A guide to penetration testing certifications, including what they are, why they're valuable, and the best pen testing credentials for your cybersecurity career path.

This post will be updated annually with the top pen-testing certificates.

Penetration testing - a.k.a. “pentesting” - involves simulating attacks on networks and computer systems to identify vulnerabilities which can then be shored up by the cybersecurity team. Pen testing is a vital component of an organization’s information security strategy.

Pen testing certifications are professional credentials earned by IT security specialists who demonstrate a level of proficiency in this field. The leading pen-tester certificates are offered by various types of institutions, including cybersecurity industry associations, globally recognized certifying bodies, and technical training providers.

In this post, we will identify the best penetration testing certifications by experience level and specialization. For each certificate, we’ll highlight the key skills it covers, prerequisites, costs, benefits, training options, and more.

After a 2022 that saw massive layoffs in the high-tech workforce, 2023 is heralding more of the same.

ITCareerFinder analyzes the latest data on tech salaries, employment, cost of living and quality of life to uncover the best cities for IT professionals to call home.

Many of the best computer jobs can now be done remotely, but plenty of tech roles still come with a commute. And even if you work from home, where you live shapes what you earn, what you spend and how much you enjoy life after hours. This study compares 74 U.S. metro areas with at least 10,000 computer and math jobs to find the best places to live in or relocate to as an IT professional.

To rank the best cities for tech jobs, we weighed what tech pros actually take home after local prices, how many tech jobs each metro offers and how concentrated they are, and quality of life, because after all, once the 9-to-5 is over you still have to live there.

ITCareerFinder highlights some of the most popular and accomplished women in computer science.

Women account for only 19% of computer science graduates in the US, according to the latest data from the National Center of Education Statistics. This disparity is confirmed by an extensive study from the Allen Institute for AI which place the rate of male to female computer scientists at 4:1.

Despite representing a small percentage of the CS workforce, female computer scientists have made some revolutionary contributions to the field. These achievements are made doubly special because women have historically had far less access to education and employment.

This page will spotlight the great women of computer science and outline some of their key accomplishments.

Here are the 5 most famous female computer scientists:

There's a wide range of scholarships for aspiring tech pros; here are some of the most interesting and valuable.

Information technology is among the most lucrative and opportunity-rich domains in the modern workforce, and a college degree is the best way to get a leg up in this competitive field. However, in today’s economy, paying for school can be challenging. Thankfully, there’s a variety of scholarships that can help you fund a world-class education in CS (computer science), IT (information technology) and STEM (science, technology, engineering and mathematics) disciplines.

We scour the web, evaluate and reevaluate the most dynamic scholarships with the biggest payouts to find the best awards for students pursuing a career in IT. Most of the scholarships on this list are tech-focused, but we’ll also feature some undeniable awards that can be applied to any field. Some contests only accept applicants from a certain demographic or socioeconomic group - in these cases, we’ll outline those requirements in the scholarship’s description.

Here are our favorite scholarships for computing and information technology majors:

ITCareerFinder breaks down the most sought-after tech jobs you can get with a degree in computer science. Delve into each role for marketable courses, salaries, recommended degree programs and insider tips.

There’s never been a better time than now to pursue a career in IT. The proliferation of emerging technologies in mobile and cloud computing, soaring demand for data science, programming and cyber security skills, and the increased automation (for better or worse) of legacy roles in retail and manufacturing, are just some of the factors driving a golden age for tech employment. There are infinite paths to the IT job of your dreams, but whichever road you choose there’s a good chance that earning a degree in computer science (CS) will be your first step.

CS curricula and the jobs you can land with a computer science degree vary widely, but there are some core subjects shared by most undergraduate computer science programs. The core curriculum in a CS associate or bachelor’s degree typically includes programming and software development, data structures and algorithms, operating systems, and applied mathematics. There are many CS specializations that dive deeper into one or more of these core areas, and plenty of computer science majors designed to prepare you for a specific IT career path. Your personal passions, resources like time and money, and the job you’re shooting for will dictate the computer science program that’s right for you.

The curriculum in a graduate computer science program builds on the undergrad coursework above. Generally, a computer science master’s degree dives deeper into the technical skills you learned as an undergrad, with a greater focus on a specific career track and potential management roles. MBAs in computer science concentrate on the business side of things; here you will learn to use computing skills to set and achieve organizational goals. Doctoral and PhD degrees in computer science tend to focus on research and scientific advancement; these programs are geared toward jobs like computer research scientist and CS professor.

This article will lay out some of the best jobs you can achieve with a computer science diploma (“best” in this case means top-tier salaries, an aggressive hiring forecast, and a high rate of upward mobility). We'll also highlight the courses and electives you should pursue to maximize your job prospects in each role, recommended degree levels, and earnings.

It's hard to deny the fact that "big data" is a ubiquitous buzzword today, and every now and again someone suggests that it's just a passing fad. The fact of the matter is that, while this trend may be experiencing some hype now and will likely eventually plateau (in the distant future), it's going to be a major player from here on in no matter how you slice it. This is because the insight brought forth from analyses of vast quantities of relevant data eliminates assumption and guesswork from the business decision-making process. In large businesses especially, this directly equates to mitigated risk, colossal savings and accelerated growth.

Data from the staffing industry indicates that people aren't just talking about big data; medium and large businesses are spending a great deal on — and exhibiting a lot of interest in — the scouting and hiring of data scientists and developers in the big data space.

The demand speaks for itself: for every one developer looking for a job in big data there are 3.6 job postings available in the United States. Additionally, as of 2014, developers who work with big data languages are the highest paid in the space. R, the statistical analysis programming language tops the list with an average salary over $115,000. Other languages and frameworks designed for dealing with large data sets, such as NOSQL, Apache Hadoop and MapReduce, boast six-figure salaries as well.

Even small businesses reap benefits from big data: although they don't often have the need to substantiate hiring in-house big data developers, they gain an advantage through externally managed analytical dashboards that help them visualize data and spot trends that can influence smarter businesses decisions.

The bottom line is that big data isn't simply an over-hyped term in the tech space and business world. The infatuation with big data is supported with fiscal interest in this new field because of the marked difference it's already making for SMBs and enterprises, and the vast potential it has to impact the way do business going forward.
