SECURITY
Business communication deserves strong protection.
Callsy is designed around tenant isolation, encrypted secrets, signed webhooks, access controls and audit logging.
Encrypted secrets
Keys and card tokens are stored encrypted.
Signed webhooks
Every phone and website request is signature-checked.
Card safety
Card numbers are entered in Helcim's secure form and never touch our servers.
Access controls
Staff sign-in with lockouts and re-checks for sensitive changes.
