API PT
Protect the backbone of your applications, your APIs, by closing security gaps that expose sensitive data
We go beyond automated scans; our focus is on identifying high-impact vulnerabilities and uncovering issues that traditional tools and other vendors often miss. Using advanced hybrid testing approach combined with strategic automation with manual deep-dive testing, delivering comprehensive, high-impact results tailored to your unique environment. Our PT methodology is based on industry standards such as API penetration testing, OWASP, and it includes rigorous REST API penetration testing to ensure your APIs are protected against the latest attack techniques—helping safeguard sensitive data and prevent unauthorized access.

Penetration testing is a proactive cybersecurity assessment designed to identify vulnerabilities and provide clear guidance on how to fix them before they can be exploited. By simulating real-world attacks, we help evaluate and strengthen your security posture.

API penetration testing focuses on evaluating the security of application programming interfaces (APIs), which are often a prime target for attackers. Whether you’re securing mobile backends, third-party integrations, or microservices, mobile app API penetration testing plays a critical role in identifying and mitigating risks.

FAQ
Penetration testing should be performed at least annually or after major system updates, infrastructure changes, or security incidents. High-risk industries may require more frequent testing.
A vulnerability assessment is an automated scan that identifies known security weaknesses but does not actively exploit them. A penetration test goes further by manually testing and exploiting vulnerabilities to assess their real-world impact and severity.
To ensure an effective test, we typically require:
Scope definition – A clear understanding of the systems, applications, or networks to be tested.
Access credentials – For authenticated testing, if applicable.
Test environment – Optional, if you prefer not to test in production.
Point of contact – A designated team member to address questions and receive findings.
Penetration testing is carefully planned to minimize disruptions. We coordinate testing times, use controlled attack methods, and can conduct assessments in a non-intrusive manner to avoid system downtime. If preferred, we can also test lower environments (such as staging or development) instead of production, reducing the risk of impacting live operations.
Yes, we offer retesting services to verify that vulnerabilities have been properly remediated. This ensures your security improvements are effective before closing findings.
A penetration test typically takes 2 to 6 weeks, depending on the number of assets being tested, their size, and complexity.
