Key differences between CISM vs CISSP 

While CISM and CISSP are certifications awarded in cybersecurity, they have several differences. The differences aren't just about the professional body but also about the different domains. 

Let’s take a detailed look at the differences between CISM vs CISSP. 

Key differences between CISM vs CISSP

Work experience required 

Both CISM and CISSP are targeted at professionals who have some work experience. Naturally, to qualify for the certification, both require you to have a certain amount of practical work experience.   

To become CISM certified it is required to have at least five years of experience in information security in at least three domains. To qualify for the certification, you must have passed the CISM exam within five years from the date of application.   

CISSP requires you to have a minimum of five years of experience in two or more of the eight domains, according to the Common Body Knowledge (CBK). However, you get a one-year experience waiver with a four-year college degree or a regional equivalent. You also get the waiver if you have approved credentials from the (ISC)² approved list.   

Part-time job experience and paid and unpaid internships are also counted in the work experience, although you must satisfy some conditions regarding the number of hours worked. For full-time work experience, you must have worked 45 hours per week for four weeks to qualify it as one month of experience. For part-time work experience, the hours must be between 20 and 34.   

a) 1040 hours of part-time = 6 months of full-time experience  

b) 2080 hours of part-time = 12 months of full-time experience

Job Roles and titles

Popular job roles for CISM vs CISSP

Even though both certifications are cybersecurity certifications, the job roles might differ because of the emphasis. CISM focuses on the managerial aspect of information security, while CISSP focuses on technical and managerial aspects.  

To understand the difference better, it is essential to point out that CISSP requires more technical knowledge and skills than CISM. While it also focuses on some technical aspects, it is primarily geared towards professionals more apt with a manager role instead of just being good at technological know-how.  

If you love working in the technical domain, CISSP is a better choice, while if you like working in managerial positions, CISM is better suited.

Salary and earning potential 

There is no doubt that the salary increases irrespective of the certification. However, earning potential can change based on your chosen roles and responsibilities. Many variables are involved to point out an exact number for the salary, but it is possible to give a rough estimate of average salaries.  

The salaries for CISSP and CISM also depend on the certification's demand. Even though getting these certifications can increase your salary, depending on your employer, the hike in salary won't be much as you expect. The real potential of these certifications lies in the opportunities and the job roles open for you. Getting certified gives you access to better job roles that fetch better salaries, and employers are more likely to hire you, giving you a better offer than non-certified individuals. Is CISSP worth it? Absolutely. Achieving CISSP certification not only enhances your skill set and knowledge in the field of information security but also significantly elevates your marketability and career prospects.

Certification maintenance cost 

Getting the certification is not enough, you need to maintain your certification as well. To maintain your CISM certification, you need to earn 20 CPE credits per year, 120 CPEs over three years and commit to a Code of Professional Ethics. On the other hand, to maintain your CISSP certification, you need to earn 120 CPEs per three years and pay an annual membership fee of £68 for non-members and £36 for members. 

Training required 

Getting either the CISM or CISSP certification is not easy, and both need extensive support, CISSP Study Guide and preparation. The domains are less than CISSP's and majorly consist of managerial aspects. This makes preparing for CISM slightly easier but it still needs appropriate training.  

Choosing a training institute, boot camp, or virtual classroom training can be a great way to train yourself for the CISM or CISSP certification. For CISSP, there is a CBK that contains all the topics you need to learn and prepare for. Having the ISP CBK can help you immensely in understanding the topics given. CISSP also has more topics to cover as it has eight domains.The CISSP Certification stands out for its comprehensive coverage of information security, with eight domains collectively known as CISSP domains. If you wish, you can prepare on your own with appropriate training materials, but it is better to take help from a training institute that can help you prepare better for the exam. 

Which one is better: CISSP or CISM? 

These two are not opposing certifications, but they can complement each other. If you are certified in CISM, you can also get CISSP certification. The CISM certification can waive off two years of work experience needed for the CISSP certification.  

Before choosing the certification, take some time to understand your interest. If you are more inclined towards managerial positions, CISM will be a better choice, whereas if you are interested in technical aspects of information security, you will benefit more from the CISSP certification.
