Difficulty

Higher than Security+

Moderate (if well-prepared)

Key challenges

More technical depth (packet analysis, log analysis, SIEM, forensics)Longer exam (106–180 questions, up to 5 hours)Open book: Requires strategic note organization rather than memorizationMore real-world security applications (command-line tools, packet analysis, etc.)

Covers a broad range of topics but not in deep technical detailMultiple-choice & some performance-based questions (PBQs can be tricky)Time constraint (up to 90 questions in 90 minutes)

Who finds it hard

Those without hands-on security experienceThose who struggle with time management (due to the long exam)

Those new to IT and networkingThose who struggle with memorization and scenario-based questions

Technical and hands-on Covers deep technical topics such as cryptography, network security, and incident responseProvides real-world, hands-on skills useful in cybersecurity roles

Requires recertification every 4 years GSEC is valid for four years and requires continuing education credits or a renewal fee to stay certified. In comparison, Security+ requires renewal every three years, and CISSP requires only ongoing CPE credits.

Highly respected in cybersecurity Recognized by government agencies, military and top employersHolds more weight than general entry-level certifications like Security+

Not as commonly known for general IT positions While highly respected, GSEC isn’t as widely recognized as Security+ in general IT job postings. Some employers might require CISSP or CEH instead.

DoD 8140/8570 approved Meets US Department of Defense requirements for cybersecurity jobs

Expensive The GSEC exam cost around $2,499 (includes training), so it is more expensive than Security+ or CEH.

Broad coverage of cybersecurity topics Covers access controls, cloud security, threat detection, risk management and security incident handling 

No direct specialization While it covers many cybersecurity topics, it lacks a strong focus on a specific domain like ethical hacking (CEH) or risk management (CISM).

Good for career growth Opens doors to roles like security analyst, incident responder and security engineerA strong stepping stone for advanced certifications (CISSP, GPEN, OSCP) 

Challenging exam Requires in-depth knowledge of cybersecurity topics, making it harder for beginnersOpen-book format, but still requires strong understanding and preparation

No prerequisites Unlike CISSP, GSEC can be obtained without work experience.

Widely recognized & industry-standard One of the most recognized entry-level cybersecurity certificationsAccepted by major employers, including government agencies and private companies

Lower earning potential Advanced certifications (CISSP, GSEC, OSCP) often lead to higher salaries, so most professionals will need to pursue further certifications for career growth.

No prerequisites No prior experience or certifications needed to take the exam

Requires recertification every 3 years Needs continuing education credits (CEUs) or a renewal fee

Approved for DoD 8140/8570 roles Meets US DoD requirements for cybersecurity jobs

Too basic for experienced IT professionals If you already have IT security experience, Security+ may not add much value. Professionals may benefit from skipping it and going for GSEC, CEH or CISSP instead.

Covers a broad range of security topics Provides a well-rounded foundation for cybersecurity careers by covering topics like network security, threat intelligence, cryptography, incident response, risk management and compliance.

Less technical and hands-on Security+ is more theory-based and foundational, lacking the deep hands-on skills in GSEC or CEH.

Good for career entry and growth Can help land jobs like security analyst, soc analyst, or network administratorServes as a stepping stone for higher certifications (CISSP, CEH, GSEC, etc.)

Competitive job market Many candidates have this certification, making job competition tougher. Accordingly, work experience or certifications like CEH, CISSP or GSEC may be needed to stand out

Vendor neutral Not tied to a specific company (e.g., Cisco, Microsoft), so the knowledge applies across different IT environments

Affordable Exam cost is just $392, which is far less than GSEC’s $2,499.

You want a more technical, hands-on certification GSEC is ideal for those looking to specialize in security engineering, incident response or penetration testing.

You’re new to cybersecurity Security+ is best for beginners or IT professionals making their first step into security.

You’re pursuing a career in government or defense GSEC is highly valued in military, government, and DoD-related jobs

You’re aiming for compliance with DoD 8570/8140 for government roles Security+ is often the minimum requirement for DoD cybersecurity jobs.

You already have IT security experience and want to level up The focus on advanced topics is helpful for IT professionals transitioning into security roles.

You want a certification that quickly helps with job opportunities Many entry-level cybersecurity jobs require or prefer Security+.

You have the budget for a premium certification The GSEC training and exam costs $2,499, but the in-depth training and knowledge can justify the investment.

You need an affordable, widely recognized certification Security+ is budget-friendly ($392) and is commonly requested by employers.
