I asked on the Alpha forums if Hackshield would in at release.
Got a response that it is easy to circumvent and a lot of people complaining about it.

There is a lot of rage on the forums about Hackshield. Just about anything on the computer can set it off. For me it was Webroot antivirus and the game would exit every 2 - 3 minutes. If I disable my AV it the game works fine.

There are still quite a few bugs but if they got rid of Hackshield things would be much better. At the moment they are using an older code of the game so it is very ping dependent, living in Australia I have a bad ping so can't spam DPS skills as fast as others with low pings. This is apparently fixed in the Russian version though.

I was pretty cranky by the time I finished fixing the crashes and got the game working last night but it all went away once I started playing. Can't put my finger on anything but the game just sucks you in. It is the little things like consumable drinks that are on barrels near NPCs, these give you a 30 second strength buff so you run much faster or fight much better. Little things that make the world feel really fleshed out. And I know I passed a lot of things that I want to go back and see what they do.
Then my character levelled to 5 and I could open up a new class, I was an archer and then picked witch...so a bow wielding witch. I like it. And the skills all kind of work off each other. I had two bow skills, one that snared and if I use the second ability the snare is increased. I picked up a witch ability that works off the increased snare and roots and dots the mob.

Being an old and jaded gamer I was surprised when I woke up early to play the game before work. And waking early for me is 5am as I leave at 6 for work!
