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, zero-trust validation

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 under one correlation ID for federal workloads

API Security

NIST 800-53 Controls

Pre-mapped to NIST 800-53 Rev 5 (1,000+ controls) and FedRAMP (84 controls, 3 baselines). Cross-framework sync contributes evidence toward FISMA, CMMC 2.0, and ISO 27001 where they overlap.

  • 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

Immutable Audit Logs

Every API request appended to a SHA-256 hash chain with all-zeros genesis block. Three verification levels (full / single / last-N). Satisfies AU-2, AU-3, AU-9, AU-12 control evidence.

  • WORM Object Lock COMPLIANCE mode (S3)
  • Three verification levels (full / single / last-N)
  • 84-month retention default (configurable)
  • Exportable for OIG / IG investigations

Continuous Monitoring

FedRAMP ConMon readiness. Real-time security posture dashboards, automated vulnerability scanning, and 67 CI workflows (CodeQL, Trivy, ZAP, Gitleaks, Semgrep) running every commit.

  • Monthly POA&M reports
  • Incident response playbooks
  • Automated SIEM integration
  • Real-time threat dashboards

Zero Trust Access Control

Implement Executive Order 14028 zero trust requirements. 4-dimension composite risk score (device 25% / location 25% / behavior 30% / time 20%) drives access decisions per request.

  • PIV/CAC smart card authentication
  • Device posture validation
  • Context-aware access decisions
  • Microsegmentation support

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.

  • US-CERT/CISA reporting integration
  • 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. Sub-5ms gateway proxy overhead on cached, single-region paths.

Permission check
RBAC: does this clearance level access this classified or restricted resource?
2

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

OS-Level MCP Sandbox

Subprocess MCP tools execute inside a hardened Linux sandbox. RLIMIT_CPU/AS/NOFILE/NPROC, setsid() process-group isolation, capability dropping, per-tool egress filtering, and shell binaries removed.

modules/mcp/sandbox/executor.py — 934 LOC
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

Every event linked across all four pillars via shared correlation ID. One query answers the IG's "what happened from this case?" Architecturally impossible when layers are separate products.

mcp_contexts • parent-child causal chain
05

Hash-Chain Audit System

SHA-256 genesis block, each entry signing the previous. Three verification levels (full / single / last-N). Tamper-evident evidence for AU-2/AU-3/AU-9/AU-12 control families and OIG investigations.

7 modules • 3,866 LOC combined
+

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 Correlation ID. All Four Pillars.

A citizen-service request traces forward to the AI tool call it triggered, the case-management API response, and the verification check that caught any drift.
