CoCounsel (Thomson Reuters)
Data storage 0/3
What the vendor states (our summary):
US standard; region-based hosting in UK, Australia, Canada; no EU region stated
What this means: US/Canada only, no EU/CH option. Where data rests decides which law and which authorities can reach it. Swiss firms often require Swiss residency for client matters.
Where the AI runs / sub-processors 0/3
What the vendor states (our summary):
OpenAI GPT and Google Gemini interactions processed in the U.S.
What this means: Processed in the US. Storage and AI processing are often in different places. A tool can store data in Zurich and still send prompts to models in another country.
US Cloud Act exposure 0/3 ⚖︎
What the vendor states (our summary):
US processing by US providers
⚖︎ Judgment call: Prompts processed in the US by US providers per vendor.
What this means: US-domiciled vendor or US-only processing. The US CLOUD Act lets US authorities require US providers to disclose data in their possession, custody or control, wherever it is stored. This score is always an editorial judgment call.
Art. 321 SCC auxiliary terms 2/3
What the vendor states (our summary):
General confidentiality: Data Security Addendum commits to protect confidentiality of customer data; DPA binds staff to confidentiality; no auxiliary-person term
What this means: General confidentiality claim, no auxiliary-person term. Under Art. 321 SCC, auxiliaries of a lawyer are bound by professional secrecy, and Art. 13 para. 2 BGFA/LLCA makes the lawyer responsible for ensuring they respect it. Written auxiliary terms help document that.
revFADP / GDPR processing agreement 2/3
What the vendor states (our summary):
Public Thomson Reuters DPA v3 (effective 1 Feb 2025; GDPR/CCPA) with Swiss-U.S. DPF; FADP not named
What this means: GDPR DPA or US framework certification only. Art. 9 revFADP and Art. 28 GDPR require a contract (or legal basis) when a processor handles personal data on your behalf.
No training on customer data 3/3
What the vendor states (our summary):
Not used to train CoCounsel or LLMs, not stored by OpenAI/Google
What this means: Contractual no-training, including model providers. If customer data trains a model, confidential content could surface elsewhere. Look for a contractual ban that also binds model providers.
ISO 27001 / SOC 2 3/3
What the vendor states (our summary):
Thomson Reuters ISO/IEC 27001:2022 certificate (CERT-002113, valid to 2028-10-05) lists CoCounsel Essentials (Core, Drafting, Knowledge Search) in scope; CoCounsel Legal not named in scope
What this means: Own ISO 27001 or SOC 2 Type II. Independent audits (ISO 27001, SOC 2 Type II) give evidence that security controls exist and are tested.
