The Updated Guide to IT Certifications: Find Your Path to a Successful Tech Career

What Are IT Certifications?

IT certifications are credentials awarded to individuals who show proficiency in specific areas of information technology. They validate technical skills, knowledge, and expertise in various IT disciplines, such as networking, cybersecurity, cloud computing, and software development.

IT certifications have become a benchmark for competence in the tech industry. They are issued by professional organizations, vendors, or educational institutions.

Types of IT Certifications

IT certifications fall into two main categories: vendor-specific and vendor-neutral. 

Vendor-specific certifications relate to a particular company's technologies or products. Examples include Microsoft's Azure certifications, Amazon Web Services (AWS) certifications, and Cisco’s CCNA. These certifications are better suited for professionals working directly with those technologies. 

On the other hand, vendor-neutral certifications focus on broader IT concepts and skills. CompTIA's Security+, Project Management Professional (PMP), and Certified Information Systems Security Professional (CISSP) are some popular examples. These are versatile and find use in a lot of platforms and industries.

Why Should You Pursue IT Certifications?

We aren’t exaggerating, but pursuing IT certifications is one of the best career moves you can make. These are excellent additions to your resume—they increase your value and make you more appealing to employers.

When you complete certifications, you show the world that you have dedicated time and effort to master the skills in your resume beyond the bare minimum. This alone makes you a standout candidate in job markets.

But there’s more to it:

• Certifications signal expertise. They validate your knowledge in specialized areas like cloud computing and cyber security.

• Certified employees are seen as more efficient and skilled. Certified IT staff add $30,000 worth of value per year organizations. annually

• Employers prefer certified professionals because it reduces the need for extensive training.

Certifications are also faster and often cheaper to obtain compared to traditional degrees. For example, a cybersecurity certification might take months, while a degree could take years. 

Plus, it opens up the scope for salary increases—nearly 60% of IT professionals received raises in 2022,  with 17% attributing it directly to earning a certification.

Top IT Certifications to Consider in 2025

Without going too much into technicalities, we have picked these broad-ranging IT certifications to launch your career.

How to Maintain Certifications?

Earning an IT certification is just the first step. To keep your skills relevant, many certifications need maintenance or renewal. This is to keep certified professionals up to date with new technologies, industry practices, and standards.

Most certifications come with an expiration date, usually ranging from 2 to 3 years. For example:

• CompTIA certifications: Valid for 3 years.

• AWS certifications: Require renewal every 3 years.

• Cisco certifications must be renewed every 3 years. You can take recertification exams or earn Continuing Education credits.

One common way to maintain certifications is by earning Continuing Education Units (CEUs). These are credits you can collect by attending webinars, completing training courses, or even teaching others in your field. Many certifying bodies, like CompTIA and (ISC)², offer CEU programs that let you renew without retaking exams.

IT Certifications: The Proper Way to Say 'I Know What I’m Doing' 

Although we have tried our best to cover the best certifications in the most important IT fields, we also had to exclude some really good ones.

Before choosing a certification, take your time to figure out what you want out of it and how it will impact your career. Don’t spend months on a certification that isn’t even going to help your professional career, or in something you aren’t even interested in.
