Our API Testing Service identifies security vulnerabilities in your APIs, protecting your business from data breaches, system disruptions and compliance risks.
APIs (Application Programming Interfaces) are the backbone of modern digital interactions, facilitating seamless communication between software systems, web applications, mobile apps, and more. However, as APIs grow in importance, they also become prime targets for cyber criminals. This is why thorough API testing is essential to maintaining the security and integrity of your business’s digital infrastructure.
At Sentaris, we offer comprehensive API penetration testing services designed to uncover vulnerabilities that could expose your business to significant risks.
API Testing, particularly penetration testing of APIs, is a highly manual and time-consuming process that requires a deep understanding of the API’s structure and functionality. Unlike web applications, which can often be tested through automation, APIs are more complex. There is no standardised format to anticipate what an API request will look like, making each test unique and requiring extensive attention to detail.
At Sentaris, we begin the process by gathering detailed information about the API you want tested. This often includes requesting Swagger documentation or similar resources, which help us accurately construct queries to interact with your API in the same way a legitimate user or potential attacker would. This is essential to ensure that we are testing the API in a way that reflects its real-world usage.
Once the queries have been constructed and we’ve built the appropriate authentication mechanisms, we begin testing the API for vulnerabilities. Our testing includes a detailed analysis of both business logic vulnerabilities and technical vulnerabilities, such as those identified in the OWASP Top Ten (e.g., injection flaws, broken authentication, and improper data validation).
Sentaris’ highly experienced security consultants have tested some of Australia’s largest and most complex systems, ensuring you receive expert guidance. Our approach combines automated testing with a strong emphasis on manual assessment, targeting high-risk areas for a comprehensive analysis. We go beyond traditional methods, identifying high-risk business logic issues to provide a thorough and cost-effective solution.
With our expertise, you can strengthen your security posture and protect your critical assets.
APIs often handle sensitive data, such as user information, financial transactions, and proprietary business data. By identifying and addressing security flaws, you protect this critical information from exposure.
If an attacker exploits a vulnerability in your API, they can disrupt the flow of data between systems, potentially causing downtime, loss of functionality, or other operational disruptions. API testing ensures that your systems remain stable and secure.
Many industries require businesses to protect the data handled by their APIs. Testing helps you meet compliance standards like GDPR, PCI DSS, and APRA CPS 234, reducing the risk of legal penalties.
APIs often play a vital role in the operation of your business processes. Testing helps ensure that your APIs are not only technically secure, but also free from business logic flaws that could allow attackers to exploit them in unexpected ways.
The rapid pace of API adoption means that many businesses are building and deploying APIs faster than they can secure them. Regular testing helps your business stay one step ahead of evolving threats, preventing potential exploits before they occur.
At Sentaris, we take a systematic approach to API testing that focuses on both technical vulnerabilities and business logic flaws. Here’s how we do it:
API testing is not just a recommendation—it’s a necessity for any business that relies on APIs to function. Whether you’re developing new APIs or maintaining existing ones, Sentaris can help ensure that they are secure, resilient, and ready to face evolving cyber threats.
