Security Built Into Every Layer, From Browser to Carrier.
From WebRTC SRTP media encryption to field-level CRM permissions and cryptographic HMAC webhooks, Callflow safeguards your enterprise customer conversations.
Layered Zero-Trust Architecture
Every request, audio packet, and database query traverses isolated, verified security boundaries.
1. Edge & Identity
Cloudflare DDoS mitigation, TLS 1.3 termination, SAML 2.0 SSO, MFA enforcement & IP filters.
2. Media Engine
SRTP encrypted voice packets, Opus 48kHz codec, private WebRTC gateways & isolated SIP relays.
3. Data & Storage
AES-256 encrypted database volumes, isolated tenant schemas, and immutable write-ahead audit logs.
4. Compliance Vault
PCI-DSS automatic DTMF muting, role-gated recording playback, and automated retention lifecycle policies.
Enterprise Governance & Data Protection
Built to satisfy stringent InfoSec and banking audits across North America, Europe, and India.
Authentication & Identity
Enforce multi-factor authentication (MFA/TOTP), SAML 2.0 Single Sign-On (Okta, Azure AD, Google Workspace), and automated session timeouts.
Granular Authorization & RBAC
Strict separation of duties between Administrator, Sales Manager, Agent, Support, and Executive Viewer roles with field-level visibility gates.
Agent Access Control (ACL)
Prevent unauthorized phone access by locking outbound calling permissions, phone number masking, and campaign queue visibility to assigned agents only.
Encryption in Transit & at Rest
All web traffic and WebRTC media streams are protected with TLS 1.3 / SRTP. Customer databases and call audio files are encrypted at rest with AES-256 GCM.
API Gateway & Webhook Security
Cryptographic HMAC-SHA256 request signatures, scoped Bearer token credentials, automated IP whitelisting, and strict per-tenant rate limiters.
Immutable Security Audit Logs
Every record export, permission change, audio playback, and user login is permanently recorded with user ID, IP address, and timestamp.
Call Recording Security & PCI Redaction
Audio recordings are stored in private isolated buckets. Automated AI speech filters mute and redact sensitive payment card details.
Automated Backups & Disaster Recovery
Point-in-time database recovery (PITR) with continuous cross-region replication across Tier-1 cloud zones, tested quarterly for failover.
Hardened Cloud Infrastructure
Hosted in SOC 2 Type II compliant AWS/GCP data centers with automated network firewalls, DDoS mitigation, and container isolation.
Common InfoSec & Compliance Questions
Detailed technical answers to common questions about data residency, carrier access, and penetration testing.
Callflow operates regional data clusters in AWS/GCP Tier-1 facilities across India (Mumbai), Europe (Frankfurt), and the United States (Virginia). Customers can choose their primary data residency zone during workspace onboarding to satisfy regional data sovereignty requirements.
