Hello, I have one, not nulled, but the full one. I also have the free one.
Asking for a nulled security plugin is like asking for a damaged car to travel 1000km : nonsense!!
You need a security plugin for what? Protecting you website? ok
So you'll install a nulled one that could literally contains a malware that the original one doesn't have? WTF
Email me on contact @ secupress.me (yep, i'm the creator of SecuPress, Julio Potier) and I'll give you a good coupon, but don"t ask to be hacked here -_-'
