SECURITY AT A GLANCE

How does DigiPay.Guru secure digital payment infrastructure?

DigiPay.Guru applies layered security controls across applications, APIs, infrastructure, data, user access and software development processes. These controls are supported by security testing, auditability and applicable industry certifications.

Application Security

Authentication, authorization, secure configuration and application-level controls.

RISK LANDSCAPE

Payment infrastructure has more than one security risk

A payment platform has to protect more than an application login. Security must address the application, APIs, financial transactions, sensitive data, privileged access, infrastructure and software supply chain.

DigiPay.Guru Security Strategy

Defense-in-depth requires eliminating single points of failure across identity, code, communications, storage, and runtime operations.

Every layer enforces independent security controls to ensure total defense-in-depth across the platform lifecycle.

APPLICATION SECURITY

Application security controls

Authentication

Identity verification through authentication mechanisms, with multi-factor authentication applied where applicable.

Authorization

Authorization determines what an authenticated user is permitted to access or perform.

Role-Based Access Control

RBAC helps restrict functionality and resources according to assigned roles and permissions.

Password Hashing

Passwords are protected using hashing mechanisms rather than reversible encryption.

API SECURITY

Payment API security

APIs connect payment infrastructure with applications, partners and financial services, making API authentication, authorization, validation and monitoring important parts of the security architecture.

#API Security AreaPurpose
01AuthenticationVerify API consumers
02AuthorizationControl permitted actions
03Request ValidationReduce malformed or malicious requests

06MonitoringIdentify suspicious activity

08Webhook SecurityProtect event-driven integrations
09Rate limitingReduce API abuse
💡

DigiPay.Guru API Defense Principle

Financial APIs must never trust incoming parameters. Every request is verified, authorized, schema-validated, and logged before touching payment processing layers.

DATA PROTECTION

Protecting sensitive financial data

Financial platforms process sensitive customer and transaction information, so data protection requires controls across transmission, storage and cryptographic key management.

TLS Protocols

Encryption in Transit

Data moving between systems is protected using TLS. Currently supported versions are confirmed as part of a technical review.

AES-256 Storage

Encryption at Rest

Stored sensitive data protection mechanisms are confirmed as part of a security architecture review.

HSM Backed

Key Management

Key generation, secure storage, access and rotation practices — including HSM usage where applicable — are detailed during technical evaluation.

INFRASTRUCTURE

Infrastructure security

Covers the hosting environment, network security, encrypted communication, VPN access, infrastructure access controls, environment separation and monitoring.

SECURE DEVELOPMENT

Secure software development lifecycle (SDLC)

Security is integrated into the software development lifecycle

01

SAST

Finds security weaknesses in source code before release.

02

DAST

Tests running applications from an external perspective.

03

SCA

Identifies vulnerabilities in third-party and open-source dependencies.

04

Penetration Testing

Independent, controlled security testing of the platform.

💡 DigiPay.Guru Security Insight

OWASP is a reference framework used to guide application security practice — it is not a certification DigiPay.Guru holds or claims.

ACCESS & AUDITABILITY

Control who can access what — and maintain an audit trail

Role-Based Access

Users receive permissions based on their responsibilities.

Privileged Access

Access to sensitive functions and resources is restricted.

Audit Trails

Relevant user and administrator activity is tracked.

Operational Visibility

Logs and monitoring support investigation and accountability.

EXPERT PERSPECTIVE

DigiPay.Guru's approach to payment infrastructure security

"In payment infrastructure, security cannot be treated as a single application feature. The security model needs to consider the full transaction lifecycle — from authentication and API access through data protection, operational controls, monitoring and auditability."

— Engineering & Security Leadership, DigiPay.Guru
