Financial API Threats We Stop

Proactive protection against the most common attacks targeting payment and banking APIs

Card Testing Attacks

Attackers test stolen credit cards via rapid-fire payment API requests. We detect and block card testing patterns in real-time.

Prevention: Rate limiting per card BIN, velocity checks, behavior analysis

Account Takeover

Credential stuffing and brute force attacks against banking logins. We block suspicious authentication patterns before damage occurs.

Prevention: Login rate limiting, IP reputation, device fingerprinting

Transaction Manipulation

Parameter tampering to modify amounts, recipients, or currency. We validate all financial API payloads against tampering.

Prevention: Schema validation, parameter pollution detection, HMAC verification

Frequently Asked Questions

Common questions about G8KEPR for financial services

Is G8KEPR PCI-DSS compliant?

Yes. G8KEPR is PCI-DSS Level 1 certified and designed to help you maintain compliance with requirements 6.5, 6.6, and 11.4. We provide automated compliance reporting and evidence collection for your QSA assessments.

Our infrastructure undergoes quarterly ASV scans and annual penetration testing. All cardholder data environments are isolated and encrypted with AES-256.

How does G8KEPR handle payment data?

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.

Can G8KEPR help with BSA/AML compliance?

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.

What latency does G8KEPR add to transactions?

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 with sub-5ms latency SLAs.

Do you support cryptocurrency exchanges?

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.

What is your uptime guarantee?

G8KEPR guarantees 99.99% uptime with financial penalties for SLA breaches. Our multi-region architecture with automatic failover ensures your payment APIs remain protected even during outages.

We publish real-time status at status.g8kepr.com and provide 15-minute incident response SLAs for critical issues affecting financial services customers.
