Not sure about the "9", but Zscaler is a legit product/platform, I think one local IT consultancy sells it and another white-labels it and sells it that way.
I don't know much about how it works, though, can't help there.

Subject: [RndTbl] is zscaler9 a thing here?
Does anyone know of zscaler9 and its products? We are getting a large
number of DNS lookup hits on our DNS server from zscaler9 sattelites /
proxies. They appear to be a security provider who sits MITM to cleanse
traffic for corps?
Are there users of this product in MB, or Canada? Is this a big thing or
a little thing? Can anything justify large quantities of DNS queries from
them from all over the world? It looks like they intercept DNS and spoof
with their own stuff, but if their proxies are caching shouldn't they only
produce a sane/normal amount of hits?
