Trust & security

Security

Open source: data handling per configured LLM providers. LangSmith deployment: review LangChain data handling policy.

SOC 2 Type II. ISO 27001. GDPR compliant. Financial services security standards. Enterprise data handling agreements.

Privacy notes

Data handling entirely through configured AI provider APIs. LangGraph itself does not transmit data. LangSmith deployment subject to LangChain's privacy policy.

FactSet processes financial research data and queries under enterprise data handling agreements. Customer data not used for model training per FactSet's enterprise terms.

Verdict

Pros

Graph-based control flow enables iterative agent behaviour unavailable in simple chains
Persistent state enables truly stateful multi-session agents
Human-in-the-loop checkpoints essential for production agent safety
Deep LangChain ecosystem integration for developers already on that stack

AI features grounded in FactSet's curated financial data produces more reliable results than general-purpose AI for financial queries
Mercury natural language access reduces time to find specific financial metrics and estimates
Document search semantic capability is well-calibrated for financial terminology
Integrated into existing FactSet workflows for professionals already on the platform

Cons

Steeper learning curve than CrewAI for developers new to graph-based thinking
Complexity overkill for simple single-turn AI tasks
LangChain dependency may be limiting for teams using other frameworks

Enterprise-only through existing FactSet subscriptions which carry significant subscription costs
AI features are value-adds within the broader FactSet subscription rather than standalone AI differentiation
Less AI-focused than dedicated financial AI platforms like AlphaSense for document research
