As answered by people managing PentesterLab and OnlySecurity.
OnlySecurity's answer:
It specialises in hands-on hardware and physical security (locks, RFID, Flipper Zero, Hak5, IoT radio), which most training platforms barely cover, and many of its courses are taught by the companies that make the tools.
OnlySecurity's answer:
Learners can start for free and learn skills they can show, through badges, a leaderboard and a portfolio recruiters can verify. Trainers get a non-exclusive licence and keep 75% to 90% of net sales with processing fees absorbed, where larger marketplaces can pay instructors far less after fees.
OnlySecurity's answer:
Penetration testers, red teamers, physical security assessors, RFID and IoT researchers, and hobbyists learning hardware hacking, plus security practitioners who want to teach and earn from their own courses.
OnlySecurity's answer:
OnlySecurity grew out of KSEC, a UK supplier of security research hardware. Customers kept asking how to get the most out of tools like the Proxmark, Flipper Zero and Hak5 gear, so KSEC started building practical courses alongside the hardware. That became an open platform where practitioners and hardware vendors teach, and where learners compete, train, learn and share.
