FAQs on Cybersecurity Essentials Course

Will I be able to get a cybersecurity job after CS100?Collapse

CS100 provides a foundation, not job-ready expertise. Most entry-level cybersecurity roles require additional training and certifications (CompTIA Security+, CEH). We recommend CS100 as a starting point to assess if cybersecurity is right for you, then pursue our CS Nanodegree programme or additional certifications for job-ready skills.
