From Ethical Hacker to Serial Founder | Francisco Nina Rente | Cyber Security District Podcast - Cyber Security District | Lyssna här

What does it take to build a cybersecurity company not once, but twice from the ground up?

In this episode of Cyber Security District, we sit down with Francisco Nina Rente, one of Portugal's most accomplished cybersecurity entrepreneurs. Francisco started his journey as a teenager tinkering with computers and quickly found his way into ethical hacking and open-source security communities. That curiosity became a career, which then led to a company.

His first venture grew from a university incubator into a 250-person operation delivering services across 22 countries, before being acquired by a global security group. After years scaling that business from the inside and taking on roles as country manager, CTO and board member, Francisco stepped away to build again.

This time, the mission is clearer: help organisations stop just detecting threats and start truly recovering from them. Art Resilia was born out of a conviction that the market was shifting from cybersecurity to cyber resilience, and Francisco positioned the company right at the centre of that shift.

Key Takeaways:

Cyber resilience is about recovery, not just defence
Focus beats opportunity-chasing, especially in the early days of a startup
The Commonwealth of a team always comes before individual interest
Trust-based security communication outlasts fear-based selling every time
Knowledge remains the core differentiator, even in the age of AI
