Breaking Into Cybersecurity: Expert-Backed Tips to Launch a Career in 2025

As cyber threats surge and organizations scramble to protect digital infrastructure, the demand for cybersecurity professionals has never been higher. But for those aspiring to break into the field, the path can feel unclear. Whether you’re transitioning from IT, switching careers entirely, or just starting out, cybersecurity offers diverse entry points—but standing out requires strategy and dedication.

Caleb Mattingly is the founder of Secure Cloud Innovations. He has built an incredible reputation in the cybersecurity space, particularly for his work helping early-stage startups overcome the challenges of compliance and security frameworks like SOC 2 and ISO 27001. He joins the podcast to talk about compliance, lessons learned, threats, and pivoting to the cybersecurity field.

Here are expert-backed tips to help you launch a cybersecurity career in 2025, from mastering key frameworks like NIST 800-53 to contributing to open-source projects.

The National Institute of Standards and Technology (NIST) Special Publication 800-53 is more than a buzzword—it’s a foundational security and privacy control framework used by U.S. federal agencies and contractors.

“Understanding NIST 800-53 gives you insight into how enterprise and government-level security programs are designed,” says Caleb. “It’s not light reading, but if you’re serious about cybersecurity, it’s essential.”

Aspiring professionals should start by familiarizing themselves with the Control Families—like Access Control, Incident Response, and Risk Assessment—and review how those controls are implemented in real-world settings.

The Security Technical Implementation Guides (STIGs), published by the Defense Information Systems Agency (DISA), offer configuration benchmarks for securing systems and applications.

STIGs teach you how to harden systems against attacks, which is a key skill in operational security roles. Start by downloading STIGs for operating systems you’re familiar with—Windows Server or Linux—and try implementing recommended configurations in a virtual lab. It’s practical experience that stands out to employers, especially in government and defense sectors.

Open source is where theory meets application. Contributing to cybersecurity-related GitHub projects demonstrates initiative, technical skill, and the ability to collaborate—all traits hiring managers look for.

“Open-source contributions show more than just technical skills. They highlight how someone solves problems, collaborates, and takes initiative,” says Stephanie Holman, Technical Recruiter at MetroStar. “At MetroStar, we are leaning into this approach by exploring open-source coding challenges to uncover cleared talent. It is a great way for developers to showcase their abilities beyond a résumé.”

Look for beginner-friendly tags like good first issue or help wanted on GitHub projects in areas like intrusion detection, vulnerability scanners, or SIEM tools. Even documentation contributions can showcase value.

The CompTIA Security+ certification remains a leading entry-level credential in cybersecurity, recognized by employers worldwide. It covers core security principles, risk management, cryptography, and network security.

Many candidates now prepare using affordable online platforms like Udemy, Coursera, or Cybrary, which offer self-paced courses and practice exams.

“You don’t need a four-year degree to prove you understand cybersecurity fundamentals,” says Raymond Scott, a SOC analyst turned instructor. “Security+ helps you bridge that gap.”

Tip: Combine your Security+ study with lab practice using tools like TryHackMe, Hack The Box, or VirtualBox environments for hands-on validation.

Breaking into cybersecurity takes more than just a certification—it requires curiosity, adaptability, and a commitment to lifelong learning. Whether you’re reading STIGs or defending open-source code, every action builds the skills and mindset needed in a field that evolves daily.

The best cybersecurity professionals are problem-solvers who never stop learning. Start small, stay consistent, and keep building.
