Hear From Those Who’ve Transformed Their Careers

We’re proud to have trained many successful cybersecurity professionals through personalised mentorship and coaching, industry-led curriculum, and practical hands-on experience.

"No Hustle Culture – Just Real Growth" I came for interviews but stayed for the open, thoughtful mentor chats. Mentors share real industry insight or follow up when they don’t know – it’s refreshing. The training is intense but builds solid foundations for advanced topics. When I was close to burnout, my mentor encouraged a break – that changed everything. CyLynk genuinely cares and adapts support to your personal situation. – Gispa Walstab."
