HackerWatch Test Your Firewall - Our server is ready to send traffic to your computer. You may select either of two methods. If you would like to simply generate some event traffic on your computer to test the event notification dialog and see some events in the log choose the simple probe.

broadband Security Port Scan - A modern port scan tool is used (nmap) and this attempts to identify the machine signature, and any vulnerable services running on it. If NETBIOS ports are open (indicating it is a Windows machine), then we attempt to talk to your netbios to see if there are any shares or printers visible, and to query your machine name and domain name.
BufferZone - Security Test - This test simulates an internet download similar to what any users may perform and will attempt to prove that none of your security systems will alert or identify our intrusion attempt. As you run the .exe file it will launch your calculator and scan your documents' names. We will then place your document names on our server and provide you with a link so that you can see what files we accessed.
Der Keiler: Free Online-Portscanner - This Online-Portscanner uses the open-source utility nmap to scan your IP and detect open ports. As the result of the scan, you will get raw nmap output, without any explaination. So if you use this tool, you should know what ports are and how to interpret the output.
Nmap Online - Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and both console and graphical versions are available.
SafeCenter | Online Anti-Hacker Scan - Anti-Hacker System, since it started in August 2002, has run over 32,000 scans on individual machines. Only 3% of those machines received a perfect score. 97% of them had one or more possible weaknesses, some had multiple weaknesses, These included unneeded network services, public machine names or usernames, guest accounts, routers with weak configuration protection, printers visible for anyone to use and more... Are you still sure?
Port Scan Alken.nl - This server will attempt to open several ports on your computer. If your firewall is configured to block a port, and it is operating correctly, you will see Secure and an event will be logged on your firewall. A Closed port indicates that the port is reachable but there is no program currently accepting connections there. If the port is indicated as Open there is an application or service on your computer actively accepting connections.The time to check each port will range from less than a second up to 20 seconds. Ports which are Secure will take the most time.
PC Flank: Exploits Test - This test will detect how vulnerable your computer is to exploits attacks. This test can be also used to test firewalls and routers for stability and reactions to unexpected packets. Most of the exploits are in fact denial-of-service attacks.
CheckIt Firewall Test - These scans test your systems vulnerability by scanning for common security holes in your operating system.
