Congestion Management

INS does not implement any congestion management techniques. INS operates our network to accommodate the necessary traffic requirements. In the event of congestion, all traffic is classified as best effort.

Content, Applications, Service and Device Providers

As a full service Internet Service Provider, INS delivers a full suite of Internet-based applications. These include:

  • Voice over Internet Protocol (VoIP)
  • Email
  • Web Hosting

INS does not discriminate any customer traffic. INS utilizes the network management techniques that are equal and standard across all user applications. We do not modify our network to make our directly served applications perform better than applications a user would access over the general Internet. For example, INS does not manipulate our network to perform better for customers accessing netINS email servers versus netINS customers accessing Google's gmail.

The network management practices employed by INS do not differ between our directly offered applications to those general applications offered over the Internet.

Security Measures

In the event of Denial of Service (DoS), Distributed Denial of Service (DDoS) attack,spoofing or other malicious traffic, INS will implement inbound and outbound filtering on specific hosts. These actions will be performed to ensure reliability and availability of the INS Network. These actions will not be utilized for normal Internet applications and traffic.

Each level looks for and removes specific threats such as content analysis, virus detection, sender profiling.
Outbound - Outbound traffic is inspected to identify computers that have been infected and converted to a "zombie" or botnet client. Zero-Minute-Defense - Employs real-time knowledge gathered from a worldwide sensor network and uses it to create new detection and protection rules, which are then sent as updates on a continuous basis.
