Enterprise-grade security, built in
Your customer conversations are sensitive. Opsei protects them with the controls large enterprises expect, so you can put AI on the front line with confidence.
Access & audit control
Role-based access, single sign-on (SSO), and per-user audit logs so you always know who saw and did what.
Encryption everywhere
TLS 1.3 encryption in transit and AES-256 encryption at rest for every conversation, record, and file.
SOC 2 Type II
SOC 2 Type II controls with independent annual audits covering security, availability, and confidentiality.
Data residency
Tenant-isolated data that is never used to train third-party models, with US-based data residency available on enterprise plans.
Works with the tools you already use
Opsei plugs into your stack two ways: Automated Workflows push new leads, customers, and tickets out to your other apps the moment they happen, and Live Answers let the AI look up real information from your systems mid-conversation.
Automated Workflows (outbound)
Fire secure webhooks on every new lead, customer, ticket, or ended conversation. Connect to your CRM, back office, or thousands of apps through Zapier, Make, and n8n. Every delivery is logged, retried, and testable.
Live Answers (inbound connectors)
Let the AI query your own HTTPS APIs while it is talking to a customer - order status, bookings, account details, a customer's plan - and reply with the live result on both chat and voice.
