Curation Review

  • ✔ Pros: Strong 39 Gbps firewall and 36 Gbps IPsec VPN throughput in a 1U chassis; 5 million concurrent sessions and 4,000 IPsec tunnels suit mid-size enterprise edge; 1+1 redundant power supplies; MACsec support on all data ports; mix of RJ-45, SFP+, SFP28 and QSFP28 ports for flexible uplinks; well-regarded Junos CLI and SRX platform feature set
  • ✘ Cons: High acquisition cost compared with many competitors, especially once support and security subscriptions are bundled; New Sessions/sec figure is not published in Juniper's spec sheet; Threat Prevention throughput drops sharply versus firewall throughput when IPS/AppSecure are enabled; Juniper's IPS and GUI have drawn mixed user feedback; SSL-decryption capacity is limited relative to the headline firewall figures; end-of-life and stock availability of this model are uncertain on the secondary market
  • Est. Price: $51,750 - $137,354
