Security Architecture
Technical security controls, encryption ciphers, ephemeral in-memory packet arbitration, and compliance frameworks safeguarding enterprise voice infrastructure.
Ephemeral RAM Ingestion
Audio packets are held strictly in non-persistent, volatile RAM for real-time speech tokenization, with absolute memory zeroization upon call teardown.
End-to-End Encryption
Signaling channels run over TLS 1.3; media streams run encrypted via Secure Real-Time Transport Protocol (SRTP) using AES-256 ciphers.
Automated PII Redaction
Proprietary edge regex and acoustic silence detectors instantly scrub credit card numbers, SSNs, and health records from text transcripts.
VPC Peering & BYOC
Enterprise clusters can be pinned into dedicated customer VPCs (AWS, Google Cloud, Azure) with Bring Your Own Carrier (BYOC) SIP interconnects.
The PulseFlow Zero-Trust Voice Pipeline
An end-to-end audit of how an incoming telephone call is received, authenticated, processed through our speculative AI model, and purged without security leakage.
Edge POP Ingestion
Call arrives via BGP Anycast to nearest regional point of presence (Boston, Oregon, Frankfurt, Tokyo). TLS 1.3 handshake verifies carrier identity; SRTP session begins.
RAM-Only Speculative Loop
Acoustic frames stream directly into hardware accelerator RAM. Whisper STT + fine-tuned neural models evaluate caller intent with sub-40ms vector RAG lookup.
Zeroization & CRM Dispatch
Neural TTS outputs streaming 48kHz audio back to the caller. Upon call completion, volatile audio buffers are overwritten with cryptographic zeroes.
Cryptographic Specifications & Infrastructure Safeguards
• SIP Signaling: TLS 1.3 with ECDHE-RSA-AES256-GCM-SHA384.
• Media Plane: SRTP with AES_CM_256_HMAC_SHA1_80 cipher suites.
• Webhook Handoffs: HTTPS with HMAC-SHA256 request signature verification for all n8n and CRM endpoints.
• Master Keys: Rotated every 90 days via FIPS 140-2 Level 3 Hardware Security Modules (HSMs).
• Ephemeral Session Keys: Uniquely negotiated per SIP dialog via Diffie-Hellman ephemeral key exchanges.
• Database At-Rest Encryption: AES-256 with KMS envelope encryption.
