10 cybersecurity certifications to boost your career in 2021

Written by Steve Zurier in December 2020

Heading into 2021, cybersecurity remains one of the enterprise’s highest priorities as companies continue to support remote working conditions imposed by the COVID-19 pandemic. And demand for cybersecurity experts shows no signs of slowing. The Bureau of Labor Statistics has projected that employment of information security analysts will grow 31% from 2019 to 2029, faster than the average for all occupations.

For those looking to advance their cybersecurity careers or break into the field, cybersecurity certifications can help in landing jobs, boosting careers or ensuring against a job loss — provided you choose wisely. Our guide provides insight into the 10 cybersecurity certifications deemed most valuable for aspiring and seasoned cybersecurity professionals:

  1. CompTIA Security+;
  2. (ISC)2 Certified Information Systems Security Professional (CISSP);
  3. (ISC)2 HealthCare Information Security and Privacy Practitioner (HCISPP);
  4. ISACA Certified Information Security Manager (CISM);
  5. EC-Council Certified Ethical Hacker (CEH);
  6. EC-Council CEH (Practical);
  7. CompTIA PenTest+;
  8. Offensive Security Certified Professional (OSCP);
  9. Cloud Security Alliance (CSA) Certificate of Cloud Security Knowledge (CCSK); and
  10. vendor-specific security certifications.

In building this list of top 10 cybersecurity certifications, we talked to a broad range of people in the security industry. We heard from course providers and consultants, such as Cybrary and CyberVista; talked to a professor from University of Maryland Global Campus; sought advice from security providers, such as Cisco and Fortinet; and contacted the leading trade groups and certification providers, such as CSA, CompTIA, EC-Council, ISACA, (ISC)2, Global Knowledge and Offensive Security.

The list starts off with basic, entry-level and management track certifications and then moves on to the offensive security certifications for hands-on penetration testers (pen testers) and certified ethical hackers. It concludes with a mini 10 list of top vendor-specific certifications. Security professionals typically need a mix of all three types of certifications: management training, hands-on and vendor-/product-specific knowledge.

CompTIA Security+

Most security pros say that IT support technicians and admins — or people looking to get into the security field — should start with the CompTIA Security+ certification.

Upon completing the Security+ certification, students will have the skills and knowledge required to install and configure systems used to secure networks, applications and mobile devices. They will also be prepared to take part in risk mitigation activities, perform and respond to threat analysis, and work with knowledge of all applicable laws, policies and regulations. The exam consists of 90 multiple-choice and performance-based questions. Students have 90 minutes to complete the exam. The exam focuses heavily on performance-based questions. The performance-based emphasis ensures that trainees can troubleshoot quickly and accurately. Passing the exam requires a score of at least 750 out of 900.

Cybersecurity workforce gap shrinks

There’s some good news this year for employers on the cybersecurity workforce gap from (ISC)2, the nonprofit organization that provides security training and certifications.

A November 2020 report on workforce trends found that the global gap has decreased from 4 million cybersecurity workers in 2019 to 3.1 million in 2020. In the United States, the workforce gap shrank from 498,000 to 359,000, with a rest-of-world gap of 2.7 million.

For those looking to advance their security careers or break into the field, the findings are in no way a disincentive: The industry continues to need millions of good people who are not afraid of hard work, enjoy problem-solving and can handle the day-to-day pressures of working in a cyber situation.

EC-Council Certified Ethical Hacker (CEH)

Certified Ethical Hacker (CEH) understands and knows how to look for weaknesses and vulnerabilities in target systems and uses the same knowledge and tools as a malicious hacker but in a lawful and legitimate manner to assess a target’s security posture. The CEH credential, offered by EC-Council, certifies people in the specific network security discipline of ethical hacking from a vendor-neutral perspective.

The CEH credential was developed for the following reasons: establish and govern minimum credentials standards for professional information security specialists in ethical hacking; inform the public that these credentialed individuals meet or exceed the minimum standards; and reinforce ethical hacking as a unique and self-regulating profession. Applicants must have two years of provable work experience in the security field to qualify. The exam runs four hours and consists of 125 questions.


Jobs held by CEHs

  • auditor
  • security professional
  • site administrator
  • network infrastructure manager

EC-Council CEH (Practical)

CEH (Practical) consists of a six-hour exam that requires students to demonstrate the application of ethical hacking techniques to solve a security audit challenge. Skills tested include threat vector identification, network scanning, OS detection, vulnerability analysis, system hacking and web app hacking. Students typically take this exam after they have attained the CEH certificate.

Students are given limited time, just like in the real world. The exam was developed by a panel of experienced subject matter experts and includes 20 real-life scenarios with questions designed to validate essential skills required in the ethical hacking domains as outlined in the CEH program. It’s not a simulated exam, but rather, it mimics a real corporate network through the use of live VMs, networks and applications, designed to test skills. Students are presented with scenarios and asked to demonstrate the application of the knowledge acquired in the CEH course to find solutions to real-life challenges. Student pass with a score of 70% and above.

CEH (Practical) certificate holders have mastered the following skills:

  • understand attack vectors;
  • perform network scanning to identify live and vulnerable machines in a network;
