Data location
No data-location observation recorded yet.
The same question for every vendor: where SaaS vendors store EU data.
ClickHouse's subprocessor list names AWS, Microsoft and Google for hosting or infrastructure. Which SaaS vendors run on which cloud, and the sovereign offerings of each: sovereign clouds.

The count outside the EEA is arithmetic over the country column, not a judgement about lawfulness. A transfer outside the EEA can be perfectly lawful; whether this one is depends on your use, not on the vendor.
Every subprocessor in the registry, and which vendors name it: subprocessors.

Assurance
Does ClickHouse have a SOC 2 report?
ClickHouse says a SOC 2 Type 2 report is available on request. We read this on 2026-11-09.
- Available on request “COMPLIANCE SOC 2 Type 2”
Source: trust.clickhouse.com, 2026-11-09
Of the 114 vendors in this registry whose own pages mention SOC 2, 57 say the report is available on request, 1 links to the report itself, and 56 state it without saying how to get it. The type is the one the vendor names.
Is ClickHouse ISO 27001 certified?
ClickHouse states ISO/IEC 27001 certification, and says the certificate or audit report is available on request. We read this on 2026-11-09.
- Available on request “COMPLIANCE ISO/IEC 27001 COMPLIANCE”
Source: trust.clickhouse.com, 2026-11-09
On the same list ClickHouse also names ISO/IEC 27701. Each standard's page says how it relates to ISO/IEC 27001.
Of the 122 vendors in this registry whose own pages state ISO/IEC 27001, 16 link to the certificate, 43 say it is available on request, and 63 state it without saying how to get it. A certificate names the certification body, the scope and the expiry date: those are the three things to check.

Claimed means the vendor asserts the scheme on its own page and offers nothing further. Available on request means the report or certificate exists but sits behind a request, a login or an NDA. Neither is a certificate we have seen. That is a distinction an auditor makes, so we make it too.

What the authority publishes, not what the vendor claims. An entry covers the offering it names and nothing else: a FedRAMP authorisation for a government edition says nothing about the commercial service. No entry is not a finding about security - most vendors never apply - and an entry filed under a name not listed above would not have been found.
