CISA — Certified Information Systems Auditor

What is the CISA certification?

The Certified Information Systems Auditor (CISA) by ISACA is the “gold standard” for IT audit control and assurance. This highly sought-after and high-earning certification validates your skills in information systems auditing, governance and management of IT and business resilience. CISA holders look forward to a wide range of professional and financial benefits, including a 22% potential pay boost and 70% on-the-job performance improvement. Many IT auditing jobs require candidates to have a CISA or equivalent certification to sign off on reports. It’s also a commonly held certification among managers and directors in auditing departments. CISA holders often work at major accounting firms and have successful careers as independent consultants.

Is CISA the right ISACA certification for me?

The answer to this question depends on your career goals. As Chris DeMale, ISACA Director of Channel Business Development, explains, the CISA is all about auditing.

“The operative letter in CISA is the ‘A’ for IT audit,” says DeMale. “For many organizations, the CISA is a requirement for various roles and functions.”

This makes CISA unique among the certifications offered by ISACA, the others of which are related to risk, governance, management and privacy. If you’re interested in pursuing a career as an IT auditor, public accounting auditor, IS analyst or IT audit manager, then CISA is the right certification for you.

How do I get the CISA certification?

The CISA requires five years of work experience in information systems auditing, security or control. You can substitute up to three of the five years with a combination of the below:

  • One year of information systems experience or non-IS auditing experience can be substituted for one year of work experience.
  • 60 to 120 completed university semester credit hours (the equivalent of a 2-year or 4-year degree) can be substituted for one to two years of experience.
  • A master’s degree in information security or information technology from an accredited university can be substituted for one year of experience.

CISA jobs, careers and salary

CISA is designed for early- to mid-career professionals with at least five years of experience. The certificate is ideal for practitioners who want to validate their existing skills for promotions and pay raises but who aren’t interested in pursuing management just yet. 

  • What are common CISA jobs?

    The CISA prepares you for careers related to information security auditing, risk management and compliance. CISA is also appropriate for practitioners who need access to U.S. Department of Defense (DoD) information systems, as the certification is compliant with DoD 8570 and DoD 8140.

    Some of the most common CISA job titles include:

    • Internal auditor
    • Public accounting auditor
    • IS analyst
    • IT audit manager
    • IT project manager
    • IT security officer
    • Network operation security engineer
    • Cyber security professional
    • IT consultant
    • IT risk and assurance manager
    • Privacy officer
    • Chief information officer


  • What does a CISA certification holder do?

    CISA holders have extensive expertise in assessing an organization’s data security and compliance with local regulations and laws. The audit aims to shed light on the business’s current security-related policies, procedures and systems to determine compliance and uncover weaknesses.

    During an audit, the auditor will collect an extensive amount of data from information management systems and databases and compile that information into a report. Depending on the size of the organization and the seniority of the role, the auditor may also present their findings to key stakeholders within the organization.

    IT audit reports typically include recommendations for improvement and mandatory changes to comply with regulations.

    Read Infosec’s article, Roles and responsibilities of information security auditor, for more.

  • Is CISA worth it?

    The answer to this question depends on what skills you’d like to validate and the types of roles you plan to pursue. CISA is a practitioner-focused certification with a strong emphasis on IT auditing. If you plan to work in a role where you’re “in the trenches” conducting systems audits and compiling reports, then CISA is a solid choice.

    It’s also highly respected and relatively affordable compared to other IT certifications. However, if you plan to pursue a role outside of the IT auditing and compliance space or prefer management instead of hands-on work, then another certification will probably suit your needs better.

  • What is the CISA average salary?

    With the CISA certification, you can look forward to a competitive salary and a variety of opportunities to move into senior-level and management positions. Below is a sample of CISA salary data taken from in April 2022. Keep in mind that specifics will vary based on factors like location and experience.

Paid CISA training and exam prep

When it comes to preparing for the CISA exam, you can choose to train yourself with books and free resources, or you can find a paid course. Most CISA courses fall into two categories: live online CISA boot camps or on-demand CISA courses where you go at your own pace.

Live CISA boot camps

A CISA boot camp provides days of in-depth instruction from an expert instructor. For example, Infosec partners with ISACA to provide a five-day CISA boot camp that you can take live online or in person. There are a number of other training providers that offer similar options.

The benefits of a live CISA boot camp include:

  • Live training and Q&A: You will likely have questions — and you may not know the best place to get them answered. A live instructor can set you on the right path.
  • Complete training package: Most CISA boot camps provide everything you need: instruction, exam vouchers, books, practice exams and labs. Training with a live instructor is more expensive, so when shopping around, be sure you know what’s included in your purchase — and what you’ll have to pay extra for.
  • Improved pass rates: Boot camp providers like Infosec stand by their training with an Exam Pass Guarantee. That means if you fail your exam on your first attempt, you’ll get a second attempt to pass — for free.

Self-paced CISA training

If you’re not in a hurry to earn your CISA, the go-at-your-own-pace model can be a great (and more affordable) option. These types of courses usually consist of a number of pre-recorded videos, along with practice exams and labs or exercises you can do on your own to reinforce the material.

The benefits of on-demand CISA training include:

  • Train when you want: You’re in charge of your training schedule, whether that’s daily on your lunch break or cramming all weekend long. For further motivation, you can join a study group or connect with others who are preparing for the exam.
  • Build an individual training plan: Don’t waste time learning what you already know. Since you’re not tied to a group, you can spend more time focused on the areas you need to learn most.
  • Prepare at your own pace: With on-demand training, you can take your time preparing for your CISA. Just don’t go too slow! Studies show you can quickly forget the information your’re studying — unless you’re actively using it or reviewing it.

CISA comparisons and alternatives

The CISA is one of several advanced cybersecurity certifications that you can choose from. Here’s how it stacks up against the other popular certifications you may want to consider.

  • CISA vs. CISM

    While the CISA and CISM are sometimes lumped together, the two certifications are geared towards two very different career tracks.

    The CISA is the industry standard for IT systems auditors and is geared toward professionals in hands-on practitioner roles. The CISM is a better fit for mid-and late-career professionals looking to codify their information security management expertise. CISM holders are typically managers, not practitioners. Additionally, CISA job descriptions often overlap with finance and accounting, while CISM roles are more related to program management or information assurance.

  • CISA vs. CRISC

    CRISC is an ISACA certification with a focus on enterprise-level IT risk management. The exam’s domains include IT risk identification, assessment, response, mitigation and reporting. The income potential for CRISC holders is competitive, with an average CRISC salary of $114,000.

    CRISC is an ideal fit for professionals interested in validating their IT risk management skills, while CISA is better suited for validating audit-related skills.

  • CISA vs. CISSP

    The CISSP (Certified Information Systems Security Professional) is a credential offered by (ISC)². While the CISA focuses on auditing information systems, the CISSP is geared toward implementing, monitoring and maintaining those systems.

    While some of the content covered by both exams overlaps, the jobs they prepare you for are quite different. The CISSP is ideal for careers in information security, and CISA is better suited for IT auditing. In terms of salary and earning potential, both certifications are roughly equivalent. According to (ISC)² salary data, CISA holders can expect to earn between $53,000–$122,000; CISSPs typically earn between $74,000–120,000 annually

  • CISA vs. CASP+

    CASP+ is an advanced-level certification offered by CompTIA. Although the exam will test you on knowledge related to compliance, governance and risk, the certification as a whole falls more in line with security engineering and architecture than CISA, which focuses on IT auditing.

  • CISA vs. CEH

    The CEH (Certified Ethical Hacker) by EC-Council is one of the most popular certifications for entry-level cybersecurity professionals. The credential validates that you can “think like a hacker” and use the tools a malicious attacker would use during an attack. Many CEHs pursue careers as penetration testers, malware analysts, and security analysts.

    It can be useful for understanding how attackers gain access to systems with improper controls, but the CEH is not focused on auditing like the CISA certification is.
