The AI Security Layer for financial services: SHA-256 hash-chain audit for SOC 2 CC7.2 + PCI DSS Req 10.5, PII / PAN auto-redaction, adaptive Z-score circuit breaker, and pre-mapped requirements across 300+ PCI controls. All 4 platforms from $299/mo.
Proactive protection against the most common attacks targeting payment and banking APIs
Attackers test stolen credit cards via rapid-fire payment API requests. Sliding-window rate limit per BIN + adaptive Z-score breaker flag burst patterns before authorization is attempted.
Credential stuffing and brute force attacks against banking logins. Zero Trust risk scoring flags ≥5 failed attempts/hr (+30 points) and impossible travel (+50 points) — over 80 triggers step-up MFA.
Parameter tampering to modify amounts, recipients, or currency. Schema validation, parameter pollution detection, and HMAC signature verification block tampered payloads at the gateway.
API Security + MCP Security + AI Gateway + Verification Engine — unified under one correlation ID for financial workloads
Pre-mapped to PCI DSS v4.0 across 300+ requirements. Cross-framework sync means a SOC 2 control automatically contributes evidence toward PCI where they overlap.
Secure AI agents that analyze transactions for fraud. Every tools/call passes 7 sequential checks — permission, MFA, rate limit, rug-pull (SHA-256 drift), threat detect, forward, response scan — before touching customer data.
Route LLM calls for credit risk scoring, loan underwriting, and fraud analysis. Adaptive Z-score circuit breaker (statistical, not threshold) for failover; PII / PAN scrubbing before LLM processing.
Validate every AI-driven risk decision before it moves money or denies an applicant. Real-time enforcement with staged rollout; BLOCK-capable on selected critical paths.
Built for banking, payments, and crypto compliance. Every feature pre-mapped to financial regulatory standards.
Every API request appended to a SHA-256 hash chain with all-zeros genesis block. Three verification levels (full / single / last-N) prove logs haven't been modified — satisfies SAR reporting and PCI Req 10.5.
Detect suspicious transaction patterns: rapid transfers, unusual amounts, geographic anomalies. Block fraud before money moves with adaptive Z-score circuit breakers per endpoint.
Pre-built rules for banking, payments, and crypto. Customize for your specific risk tolerance and regulatory requirements.
Automated KYC/AML checks at the API layer. Integrate with your existing identity verification providers seamlessly.
Automated incident response for fraud events. Block suspicious accounts, freeze transactions, and alert your team in real-time with configurable playbooks.
Automated report generation for regulatory filings. SAR, CTR, and CMIR reports pre-populated with API transaction data and ready for submission.
Zero code changes to your payment APIs or AI fraud stack. Sub-5ms gateway proxy overhead on cached, single-region paths.
Not in Anthropic's MCP spec. Not in API gateways. Not in WAFs. Platform-level additions built for financial workloads.
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.
SHA-256 hash of every fraud-detection 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.
Statistical, not threshold-based. Z-score > 3.0 against per-hour time-of-day baselines (markets open vs overnight). 4 overlapping sliding windows (1m/5m/15m/1h). Progressive recovery (10→25→50→100%).
Every event linked across all four pillars via shared correlation ID. One query: "Show me everything that happened from this transaction — across MCP + API + Gateway + Verification." Architecturally impossible when layers are separate products.
SHA-256 genesis block, each entry signing the previous. Three verification levels (full / single / last-N). Tamper-evident evidence for SOC 2 CC7.2, PCI DSS Req 10.5, and SAR/CTR filing recordkeeping.
Cross-session attack detection: 6-dimension risk score (max 110) across tool sensitivity, data volume, burst, denials, prior detections, and tool diversity. Catches coordinated multi-account fraud and 24h slow-and-low patterns.
A suspicious transaction event traces forward to the AI fraud-model tool call it triggered, the payment API response, and the verification check that caught any drift.

Common questions about G8KEPR for financial services
G8KEPR implements security controls aligned with PCI-DSS requirements 6.5, 6.6, and 11.4. We provide automated compliance reporting and evidence collection to support your QSA assessments. Formal PCI-DSS certification requires a Qualified Security Assessor (QSA) assessment, which is the customer's responsibility.
Our infrastructure undergoes annual penetration testing. All cardholder data environments are isolated and encrypted with AES-256.
G8KEPR operates as a security proxy—we inspect API traffic for threats but don't store cardholder data (PANs, CVVs). Sensitive data is automatically detected and redacted from logs using our PCI-compliant tokenization.
For payment webhooks (Stripe, Adyen, etc.), we verify signatures and scan for replay attacks without accessing the underlying transaction data.
Yes. G8KEPR provides transaction monitoring rules specifically designed for Bank Secrecy Act compliance. We detect structuring patterns ($9,999 transactions), velocity anomalies, and suspicious activity that may require SAR filing.
Our audit logs are designed to meet FinCEN recordkeeping requirements with 7-year retention and tamper-evident hash chains.
G8KEPR adds less than 10ms of latency to API requests. Our edge network processes security rules at 200+ locations globally, ensuring minimal impact on transaction processing times.
For ultra-low-latency requirements (high-frequency trading, real-time payments), we offer dedicated infrastructure targeting sub-5ms routing overhead SLAs.
Yes. G8KEPR protects cryptocurrency exchanges, wallets, and DeFi platforms. We have specific security rules for wash trading detection, withdrawal velocity limits, and wallet draining prevention.
We integrate with Travel Rule compliance providers and support blockchain-specific threat intelligence feeds.
G8KEPR targets 99.9% uptime with our multi-region architecture and automatic failover to ensure your payment APIs remain protected even during outages. Enterprise plans include SLA terms — contact sales for details.
We publish real-time status at status.g8kepr.com and provide 15-minute incident response SLAs for critical issues affecting financial services customers.
Every transaction event appended to a hash-chain audit log. Cross-framework sync — a SOC 2 control contributes evidence toward PCI, GDPR, and ISO 27001 where they overlap.
"-Ready" / "aligned" reflect capability posture. PCI-DSS certification requires a Qualified Security Assessor (QSA) engagement on the customer's side; SOC 2 Type II observation in progress with external audit engagement H2 2026.
