ShieldsUP Tests Your Firewall For Vulnerabilities

The best way to determine if your computer's (or router's) firewall is working and optimised is to effectively try to penetrate it. Browser-based utility ShieldsUP! tests your firewall for vulnerabilities and kinks in your computer's defence.

After you give ShieldsUP! permission to run tests on your computer and choose a test type, it looks for weaknesses and openings that hackers and intruders can use to attack your machine. You can test in five different categories: file sharing, common ports, all service ports, messenger spam and browser headers. When a test completes, ShieldsUP! will displays the results and offer suggestions for how you can improve your security, with detailed explanations. It's a good tool for evaluating your computer's security and determining whether you need to amp up your computer's defences.

    Pity that they off line !!!!!

    ShieldsUP! has been overloaded by LifeHacker!!

    We're sorry to have to pull the service down, but the MASSIVE FLOOD of users sent to us by the mention on Lifehacker (which we TOTALLY appreciate!), coupled with the length of time (a few minutes) to test all ports, can possibly be serviced. Once the massive wave of usage has passed we'll be able to put ShieldsUP! back online and we sincerely hope you'll give it a try. But for the time being we're just too swamped! Sorry!!

    I've heard of the Slashdot effect, but this is the first time I've seen the Lifehacker effect.

    GRC's 'ShieldsUp!' test is literally 7 or 8 years old by now..... Is this really news? :\

    Also, the test is down at the moment due to the traffic generated by this.

    oh oh ... Looks like we killed it: http://cl.ly/3Zq

    Um, you broke it guys! They have taken the service down (temporarily) due to the flood of traffic generated by your article.

    Good to know that people read your articles! :)

    The power of LifeHacker. You broke it!! :)

    You broke it.... The site is still down from yesterday :P

    the site is displaying a page that says:
    "We are SO SORRY to have to temporarily take the service offline — which has been up for many years and has performed more than 83 million port security scans for people.

    But we cannot possibly service the MASSIVE FLOOD of users sent to us by its April 7th, 3:00pm mention on Lifehacker (which we TOTALLY appreciate by the way!) due to the length of time (about a minute or so) required to test each visitor's ports.

    Once the massive wave of usage has passed, we'll be able to put ShieldsUP! back online and we sincerely hope you'll come back and give it a try! But for the time being we are just too swamped! Sorry!!"

    looks like ill have to wait till the site is back up and running at full steam...

    Haha, "ShieldsUP has been overloaded by lifehacker"

    It appears that the GRC website is no longer running any tests due to it getting slashdotted (lifehackered?).

    In a post on their site:

    ...ha ha lifehacker strikes again. Service unavailable due to load.

    I'd like to mention that ShieldsUP is currently down due to the traffic they recieved after this post. Great work from the Lifehacker guys :)
