API Security Testing

API Security Testing.

AllSafe provides comprehensive API security testing in India against the OWASP API Security Top 10 2023 — covering REST, GraphQL, SOAP and gRPC APIs. Our OSCP-certified testers focus on the business logic vulnerabilities and access control flaws that make API breaches so damaging — BOLA, broken object-level authorisation, mass assignment, and rate limiting bypass that automated scanners consistently miss.

  • OWASP API Security Top 10 2023 — BOLA, mass assignment, broken auth and all 10 categories.
  • REST, GraphQL, SOAP, gRPC and WebSocket APIs all in scope.
  • Business logic flaws, excessive data exposure and improper assets management.
  • Free re-test of every fixed finding — always included.

What You Will Get

A complete API security assessment covering authentication, authorisation, input validation, rate limiting, and business logic across every endpoint. Every vulnerability is manually verified with a working proof-of-concept showing real-world exploitability.

Broken Object Level Auth (BOLA)

The most critical API vulnerability -- testing every endpoint for unauthorised access to other users' data through object ID manipulation.

Broken Authentication

JWT algorithm confusion, weak token entropy, missing token expiry, credential stuffing on login endpoints, and API key exposure analysis.

Mass Assignment

Testing for undocumented parameters that can elevate privileges or modify data that should be read-only -- a common flaw in auto-serialised API frameworks.

Rate Limiting & Resource Exhaustion

Missing or bypassable rate limits on authentication, OTP, password reset and data export endpoints -- enabling brute force and enumeration attacks.

GraphQL-Specific Testing

Introspection exposure, query depth abuse, field suggestions, batch query attacks and GraphQL-specific injection vulnerabilities.

CVSS Report & Re-Test

CVSS v3.1 rated findings with HTTP request captures, reproduction steps and developer remediation guide. Free re-test included. Regulator accepted.

Our Testing Methodology

  • API Discovery & Inventory

    We enumerate every API endpoint -- documented and undocumented -- across REST, GraphQL, SOAP and gRPC. Postman collections, Swagger specs and traffic capture used to build a complete endpoint inventory.

  • Authentication & Authorisation Testing

    Every endpoint tested for BOLA, broken function-level authorisation, JWT algorithm confusion, missing rate limits and privilege escalation between all user roles -- the most critical API attack categories.

  • Injection & Logic Exploitation

    Mass assignment, excessive data exposure, SQL and NoSQL injection via API parameters, SSRF through API endpoints and GraphQL-specific attacks including depth abuse and batch query exploitation.

  • CVSS Report in 48h

    Every finding CVSS v3.1 scored with full HTTP request and response captures, reproduction steps and developer-grade remediation specific to your API framework. Delivered in 48 hours.

Choose Your Testing Depth

Type 01

Black Box

Zero prior knowledge — simulating a real external attacker with no credentials, no documentation and no code access.

Best for

Organisations wanting a realistic external attacker simulation to validate perimeter defences.

Recommended

Type 02

Grey Box

Standard user credentials provided. Tests authenticated and unauthenticated attack surfaces simultaneously for maximum coverage.

Best for

Most organisations. The most comprehensive coverage for the cost — our recommended default engagement.

Type 03

White Box

Full access including source code and architecture documentation for maximum depth and coverage of your entire codebase.

Best for

Organisations needing maximum depth or where regulators mandate a code-level review alongside VAPT.


Why API Security Testing Is Non-Negotiable

APIs are now the primary attack surface for web applications. BOLA alone accounts for the majority of serious API breaches — and it is invisible to automated scanners. Our OSCP-certified testers manually probe every endpoint to find the access control and business logic flaws that automated tools consistently miss.


OSCP-Certified Testers

Every API assessment led by a certified human tester. We simulate a real attacker probing your endpoints -- not a scanner running a checklist.

OWASP API Top 10 2023

Full coverage of all 10 OWASP API Security categories -- BOLA, broken auth, mass assignment, excessive data exposure and more.

GraphQL Specialist Testing

Introspection exposure, batch query abuse, field suggestion attacks and GraphQL-specific injection testing included as standard.

Business Logic Coverage

BOLA, broken function-level authorisation, mass assignment and excessive data exposure -- the access control flaws that make API breaches devastating and are invisible to automated tools.

Authenticated and Unauthenticated Testing

Every endpoint tested across all user roles -- anonymous, standard user, administrator and any custom roles. Privilege escalation between roles is a primary focus of every API engagement.

Undocumented Endpoint Discovery

We discover and test endpoints that are not in your Swagger or Postman collection -- shadow APIs, legacy endpoints and internal APIs often contain the most critical vulnerabilities.


The Cost of an Unsecured API

APIs are the fastest-growing attack vector in India. A single BOLA vulnerability in a financial API can expose every customer’s account data. The average Indian data breach now costs Rs 17.9 crore — before DPDPA 2023 penalties that can reach Rs 250 crore per incident.

Frequently Asked Questions

Do you need API documentation?

API documentation (Swagger, Postman collection, OpenAPI spec) is helpful but not required. Our testers are experienced at discovering and mapping API endpoints without documentation — often finding undocumented endpoints that are not covered by documentation-driven testing.

Can you test authenticated API endpoints?

Yes. We test both unauthenticated and authenticated endpoints. For authenticated testing we require test credentials at each privilege level — standard user, administrator, and any other roles your API supports. We test for privilege escalation between all role levels.

Are your reports accepted by RBI, SEBI and IRDAI?

Yes. Our audit reports are structured to meet the specific submission requirements of the relevant regulatory framework — including the Reserve Bank of India, SEBI, IRDAI, and all other major Indian regulators. We have a 100 percent acceptance record across all regulatory submissions.

Do you test internal APIs?

Yes. With VPN access or a test environment we can test internal APIs that are not internet-facing. Internal API security is frequently overlooked and often contains the most critical vulnerabilities as developers assume internal traffic is trusted.

Do you guarantee zero false positives?

Yes. Every finding in our report has been manually verified and proven exploitable with a working proof-of-concept. We never submit raw automated scanner output. If a scanner raises an issue that cannot be confirmed through manual testing it is excluded entirely from the final report.

What happens after we fix the vulnerabilities?

A free re-test is included in every engagement. Once you have remediated the findings, our OSCP-certified testers re-verify every fix to confirm it is effective. We then issue a security closure certificate valid for regulatory and client submissions. The re-test must be used within 60 days of the original report delivery.
