I need to compare/evaluate various DNS security products, meant to to prevent
users accessing malicious sites;  not sure if it'll help with spam (say user register
their emails in unsolicited sites & got spammed from hereon).

A few products below come to mind but I don't know how to go about
comparing/assessing:
Cisco Umbrella
Dyn
FoolDNS
Greenteam Internet
Infoblox
nexusguard
Quad9
OpenDNS (now under Cisco)
Cyren

Much appreciated some guidelines & inputs
