Yes, if your work lives on GCP. The $200 exam fee is one of the lowest in professional cloud security certifications. The credential signals genuine platform depth that CompTIA Security+ alone cannot. But PCSE is a platform-specific cert -- it carries limited market value in AWS-dominated or Azure-dominated environments. Choose your cloud security cert based on where your employers actually operate.
