How does HTML5 compare in vpn security compared to ipsec or SSL?

When used with certificates, L2TP/IPsec is as secure as IPsec and the SSL VPN depending on how they're each configured.  Pure IPsec and SSL VPN can have the strongest security.  The HTML5 method should be at least as good as L2TP/IPsec using certificates.

The problem with HTML5 is that it's very resource intensive.  If you want to have more than a single, simultaneous user, you will want to use more powerful hardware.

In general, I like the SSL VPN method best.

Ok thank you.. bummer HTML5 VPN is freakin' slick. Why do they have all these cool features and say "Oh but don't use it"... Ha..

I like to use the HTML5 VPN for outside consultants that manage a single resource and don't need general network access.  They don't have to install anything and they don't get a copy of any of the client's certs.

What I was thinking was giving 3 users remote desktop access when out of the office. I bet this wouldn't cause too much overhead.

That depends on the hardware that UTM runs on.  In this case, I would prefer SSL VPN remote access with two-factor authentication over HTML5.  Let us know what you wind up doing.
