Chuck Keith: How NetworkChuck Made IT a YouTube Career

Somewhere right now, a help-desk tech is studying for a certification exam while a bearded man tells them to learn it RIGHT NOW. That man is Chuck Keith, better known as NetworkChuck, and his YouTube channel has become one of the biggest doors into IT on the planet.

The numbers are absurd for a channel that started with Cisco collaboration tutorials: more than 5.4 million subscribers, 627 videos and roughly 435 million views by October 2026, plus a coffee brand, an online academy and a cloud browser for threat researchers.

The origin is smaller and more human. Keith learned networking from a training company's videos, posted his own to a few hundred people, and answered every single comment until the trainer he'd learned from got in touch.

Chuck Keith at a Glance

• Keith started his IT career studying with CBT Nuggets videos, earning his Cisco CCNA Routing and Switching, CCNA Voice and CompTIA Security+ certifications.
• He launched the NetworkChuck channel on April 27, 2014, with Cisco collaboration tutorials, because, as he put it, "I saw a need for it."
• The channel grew from 500 to nearly 17,000 subscribers on a simple policy: "I answered every comment and question."
• In March 2018 CBT Nuggets introduced him as its newest trainer, after Jeremy Cioara, one of the trainers he'd learned from, found his channel and reached out.
• In 2019 Cisco featured him and David Bombal as "tech YouTube stars" in its Cisco Champions program.
• His site's subscriber count climbed from 370,000 around 2020 to 1.5 million in 2021 and 2.8 million by 2023, and he launched a line of coffee blends for IT professionals along the way.
• Today NetworkChuck runs an academy and a cloud browser alongside the channel, and in 2025 Keith joined a Bitdefender podcast on AI threats, from prompt injection to voice-clone scams.

The Life of Chuck Keith

Learning From the Nuggets

Keith's path into IT ran through other people's videos. "I started my IT career with training from CBT Nuggets," he says in his trainer bio, crediting the company's Cisco expert Jeremy Cioara and networking specialist Keith Barker for the instruction that got him certified.

He earned Cisco's CCNA Routing and Switching, the CCNA Voice for phone and collaboration systems, and CompTIA's Security+. He went to work in networking and collaboration, the branch of IT that keeps corporate phones and video systems running.

He also grew a beard. It'd matter later.

Answering Every Comment

On April 27, 2014, he created a YouTube channel called NetworkChuck and started posting Cisco collaboration tutorials. The motivation was practical: "I saw a need for it," he told CBT Nuggets, adding, "I didn't want to find training videos... I wanted to find out how people were studying."

The channel didn't explode. It crawled, from about 500 subscribers to nearly 17,000 over four years, and Keith credited one habit above all: "I answered every comment and question."

Over time the channel's focus shifted from collaboration tutorials to IT career advice and certification study tips, and the motivational, caffeinated NetworkChuck persona took shape.

Hired by His Teachers

Then the teacher found the student. Cioara came across the channel and got in touch, and after an interview process CBT Nuggets hired Keith as a full-time trainer, introducing him to its learners in March 2018 as the newest member of the team.

He learned the craft of making training the way he'd learned networking: from Keith Barker, who hosted him at his house to teach him how the company built its courses.

His philosophy for the job was already set. He wanted to "tie together the technical material with a message of motivation and taking control of your career," and he defended certifications as proof "you can study, learn, and then validate that you know something." He had, he noted, been growing the beard for about three years, and jokingly attributed "all my success to the beard."

Hack Your IT Career

The next few years turned a side channel into a brand. In May 2019 Cisco's newsroom spotlighted Keith and fellow YouTuber David Bombal as "tech YouTube stars" and members of its Cisco Champions program.

His website settled on a mission statement it still uses: "NetworkChuck is dedicated to helping you hack your IT career," whether you want to be a network engineer, a hacker or a cloud engineer, or just get your first job. By 2020 the site counted more than 370,000 subscribers. A year later it was 1.5 million, and "inspired by his YouTube following," he'd launched a line of coffee blends for IT professionals.

Some of his biggest videos are career guides. "The hacker's roadmap," his map of how to get started in IT, has been viewed 2.4 million times in its 2023 edition, and his nearly two-hour help-desk walkthrough has passed 1.3 million. Adafruit's blog shared his 2021 tutorial on building a malicious USB device from an $8 Raspberry Pi Pico.

Beard, Coffee, Tech, YouTube

By 2023 the channel had 2.8 million subscribers and the site was selling courses: "Get started with a career in I.T. with courses from Network Chuck." The NetworkChuck Academy grew into a catalog of guided programs, including a CCNA course with video lessons, Cisco IOS labs and quizzes, and a course on network design and communication models that was free until April 10, 2026.

He added a cloud browser aimed at threat researchers who want to browse "securely and anonymously," and a store for the coffee. His Linktree bio reduces the whole enterprise to four words: "Beard. Coffee. Tech. Youtube."

The Sheriff's Call

Over the years his subjects widened from certifications to hacking and, lately, AI. In September 2025 he joined a Bitdefender podcast on how AI is reshaping cybercrime, from prompt injection to voice cloning.

He noted that a video he made about virtual machines roughly six years earlier was "still, to this day, one of my top-performing videos," and said he was "working on a video right now about hacking AI and prompt injections."

The scam problem had reached his own family. "My mom got a call from the local sheriff saying they were looking for my sister," he said. "It was completely fabricated."

Five Million

As of October 2026, NetworkChuck has more than 5.4 million subscribers and about 435 million views, and the channel description sums him up in four words: "I LOVE Information Technology!!"

He's still uploading at pace, with recent videos on AI agents, still telling viewers to go get certified, and still, presumably, drinking the coffee.

Chuck Keith: Powered by Coffee

Keith's story is less about hacking than about teaching, and about the strange loop YouTube makes possible: a student of training videos who became a trainer, then a teacher to millions.

He still runs the channel, the academy and the coffee store under one name, and still pitches each new skill as something you need to learn RIGHT NOW.

The beard and the all-caps titles are the brand. The habit underneath them, answering every question from every beginner, is how the first 17,000 subscribers showed up.
