Free IT Training Resources

What is this page about?

A catalog of the best free IT training resources by domain, arguing that quality IT education does not require paid bootcamps because major vendors and the open-source community share so much. It covers foundations (Professor Messer, Cisco Networking Academy, Google IT Support), cloud (Microsoft Learn, AWS Skill Builder), security (TryHackMe, SANS CyberAces, CISA), and DevOps and programming resources, plus YouTube channels like NetworkChuck and TechWorld with Nana, then shows how to build a complete free learning plan and where free resources fall short.

   2 flagged issues verified: an anonymous 'Network operations center analyst, career changer from hospitality industry' anecdote had no verifiable source and was de-attributed; a genuine arithmetic error was found and fixed -- the article's stated 'Total cost: $264 exam fees' did not reconcile with the individually listed exam fees in the same section ($253+$369+$100+$392+$150 = $1,264), a dropped-digit error.

   Before

   "When I decided to switch to IT, I spent the first three months using only free resources: Professor Messer for A+ and Network+, Cisco NetAcad for networking labs, and TryHackMe free tier for security basics. By the time I paid my first exam fee, I was ready. The free resources were not inferior -- they were just less organized. I had to build the structure myself." -- Network operations center analyst, career changer from hospitality industry "Total cost: $264 exam fees across 10 months." (stated total does not reconcile with the individually listed exam fees in the same section: A+ $253 + Network+ $369 + AWS CCP $100 + Security+ $392 + AWS SAA $150 = $1,264)

   After

   Many successful IT career changers spend their first few months using only free resources: Professor Messer for A+ and Network+, Cisco NetAcad for networking labs, and TryHackMe free tier for security basics, only paying their first exam fee once they feel ready. The free resources are not inferior -- they are just less organized, requiring learners to build the structure themselves. (de-attributed to plain prose) "Total cost: $1,264 exam fees across 10 months." (corrected the dropped-digit arithmetic error; $253+$369+$100+$392+$150 = $1,264)

   Why: De-attributed an anonymous 'Network operations center analyst, career changer from hospitality industry' anecdote to plain prose, since no verifiable source exists. Also found and fixed a genuine arithmetic error: the article's stated 'Total cost: $264 exam fees' did not reconcile with the individually listed exam fees in the same section ($253+$369+$100+$392+$150 = $1,264), a dropped-digit error, corrected to $1,264.
