List of the Top 2 Free Bug Bounty Platforms in 2025

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.

The Open Bug Bounty initiative offers a structured and transparent platform that connects website owners with security professionals from around the globe, aiming to bolster the security of web applications for everyone's benefit. This initiative allows for coordinated vulnerability disclosures, enabling any qualified security researcher to report vulnerabilities on different sites, as long as they are discovered through non-invasive methods and follow responsible disclosure guidelines. Open Bug Bounty's role is limited to independently verifying the reported vulnerabilities and ensuring that website owners are notified through all available means. Once a notification has been sent, the website owner and the researcher can engage directly to tackle the identified vulnerability and handle its disclosure efficiently. Throughout this entire process, the initiative refrains from acting as an intermediary, thus fostering direct communication to facilitate a more effective resolution. By adopting this model, the initiative not only strengthens trust within the cybersecurity community but also inspires a greater number of researchers to actively participate in enhancing web application security, ultimately leading to a safer online environment for all users.
