API Security Testing is to identify, classify and exploit potential vulnerabilities in Application Programming Interfaces (API) and Web Services. Security Assessments aids the developers to timely remediate the vulnerabilities, enhance its overall security and safeguard the software from any unauthorized access which can cause a negative impact on the organization.

API Security Testing

APIs expose application logic and sensitive data such as Personally Identifiable Information (PII) and hence the vulnerability. Advancements in the web technologies have increased the use of the API owing to their capability in providing ease in usage of the software technologies.

Hence assessments like API security testing as per OWASP API Top 10 2019, helps the developers to remediate vulnerabilities that may cause a potential impact on the organization or on business.


  • Information Gathering

    Post scope definition, we enumerate the API to gain information about the potential vulnerabilities.

  • Reporting

    Document detailed report listing from the classified findings in a clear, concise and effective manner.

  • Vulnerability Analysis and Exploitation

    We identify the vulnerable input parameters of the API through automated as well as manual testing and exploit it.

  • Confirmatory Assessment

    APIs are re-tested to validate the applied fix after remediation for the identified observations.

  • Post-Exploitation

    We assess the value of the compromised API, to determine whether any further exploitation is possible.

  • Final Reporting

    Based on the test results of the confirmatory assessment, a Pass/Fail report is issued.


API security testing is a continuous improvement process securing the data and the reputation of the firm and the user. The benefits of API security testing run far and help businesses meet their compliance requirements faster.

Standing from a cybersecurity point of view we provide a concise and comprehensive report that details all the necessary aspects of your application that needs to be improved. Our API security testing program provides the following benefits:

  • Possible prevention of hacking attacks.

  • Identification of API security issues before the bad guys.

  • Ease to adhere to any compliance regulations and standards.

  • Better assurance towards application security.

frequently asked questions

OWASP API Top 10, SANS 25, NIST,PCI and all applicable industry standard security frameworks are the usual standard documents that are followed for VAPT of APIs.

Best Scanning Practice includes performing all scans and re-scans within 30 days. Also, organizations should deploy all vulnerability patches having Critical and High severity in 15 days. If organizations are unable to fix any vulnerability within 30 days, then the particular vulnerability is to be reported, so that the alternative controls to mitigate the risk could be applied and the organizations can conduct assessment for the particular finding in the next scan.

It takes 4-5 days to complete the test (might vary depending upon the number of API’s) and 1-2 days for the reporting.

The API Security Test report consists of the following:
• The report defines a detailed risk description for every reported vulnerability.
• The report demonstrates all the identified vulnerabilities with Proof-of-Concept (POC) collected while performing the security assessment.
• The report categorizes all the reported vulnerabilities in the report into severity levels such as ‘Critical,’ ‘High,’ ‘Medium’ & ‘Low’ depending on the risk and the potential business impact it may cause due to vulnerability exploitation.
• Recommendations for the effective mitigation and closure of the identified vulnerabilities are assigned and mentioned in the report.
• Usually, only those vulnerabilities that are identified on the date of the assessment are reported and no vulnerabilities will be reported that are present before or after the period of the assessment.
