Web of Trust (WOT) – Crowdsourced web safety

Web of Trust (WOT) is a website reputation and review service that helps people make informed decisions about whether to trust a website or not. WOT is based on a unique crowdsourcing approach that collects ratings and reviews from a global community of millions of users who rate and comment on websites based on their personal experiences.

The community-powered approach enables WOT to protect you against threats that only the human eye can spot such as scams, unreliable web stores and questionable content. It complements traditional security solutions that protect computers against technical threats such as viruses and other harmful software. WOT is based on a patented system where user behavior is systematically analyzed and monitored to ensure the ratings are reliable, accurate and constantly updated. In addition, the ratings are validated with trusted third party information, such as blacklists of phishing sites.

WOT works in a very simple way - it shows website reputations as traffic lights next to search results when using Google, Yahoo!, Bing or any other search engine. They are also visible next to links in social networking sites like Facebook and Twitter and email like Gmail and Yahoo! Mail as well as other popular sites like Wikipedia. By clicking the traffic light icons you can find out more information about a website’s reputation and other users’ opinions. A green traffic light means users have rated the site as trusted and reliable, red warns about potential threats and yellow indicates that you need to be cautious when using a site.

For example, online shoppers who explore new sites may be concerned about which ones can be trusted in terms of quality of products and customer service. By using WOT they can check potential issues of unknown sites, read other peoples’ reviews and compare the reputation of different sites. We all want to explore the net safely and WOT helps you to do this with unknown and less popular sites.

WOT was founded by Sami Tolvanen and Timo Ala-Kleemola when they were post-graduate students at the Tampere University of Technology in 2006. They wanted to create a system where people could share their real-life experiences of different websites, so that other users could benefit and find sites they can trust.

Today, WOT is the world’s leading crowdsourced website reputation service with over 80 million downloads worldwide and collaborates with the world’s leading Internet companies such as Facebook and the Mail.Ru Group. WOT Services is headquartered in Helsinki, Finland and the CEO is Markus Suomi.

It only takes a few seconds to add WOT to your browser and rate a website to protect yourself and all other WOT users from online threats that anti-virus software can’t spot. Together we can make the Internet a safer place for everyone.
