Hi Nator
Yes Trend Micro is supported, you can use it with the Host Checker in order to give access or remidiate a user. Regarding the enforcer, if you want to do Layer 3 enforcement ( With TCP/IP access list ) you have to get a Juniper Firewall device. If your need is only Layer 2 enforcement ( VLAN Remediation and 802.1X ) , you can use every manufacturer that support it. From my side , i did test with Nortel , Cisco , Dell , Linksys and D-Link and it worked perfectly :-)
Thank you very much Sylvain for ur help
