Sovereign AI Reference Architecture for
SITA MIOS 7.0 & POPIA Section 72
As the State Information Technology Agency (SITA) mandates MIOS 7.0 to enforce in-country data residency, data sovereignty, and interoperability without foreign vendor lock-in, integrating AI agents across public services introduces critical data leak vectors. Custos™ provides the deterministic, in-kernel enforcer designed specifically for sovereign government infrastructure.
1. Zero WAN Cloud Egress
Guarantees 0 bytes of citizen telemetry or model prompt data leave South African borders. 100% compliant with POPIA Section 72.
2. <16µs Citizen PII Masking
Wire-speed Luhn-validated SA ID redaction, social grant numbers, and medical schemes before payloads reach local models.
3. 126µs Hardware Socket Cut
Terminates TCP sockets via SO_LINGER(0) immediately if an agent attempts volumetric registry scraping or exfiltration.
4. Open Interoperability
Implemented at the Linux socket layer. Works transparently across SITA data centers, Gijima managed environments, and open-source models without foreign lock-in.
Departmental Deployment Profiles
Protects social grant beneficiary registries, banking details, and means-test records from unapproved LLM scraping or shadow AI queries.
Enforces strict air-gapping over the National Population Register, biometrics metadata, and immigration databases.
Redacts ICD-10 diagnostic codes, laboratory specimen IDs, and clinical notes, preventing Ampath/Lancet-style bulk record exfiltration.
