Payment Gateway Security Services

Securing Every Transaction. Protecting Every Customer.

As digital payments continue to surge, securing payment gateways is no longer optional—it's critical. Our Payment Gateway Security Services are tailored to safeguard financial transactions, ensure regulatory compliance, and defend against fraud, data breaches, and service disruptions.

We work closely with banks, fintech companies, payment aggregators, and e-commerce platforms to fortify the security posture of their payment infrastructure—across applications, APIs, middleware, and backend systems.


Our Methodology: Built for Speed, Designed for Trust

Our approach to Payment Gateway Security balances user experience, regulatory obligations, and real-world threat modelling. We follow a systematic, risk-based methodology tailored to meet the dynamic nature of payment ecosystems:

Threat Modelling & Asset Identification

Mapping data flows, critical components, and potential threats across the payment pipeline.

Compliance-Driven Risk Assessment

Evaluating systems against frameworks like PCI DSS, NPCI, and RBI guidelines.

Security Testing & Exploitation Simulation

Penetration testing across web, mobile, and APIs to expose vulnerabilities before attackers do.

Middleware & Infrastructure Hardening

Identifying and resolving weak points in the architecture, configurations, and service layers.

Continuous Monitoring Enablement

Providing guidance for logging, alerting, and fraud detection to secure transactions in real time.

Our methodology aligns with industry standards including PCI DSS v4.0, ISO 27001, OWASP, NIST SP 800-115, and NPCI security advisories.

Payment Gateway Security Program

Our Payment Gateway Security Program is a holistic offering designed to support secure digital transaction ecosystems. Key components include:

  • Compliance readiness assessments for NPCI, PCI DSS, and RBI mandates
  • Secure coding review of gateway applications and APIs
  • Penetration testing of payment flows and integrations
  • Middleware and load balancer security reviews
  • Cloud and on-prem infrastructure assessment
  • Third-party vendor and application risk assessments

Whether you are launching a new payment gateway or scaling existing operations, our program provides end-to-end visibility, control, and assurance.

Our Payment Gateway Security Services

NPCI Compliance

We help you meet National Payments Corporation of India (NPCI) guidelines, including specifications for UPI, RuPay, Bharat BillPay, and AePS platforms. Our services ensure that your architecture, encryption methods, logging controls, and system integration follow NPCI’s evolving compliance and security requirements—while minimizing operational overhead.

PCI DSS Compliance

Our PCI DSS readiness services guide you through the entire compliance journey—gap assessment, remediation support, vulnerability scans, penetration testing, and ROC preparation. Whether you're a Level 1 Merchant, Service Provider, or Payment Gateway, we simplify the process while ensuring full alignment with PCI DSS v4.0 standards, including encryption, tokenization, and secure authentication protocols.

Payment Gateway Penetration Testing

We simulate real-world attacks to uncover vulnerabilities in your payment flow, including card input forms, transaction APIs, OTP verification, and tokenization mechanisms. Our testing covers web apps, mobile apps, APIs, and backend integrations—with a focus on preventing data theft, fraud injection, session hijacking, and logic manipulation.

End-to-End Payment Gateway Architecture Review

We conduct a detailed review of your entire payment ecosystem—from customer touchpoints to processing layers, third-party integrations, fraud engines, and backend systems. This architectural assessment identifies design flaws, insecure data flows, and policy gaps, and provides actionable recommendations to fortify your security and uptime.

Payment Gateway Middleware Assessment

Your middleware is the engine that powers real-time processing. We analyse message queues, orchestration platforms, databases, and payment processors for misconfigurations, vulnerabilities, privilege escalation risks, and denial-of-service exposure. The assessment is protocol-aware (ISO 8583, REST, SOAP, etc.) and helps you close gaps in this critical layer.
