Codesecure Solutions is a leading API security testing company based in Chennai, India, specializing in identifying and remediating vulnerabilities across REST, GraphQL, SOAP, and gRPC APIs. With modern applications relying heavily on APIs to power mobile apps, web platforms, and third-party integrations, a single insecure API endpoint can expose your entire organization to data breaches and unauthorized access.
Our dedicated API security audit team combines deep manual testing expertise with advanced automated tools to uncover hidden flaws in your API architecture. We test against the complete OWASP API Security Top 10 framework, covering broken object level authorization, authentication flaws, excessive data exposure, rate limiting gaps, and injection vulnerabilities. Whether you are building a fintech platform, healthcare application, or enterprise SaaS product, our API security testing services ensure your data exchange layers are fortified against real-world attack scenarios.
Our API security testing services in Chennai cover every aspect of API security, from authentication mechanisms to business logic flaws. We take a holistic approach to ensure your APIs are resilient against both automated attacks and sophisticated manual exploitation.
Our API security testing methodology is aligned with the OWASP API Security Top 10, ensuring comprehensive coverage of the most critical API vulnerabilities that organizations face today.
We test for BOLA vulnerabilities where attackers manipulate object IDs in API requests to access data belonging to other users. This is the most prevalent API vulnerability and can lead to massive data breaches if left undetected.
Our testers evaluate API authentication mechanisms for weaknesses in token generation, session management, password reset flows, and multi-factor authentication implementation that could allow attackers to impersonate legitimate users.
We analyze API responses for unnecessary data fields, sensitive information leakage, and improper filtering. APIs often return more data than needed, relying on the client to filter, which creates serious data exposure risks.
We assess whether APIs properly enforce rate limits, request size restrictions, and pagination controls. Without these safeguards, APIs become vulnerable to denial of service attacks, brute force attempts, and resource exhaustion.
Our team checks for missing security headers, overly permissive CORS policies, verbose error messages, unnecessary HTTP methods, default credentials, and TLS misconfigurations that weaken your API's security posture.
We test all API input points for SQL injection, NoSQL injection, command injection, LDAP injection, and server-side request forgery. Our manual testing goes beyond automated scanners to catch complex injection chains.
Organizations across Chennai and India trust Codesecure Solutions for their API security testing needs. Here is what makes our approach effective and reliable.
APIs are the connective tissue of modern digital businesses. Our API security testing experience spans multiple industries in Chennai and across India.
We follow a structured, repeatable methodology for API security testing that combines industry standards including the OWASP API Security Testing Guide, PTES, and our proprietary API-specific testing framework.
We begin by reviewing your API documentation (Swagger, OpenAPI, Postman collections), discovering undocumented endpoints, and mapping the complete API attack surface. This includes identifying all authentication mechanisms, data models, and inter-service communication patterns.
We thoroughly test OAuth 2.0 flows, JWT token handling, API key security, session management, and role-based access controls. This includes testing for privilege escalation, horizontal access control bypass, and token manipulation attacks.
Every API input parameter is tested for injection vulnerabilities including SQL injection, NoSQL injection, XML injection, and command injection. We also test request body manipulation, content type confusion, and mass assignment vulnerabilities.
We analyze API workflows for business logic flaws that automated scanners cannot detect. This includes race conditions, workflow bypass, price manipulation, and abuse of legitimate API functionality for unintended purposes.
APIs handle the most sensitive data in your organization. Regulatory frameworks increasingly mandate API security testing as part of compliance requirements. Our API security assessments help you meet these obligations effectively.
APIs are the primary vector through which sensitive data flows between systems. Whether you are processing payment card data, personal health information, or customer records, your APIs must be tested regularly to meet compliance requirements. At Codesecure, we align our API security testing with the specific controls required by each compliance framework.
For organizations pursuing PCI DSS compliance, our API testing covers Requirement 6 (secure development) and Requirement 11 (regular security testing). For HIPAA-covered entities, we test APIs that handle electronic protected health information for proper encryption, access controls, and audit logging. Our web application security testing complements API testing to provide complete coverage of your application layer.
Indian businesses face additional regulatory requirements. The RBI mandates API security testing for banks, NBFCs, and payment aggregators operating digital payment systems. The DPDP Act 2023 requires data fiduciaries to implement reasonable security safeguards for personal data processed through APIs. SEBI guidelines require stockbrokers and depository participants to conduct regular security testing of their trading APIs.
Our API security testing reports include compliance mapping sections that document how each finding relates to specific regulatory controls. This makes it easy for your compliance team to demonstrate due diligence during audits. Combined with our network security audit and cloud security assessment services, we provide a complete security testing program that satisfies even the most stringent regulatory requirements.
Common questions about our API security testing services in Chennai.
An API security testing service in India from Codesecure covers authentication and session handling, object level authorization across roles, input validation, rate limiting, and business logic abuse. We run authenticated tests against every documented endpoint, intercept traffic to catch shadow APIs, and validate that secrets and tokens are not leaking through response bodies. The deliverable is a developer ready report with curl proofs of concept for each finding.
Our test plan is mapped to every category of the OWASP API Top 10, starting with Broken Object Level Authorization and Broken Authentication, which cause most real breaches today. We also check Broken Object Property Level Authorization, Unrestricted Resource Consumption, Server Side Request Forgery, Security Misconfiguration, and Unsafe Consumption of APIs. Each finding cites the exact OWASP category so your developers can look up remediation guidance directly.
Yes, a REST API security audit starts with an OpenAPI or Postman collection review, followed by dynamic testing of every endpoint with multiple user roles. We confirm that object IDs cannot be manipulated across tenants, tokens expire correctly, error messages do not leak stack traces, and security headers like HSTS and CORS are set sensibly. Where documentation is missing we reconstruct it from traffic so the team ends up with a working OpenAPI spec and a clean findings report.
We regularly test REST, GraphQL, SOAP, gRPC, and WebSocket APIs, along with API gateways, microservices, third party integrations, and webhook endpoints. GraphQL tests focus on batching abuse, introspection exposure, and field level authorization, while gRPC engagements include reflection checks and metadata token handling. Internal APIs that sit behind a VPN can be tested through a jump host or temporary staging environment.
A typical API security assessment for 50 to 100 endpoints takes 5 to 10 business days, while larger microservice estates run 2 to 3 weeks depending on roles and business flows. Deliverables include an executive summary, a technical report with reproduction steps and proofs of concept, a tracker spreadsheet for developers, and one round of free retesting after fixes. Critical findings are shared the same day they are confirmed so production risk is contained quickly.
