"You can become a penetration tester at home by testing your own server and later make a career out of it."
Sounds like the old style correspondence school ads - a bit hokey.
I would have rewritten that as:
"Many people have actually made a career out of being a penetration tester by first testing their own home server"
My comment strictly related to the style of what they were saying (and how I might rewrite that) I think it's a great idea.
"By and large, Management agrees that there is but one adequate solution to the problem ... a solution that can be applied only by Management itself."
