TryHackMe takes a more structured approach to cybersecurity training than Hack The Box. It offers guided learning paths that walk you through topics step by step, with explanations and hints along the way. You can start from complete beginner and work up to more advanced penetration testing. The platform uses virtual machines in the browser, so you don't need to set up any local infrastructure. Each room includes tasks, questions, and sometimes a mix of reading and hands-on practice.

It's particularly good for people who are new to security and want a clear path forward. The difficulty ramps gradually, and the community is helpful. There's a free tier with a good amount of content and a paid subscription for full access. If you're considering a career in cybersecurity, it's a solid place to start.
