About

The Qualys Certified Specialist (QCS) program is a vendor-specific certification suite designed to validate expertise in deploying, configuring, and operating Qualys cloud platform modules. Unlike platform-agnostic security certs (e.g., CISSP, Security+), QCS credentials target hands-on practitioners and solution specialists working with Qualys VMDR, Patch Management, PCI Compliance Scanning, Web Application Scanning (WAS), Cloud Agents, and TruRisk modules. The program offers free official training and exams through the Qualys Learning Center, with lifetime validity upon passing. Multiple specialization tracks allow candidates to certify in specific functional areas relevant to their role.
