Prefer a free, university-backed primer before committing? Cybersecurity Fundamentals on edX lets you audit the core concepts at no cost, with a paid Verified Certificate only if you want proof of completion. It's an honest way to test your interest before spending anything.
Get certified: the credentials recruiters actually screen for
Automated résumé filters and hiring managers look for specific certifications. Two names come up again and again for newcomers, and both have current exam versions you should target directly.
CompTIA Security+ (SY0-701)
Security+ is the credential most commonly listed on entry-level security job postings, and SY0-701 is the current version — don't study for an older one. The exam runs up to 90 minutes with a maximum of 90 questions, including performance-based questions that make you solve a scenario rather than pick a letter, and you need 750 on an 100–900 scale to pass. It's vendor-neutral, which is exactly why it travels well across employers. The CompTIA Security+ (SY0-701) Complete Course & Practice Exam maps to the current objectives and pairs teaching with practice questions, which is the combination that gets people through. It's a one-time Udemy purchase, discounted often — check the live price rather than the headline.
CompTIA Network+ (N10-009)
Security sits on top of networking, and gaps in networking knowledge are where beginners lose points. Network+ (current version N10-009) proves you understand how traffic actually moves — addressing, routing, ports and protocols, and common network attacks. Plenty of people take it before Security+ for exactly that reason. The TOTAL: CompTIA Network+ (N10-009) + Practice Exam covers the full blueprint with a practice test attached. Even if networking isn't your end goal, this material quietly makes every other security topic easier.
Get hands-on: the skills that carry an interview
Certifications open the door; demonstrable skills keep you in the room. These courses build the practical muscle memory that interviewers probe for.
Learn Ethical Hacking From Scratch
Understanding how attackers operate is the fastest way to understand what you're defending. Learn Ethical Hacking From Scratch walks you through setting up a safe lab and running real techniques against machines you own — reconnaissance, exploitation, and post-exploitation — so the theory in your certification study suddenly has context. Keep it strictly ethical: practise only on systems you're authorised to test. As a one-time Udemy course it's usually inexpensive when discounted.
The Complete Cyber Security Course: Hackers Exposed!
For the defensive counterpart, The Complete Cyber Security Course: Hackers Exposed! focuses on the threat landscape and how to harden systems against it. It's a solid conceptual bridge between beginner awareness and the deeper technical work, and it pairs naturally with the hacking course above — attacker's view and defender's view of the same problem.
Getting Started with Wireshark
Reading network traffic is a genuinely differentiating skill for a junior analyst. Getting Started with Wireshark: The Ultimate Hands-On Course teaches you to capture and interpret packets — how to see, at the byte level, what a connection is really doing. It reinforces the Network+ material and gives you something concrete to talk about when an interviewer asks what you can actually do.
A sensible order to work through this
- Confirm your interest with a free or broad course — the edX fundamentals or the Google certificate's opening modules.
- Build the base by working through the Google certificate and shoring up networking with Network+ material.
- Earn Security+, since it's the credential most job filters look for.
- Get hands-on with ethical hacking and Wireshark so you have real skills to demonstrate.
Certifications get you the interview; the hands-on lab work is what gets you the offer. Budget time for both.
Keep the cost down
Most of these are one-time Udemy purchases you own forever, and they're discounted so frequently that paying full price is a mistake.
