Next Generation Lan

Hello Networkers, We are looking for something to manage our LAN. This would include all the usual suspects. PSIRT or similar notifications on code, automation of networks, micro segmentation all in an overlay fabric, streaming telemetry. Of course Cisco has DNA Center which is not to impressive at this time. Maybe when it's more mature, we would also like to be vendor neutral if possible. Just wondering what other folks are doing to accommodate the next generation lan. EVPN, VXLAN? etc. We are running routed access as well. Thanks in advance, Greg
