You don’t need to wander here and there looking out for a good course that will teach you all at an affordable price point except for Intellipaat’s Cyber Security Certification course.
You could join this course to gain proficiency in mastering the cybersecurity tools and get proficient in it by doing the industry-based projects which are included in the course package itself.
Also, I would suggest you to watch our YouTube video on what is cybersecurity?
