Frequently asked
How much does Fortinet NSE 4 cost?
The NSE 4 exam costs $200 USD at Pearson VUE test centers or online via OnVUE. Unlike NSE 7 and the Industry Certification exams, NSE 4-6 pricing does not change on November 2, 2026.
Do I need NSE 1-3 before NSE 4?
No. NSE 4 has no mandatory prerequisites; Fortinet only recommends taking the associated course to prepare. The free NSE 1-3 courses are a helpful on-ramp but are not required.
What happened to the Fortinet FCP certification?
Fortinet retired the FCP credential on July 15, 2026 and restored the numbered NSE program. FCP maps to NSE 4 for holders who passed the FortiOS exam, plus NSE 5 or NSE 6 depending on which second exam they passed. Existing holders keep their certification until it expires.
Is NSE 4 required for higher Fortinet certifications?
Yes. An active NSE 4 is the prerequisite for every NSE 5 and NSE 6 track certification, and the chain continues through NSE 7 to NSE 8 and the Industry Certifications.
