Penetration testing
for Fintech
Fintech Penetration Testing by Researchers With 150+ Published CVEs and 10 Years of Experience Testing Financial Technology Platforms
Fintech Penetration Testing That Reduces Risk
Why most fintech penetration testing fails to reduce risk:
Development teams get reports they can't act on
Security leaders spend weeks arguing about priorities
Boards receive technical documents without business context
We show you what breaks, how it breaks, and what customer data is exposed
Why Fintech Companies Choose AFINE for Penetration Testing
We've spent 10 years testing payment processors and digital finance platforms in production, and found hundreds of critical vulnerabilities. You get researchers who know what breaks in modern fintech infrastructure, and reports that show exactly how we exploited your environment. Each finding includes working proof-of-concept and business impact.
Our Services
What We Cover in Fintech Penetration Testing
Digital Payment Platforms
We reverse engineer payment applications to understand actual behavior versus documentation. Test transaction processing, payment tokenization, and API security. Verify PCI DSS compliance and PSD2 Strong Customer Authentication. Analyze concurrent transaction handling for race conditions and business logic flaws.
Mobile Fintech Apps
We reverse engineer applications to understand actual behavior versus documentation. Test data storage, crypto implementation, and traffic interception. Verify security on jailbroken/rooted devices. Authentication and authorization across different device states.
Payment and Open Banking APIs
We enumerate endpoints and test authorization boundaries between users and transactions. Analyze API authentication, OAuth/OpenID flows, and rate limiting. Check business logic flaws specific to payment processing. Test PSD2 compliance and third-party integration points.
Cloud Infrastructure and Microservices
We simulate breach scenarios from internet-facing APIs to cloud infrastructure. Test Kubernetes configurations, container escape paths, and privilege escalation. Review IAM policies across AWS/Azure/GCP. Analyze microservices authentication, inter-service authorization, and secrets management. Test CI/CD pipeline security.
Third-Party Integrations and API Ecosystems
We assess security at integration points and trust boundaries. Test authorization across partner connections including Plaid, Stripe, and KYC providers. Evaluate API key management, webhook security, and callback validation. Analyze supply chain risks from npm packages and dependencies.
Blockchain and Cryptocurrency Systems
We test blockchain nodes, cryptocurrency wallets, and smart contracts. Analyze wallet key management and transaction signing. Review smart contract code for reentrancy, integer overflow, and access control issues. Test exchange hot/cold wallet separation and withdrawal authorization.
Social Engineering Testing for Fintech
We run spear phishing against privileged users, phone-based social engineering targeting customer support, and attempts to manipulate KYC processes. Test employee awareness with realistic scenarios specific to fintech operations and customer account access.
The Enterprise Security Software We Hacked
Our Fintech penetration testing discovers vulnerabilities in the platforms that major financial institutions depend on. We exploit both known CVEs and the vulnerabilities nobody's documented yet.

Dual-Track Reporting
Security engineers get exploitation details and attack paths. Leadership gets business impact covering compliance, customer data, and operational continuity.
Immediate Risk Intelligence
Critical discoveries during fintech security testing reach you within 48 hours. You understand risk exposure as testing progresses, not weeks after engagement ends.
Fix-It Roadmap
Remediation prioritized by exploitability in your environment. You get CVSS scores and attack chain documentation showing what adversaries would target first in your payment infrastructure.
Tailored Red Team Engagement
Red team security testing methodology tailored to your cloud-native architecture, API landscape, and regulatory requirements.
Dual-Track Reporting
Security engineers receive exploitation details and proof-of-concept code. Leadership receives business impact analysis covering operational risk, safety exposure, and regulatory compliance.
Immediate Risk Intelligence
Authorized stakeholders receive confidential briefings on critical findings during red team security testing. You see what we've compromised and potential business impact as testing progresses.
Fix-It Roadmap
