SUNNYVALE, Calif., April 25, 2023 –Juniper Networks (NYSE: JNPR), a leader in secure, AI-driven networks, today received “AAA” ratings for Routing & Access Control, SSL/TLS Functionality, Threat Prevention and Stability & Reliability in the Enterprise Network Firewall evaluation by, a nonprofit member organization that provides transparency and expert guidance on cybersecurity risks via research and objective product testing. Juniper also achieved the highest security effectiveness score of 99.94%. tested the Juniper Networks SRX4600 Series Firewall deployed as a campus next-generation firewall, a scenario widely used in mid-size to large enterprises globally. The SRX4600 achieved top scores across all five tested categories:

  • AAA in Threat Prevention: 99.94% exploit block rate with 100% resistance to evasions and 0 false positives
  • 7,572 Mbps overall rated performance
  • AAA in TLS/SSL Functionality: Supporting 100% of the tested cipher suites and encryption use cases across both TLS 1.2 and 1.3
  • AAA in Routing & Policy Enforcement

This test further validates Juniper’s Connected Security portfolio and commitment to delivering effective threat protection, performance and automation across a wide array of use cases, from Zero Trust data centers for public and private clouds to Next-Generation Firewall (NGFW) and Secure Access Service Edge (SASE). These results confirm Juniper’s continued leadership in security efficacy and performance over the last four years. 

Highest Security Effectiveness & Low TCO
The Juniper Networks SRX Series Firewalls offer full next-generation firewall capabilities, including application identification and security, industry-leading IPS, advanced threat prevention and secure connectivity for remote users. The results noted that the SRX4600 Firewall achieved the highest rating of “AAA” for Threat Protection. Juniper blocked 99.94% of tested exploits and 100% of evasions without a single false positive.

Given the sharp rise in application vulnerabilities and targeted exploits, a firewall that does not handle SSL/TLS effectively leaves traffic vulnerable to session intercepts, such as person-in-the-middle attacks. The SRX4600 received a “AAA” rating for SSL/TLS functionality, with noting that all tested cipher suites were supported for TLS versions 1.2 and 1.3. The SRX4600 also passed all additional encryption tests, including decryption validation and preventing insecure ciphers, including null and anonymous — or unsigned — ciphers.

“Juniper is a leader in Network Firewalls. Our SRX4600 not only scored a ‘AAA’ rating but also received the highest possible score in the test,” said Samantha Madrid, Group VP of Security Business & Strategy at Juniper Networks. “In light of economic constraints, customers tell us that 99.94% security effectiveness coupled with performance that lowers OpEx costs is more important than ever. We are incredibly proud to deliver our customers top-notch security while meeting their needs.”

“When organizations make new security investments, they need to know they are effective. Our unbiased, independent test results help them get past the marketing noise,” said Vikram Phatak, CEO of “Juniper Networks’ firewall protected the network against practically every threat we threw at them. Customers should know – it works.”
