Security & Sovereign Infrastructure
Carrier-grade defenses, cryptographic isolation, zero-knowledge AI inferencing, and strictly localized Indian data residency engineered for banks, enterprises, and high-volume contact centers.
Dual-zone active-active nodes in Mumbai and Hyderabad with carrier cross-connects.
All SIP signaling and media packets encrypted end-to-end to prevent wiretapping.
Private VPC tenant isolation. Zero shared weights and zero public model leakage.
100% Indian Data Sovereignty & Physical Security
7Silicon Group guarantees that all voice payload data, call audio streams, SIP metadata, and customer transcripts remain strictly within the sovereign territory of the Republic of India.
- Primary telephony switches and media relays reside in Tier-3/Tier-4 MeitY-empaneled data centers in Mumbai (Maharashtra) and Hyderabad (Telangana).
- No customer audio packets or transcripts ever transit across international boundaries or cloud data centers outside India.
- Physical facilities feature biometric access controls, 24×7 armed perimeter security, redundant N+1 power generation, and dual-homed telecom fiber entry points.
Telephony Transport & Media Cryptography
Voice traffic is protected across every phase of traversal:
- SIP Signaling: Secured via Transport Layer Security (TLS 1.3 / TLS 1.2) with mutual certificate authentication (mTLS) between enterprise SBCs and our carrier core.
- Voice RTP Streams: Media is protected via Secure Real-time Transport Protocol (SRTP) utilizing AES-128-GCM cipher suites, preventing man-in-the-middle eavesdropping.
- Data at Rest: Call audio archives, CRM synchronizations, and database records are encrypted using AES-256 with enterprise Customer-Managed Encryption Keys (CMEK) option.
Sovereign AI Brain Isolation & Zero Training
For clients utilizing our Dedicated Sovereign VPC LLM or Persona Prompt Architecture:
- Each enterprise customer operates within a logically and cryptographically partitioned Virtual Private Cloud (VPC) with dedicated GPU vLLM instances.
- Customer speech-to-text transcripts, vector embeddings, and RAG document repositories are ephemeral or encrypted at rest in dedicated Postgres pgvector instances.
- No employee, contractor, or automated crawler can view raw conversational transcripts without authenticated customer authorization.
CERT-In Compliance & Incident Response SLA
In compliance with the Indian Computer Emergency Response Team (CERT-In) Cyber Security Directions under Section 70B of the Information Technology Act:
6-Hour Mandatory Notification: Any confirmed cybersecurity incident or unauthorized access attempt impacting customer systems is formally reported to CERT-In and affected enterprise clients within six (6) hours of discovery.
NTP Time Synchronization: All server logs and telephony switches are synchronized to the National Physical Laboratory (NPL) Indian Standard Time (IST) atomic clock servers.
Log Preservation: System, firewall, and access audit logs are archived securely within Indian borders for a mandatory period of 180 days.
