Deployment Methods

1- GRE Tunnel Solutions
Nexusguard Tunnel solution uses GRE to create a tunnel or virtual transport system to connect Nexusguard with client infrastructure. BGP is then used inside the tunnel to exchange routing information. Tunnel solution is flexible and transparent, preventing any modification of client data using Network Address Translation or other methods. Nexusguard Tunnel solution is stable and reduces the risk of a client’s real IP being attacked.

2- Direct Circuit
Created for discerning customers who demand the highest level of protection, Direct Circuit establishes a direct physical connection between Nexusguard and the client. Although more costly than the previous option, clients can enjoy dedicated true out-of-band connection for optimal security and reliability.

1. Professional Service team consultation required for purchasing InfraProtect with Direct Circuit deployment mode.
2. Private ASN can also be used to establish BGP peering in DC mode.
3. Private IPv4 addresses can also be used to setup BGP peering in DC mode.
4. Customers who do not have ISP lines that support IP transit can acquire customized solutions from Nexusguard.

Nexusguard Infrastructure Protection
Nexusguard offers 2 flexible modes - InfraProtect Auto and InfraProtect Control - to meet your business needs.

InfraProtect Control


InfraProtect Auto


Secure your business from collateral damage caused by DDoS
DDoS attacks are a critical concern for data centers and other service providers. Uninterrupted availability of Internet access is often a business-critical requirement for its customers and yet, many of these customers on the same infrastructure run businesses inherently vulnerable to DDoS attacks. During these DDoS attacks, not only the targets are made unavailable to their intended users, other non-targeted customers on the same infrastructure also suffer as collateral damage. Incidentally, the hosting/Internet service provider shoulders substantial bandwidth cost, suffer customer complaints and damage to its reputation. This can result in loss of customers, loss of revenue and even invite litigations.

Nexusguard’s InfraProtect is a fully managed null-route solution tailored for service providers that shoulders DDoS attacks so that non-targeted customers continue to enjoy uninterrupted connection.
