We launch your program and reach out to our committed crowd of hackers, attracting top talent to your bounty program with consistent and coordinated attention. Our community of hackers starts searching for vulnerabilities. Vulnerabilities are submitted and managed via our Coordination platform. Reports are reviewed and triaged by the HackenProof team (or by yourself), and then passed on to your security team for fixing. Our bug bounty platform allows you to get continuous information (ongoing security for your app) on the condition of security of your company. Independent security researchers can also report any breaches found in a legal manner.

Modern software development must be as fast as the business. The modern AppSec toolbox lacks integration, which creates complexity that slows down software development life cycles. Contrast reduces the complexity that hinders today's development teams. Legacy AppSec uses a single-size-fits all approach to vulnerability detection and remediation that is inefficient, costly, and expensive. Contrast automatically applies the most efficient analysis and remediation technique, greatly improving efficiency and effectiveness. Separate AppSec tools can create silos that hinder the collection of actionable intelligence across an application attack surface. Contrast provides centralized observability, which is crucial for managing risks and capitalizing upon operational efficiencies. This is both for security and development teams. Contrast Scan is a pipeline native product that delivers the speed, accuracy and integration required for modern software development.

You can either submit API test requests through the user interface form or trigger the EthicalCheck API using tools like cURL or Postman. To input your request, you will need a public-facing OpenAPI Specification URL, an authentication token that remains valid for a minimum of 10 minutes, an active license key, and your email address. The EthicalCheck engine autonomously generates and executes tailored security tests for your APIs based on the OWASP API Top 10 list, effectively filtering out false positives from the outcomes while producing a customized report that is easily digestible for developers, which is then sent directly to your email. As noted by Gartner, APIs represent the most common target for attacks, with hackers and automated bots exploiting vulnerabilities that have led to significant security breaches in numerous organizations. This system ensures that you only see genuine vulnerabilities, as false positives are systematically excluded from the results. Furthermore, you can produce high-quality penetration testing reports suitable for enterprise use, allowing you to share them confidently with developers, customers, partners, and compliance teams alike. Utilizing EthicalCheck can be likened to conducting a private bug-bounty program that enhances your security posture effectively. By opting for EthicalCheck, you are taking a proactive step in safeguarding your API infrastructure.
