Insurance API Threats We Prevent

Proactive protection against threats targeting policyholder data and claims systems

Claims Fraud

Attackers submit fraudulent claims through APIs. Behavioral baselines + adaptive Z-score circuit breaker catch velocity anomalies and slow-and-low patterns over 24h sliding windows.

Prevention: Pattern analysis, velocity limiting, cross-claim correlation

Policy Data Exfiltration

Bulk scraping of policyholder PII, SSNs, and financial data via quote or lookup APIs. Sliding-window rate limits and response-size caps block enumeration attacks at the gateway.

Prevention: Rate limiting, anomaly detection, response filtering

Quote Manipulation

Attackers manipulate underwriting APIs to get fraudulent quotes. Schema validation, parameter pollution detection, and HMAC signature verification block tampered payloads before they reach the underwriting model.

Prevention: Schema validation, integrity checks, audit trails

Four Platforms for Insurance

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

API Security

Claims Protection

Secure claims, policy, and quoting APIs. Pre-mapped to PCI DSS v4.0 requirements, with a control crosswalk to overlapping SOC 2 controls.

  • Claims API fraud detection
  • Policy lookup rate limiting
  • PII/SSN data masking

MCP Security

AI Underwriting

Secure AI agents that assist with underwriting decisions. Every tools/call passes 7 sequential checks — permission, MFA, rate limit, rug-pull (SHA-256), threat detect, forwarding, response scan — before touching risk databases.

  • AI underwriting audit trails
  • Risk model access control
  • Decision explanation logging

AI Gateway

Risk Assessment

Route LLM calls for risk assessment and claims processing. PII / SSN scrubbing before LLM processing; adaptive Z-score circuit breaker for failover.

  • Multi-LLM routing with failover
  • PII scrubbing before LLM calls
  • Claims summarization security

Verification Engine

4 Validation Layers

Validate every AI-driven underwriting or claims decision before it approves a policy or denies a claim. Real-time enforcement with staged rollout; BLOCK-capable on selected critical paths.

  • PII / SSN masking + forbidden-phrase constraints
  • Source grounding (hallucination detection on AI rationales)
  • Structural validation (ACORD, JSON schema, regex)

Every Tool Call Passes 7 Sequential Checks

Zero code changes to your claims systems or AI underwriting stack. Target: Sub-5ms gateway proxy overhead on cached, single-region paths.

1
Permission check
RBAC: does this adjuster have access to this claim or policy?
2
MFA verification
TOTP required for high-value claims, underwriting overrides, and SIU operations
3
Rate limiting
Sliding-window check, Redis-backed with in-memory fallback
4
Rug-pull verification
SHA-256 of tool definition vs. registered hash — block on drift
5
Threat detection
Scan tool arguments for injection patterns + PII / SSN markers
6
Server forwarding
Execute via stdio subprocess, HTTP, or WebSocket transport
7
Response scanning

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 insurance 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 underwriting 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 (catastrophe surge vs steady-state). 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.

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 SOC 2 CC7.2, NAIC Model #668 audit, and SIU fraud 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 organized claim-fraud rings 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.
