Firewall Throughput: Up to 400 Gbps (1518B and IMIX, per Juniper HCT hardware specs). Older datasheet figures differ and should be checked against the current Junos release.
Threat Prevention Throughput: Not confirmed in verified sources. An older datasheet cites roughly 80-90 Gbps with application security enabled; treat as unverified.
Form Factor: 1U fixed chassis (1.72 in / 4.37 cm height); 2x hot-swappable PSUs in 1+1 redundancy; front-to-back airflow; AC max 800 W, AC average 650 W; DC variant also available
PoE: Not applicable (security gateway, no PoE)
Curation Review
✔ Pros:Up to 400 Gbps rated firewall throughput in a 1U chassis; 4x QSFP28 ports allow 40/100GbE uplinks alongside 8x 10GbE; Dedicated SFP+ chassis cluster ports support active/passive HA; Very high concurrent session capacity (about 60M) and 7,500 IPsec tunnels; Redundant hot-swappable 1+1 power supplies with front-to-back airflow; Junos-based SRX platform with full security service options
✘ Cons:New units list at roughly $117,000-$211,000 before subscriptions, far above most SMB and mid-market needs; Threat prevention throughput is not clearly published, and the 400 Gbps figure is an up-to rating under Juniper's test conditions; Published new-connections-per-second and older AppSecure/IPsec figures conflict across sources; Advanced security subscriptions add substantial cost (one listing shows about $255,000 for a 7-year Advanced bundle); No PoE or wireless capability, so it serves only as a security gateway; Juniper's official spec pages redirected to HPE during research, so confirm current support and lifecycle status before purchase
