Free 15-min Security Review
Let our engineers review your stack and identify your top 3 risks — no commitment required.
We give fintech and SaaS teams in India clear visibility into exploitable vulnerabilities and compliance gaps — before attackers find them.
TRUSTED BY SECURITY-CONSCIOUS TEAMS
THE CHALLENGE
Every new API, every deployment, every configuration change is a potential entry point. Most teams only find out after a breach.
Most vulnerabilities sit undetected for months. Without continuous testing, your attack surface grows with every deployment your team ships.
RBI, ISO 27001, PCI DSS, SOC 2 — knowing which framework applies and where you're failing is impossible without a structured audit.
Every sprint ships new risk. Without security in your pipeline, you accumulate technical debt that attackers will eventually collect on.
THE SOLUTION
From initial assessment to remediation verification, we handle every step of your security posture improvement.
We manually verify every finding. No false positives, no padded reports.
Deep expertise in payment infrastructure, UPI security, and RBI framework requirements.
Every finding explained in business impact, not technical jargon your board cannot act on.
We re-test after your team fixes each vulnerability at no additional cost.

WHAT WE DO
From your web app to your cloud infrastructure, we test everything attackers target first.
Manual and automated testing of your web applications to uncover injection flaws, authentication bypasses, and business logic vulnerabilities.
Deep assessment of your REST and GraphQL APIs for broken object-level authorization, mass assignment, and injection vulnerabilities.
Comprehensive review of your AWS and Azure environments for misconfigurations, exposed storage, and IAM policy weaknesses.
Structured gap assessments and audit readiness programs for SOC 2, ISO 27001, PCI DSS, and RBI cybersecurity framework requirements.
Realistic adversary simulations that test your people, process, and technology against multi-vector attack scenarios.
Security embedded into your CI/CD pipeline so every deployment is scanned before it reaches production.

Certified engineers. Manual verification. Business-focused reporting. Every engagement.
A comprehensive vulnerability assessment and penetration test of your web application, combining automated scanning with manual exploitation to find what scanners miss.
We focus on business logic flaws, authentication weaknesses, and injection vulnerabilities that represent real financial and reputational risk to your organization.
APIs are the primary attack surface in modern fintech applications. We test every endpoint — REST, GraphQL, and webhooks — against the OWASP API Security Top 10 and beyond.
Particular focus on broken object-level authorization, mass assignment, and authentication bypass vulnerabilities that automated tools routinely miss.
Cloud misconfigurations are the leading cause of data breaches. We audit your AWS and Azure environments against CIS benchmarks to identify exposed storage, overly permissive IAM policies, and insecure network configurations.
Every finding is mapped to your compliance requirements, so fixing security gaps simultaneously improves your audit readiness.
HOW WE WORK
Map attack surface, enumerate assets, identify entry points
Systematic vulnerability identification using OWASP, PTES, NIST
Manual verification of each finding — no unconfirmed scanner noise
Plain-English executive and technical reports delivered in 48 hours
Engineer support through your fix cycle + free re-test to close the loop
Home / Fintech Security
Payment infrastructure, UPI flows, KYC pipelines — we test what actually matters for Indian fintech companies operating under RBI oversight.
THE FINTECH RISK LANDSCAPE
UPI flows, payment gateway integrations, and wallet APIs carry the highest business risk. A single logic flaw can enable unauthorized fund transfers or double-spend attacks.
RBI's cybersecurity framework requires specific controls around incident reporting, patch management, and third-party risk. Most fintechs have significant gaps they are unaware of until an inspection.
Aadhaar data, PAN details, and financial history require specific technical and procedural controls. Exposure of this data carries regulatory penalties and customer trust damage that is difficult to recover from.
WHAT WE TEST IN FINTECH ENVIRONMENTS
REGULATORY COMPLIANCE
Schedule a free 30-minute scoping call. We'll identify your top RBI framework gaps in the first session.
We cover the RBI Master Direction on Information Technology Framework (2023), the Cybersecurity Framework for banks, and applicable sections of the NBFC guidelines. Our assessment maps findings directly to RBI control requirements.
Yes. We have tested payment systems integrated with UPI, IMPS, NACH, and NEFT infrastructure. Our team understands the specific security requirements for TPAP and payment aggregator environments under NPCI guidelines.
We use synthetic test data for all Aadhaar-related testing flows. Where access to masked Aadhaar numbers is necessary to test the integration, we work under strict NDA with documented data handling procedures that comply with UIDAI regulations.
Yes. We conduct PCI DSS gap assessments, help you scope your cardholder data environment, and provide the technical remediation support needed to pass a QSA audit. We have helped three Indian payment companies achieve PCI DSS Level 1 compliance in the past 18 months.
Home / Compliance
We translate complex compliance frameworks into actionable remediation plans your engineering team can actually execute.
FRAMEWORKS WE COVER
The de facto standard for B2B SaaS companies. SOC 2 Type II demonstrates to enterprise customers that your security controls operate effectively over time — not just at audit time.
We conduct a readiness assessment, identify gaps in your Trust Services Criteria coverage, and build the evidence collection and policy documentation needed to pass your Type II audit.
ISO 27001 is the international standard for information security management. Certification demonstrates a systematic approach to managing sensitive information — valued by enterprise customers and required by many procurement processes.
We guide you through the full ISMS implementation lifecycle, from risk assessment and Statement of Applicability to internal audit and certification audit support.
Required for any company that processes, stores, or transmits cardholder data. PCI DSS v4.0 introduces new requirements around authentication, targeted risk analysis, and automated log review that many Indian payment companies are not yet prepared for.
We scope your CDE, assess against all 12 requirements, and provide the technical remediation path to pass your QSA assessment — whether Level 1, 2, 3, or 4.
COMPLIANCE CHECKER

Results are indicative. Regulatory requirements vary by transaction volume and specific services offered.
Home / About
Defensify was founded on one conviction: Indian fintech companies deserve enterprise-grade security, delivered honestly.
"Most security companies sell reports. We sell outcomes. The difference is that we care whether your vulnerabilities actually get fixed."
— Founder, Defensify
Defensify was built by security engineers who grew frustrated watching companies fail audits they could have passed, or worse — getting breached through vulnerabilities a real test would have caught.
We focus exclusively on fintech and SaaS companies because we believe specialization matters in security. Generic security companies treat your payment infrastructure like any other web app. We don't.
To make enterprise-grade security accessible to every Indian fintech company — not just the ones that can afford a Big Four consulting retainer.
An India where no fintech company loses customer trust or regulatory standing because of a security gap that could have been identified and fixed.
Honesty about what we find. Clarity in how we report it. Commitment to seeing it fixed. We don't inflate findings or exaggerate risk.
