Best Free Internet Safety Check



In the past, I've relied on parental filters and anti-virus software. Well, now I've been forced to use these safety checks since I've found them to be very useful. I sure like checking on a website before I risk browsing it. Even though it doesn't replace any of my existing security measures - except perhaps the parental filter - this additional layer of security is really useful.

Check out this review of internet safety check which covers two sections: Installed Software and Online Services. I've rated these products by looking at six criteria:

  • Ratings that are reliable with more information close at hand.
  • Scanning that doesn't slow me down too much.
  • Warning about and blocking of risky sites.
  • Searching options including icons that link to the full rating.
  • Compatibility and integration with the web browsers and operating systems.
  • Detecting web pages and sites that have active or reported threats

More About Internet Safety Check

Rating and scanning

The two types of safety check for a web address or URL are rating and scanning. Scan the website for threats (right now when I need it) or rate the reputation of the website using other sources of information: what people think of it, whether it has been associated with any dishonest or illegal activity, and what other security databases have on record which can include the results of your past scans.

Safety checks are easy to install and use

These products are easy to install and use because there are few options to configure. Most run in the background while you browse the Web and only pop-up when they identify a problem. The products mainly install as a browser add-on for each supported web browser. Just be warned that browsing can be noticeably slower and will usually crawl on a dial-up connection or if you run several products at the same time. Often there is a single button added to the toolbar (as with WOT) and sometimes an entire new toolbar (as with LinkExtend).

Online safety checks are an alternative

If you don't want to install more software on your computer then you can use an online service. You manually check websites by typing or copying the web address into the online check website. They are less convenient but are an effective option particularly to get a second opinion. I've included the best in this article but the remainder can be found in the full list of products reviewed.

Web browsers have built-in safety checks

Many of you will realize that you are already using an internet safety rating as a feature of your web browser. For example, Microsoft calls it SmartFilter for Internet Explorer, and Firefox has options to block "reported attack sites" and "reported web forgeries".  Apart from Internet Explorer, the main web browsers source their safety data from other vendors: Firefox, Chrome and Safari use data from Google Safe Browsing; and Opera relies on AVG. I tested them in the same way as the other products and services. In terms of detecting bad websites they were in the middle third of the products I reviewed.

Color-coded results

WOT rating symbolsTypically, the products present their results with color-coded symbols as shown in the image from Web of Trust (WOT). The WOT scorecard uses rating symbols that have five levels of color from dark green for trustworthy, yellow for concern, and orange to red for dangerous. Grey is used for unrated sites. Most programs work in a similar way, placing an icon beside web links so that moving the mouse over the icon will display the rating; and clicking on the icon or pop-up displays the full scorecard. Online meta-scanners, which use the results of many different scans, are the main exception. Although many use similar colors their rating is usually the fraction of the tests for problems found e.g. 9 of 15, 9/15.
