What comes after passing
Cybersecurity Defense Engineer is valid for 3 years. All Splunk certifications run a three year life cycle from the date of the highest certification exam passed. Splunk stopped renewing certifications through coursework on 1 March 2026, so renewal now means either retaking the same exam in the final year of the window or earning a higher level certification in the same track. Splunk says a certification you let lapse is marked inactive, and that you then restart the programme at the Splunk Core Certified Power User level.
