Daniel Púa is an offensive security leader with 8+ years of hands-on experience in bug bounty, penetration testing, and security consulting across web, mobile, APIs and embedded systems, currently heading security at Magnific (formerly Freepik). He builds and runs end-to-end security programs—threat detection, incident response, WAF/EDR deployments and automated vulnerability workflows—while keeping security aligned to business goals. A seasoned CTF competitor and member/mentor of Spain’s ECSC team, he blends competitive exploit skills with practical engineering, authoring popular tools like nomore403 (1.6k+ stars), debugHunter and pwny.cc that embody his “if it parses, it breaks” mindset. Based in Málaga, he combines leadership and research: still active as an independent security researcher for bug bounty and pentest engagements, and an organizer in the local infosec community.
