Trust Your AI Agent
Sierra is designed with the highest commitment to trust and reliability.
Security and compliance
We stay on top of the latest AI security best practices, models, and research so you don’t have to.
Secure integration
AI should be flexible, but not with your security standards. Your agent will always follow your policies and security procedures whenever it accesses systems of record.
Complete compliance
Sierra is committed to maintaining the highest compliance standards for our customers, covering SOC 2, HIPAA , GDPR, and CCPA.
Supervisor models
To mitigate risks inherent in the non-deterministic nature of LLMs, Sierra wraps LLMs in supervisory layers to reduce hallucinations, ensure security, and prevent abuse.
Data governance and privacy
We protect your company and customer’s data, always enforcing your policies and following industry best practices.
Data governance
Agent OS enforces strict data separation between customers, so your data is always stored in your own, private Sierra workspace.
Data privacy
Any personally identifiable information (PII) shared with your agent is automatically encrypted and masked.
Specialized model training
Sierra’s proprietary models are trained on aggregated, de-identified example conversations and will never make their way into foundation model training sets.
Constellation of models
Sierra is built on a constellation of LLMs—combining frontier, open source, and proprietary models—so your agent can execute seamlessly and reliably.
Superior performance
Different models excel at different tasks. Your AI agent uses frontier models and proprietary, specialist models for making decisions, understanding user messages, and generating responses.
Continued innovation
Sierra will power your AI agent with the best available LLMs in the industry, so you (and your customers) are always benefitting from the latest developments.
Consistent reliability
Sierra automatically switches between LLM providers to optimize your agent’s performance and maintain service continuity in case one provider experiences an outage.
