18 Certifications Worth Having

By Ryan Day


A certification is more than a gold star. It’s more than a pat on the back or a “job well done.”

Obtaining a professional certification is an indication that you’re an expert. It’s proof to employers, peers and even yourself that you speak and think in a specific language. It comes with the expectation that co-workers and decision-makers will call on you for advice and insight. Your experience and expertise will be key to a business’ growth in the face of internal and external changes.

Basically, a certification is confirmation that you provide value. And in a competitive and crowded industry like IT, it’s often not easy to stand out.

This is your chance.

Deciding to get certified is one thing. Selecting a certification is another. What do you want out of it? A promotion? A higher salary? Viable skills?

With hundreds of certifications to choose from, how do you know which one is the best fit for you? Which ones are popular? Which ones have staying power?

In terms of standing out, just one certification may not be enough. Globally, IT professionals hold an average of about three certifications apiece. And many are already planning their next one. Overall, 64% of IT professionals are either presently engaged in training for a certification or plan to in the ensuing year. Now that’s some competition.

Whether you’re wading into the waters with a foundational credential or pulling all-night study sessions to prep for your six-hour CISSP exam, a lot of time and energy goes into certification. Here are 18 options, in no particular order, that are worth your effort based on site searches, feedback from instructors and data in the Global Knowledge IT Skills and Salary Report.


1. AWS Certified Solutions Architect – Associate

I wonder if Amazon Web Services could have even envisioned the global demand for cloud when they launched their certification program just four years ago. Today, AWS certifications are wildly popular and produce some of the highest salaries in the industry.

AWS Certified Solutions Architect – Associate has been the standard bearer for cloud professionals, especially as many organizations have fully invested in AWS cloud services. In the IT Skills and Salary Report, it’s the highest-paying certification in the United States and Canada ($117,773).

This associate-level certification is a perfect fit for IT pros looking to fill the cloud hiring void. According to our report, 29% of decision-makers are struggling to hire cloud professionals. With cloud standing firm as a top tech interest area worldwide, that skills shortage isn’t likely to drop on its own.

With AWS dominating the cloud scene, AWS-specific expertise is often mandatory. And the positions pay extraordinarily well, which is why AWS certifications will likely remain in strong demand.

Take a deeper dive into this certification with our prep guide, “A Complete Guide: How to Become an AWS Certified Architect.”

2. CCNA Routing and Switching

Of the 16,000-plus respondents to our IT Skills and Salary Survey, nearly 16% own a Cisco Certified Network Associate (CCNA) Routing and Switching credential. It’s a foundational dive into the skills needed to plan, implement, verify and troubleshoot complex network solutions.

It’s no surprise that this is one of our most sought-after certifications since the cloud and changing technologies, such as quality of service (QoS) elements and wireless controllers, put an emphasis on networking importance. With mobile devices multiplying and the emergence of the Internet of Things (IoT), the skills required of a core network engineer are constantly evolving. This certification fills the skills gaps that occur when technology outpaces training.

The demand and staying power of this certification sets it apart. It’s also a necessary step toward achieving a CCNP Routing and Switching credential.

3. PMP® — Project Management Professional

If you want to talk about staying power, PMP® has been in the mix since 1984 and is as prevalent as ever. This certification is one of the most prestigious. Even after 34 years, it still means a lot.

Aside from its staying power, PMP® is a great credential to have if you’re trying to move from a technical to a managerial track. Thus, PMP®-certified professionals have higher-than-normal salaries, especially when paired with an existing credential. For example, when paired with an AWS certification, the average salary is up $30,674. When paired with a security credential, the salary increases by $26,515. Similar bumps exist when coupled with ITIL®, Red Hat® and Microsoft certifications.

Another reason PMP® is so widely-respected is its exam—it’s one of the toughest tests in the industry. The exam tests five areas relating to a project’s life cycle and it’s not specialized to any particular industry. Requirements include a four-year degree and at least three years of project management experience, with 4,500 hours leading projects and 35 hours of project management education. This certification certainly requires a motivated professional who is up to the challenge.

How to prep for the exam:


4. CompTIA Network+

CompTIA Network+ is so well-respected that Microsoft, Cisco and other brands have included it as part of their certification tracks. It’s a stepping stone to more intensive and vendor-specific certifications.

CompTIA Network+ proves a technician’s competency in managing, maintaining, troubleshooting, installing and configuring basic network infrastructure. Since its launch in 1999, more than 235,000 people have become certified.

It currently ranks 18th in our top-paying certifications. It’s recommended that candidates are also certified in CompTIA A+ and have at least nine months of experience in network support, administration or education.

5. CompTIA Security+

There is a critical need for qualified security professionals. CompTIA Security+ is an ideal first step for aspiring cybersecurity experts. All IT professionals, regardless of specialty, could benefit from this foundation-level, vendor-neutral certification.

CompTIA Security+ is our 10th highest-paying certification worldwide. Candidates are required to have at least two years of experience as an IT administrator with a focus on security and have day-to-day information security experience. A CompTIA Network+ certification is also recommended.

With the addition of cloud and an increase in the complexity and frequency of data breaches, organizations are more concerned with security than ever before. This certification provides the knowledge necessary to anticipate, react to and guard against cyberattacks.

How to prep for the exam:


6. ITIL® Foundation

This entry-level certification is a win-win for individuals and organizations since ITIL-certified professionals are paid well and are better prepared to align business needs with the IT department.

ITIL Foundation helps you understand the IT lifecycle. Certified professionals are in the driver’s seat when it comes to supporting business outcomes and managing risk. Often, ITIL-certified professionals are at the forefront when an organization changes the way it does business.

Aside from its business benefits, ITIL Foundation has the 19th-highest salary worldwide, while averaging $87,453 in the U.S. and Canada. It also significantly magnifies other credentials you may currently have. When paired with a Cisco certification, the average salary increases by $13,333. Couple an ITIL certification with a project management certification, such as COBIT, TOGAF or PMI, and average salary bumps up $11,428. Similar increases occur when ITIL is paired with CompTIA, Microsoft and security credentials.

How to prep for the exam:


7. CCNA Security

Looking to combat and mitigate security threats in a Cisco network? Then this is the certification for you. CCNA Security validates your skills in developing an infrastructure and recognizing vulnerabilities in your network.

CCNA Security is held by 17% of IT professionals and is also a necessary requirement when working toward a CCNP Security credential, which has an average salary of over $100,000.

Just like all Cisco certifications, this credential is valid for three years. A CCENT certification or ICND1 v3.0 - Interconnecting Cisco Networking Devices, Part 1 is recommended before pursuing your CCNA Security certification.

Know your goals before selecting your next certification

If you want to drive change, make sure you train with a goal in mind. Don’t just randomly select a certification from this list. Training for the sake of training isn’t enough. Map out your objectives and work toward them.

Just because a certification is popular doesn’t mean it’s the right fit for you. These 18 certifications are tried and true, but do they match your desired career path? Will they help you provide immediate value and drive change in your business?

Also, make sure you understand the value of cross-certification. For instance, Microsoft, CompTIA and ITIL credentials pair well with Cisco certifications. Broadening your expertise across multiple vendors can be a great way to distinguish yourself in the workplace.

According to our IT Skills and Salary Report, nearly 47% of respondents say they train specifically to prepare for certification. A decade ago, that number was 9%. The value of certifications are no longer questioned. The only question is which one is right for you?
