Cybersecurity Student Flies Namibia’s Flag High at International Competition

Johannes Natangwe, an Honours Cybersecurity student at NUST, has placed Namibia firmly on the global cybersecurity map following his remarkable performance at the Eschaton Capture The Flag (CTF) competition held in Kochi, India. 

Competing against more than 1 000 teams in the online qualifiers, Natangwe secured an impressive sixth-place finish to advance to the finals. The final round adopted a demanding attack–defense format, requiring participants to simultaneously protect their own systems while identifying and exploiting vulnerabilities in others; a direct reflection of real-world cybersecurity environments. 

What sets Natangwe’s achievement apart is that he competed alone. While most finalist teams consisted of four members, competition rules prevented him from adding teammates after qualification. Undeterred, he faced some of the world’s top cybersecurity talent as a solo competitor. “Competing alone was one of my biggest challenges. Be that as it may, the learning experience was remarkable, especially since I competed against highly skilled teams from around the world,” he said.

The competition proved highly competitive, with top honours going to teams from Russia and Malaysia. Yet, beyond rankings, Natangwe’s presence carried historic significance. He was the only African participant in the finals and the first from the continent to reach this stage of the Eschaton CTF. “What made this experience personally meaningful to me, was the fact that I was the only African participant in the finals, as well as the first African to reach the Eschaton CTF finals. Representing Namibia on an international stage was an honour,” he added. 

Looking ahead, Natangwe is committed to strengthening Namibia’s cybersecurity landscape. He plans to channel the skills and insights gained into mentoring fellow NUSTodians and expanding local capacity through initiatives such as Namibia’s national cybersecurity CTF competition.
