The ZyXEL SBG3300-N series applies ACL rules, Stateful Packet Inspection (SPI), Denial of Service (DoS) and DDoS features for first-line defense against hackers, network intruders and other harmful threats. A configurable DMZ provides more flexible accessibility while preventing external attacks on confidential databases.
The ZyXEL SBG3300-N series includes multiple WAN interfaces for DSL, Ethernet and USB 3G/4G adapters to establish WAN backups or load balancing. The WAN backup provides contingency in case the primary line or ISP suffers temporary outage. When the primary line of normal services is restored, all traffic resumes normal activity. This function enables highly reliable connectivity and flexibility in multiple applications.
The ZyXEL SBG3300-N series offers a two-level login mechanism to differentiate user segments. The ISP can also define the policies for the limited accounts to easily manage them with the integrated profile database.
