Ethical Hacking Courses

One of the biggest draws on is our committment to ethical hacking. Our community regularly discusses these topics, including best cybersecurity practices and ways to test a network. In the Udemy sale, we found a notable course on password penetration testing. That's a fundamental in the world of ethical hacking. The course is called Learn Wi-Fi Password Penetration Testing (WEP/WPA/WPA2).

GPT and Productivity Courses:

Many students want courses on prompt engineering and AI-based productivity. Udemy's sale has that covered too. We found the following GPT courses in the sale.

Mastering OpenAI Python APIs: Unleash ChatGPT and GPT4

By definition, a course on OpenAI must be relatively new. The organization’s popular ChatGPT chatbot launched last year and exploded in popularity in 2023. So it makes sense for students to learn about the topic with a Udemy course.

What caught our eye? With only about 5,600 students enrolled, this is still one of the smallest courses we’ve evaluated. Our research shows an exceptionally high rating and robust coverage of the topic. 

At the time of review, Udemy students gave this 4.8 out of 5 stars. The thing that makes this course unique is the promise that it will help you build a GPT-4 chatbot. That’s a real-world project that could help students win jobs.

This course lists at $19.99 and fell to $14.99 when we checked at the start of the biggest sale of last season. Check here for today's price.

The course lists at $74.99, but we found it on sale for $14.99 during the popular spring-season sale. We anticipate the course may fall below this price during Black Friday or Cyber Monday's sales this year.
