Web Usage Monitoring and Blocking

NSG utilizes in-house developed software to bring you network-wide monitoring of your corporate network users' web browsing habits. Content filtering is accomplished using an advanced firewall, creating a complete package for management of your corporate network's Acceptable Use Policy.

Intrusion Detection

"Hack" attempts and even successful network security compromises from the Internet can be detected by an Intrusion Detection System (IDS). Network Services Group can install and configure a Linux-based IDS server on your network, giving you a looking glass into the state of your network security at any given time.

Vulnerability Assessment

NSG can examine your existing workstations and servers as they appear both on your LAN and present to the Internet itself, to determine if these machines are vulnerable to compromise. We use sophisticated vulnerability scanning software as well as the benefit of our years of expertise in this area to identify vulnerabilities and loopholes which need to be closed in your network.

Managed Firewalls

A Firewall is a system which limits network access between two or more networks. Normally, a Firewall is deployed between a trusted, protected private network and an untrusted public network. For example, the trusted network might be a corporate network, and the public network might be the Internet. A Firewall might grant or revoke access based on user Authentication, source and destination network addresses, network protocol, time of day, network service or any combination of these. These settings are normally controlled by the Network Administrator. Managed firewalls are firewalls that are setup, supported, and monitored by a qualified and trusted source usually outside of the organization.
