Comprehensive api penetration testing services by Nextwebi to Strengthen Your Defenses

At Nextwebi, we offer modern API security testing services that go far beyond traditional protections like API gateways and web application firewalls (WAF), which often provide only partial coverage and a false sense of security. Our expert team delivers end-to-end testing solutions that give you full visibility into your APIs — enabling secure coding practices, identifying vulnerabilities early, securing third-party integrations, and protecting production environments. By focusing on the full lifecycle of API security — from development to deployment — we help businesses build scalable, resilient, and compliant systems that are ready to withstand today’s evolving cyber threats.

Through comprehensive api security testing, organizations can easily identify and address security loopholes in their APIs. We excel in evaluating authentication and authorization mechanisms, input validation methods, error handling practices, rate limiting, and other vital aspects. Our professionals use advanced tools and methodologies and perform best security practices for protecting critical data and resources.

There are different types of API security testing that Nextwebi offers, such as Dynamic API Security Tests, Static API Security Tests, and Software Composition Analysis. Our expert API security testers are proficient in using the latest tools like Postman, Burp Suite, OWASP ZAP, SoapUI, and others to automate the detection of security vulnerabilities, functional errors, and performance issues in APIs to ensure their robustness and reliability

Our Range of API Security Testing Services

Nextwebi's API security testing services protect your APIs from threats, identify vulnerabilities, and ensure data security. We provide reliable solutions to secure both new and existing APIs, keeping your business safe and compliant.

Input Validation Testing

We verify that your API is capable of handling user input to avoid cyber threats like SQL injection, cross-site scripting (XSS), and buffer overflows.

Static API Security Tests

We use static analysis security tools to analyze the source code of the application to detect potential vulnerabilities.

Dynamic API Security Tests

Our team excels in running active (dynamic) tests against your API endpoints. If anyone is looking to develop powerful API security testing, integrating dynamic testing with static API security testing and SCA is an optimal way to do so.

Software Composition Analysis (SCA)

We use advanced tools for SCA, in which we compare the dependency tree of your application and match it against a database of known vulnerabilities to ensure the API doesn’t inherit security flaws from external code.

Authentication & Authorization Testing

We assess the effectiveness of authentication mechanisms like OAuth and JWT, as well as authorization protocols, for preventing unauthorized access.

Security Configuration Review

Our team efficiently reviews the API configuration, CORS settings, permissions, and other factors to ensure they are secure.

Learn More
01
Threat Designing

We begin the testing procedure by decomposing the system, systematically enumerating threats, and based on that, preparing a detailed threat profile for analyzing it deeply.

02
Vulnerability Detection

Once the threat profiles are ready, we launch an automated scan, eliminate false positives in the system, and perform manual detection to identify vulnerabilities.

03
Vulnerability Analysis

We then jump straight into conducting a risk analysis, through which we prioritize the risks to resolve, that are covered under industry security standards.

04
Reporting

After the vulnerability detection and analysis, we develop technical reports and management summary reports, and conduct a comprehensive report walkthrough.

05
Support

At the final phase, we provide technical support to developers on fixes and monitor all issues until closure.

Frequently Asked Questions

Here are a few frequently asked questions, if you have anything in mind feel free to reach out to our team, we are available just a call, email & WhatsApp.

API penetration testing should be conducted whenever there’s a major upgrade, a new integration, or at least once a year. Regular testing ensures that as your API evolves and new vulnerabilities emerge, it remains secure.
API testing typically identifies vulnerabilities such as weak authentication, poor encryption, inadequate data validation, and misconfigured endpoints. Addressing these issues quickly is vital to prevent unauthorized access and data breaches.
API penetration testing helps you identify hidden vulnerabilities in your APIs before hackers do. It ensures that your APIs, which act as gateways to your data, are secure from risks such as attacks, unauthorized access, and data breaches, thereby protecting both your business and customer trust.
The cost of API penetration testing depends on the API's complexity and the number of endpoints tested. It typically ranges from ₹30,000 to ₹2,00,000. While more complex APIs or those with many integrations may cost more, it is a crucial investment to prevent costly security breaches.
API penetration testing is like a security drill for your app's connections. It simulates cyberattacks to test the APIs that enable systems to communicate, identifying vulnerabilities such as unsafe data transfers or improper access controls before hackers can exploit them.
In API security testing, protection against DDoS attacks is achieved through strong firewalls, traffic monitoring, IP filtering, and rate limiting. These methods help detect fake requests and unusual traffic patterns, keeping the API safe from overload attacks and ensuring it stays available.
Techniques like OAuth, API keys, JWT (JSON Web Tokens), and basic authentication are used to secure APIs. These methods ensure that only authorized users can access the API and their identity is properly verified before granting access.
Common security risks to APIs include SQL injection, cross-site scripting (XSS), broken authentication, insecure API endpoints, bypassing rate limits, and data leaks. These vulnerabilities can lead to unauthorized access, data breaches, and system exploitation.
Use secure methods for authentication (like OAuth), validate inputs, set rate limits, encrypt data in transit, and regularly check for vulnerabilities to improve API security. Also, apply access controls, handle errors properly, and ensure compliance with security standards.
API security testing involves finding endpoints, identifying risks, spotting vulnerabilities, performing penetration tests, retesting, and fixing any weaknesses to keep the API safe from attacks.
API security testing is needed to find weaknesses, protect sensitive data, prevent unauthorized access, and ensure the quality of applications. It also ensures compliance with security standards, helping protect against attacks.
