About Byte Defense
A cybersecurity training initiative built for Bangladesh — designed to meet global standards.
The problem
Bangladesh has one of the fastest-growing tech workforces in South Asia, but cybersecurity education hasn't kept pace. Most people learn from scattered YouTube videos, outdated blog posts, or international certifications that cost more than a month's salary.
There's no structured path. No local mentorship. No community. You're on your own.
What we do differently
Every Byte Defense course is a live cohort. That means real sessions on Zoom with an instructor who knows the room — not a pre-recorded video from 2019. You ask questions, share your screen, and get feedback in real time.
Our curriculum is built around doing, not watching. When a session covers SSRF exploitation, you're exploiting SSRF. When we teach Maltego, you're running graphs on real targets. By the end of a cohort, you should be able to do the work — not just describe it on a resume.
Who's behind this
Byte Defense is built by DentiSystems — a technology company focused on practical tools and education for the security industry. Our instructors are active practitioners: bug bounty hunters, security consultants, and OSINT specialists who teach from experience, not textbooks.
We're based in Dhaka, operate remotely, and accept local payment methods because we believe world-class training shouldn't require an international credit card.
