Why & Which Juniper Enterprise Firewall to Buy in 2022?


Firewalls are network security devices that monitor outgoing and incoming network traffic and block or allow data packets based on a set of security instructions. The main purpose of Next-Generation Firewalls is to create a barrier between oncoming traffic and your internal network to block hackers and viruses.

Based on pre-established rules, Juniper Firewall wisely analyzes incoming traffic and filters traffic coming from suspicious or unsecured sources to avoid attacks. Firewalls keep an eye on traffic at a system’s entry point, known as ports, where info is swapped with external devices.

Types of Firewalls

  • SMLI (Stateful Multilayer Inspection) Firewalls:It filters packets at the network, application layers, and transport, comparing them with known trusted packets.
  • NAT (Network Address Translation) Firewalls: It allows several gadgets with independent network addresses to join the net with the help of a single IP address. At the same time, it keeps an individual’s IP address hidden.
  • NGFW (Next-Generation Firewalls): It combines traditional firewall tech with extra functionality, like intrusion prevention systems, encrypted traffic inspection, anti-virus, and more.
