We are pivoting out of a huge number of US services at my job. I think windows, Google, PaloAltoNetworks and Aws will be the last we leave, but infoblox is out next year (that's part of my job right now), and old Cisco hardware will stop being replaced by new Cisco hardware in 6 months.
Palo is starting to require telemetry that sends realtime data on rulebase and hitcount from every firewall to increase support effectiveness.
Are you replacing Cisco with Ericsson?
