Certified FedRAMP® High
I am excited to announce that Sierra, in partnership with Knox Systems, has been certified FedRAMP High — the standard for cloud companies working with U.S. federal agencies. We’re proud to have achieved this milestone just over two years since launch, less than the time many companies take to get certified.
Hundreds of millions of people rely on the U.S. federal government for services — from navigating Social Security, Medicare, and Veterans Affairs to filing their tax return or renewing their passport. These are critical, complicated interactions, and AI agents built on Sierra can help make them simpler and faster. The same technology that’s being used by 40% of the Fortune 50 to transform their customer experience is now available to these agencies.
- Build once, deploy everywhere: Create consistent experiences across voice, chat and email in 58 languages available 24/7/365 — with industry-leading safeguards and CSAT.
- Simple to use, deeply capable: Empower teams to build and optimize agents. Proven at scale in complex cases across financial services, telecom, tech, healthcare, travel, and retail.
- Clear visibility, complete control: Understand and improve agent behavior with built-in testing, automated monitoring, maintain auditability, policy controls, and configurable guardrails.
- Long-term partnership, priced by outcomes: Work with an expert agent development team that’s done hundreds of deployments — and will keep you ahead as AI evolves. Only pay for the value delivered.
- Fast to launch, built to evolve: Deploy in weeks with agents that grow in sophistication as your ambitions grow.
Some of the largest and most regulated companies in the world — from Vanguard and Rocket Mortgage to Sutter Health — have chosen Sierra because we deliver measurable results, quickly. Cigna, a Fortune 20 healthcare company, got their agent into production in just eight weeks and reduced patient authentication time by 80%.
We've already begun working with government agencies, and we're excited to support more of them. Whether it’s helping someone understand their benefits, navigate their tax return, get answers more easily, or cutting rote, repetitive work so government employees can focus on the moments their expertise matters most.
