Cisco Umbrella
From Cisco's page here and here.
Cisco Umbrella has a Monthly DNS Query Average - more data. More info in product description
With regards to blocked security domains, please note that Cisco Umbrella blocks A, AAAA, ANY, CNAME, PTR, SRV, PRIVATE, SPF/DNS, NULL, SIG, and TXT records, so queries for other record types (MX, SOA, and NS) will be allowed, even though the category is blocked. However, requests for MX records of domains that have been categorized as “DNS Tunneling VPN” will be refused.
Cisco Umbrella won't block TXT records for “content filtering” but will for “threat filtering”. This makes sense as content filtering is for web page access which is A/AAAA/HTTPS records and not TXT.
