The average time-to-hire for a CISSP holder is 30 days. For someone with no information security certification, it's closer to 90. That gap—and the salary difference behind it—is why so many people are looking at this space right now.
But "get certified" is advice that stops too early. There are roughly 40 recognized information security certifications on the market. Picking the wrong one—too advanced, wrong domain, wrong employer recognition in your region—costs you a year of study and exam fees you won't recover. This guide cuts through the catalog and tells you what's actually worth pursuing based on where you are now and where you're trying to go.
What an Information Security Certification Actually Signals
Employers use certifications as a filter, not a guarantee of competence. What they're really screening for is:
- Domain alignment — Did this person study the right sub-field? A GRC-focused cert won't impress a penetration testing team.
- Commitment signal — Sitting a multi-hour proctored exam under real conditions separates people who read a few blog posts from those who put in 200+ hours.
- Employer recognition — Some certs are household names in government contracting (Security+, CISSP). Others are better known in financial services (CISM). Others are respected in technical circles but unknown to HR (OSCP).
Understanding this framework helps you pick. You're not choosing the "best" information security certification in the abstract—you're choosing the one that matches a specific employer, a specific job title, and a specific stage in your career.
The Main Information Security Certification Tracks
Entry-Level: CompTIA Security+ and Google Cybersecurity Certificate
Security+ is the most widely referenced entry-level information security certification in US job postings. It's DoD 8570 compliant, which means it's a hard requirement for many federal contractor roles. If you're looking at government work, defense contractors, or managed security service providers, start here. Study time is typically 60–80 hours for someone coming from a general IT background.
The Google Cybersecurity Certificate (available on Coursera) is a newer entrant aimed at career changers with no IT background. It won't substitute for Security+ in most job requirements, but it's a legitimate ramp-up path and costs substantially less to pursue.
Mid-Level: CISSP and CISM
CISSP (Certified Information Systems Security Professional) is the most recognized advanced information security certification globally. ISC2 administers it. The exam covers eight domains from security architecture to software development security. The experience requirement—five years in at least two of the eight domains—means you can't fake your way into this one.
CISM (Certified Information Security Manager) from ISACA overlaps with CISSP in prestige but tilts toward governance, risk, and program management rather than technical architecture. If you're moving toward a CISO or security director role in a financial institution, CISM is often the more targeted credential.
Technical/Offensive: CEH and OSCP
EC-Council's Certified Ethical Hacker (CEH) sits in an awkward middle ground—widely listed in job postings, but often criticized by practitioners as too theoretical. It's worth pursuing if an employer's job listing calls for it specifically, or if you're in a region where OSCP is less recognized.
OSCP (Offensive Security Certified Professional) is the gold standard for penetration testing roles. It's a 24-hour hands-on exam where you actually compromise machines. There's no multiple choice. Employers who know security respect it more than any other offensive cert—but it requires serious technical depth before you attempt it.
Audit and Compliance: CISA and Systems Auditing
CISA (Certified Information Systems Auditor) is the dominant information security certification for audit, compliance, and risk management roles. If you're coming from accounting, finance, or internal audit, this is often the most direct route into a security-adjacent role with strong compensation. The exam is ISACA-administered and covers five job practice domains focused on IS audit process, governance, and systems acquisition.
How to Choose: A Decision Framework
Run through these four questions before you commit to any information security certification path:
- What job title are you targeting in 18 months? Security analyst, penetration tester, security architect, GRC analyst, and CISO all have different cert preferences. Don't certify generically.
- What's your current experience level? Attempting CISSP without the required experience is a waste. Spending 12 months on Security+ when you already have five years in security operations is equally wasteful.
- What sector are you targeting? Federal/defense = Security+, CISSP. Financial services = CISM, CISA. Tech companies = OSCP, AWS Security Specialty. Healthcare = HCISPP.
- What's your prep budget and timeline? OSCP lab time costs real money. CISSP study materials and exam fees run $800–$1,200 before you factor in prep courses. Cheaper isn't always worse, but some certs require investment.

Salary and Career Outcomes by Certification
Certifications do move salaries, but the delta varies significantly by credential and role:
- CompTIA Security+: median compensation in the $65K–$85K range for entry-level security analyst roles in the US
- CISSP: median around $120K–$145K for security architects and senior engineers; CISSP holders consistently appear in the top compensation band in ISC2's annual workforce survey
- CISM: competitive with CISSP in financial services; often required at the VP-of-Security / CISO level
- CISA: median $95K–$110K for audit and compliance roles; strong in Big 4 consulting and financial services
- OSCP: penetration testing roles typically range $100K–$130K at mid-level; the cert commands a premium in offensive security specifically
These ranges reflect US market data. Adjust expectations for other markets—UK, Canada, and Australia have similar relative premiums but different absolute numbers.
Common Mistakes When Pursuing an Information Security Certification
Starting with the hardest cert to sound impressive
People register for CISSP with two years of experience and fail, wasting exam fees and discouraging themselves. The experience requirement exists for a reason. If you don't meet it, get Security+ and spend the next three years in a role that qualifies you, then sit the CISSP.
Treating the cert as the endpoint
A certification is a door-opener, not a career. Employers screen for certs to decide who to interview. After that, it's your practical knowledge and problem-solving that matter. Study to understand the material, not to pass the exam. The difference shows up in technical interviews.
Ignoring recertification requirements
CISSP, CISM, and CISA all require continuing professional education (CPE) credits to maintain active status. Factor this into your long-term planning. A lapsed certification is often worse than none—it signals you stopped engaging with the field.
Assuming one cert is enough
Most security professionals above the analyst level carry two or three certifications across different domains. A CISM + CISA combination is common in GRC. A Security+ + CEH combination is a reasonable mid-career package for someone in security operations who isn't going deep into offensive work.
FAQ
Which information security certification should I get first?
For most people starting in security: CompTIA Security+ if you have any IT background, or the Google Cybersecurity Certificate (Coursera) if you're coming from a completely different field. Both are recognized by entry-level employers and provide a foundation for more advanced certifications later. Don't start with CISSP or CISM—those require documented experience you probably don't have yet.
Is an information security certification worth it without a degree?
Yes, particularly in security. The field has a documented skills shortage, and many employers explicitly substitute certifications for degrees in job requirements—especially for roles in security operations, penetration testing, and compliance. CISSP and CISM holders without degrees work at senior levels in most major organizations. The combination of certifications + a strong portfolio (GitHub, CTF competition results, home lab documentation) can fully substitute for a traditional CS degree in many hiring contexts.
How long does it take to get an information security certification?
It depends heavily on the certification. Security+: most candidates with IT background are exam-ready in 8–12 weeks at part-time study. CISSP: plan for 4–6 months of serious preparation, plus the experience requirement. CISA: 3–4 months of prep is typical. OSCP: 3–6 months of lab work plus the exam, which is a 24-hour hands-on assessment. Don't rush these—failed exams have waiting periods and retake fees.
What's the difference between CISSP and CISM?
CISSP (ISC2) is broader and more technically oriented across eight domains including cryptography, architecture, and software security. CISM (ISACA) is specifically focused on managing and governing security programs from an executive perspective. CISSP is more common in technical leadership roles; CISM is more common in business-side security management and financial services. Both require five years of experience. If you're technical and want to keep one foot in architecture, lean CISSP. If you're moving toward CISO or security program director, CISM is often the more direct path.
Can I prepare for an information security certification entirely online?
Yes. Every major certification offers official study materials and practice exams online. Third-party prep courses on Coursera and Udemy cover CISSP, CISM, and CISA thoroughly. OSCP is the one exception that requires hands-on lab work—but even that is delivered through an online lab environment. In-person bootcamps exist but aren't necessary; the exam is the same regardless of how you prepared.
How much does an information security certification cost?
Exam fees alone: Security+ runs approximately $400, CISSP approximately $750, CISM approximately $760 for ISACA members ($575 for members), CISA similar pricing. Add prep course costs ($100–$500 depending on platform and format), official study guides ($50–$100), and practice exams ($40–$80). Total first-attempt investment typically runs $500–$1,500 per certification. Budget for a possible retake—failure rates on CISSP and CISM are not trivial.
Bottom Line
The information security certification that moves your career is the one that matches where you're going, not the one with the most impressive acronym. If you're starting out: Security+. If you have five years in security and want to move into leadership: CISSP or CISM depending on whether you're staying technical or moving into management. If you want to specialize in audit and compliance: CISA is the clear choice and pairs well with the Information Systems Auditing, Controls and Assurance course to build the foundational knowledge the exam expects.
Pick one track, build the experience it requires, and study the material to actually understand it—not just to pass. The employers worth working for can tell the difference in the interview.
