What is Sophos view on network access control?

I certainly wouldn't rely or use a UTM/XG for NAC. That's done at L2so you need to be looking at your switches and radius for 802.1x.

There was some interesting discussion ongoing in the EAP Sub forum.

Worth to read about NAC. 

Yeah, I was looking at that. It's interesting but I suspect there will be a few hurdles on the way and possibly a while before it's taken up. I understand the reasoning behind it as NAC can be a pain at times. It will be interesting to see how they deal with non managed clients and their interaction with switches etc

Thanks, I had seen that and it sounds good BUT it relies on devices having sophos endpoint client isntalled while a NAC solution protects agaisnt rogue devices too.

If anybody else finds this thread, there were a couple of interesting points mentioned in the comments. I think this one and the next 2 are to be highlighted: https://community.sophos.com/products/xg-firewall/sophos-xg-beta-programs/sfos-v17-5-early-access/f/sophos-xg-17-5-early-access/108538/sync-sec-important-announcement-on-synchronized-security-features-on-xg-v17-5-early-access/388405#388405 

I like the concept and it's another tool to use ie a NAC won't stop a virus spreading but this has the potential to. I do hope they adhere to standards to implement it and don't go of on a tangent like M$ does.

M$ in their infinite wisdom decided to create a non standard Wake on Lan proxy within their SCCM software. It allows clients with the SCCM client installed to share mac addresses so if a client goes to sleep, the mac address can switch to another client on that lan which then does the waking up.
Now that's fine, unless you've got a 802.1x network and it starts playing havoc with it when ports shut down due to seeing a new mac address. It's almost virus/worm like behavior and all because they decided to do their own thing like the did with their network load balancing etc.

So please Sophos.... don't do an M$ and create your own non standard protocol etc to achieve the end result.
