The latest buzzwords in Firewall arena no doubt are NGFW and UTM. NGFW stands for Next Generation Firewall while the abbreviation of Unified Threat Management is UTM. Both of them do have certain extent of correlations. In this article, we like to discuss a bit on NGFW here and the UTM will be the next.
The NGFW, Gartner defined it a decade ago as “a deep-packet inspection firewall that move beyond port/protocol inspection and blocking to add application-level inspection, intrusion prevention, and bringing intelligence from outside the firewall”.
Its features include but not limited to:
a) blocking threats at the network edge (e.g. sandboxing and URL filtering); b) Geolocation (i.e. IP address and physical locations); c) Reverse proxy / web gateway; d) IDS/IPS (i.e. Intrusion Detection and Prevention System)
NGFW emerged to provide all the capabilities of a traditional firewall, and the additional capabilities of application control and integrated intrusion prevention.
They also provided more granular capabilities to identity user, location, and application.
Most importantly, NGFW can be a low-cost option for companies looking to improve their basic security because they can incorporate the work of antiviruses, firewalls, and other security applications into one solution.
