Frequently asked

When is the Juniper SRX4100-AC end of life?
Juniper's published notice sets End-of-Sale for the SRX4100-AC at Apr 15, 2026. The published end-of-support date is Apr 15, 2031, after which vendor support ends. Check the milestones on this page and plan the refresh ahead of the support cutoff.
What replaces the Juniper SRX4100-AC?
Juniper has not named a one-for-one replacement in the notice this page is built from. Uniqcli can recommend and quote the current equivalent for the SRX4100-AC, with TAA country-of-origin screening on request.
Can I still buy or get support for the SRX4100-AC?
New units are no longer sold by Juniper after the End-of-Sale date; remaining channel stock and refurbished units are the only sources. Vendor support continues until Apr 15, 2031 under an active support contract. For a fleet still running this hardware, the practical next step is a refresh plan — request a quote and we will price the current replacement.
