CISSP vs Security+ — Which One Gets You the Interview Call in 2026

They're not competing certifications

The most common mistake people make when comparing CISSP and Security+ is treating them as alternatives. They're not. Security+ is an entry-level to mid-level cert. CISSP is senior-level and requires proof of five years' work experience. You can't substitute one for the other — and if you're early in your career, choosing CISSP over Security+ is like skipping straight to a PhD without a bachelor's degree.

CompTIA Security+ SY0-701 — who it's for

Security+ targets people with 0–4 years of security experience who want to prove foundational competency. It's a DoD 8570/8140 baseline requirement for US government and military IT security roles. It's also listed as a requirement or "preferred" qualification on a significant percentage of entry-level and mid-level SOC analyst, security administrator, and IT security engineer roles.

Average salary for Security+ holders: $65,000–$95,000 depending on role and location (2026, US market).

Study time: 30–90 days with focused daily study. The InterviUni Security+ course covers all five SY0-701 domains.

Cost: ~$392 USD for the exam voucher. No work experience required.

CISSP — who it's for

CISSP targets senior security professionals: security architects, CISOs, security managers, and senior security engineers. ISC² requires candidates to have five years of cumulative paid work experience in two or more of the eight CISSP domains. No work experience? You can still sit the exam and become an Associate of ISC² — but you can't be certified until you accumulate the experience.

Average salary for CISSP holders: $110,000–$165,000+ depending on role and location (2026, US market). CISSP consistently ranks as one of the highest-paying security certifications globally.

Study time: 3–6 months minimum. The eight domains cover 60+ hours of content. The InterviUni CISSP course covers all domains including ALE calculations, PKI, and secure SDLC.

Cost: ~$749 USD for the exam voucher, plus the experience requirement.

Which gets you the interview call?

For entry-level and mid-level roles (0–5 years experience): Security+ opens far more doors than CISSP. Most job postings at this level ask for Security+, A+, or Network+ — not CISSP. Holding CISSP with limited experience can actually hurt you in interviews because you're expected to have the seniority the cert implies.

For senior roles (5+ years experience): CISSP is often explicitly required for Security Architect, CISO, and Senior Security Manager roles. Security+ won't get you these positions — the market treats it as a prerequisite, not a differentiator.

The practical career path

• 0–2 years: CompTIA A+ or Network+ → Security+
• 2–4 years: Add a Microsoft security cert (AZ-500, SC-200, SC-300) or AWS Security Specialty
• 4–6 years: Pursue CISSP if moving into architecture or management track; CySA+ or CASP+ if staying technical
• 6+ years: CISSP, CISM, or specialisations (OSCP, GREM, GCIA) depending on direction

A note on the interview, not just the cert

Either cert gets your CV through ATS. Neither cert guarantees you'll pass the interview. The Security+ interview tests whether you can apply concepts — threat analysis, incident response, network security. The CISSP-level interview tests strategic thinking, risk management, and architecture decisions.

Practise both types with InterviUni's mock interview — the SOC Analyst and Cybersecurity Analyst roles map to Security+ level, and the IT Manager track maps to CISSP-level strategic questions.
