Network & Security

Eliminate Annoying Ads and Improve Page Download Times

Ad Blocker enables administrators to block web ads at the gateway by transparently removing them from web pages. Benefits include:

• Easier to read web pages without distracting ads
• Improved page download times
• Reduced traffic on the network

Key Features:

• Create custom rules and exceptions
• Automatic updates
• Event log details all blocked ads

Network Visibility & Monitoring

Reports provide administrators the visibility and data necessary to investigate security incidents and enforce acceptable network usage policies.

• Monitor behavior at the user, client and incident level

• Understand traffic flows and network usage patterns

Share reports in PDF or HTML formats

Visibility is the first step in controlling your network, identifying misuse, and enforcing your network usage policy. Reports provide this visibility and is also a great tool for troubleshooting.

You’ll get daily, weekly and monthly reports about the activity in your network and each firewall software application. How many viruses and spam were blocked? Which phish were caught? What Websites were visited?

Reports can be delivered via email or viewed on the Web.

Key Features:

• Open Source & Free under the GNU General Public License (GPL)
• Summary, detail, and per user reports
• Automated email report delivery
• Report archive

Your First Line of Defense

Firewalls draw the line which separates internal and external networks.  system’s Firewall filters traffic based on IP address, protocol and ports that allow administrators to:

• Designate which systems and services (http, ftp, etc.) are publicly available
• Create a DMZ and perform NAT (with Router)
• Run as a transparent bridge to complement existing hardware

The Firewall is the most basic security element to hide your network from the outside and control all external access points (also known as ports). It lets you block unwanted activity and protect your network.

You can build a list of rules that meets your unique needs—control traffic by protocol, source address or port, destination address or port, and set default actions.

Firewall evaluates traffic traveling across your network by applying your rules until a block/pass verdict is reached or a default action is taken.

Key Features:

• Open source & Free under the GNU General Public License (GPL)
• Easily blocks sessions based on simple rules
• Rules can be based on a variety of attributes

Technical Specifications:

Firewall can both monitor and block traffic sessions based on simple, yet flexible rules. The Firewall enables you to control traffic by:

• Protocol
• Source address or port
• Destination address or port

You can build your own list of rules, and dictate how the Firewall must respond.

What It Does

Provides traditional firewall functionality

How It Does It

Uses system proprietary technology for rules-based logging or blocking of network traffic

Controls

• Default action can be globally set to "block" or "pass"
• Custom logging, blocking or passing rules can be created by:
  • protocol
  • direction
  • source address
  • destination address
  • source port
  • destination port
• Rule matching order can be customized

Block Port Hopping Applications

Protocol Control lets administrators take back control of their networks from disruptive port-hopping applications like peer-to-peer applications or online games.  Signature based layer 7 filtering makes it easy for administrators to:

• Conserve bandwidth by blocking applications like peer-to-peer that open multiple TCP ports
• Improve productivity by blocking IM & online games that evade firewall rules
• Write custom signatures for any protocol

Protocol control covers a broad set of applications, such as Instant Messaging, Peer to Peer activity, online games and streaming media, that can clog your network, reduce productivity, and infect computers with spyware, malware, and viruses.

These applications are extremely aggressive and will sneak out on ports used for other vital network traffic such as web and email, making it nearly impossible to control them with firewall rules.

Protocol Control takes a different approach to log and/or block these applications using their signatures. This allows you to lock down the unwanted activity.

Key Features:

• Open source & Free under the GNU General Public License
• Protocol control lets you select the protocol signatures to log or block
• Custom rules can be added for any unsupported protocols
• Time based policies let you decide when and if these applications are permitted
• Reporting lets you see which protocols are active on your network and who is using them
