CASP+ gives 25 CEUs for Cloud+ but none for Linux+. Both CySA+ and PenTest+ give 33 CEUs for Cloud+ but none for Linux+. Cloud+ fully renews Liinux+. So technically, if you pass CySA+ (33 CEUs) and PenTest+ (33 CEUs), you have 66 CEUs for Cloud+, which would then renew your Linux+. CASP+ would renew the entire stack.
Linux+ and Cloud+ don't give CEUs for CASP+ because CEUs renew down not up.
Thank you so much for taking the time to find this! I already hold the trifecta (A+, Network+, Security+), along with Pentest+, CySA+, and CASP+. I recently passed Linux+, and I plan to earn Cloud+ around Christmas, which will automatically renew Linux+. For the Cloud+ CEUs, I’m thinking of using CertMaster materials from CySA+ and Pentest+. Each offers 25 CEUs, so with both, I can meet the full 50 CEU requirement for Cloud+ and simultaneously renew Linux+. Fortunately, I have access to these resources through my academic partnership. For both CySA+ and Pentest+, I took the exams when I was about 90% through the courses, so once I earn Cloud+, I can complete the CertMaster courses and use them for the necessary CEUs.
I believe CompTIA should consider allowing CEUs earned from any certification to count toward the renewal of any other certification, including CASP+. Certifications often encompass related knowledge, and CASP+—while an advanced security certification—is still for practitioners. If you're CASP+ certified but not proficient in Linux, it won't reflect well on your expertise. Acquiring Linux+ knowledge, for example, would significantly enhance your abilities as a CASP+ professional. In my experience, I’ve worked with CISSP-certified individuals who couldn't perform basic tasks, such as configuring an IP address. While I understand CISSP is meant for managerial roles rather than hands-on practitioners, there’s a gap between theory and practical skills.
ISACA has a compelling model in this regard: any certification renews any certification. At my job, they’re encouraging me to pursue both CISM and CRISC with employer sponsorship. When I spoke with an ISACA representative today, they explained that certification order doesn’t matter. Whether it's CISA renewing CISM or vice versa, any cert renews another. They also offer CEUs for a wide range of topics; even a certificate in IoT Fundamentals earns you CEUs toward CISA, CRISC, CISM, etc. Their philosophy is that knowledge is knowledge, and I agree. CompTIA’s CEU and renewal model could benefit from similar flexibility. Improving it would serve everyone in the community, fostering broader skill development across certifications.
