VisNetic Firewall is a packet-filtering software firewall built to protect Windows-based Servers,
telecommuters / mobile users, and LAN workstations not currently protected by a firewall. VisNetic
Firewall is more secure than application-based personal firewalls, yet less expensive than high-end software firewalls.
Organizations running software and/or hardware Internet sharing solutions
are as concerned about internal threats as they are about external threats.
There is currently not a hardware firewall solution that protects companies
against these threats and existing software firewall solutions are priced
outside of the small to medium business.
The current version of VisNetic Firewall is 2.3.
- NT 4 Server
- Win2000 Server
- Win2000 Advanced Server
- Win2003 Server

Key Features of VisNetic Firewall :
- Stateful Packet Inspection
VisNetic Firewall falls into a class of firewalls called Stateful Inspection Firewalls.
Stateful inspection firewalls determine whether packets can get through the firewall based
on the protocol, port, and source and destination addresses. For every request that is
allowed by this strategy, stateful inspection firewalls open up a limited time window to
allow response packets, but ONLY from the same host.
- Port Scan Detection
VisNetic Firewall detects the seven most common forms of port scans, alerting you with a log
entry and optionally automatically banning the IP address of the scanner, ensuring that they
are "cut off" before they can discover any useful information about your system.
- SYN Flood Detection
A SYN Flood is a common type of denial of service (DoS) attack used against servers. When
launching a SYN Flood, an attacker bombards you with so many connection requests that your
computer is unable to accept legitimate connections, effectively shutting down your web, email,
FTP or VPN server. VisNetic Firewall employs SYN cookies to protect you from SYN Flood attacks.
- Remote Administration
Using the remote administration component of the Server version of VisNetic Firewall, you can now
remotely administer any VisNetic Firewall using an encrypted communications link. You can also reboot
or shut down the remote system using the remote admin controls. In addition to remotely administering
other Server or Workstation firewalls, you can use the stand-alone Remote Administration Tool to
remotely connect to your own Server firewall.
- IP Address Ban List
VisNetic Firewall lets you block IP addresses or ranges of addresses to prevent unwanted connection attempts.
This can be particularly effective in stopping repeated requests from a hacker who is trying a large
number of hacks, looking for one that works.
- HTTP Filtering
Using VisNetic Firewall HTTP Filtering, you can prevent intrusion attempts targeted at your web server
by screening requests and automatically banning the offender抯 IP address, preventing further access.
- MAC Address Filtering
VisNetic Firewall now has the ability to filter traffic based on MAC addresses. Because a MAC address is
specific to one individual network interface, this feature is particularly useful if you want to allow or
block traffic from a particular computer whose IP address may change.
