Government API Threats We Stop

Proactive protection against nation-state actors and sophisticated cyber threats

Nation-State Attacks

Advanced Persistent Threats (APTs) targeting government APIs for espionage and data theft. Behavioral baselines + ML anomaly detection catch slow-and-low patterns over 24h sliding windows.

Prevention: ML-based anomaly detection, threat intelligence feeds, login risk scoring

Citizen Data Breaches

Unauthorized access to PII (SSNs, addresses, tax records) via government service APIs. Auto-redaction in audit logs; role-based access scoring per request.

Prevention: Access logging, PII detection, rate limiting, audit trails

Supply Chain Compromises

Third-party vendors with API access become attack vectors. SSRF guard on backend registration rejects RFC 1918 / 169.254 metadata addresses; per-key rate limits enforce granular control.

Prevention: API key restrictions, IP allowlisting, scope limiting

Four Platforms for Government

API Security + MCP Security + AI Gateway + Verification Engine — unified on one finding bus for federal workloads

API Security

NIST 800-53 Controls

Pre-mapped to NIST 800-53 Rev 5 and FedRAMP (84 controls, 3 baselines). A control crosswalk maps NIST 800-53 controls to their overlapping CMMC 2.0 and ISO 27001 controls.

  • AC-2: Account Management (API key lifecycle)
  • AU-2: Audit Events (comprehensive logging)
  • SI-4: Information System Monitoring

MCP Security

AI Agents

Secure AI agents for citizen services and case management. Every tools/call passes 7 sequential checks — permission, MFA, rate limit, rug-pull (SHA-256), threat detect, forwarding, response scan — before touching classified data.

  • Prompt injection detection for gov AI systems
  • Tool call monitoring for classified access
  • FISMA-compliant audit logs for AI

AI Gateway

Secure LLM Routing

Route LLM calls through government-authorized providers. PII / CUI scrubbing before LLM processing; adaptive Z-score circuit breaker for failover.

  • GovCloud-compatible LLM routing
  • PII/CUI scrubbing before LLM processing
  • US-only data residency enforcement

Verification Engine

4 Validation Layers

Validate every AI output before it touches a citizen record or case file. Real-time enforcement with staged rollout; BLOCK-capable on selected critical paths.

  • PII / CUI masking + forbidden-phrase constraints
  • Source grounding (hallucination detection on case rationales)
  • Structural validation (JSON schema, regex, expected structure)

Federal Compliance Features

Built for government security standards. Every feature pre-mapped to federal mandates for data protection, access control, and audit readiness.

FedRAMP Roadmap Deployment

Deploy on AWS GovCloud, Azure Government, or on-premise. Architecture designed for FedRAMP Moderate & High environments with documentation packages for your ATO process. FedRAMP authorization is on our roadmap.

  • FIPS 140-2 validated encryption
  • US-only data residency
  • Architecture supports air-gapped deployment
  • SSP & POA&M templates included

Append-Only Audit Logs

API requests are written to an append-only audit log. An HMAC-SHA256 hash chain with three verification levels (full / single / last-N) is implemented and tested but not yet recording in production. Mapped to AU-2, AU-3, AU-9, AU-12.

  • WORM Object Lock COMPLIANCE mode (when S3 is configured)
  • Three verification levels (chain verified daily since 2026-09-13)
  • 84-month audit retention by default
  • Exportable for OIG / IG investigations

Continuous Monitoring

FedRAMP ConMon readiness. Real-time security posture dashboards and automated dependency updates. Gitleaks secret scanning is a required check on every merge and Bandit runs on backend pull requests; CodeQL, Trivy, ZAP and Semgrep are configured but not running today.

  • Monthly POA&M reports
  • Incident response playbooks
  • SIEM export (CEF / STIX / JSON) and webhook forwarding
  • Real-time threat dashboards

Zero Trust Risk Scoring

Evidence toward Executive Order 14028 zero trust work: a 4-dimension composite risk score (device 25% / location 25% / behavior 30% / time 20%) computed and recorded on every login. Scores are logged for review and do not yet allow or deny requests.

  • Device, location, behavior and time factors per login
  • Impossible-travel detection
  • Elevated-risk logins logged for review

PII/CUI Data Classification

Automatically detect and classify sensitive data flowing through your APIs. Tag PII, CUI, and classified data with proper markings and enforce handling requirements.

  • SSN, DOB, address detection
  • CUI marking enforcement
  • Auto-redaction in logs
  • NARA retention compliance

Incident Response Automation

Automated incident detection, classification, and response workflows. Meet IR-4, IR-5, and IR-6 control requirements with playbooks designed for federal agencies.

  • Findings forwarded to your SIEM or a signed webhook
  • Automated containment actions
  • Evidence preservation chain
  • Post-incident analysis reports

Every Tool Call Passes 7 Sequential Checks

Zero code changes to your citizen-service APIs or AI agent stack. Target: Sub-5ms gateway proxy overhead on cached, single-region paths.

5 Capabilities You Won't Find Anywhere Else

Not in Anthropic's MCP spec. Not in API gateways. Not in WAFs. Platform-level additions built for federal workloads.

01

Hardened Local MCP Servers

MCP servers the proxy launches locally (stdio, off unless the operator sets MCP_STDIO_SERVERS_ENABLED) run in their own session (setsid), drop to nobody if started as root, and get no-new-privs, ambient capabilities cleared and RLIMIT_AS/FSIZE/NOFILE/NPROC ceilings. Remote (HTTP) servers are proxied and inspected, not sandboxed, and network egress is not filtered.

modules/mcp/interceptor_transport.py — _proxy_preexec
02

Tool Definition Hash Registry

SHA-256 hash of every tool definition pinned at tools/list. On every tools/call, the cached definition is re-hashed and compared. Drift raises MCPRugPullDetectedError, blocks execution, publishes a CRITICAL event.

modules/mcp/tool_registry.py • Redis-backed
03

Adaptive Z-Score Circuit Breaker

Statistical, not threshold-based. Z-score > 3.0 against per-hour time-of-day baselines. 4 overlapping sliding windows (1m/5m/15m/1h). Progressive recovery (10→25→50→100%).

gateway/ — 2,208 LOC combined
04

Cross-Pillar Correlation

Findings from all four pillars land on one threat-event bus. A compound correlator groups them in 5-minute windows by correlation ID and by organization + client IP, and raises one incident when they match a known multi-stage pattern: a prompt injection at the gateway plus an SSRF probe and a path traversal at the API from the same client become a single critical Lethal Trifecta finding.

modules/compound_correlator • findings.mcp_security.compound
05

Append-Only Audit Log

HMAC-SHA256 hash chain on authentication and domain events (since 2026-09-13), each entry signing the previous. Three verification levels (full / single / last-N). Control mapping (not an attestation) for AU-2/AU-3/AU-9/AU-12 control families and OIG investigations.

MCP Correlation Analyzer

Cross-session attack detection: 6-dimension risk score (max 110) across tool sensitivity, data volume, burst, denials, prior detections, and tool diversity. Catches coordinated APT activity and 24h slow-and-low patterns.

MCPCorrelationAnalyzer — alert at score > 50

One Finding Bus. All Four Pillars.

Every pillar publishes its findings to one threat event bus. The compound correlator joins findings on the same request by correlation ID, and separate requests from one client by organization + client IP.
