NetGu@rd＋
(NetGuard Plus)
We protect customer networks and services from large-scale DoS/DDoS attacks.
NetGu@rd+ is an optional service designed for customers using BroadBand Tower's network service/c9 Flex service.
By detecting and reducing DoS/DDoS attacks at a higher network level than the Firewall/IPS installed in the customer network, NetGu@rd+ will protect customer servers, network devices, and Internet connection.

Features
NetGu@ard+ is a service that filters out malicious traffic before it enters a customer's network by installing an anti-DDoS system in BroadBand Tower's high-capacity backbone network.
Protection policy fit for your network
We will learn and analyze traffic to the target network prior to the start of service.
A protection policy made based on that analysis will be created for the customer network and will allow for an accurate and high-quality filtering out of unwanted traffic.

Selective blocking of dangerous traffic
During normal times, the network traffic analyzer will be monitoring traffic. When an abnormality is detected, all traffic towards customer servers/network will be pulled to the anti-DDoS system. The anti-DDoS system will assess and forward the traffic back to customer servers/network after cleaning of the unwanted traffic.
Abundant Report Features
Customers will be able to check reports on how many DoS/DDoS attacks were detected and reduced on a dedicated portal.
Extensive Service Menu
Customers can start small, targeting even a single IP address for protection. We also offer a spot service for customers who only need DDoS protection for a limited time. Settings changes are available for all service options, allowing you to add more targets for protection as needed.
