell you what vulnerability scanner(s) they use.
Most other businesses offer a free scan (or partial scan), so you can get an idea of what is provided.
Most other businesss show sample reports, so you can get an idea of what is provided.
Dammit, every other business tells you something useful about the product being offered, and absolutely tell you who is offering it.
I'm sorry if this is all negative, but... come on?! This honestly looks like some chancer has thrown this up in their lunch break. There isn't even anything to tell me who 'ScannerSec' is - I seriously can't even tell if this is some kind of scam to extort HN users.
