Common Questions

Frequently Asked Questions

Is it legal to learn ethical hacking?
Yes — ethical hacking on systems you own or have explicit written permission to test is completely legal. Platforms like TryHackMe and HackTheBox provide legal practice environments.
What VPN do you recommend for privacy?
Mullvad and ProtonVPN are our top picks. Both have completed independent audits, have clear no-log policies, and don't require personal information to sign up.
How do I start learning cybersecurity from scratch?
Start with our Beginner's Roadmap — it covers networking fundamentals, Linux basics, and then moves into security concepts with free resources.
Do I need to know coding to work in cybersecurity?
Basic Python and Bash scripting help, but many cybersecurity roles (incident response, GRC, security analysis) don't require advanced programming skills.
What certifications are worth getting in 2025?
CompTIA Security+ for beginners, then OSCP for penetration testers or CISSP for senior security professionals. We have a detailed certification guide.
