Juniper SIRT (JSA) via NVD
Juniper's advisory portal (kb.juniper.net) is a login-walled Salesforce app, so VulniPulse ingests Juniper SIRT (JSA) advisories from NVD, filtered to Juniper's own CNA ([email protected]) — official, machine-readable data with the affected Junos releases in each description. Junos on SRX/MX/EX/QFX and Junos Space are the common targets.
