Since 2017, we have established ourselves as a bug bounty platform specializing in web3. We assist in defining a precise scope for your project (or you can choose to do it on your own), establish an agreed-upon budget for valid vulnerabilities (with no subscription fees for the platform), and provide tailored recommendations that cater to your specific business requirements. Once your program is launched, we connect with our dedicated group of hackers, bringing exceptional talent to your bounty initiative through consistent and organized outreach. Our network of hackers begins the hunt for vulnerabilities, which are submitted and managed through our Coordination platform. Each report is assessed and prioritized by the HackenProof team (or by your team), and subsequently forwarded to your security team for remediation. With our bug bounty platform, you gain ongoing insights into the security posture of your application, ensuring continuous protection for your company. Additionally, independent security researchers are encouraged to report any discovered breaches in a lawful manner, further enhancing the security of your operations. This collaborative approach not only strengthens your defenses but also fosters a culture of transparency and trust within the cybersecurity community.

In today's fast-paced business environment, software development must keep pace with the demands of the market. However, the current AppSec toolbox often suffers from a lack of integration, leading to complexities that can impede the software development life cycle. By employing Contrast, development teams can alleviate these challenges, as it reduces the complications that frequently affect their productivity. Traditional AppSec methods rely on a one-size-fits-all strategy for identifying and addressing vulnerabilities, resulting in inefficiencies and high costs. In contrast, Contrast optimizes the application of the most effective analysis and remediation techniques, significantly enhancing both efficiency and effectiveness. Additionally, disparate AppSec tools can create operational silos, which obstruct the gathering of actionable insights related to the application's attack surface. Contrast addresses this issue by offering centralized observability, essential for risk management and leveraging operational efficiencies, benefiting both security and development teams alike. Furthermore, Contrast Scan, designed specifically for integration within development pipelines, ensures the swift, precise, and cohesive solutions that modern software development demands, ultimately leading to a more agile and responsive approach.

You have the option to send API test requests either through the user interface form or by invoking the EthicalCheck API using tools like cURL or Postman. To submit your request successfully, you'll need a publicly accessible OpenAPI Specification URL, a valid authentication token that lasts at least 10 minutes, an active license key, and your email address. The EthicalCheck engine autonomously conducts security tests tailored for your APIs based on the OWASP API Top 10 list, efficiently filtering out false positives from the results while generating a concise report that is easy for developers to understand, which is then delivered directly to your email inbox. According to Gartner, APIs are the most frequently targeted by attackers, with hackers and automated bots taking advantage of vulnerabilities, resulting in significant security incidents for many organizations. This system guarantees that you view only authentic vulnerabilities, as any false positives are systematically removed from the results. Additionally, you can create high-caliber penetration testing reports that are suitable for enterprise-level use, enabling you to share them confidently with developers, customers, partners, and compliance teams. Employing EthicalCheck can be compared to running a private bug-bounty program that significantly enhances your security posture.
