Streaming anomaly detection and incident investigation for federal zero trust architectures.
Three-model ensemble scoring, transparent per-model contributions, investigation-first analyst workflow, and OSCAL 1.1.3 continuous monitoring evidence emitted on demand. Built for FedRAMP Moderate and CMMC Level 2.
Six-tier architecture, end-to-end
Vector edge collectors normalize syslog, OTLP, and HEC payloads into ECS, route through Kafka, and land in a Postgres feature store with TimescaleDB hypertables. A three-model ONNX ensemble scores every event on the hot path. Analysts open every anomaly directly into an investigation panel with pgvectorscale similarity over 100M+ rows and a hash-chained audit log on every action. The reference deployment runs in AWS GovCloud or Azure Government; every tier scales to the platform’s 50,000 events-per-second target.

Read the deeper architecture
FedRAMP Moderate baseline, CMMC Level 2 aligned
The platform produces an OSCAL 1.1.3 SSP, component definition, and POA&M that validate against the NIST schema. 61 FedRAMP Moderate Key Security Indicators emit continuously and are Cosign-signed with 10-year retention. Audit logs are hash-chained, AU-9 generated occurred-at-canonical, and shipped to S3 with Object Lock in COMPLIANCE mode for production deployments.
| Control family | Controls | How SentryGrid implements it |
|---|---|---|
| Audit and accountability | AU-2AU-3AU-6AU-9AU-12 | Forward-only hash-chained audit log; AU-9 row recompute on verifyChain; S3 Object Lock in COMPLIANCE mode for 10-year retention. |
| Continuous monitoring | CA-7SI-4SI-4(2)SI-4(11)SI-4(13)SI-4(24) | OSCAL 1.1.3 evidence emitted continuously; 61 FedRAMP Moderate KSIs Cosign-signed; ensemble traffic-anomaly analysis on the hot path. |
| Identification and authentication | IA-2AC-2AC-3AC-6 | Keycloak OIDC against the agency IdP; Casbin RBAC + ABAC at the API gateway; default-deny on every resource type. |
| System and communications protection | SC-7SC-8SC-13 | mTLS between services; default-deny egress; FIPS 140-3 validated cryptographic modules in the production overlay. |
| Configuration management | CM-3 | Two-party approval queue on rule promotion, model promotion, and retention changes. Enforced at the API layer, not the UI. |
| Incident response | IR-4IR-5 | Investigation-first workflow with annotation, escalation chains, and runbook attachment. Every state transition lands in the audit chain. |
Built for the FY26 cybersecurity priorities
Aligned to OMB / ONCD FY2026 cybersecurity investment priorities and CISA’s Continuous Diagnostics and Mitigation program data quality plan. Independently developed under FedRAMP Moderate baseline controls; FY26 readiness lives in the trust center.
