Candidates should understand how policies, standards, and procedures are developed and enforced across an organization. While this is not a purely technical domain, it is one that all security professionals must engage with regardless of their specific role or area of specialization.

Performance Based Question Preparation

Performance-based questions are among the most challenging aspects of the Security+ exam for many candidates, particularly those who have primarily studied through reading and memorization. These questions present simulated environments where candidates must complete tasks such as configuring firewalls, identifying vulnerabilities in network diagrams, or matching attack types to appropriate mitigations. They require applied knowledge rather than simple recall.

Preparing for performance-based questions requires hands-on practice with security tools and concepts in lab environments. Platforms such as TryHackMe, Hack The Box, and CompTIA’s own CertMaster Labs provide structured exercises that build the practical skills needed for these question types. Candidates who invest time in lab practice consistently report feeling more confident during the exam and tend to perform better on performance-based sections than those who rely on passive study alone.

Recommended Study Materials

A wide range of study materials is available for Security+ candidates, making it important to select resources that align with the SY0-701 exam objectives specifically. The CompTIA Security+ Study Guide by Mike Chapple and David Seidl is a popular choice for its comprehensive coverage and accessible writing style. Professor Messer’s free video course is another highly recommended resource that many candidates use as a primary or supplementary learning tool.

Practice exams from providers such as Dion Training, Jason Dion on Udemy, and CompTIA’s official CertMaster Practice platform are invaluable for identifying knowledge gaps and building test-taking familiarity. Flashcard tools like Anki help reinforce terminology and concepts through spaced repetition, which is particularly useful for the dense vocabulary covered in the General Security Concepts and Governance domains. Combining multiple resource types produces a more thorough and confident preparation experience.

Experience and Background Needed

CompTIA recommends that candidates have at least two years of IT experience with a security focus before attempting the Security+ exam. Holding CompTIA Network+ beforehand is also strongly advised, as a solid understanding of networking concepts is assumed throughout much of the Security+ content. Candidates without this background often find certain domains, particularly Security Architecture and Security Operations, significantly more challenging.

That said, motivated candidates who lack formal experience can still succeed by supplementing their study with hands-on lab practice and structured learning paths. Many self-taught professionals have earned Security+ through disciplined preparation alone. The key is ensuring that theoretical study is always accompanied by practical exposure, whether through home labs, cloud sandbox environments, or entry-level IT roles that provide regular contact with security tools and concepts.

Department of Defense Requirement

One of the most significant factors driving the value of Security+ in 2025 is its approval under Department of Defense Directive 8570 and its successor framework, DoD 8140. This directive requires that all personnel performing information assurance functions within the DoD hold approved baseline certifications, and Security+ is among the most widely accepted credentials across multiple categories of this framework.

This requirement creates consistent and substantial demand for Security+ among contractors, military personnel, and federal agency employees working with sensitive government systems. For professionals seeking to enter or advance within the defense and government contracting sector, Security+ is often a non-negotiable credential rather than simply a preferred one. The DoD connection gives Security+ a level of institutional backing that few other entry-to-mid-level certifications can claim.

Salary and Career Impact

Professionals who hold the CompTIA Security+ certification consistently report positive career outcomes, including higher starting salaries, faster promotions, and access to a broader range of job opportunities. Common roles associated with this credential include security analyst, systems administrator with security responsibilities, network security engineer, and IT auditor. These positions offer compensation that sits comfortably above the general IT industry average.

In 2025, the cybersecurity talent shortage continues to drive strong demand for certified professionals at all experience levels. Security+ serves as a reliable signal to employers that a candidate has verified foundational knowledge, which can be the deciding factor in competitive hiring situations. For early-career professionals in particular, earning Security+ before or shortly after entering the workforce establishes credibility that accelerates career development in meaningful and measurable ways.

Certification Renewal Process

The CompTIA Security+ certification is valid for three years from the date it is earned and must be renewed through the CompTIA Continuing Education program to remain active. Renewal requires accumulating 50 Continuing Education Units over the three-year period through approved activities such as completing higher-level exams, attending industry conferences, publishing security-related content, or completing relevant training courses.

Many professionals find that the renewal process naturally aligns with their ongoing professional development activities, making it less of a burden and more of a structured accountability framework. Passing a higher-level CompTIA exam such as CySA+ or CASP+ automatically satisfies the renewal requirement for Security+ as well, which incentivizes continued certification advancement. Allowing the credential to lapse and retaking the full exam is always possible but is considerably more time-consuming and expensive than maintaining it proactively.
