large-scale use

Hi guys,

I manage a structure with about 5000 users on 3500 client workstations; web infrastructure is managed by squid and squidguard proxies in cluster HA and I would like to replace them with pi-hole, on clustered redundant hardware. I really like it, compared to what I was thinking, pfsense with pfblockerNG that would be your competitor.
Do any of you recommend it to me? have you tried it? tips?
thanks a lot, this is my first post …

Pi-hole is neither a proxy nor a firewall - it is a filtering DNS forwarder.

As such, Pi-hole is not a replacement option for squid or pfsense.
