What the vendor documents
Recorded from the vendor's own trust, privacy and terms pages. "Not disclosed" means we found no public statement, not that the control is absent.
What the public documentation states
LexisNexis describes Lex Machina as litigation analytics for legal professionals using past behavior of attorneys, firms, parties, experts, courts and judges. The product page states that proprietary technology and AI-assisted attorney review convert raw legal documents into data sets; it does not name LLM providers for Lex Machina. LexisNexis' public sub-processor hub exists, but the audit did not find a tool-specific model-provider list or hosting region. The trust center states data is encrypted in transit and at rest and lists SOC 2 Type 2, ISO/IEC 27001 and HIPAA. The product page states customer data is not used to train AI models. Public pages checked did not publish a DPA, terms date, price, trial, seat minimum, private deployment, SSO or zero-retention term. For accuracy, the vendor describes the data-building method at a high level; no benchmark figures were found.
In the vendor's words
“proprietary technology and AI-assisted attorney review”
“We do not train or fine-tune our AI models using Customer Data.”
“Data is encrypted both in transit and at rest.”
“SOC 2 Type 2”
Not disclosed on public pages
"Not disclosed" records that no public statement was found where we looked, on the date shown. It does not assert that the control, term or figure is absent.
Not published on the pages we read on 2026-09-06: a DPA, model-provider names, hosting region, terms date, public pricing, seat minimum, minimum term, ISO 42001 statement, private deployment option, SSO detail, zero-retention term and accuracy benchmark figures. A law-firm procurement or DPIA file normally uses those facts to test confidentiality controls, GDPR Art. 28 processor coverage, residency obligations and lawyer supervision of analytics output.
Questions to put to the vendor
- Which sub-processors in the LexisNexis hub support Lex Machina, and where do they process customer data?
- Does the available DPA cover Lex Machina analytics data, AI-assisted attorney review and Protégé queries?
- What retention period applies to uploaded matter materials and generated analytics queries?
- Are SOC 2 Type 2 and ISO/IEC 27001 reports available for the Lex Machina service scope?
- What review protocol and error measurement support the AI-assisted attorney review workflow?
