Fintech penetration testing | Fintech pentest

Prices starting at $4,999.

Fintech penetration testing is a manual security assessment of financial applications, APIs, mobile apps, payment workflows, and cloud infrastructure. Researchers simulate attacks to identify exploitable weaknesses and provide practical remediation guidance.

Blaze's penetration testing services  assess the technical controls and business logic protecting accounts, transactions, and sensitive financial data.

We work with fintechs, challenger banks, and payment providers to assess risks that generic scans can overlook:

• Unauthorized access across customers, accounts, roles, and tenants
• Payment manipulation, transaction replay, and race conditions
• Authentication, session, and step-up MFA weaknesses
• Transaction approval and signing flaws
• Abuse of onboarding and KYC workflows
• Open banking API authorization and consent controls
• Cloud permissions, exposed services, and configuration weaknesses

Findings explain the attack prerequisites, affected security boundaries, and business impact so your team can prioritize fixes.

Explore our banking and fintech security assessments .

Assessments are tailored to your architecture, financial workflows, and agreed threat model. Scope can include:

• Web applications for banking, trading, payments, and digital wallets
• REST, GraphQL, SOAP, and gRPC APIs
• Open banking APIs and relevant FAPI security controls
• iOS and Android banking and payment apps
• AWS cloud environments and configuration
• External and internal networks
• Payment processing, transaction logic, and concurrency controls
• Agreed point-of-sale interfaces and supporting APIs

Authenticated and unauthenticated testing can cover customer, operator, administrator, and service-to-service access. Source-code-assisted testing can help investigate security-critical components where access is available.

Blaze is a CREST-accredited company. Our researchers hold certifications including OSCP, OSWE, OSCE, CRTO, and CREST CRT. Testing combines manual investigation with specialist tools, with findings validated before reporting.

Relevant findings may support PCI DSS, SOC 2, ISO 27001, SWIFT CSP, and DORA-related assurance activities where scope and requirements align.

We agree the required systems, testing depth, and reporting context during scoping. A standard fintech pentest is not a substitute for DORA threat-led penetration testing, and one report does not automatically satisfy every framework.

• Executive summary explaining key risks and business impact
• Technical report documenting scope, methodology, findings, and reproduction steps
• Severity ratings, remediation priorities, and practical correction guidance
• Relevant control mappings where agreed
• Assessment schedule and any retesting terms defined before work begins

Prices start at $4,999. Final pricing depends on scope, complexity, and testing depth.
