The best websites to check the security of a URL (without clicking the link)

23 mayo, 2021

It seems that surfing the Internet is less and less safe: sometimes it seems that every click we make on an unknown URL (from some apparent email phishing campaign or, worse, from the huge range of link shorteners available today in the guide) is like stepping into a field of mines.

It certainly helps to have antimalware applications that protect the computer in real time and block the opening of certain URLs. But And could we move forward without taking missteps, knowing with some certainty that we will end up with a trustworthy web address? That’s what URL checkers were invented for. We show you a selection of the most useful:

Ransomware: what it is, how it infects and how to protect yourself

Norton Safe Web

Norton is one of the big names in cybersecurity, so we can trust your threat database will allow you to rule out many of the potential threats that we could find in our browsing sessions. The advantage is that the use of Norton Safe Web is completely free.

After entering the URL of our interest, It will tell us if it is safe, specifying three indicators– Malware threats, identity threats, and ‘nuisance factors’, a term that encompasses bad practices by website owners, such as trying to install unwanted software (even if it is not malware). In some cases we will also find ratings and comments made by the user community.

URLVoid Website Reputation Checker

Urlvoid Some of the 35 blacklists consulted by the URLVoid service.

The URLVoid Website Reputation Checker is a tool whose use does not differ in any way from the previous one, although the information it offers the user about the URL does of our interest.

First of all, it provides us information about domain registration and server location, indicating if it appears in some of their 35 ‘blacklists’. Next, the evaluation of each of these lists is detailed, so that (if it were the case) we could know in which it appears; all of them are linked to cybersecurity companies and institutions (such as Avira, the CERT-GIB).

Google Transparency Report

Google’s Safe Browsing technology scan millions of URLs per day for potentially unsafe sites, which allows you to display warning notices in your search engine and in web browsers that use your technology. But his Google Transparency Report also allows us to use this technology on demand, indicating if the site is secure or not, and when was the last time that URL was verified.

It's 2020, but avoiding many phishing scams is still as simple as reading carefully

Sucuri Sitecheck

Sucuri does not live to protect the user against unscrupulous webmasters, but is a service aimed at protecting web pages against cyberattacks (code injection, DDoS, etc.), especially popular with WordPress-based site administrators.

But, in addition to that, they maintain a free online tool, Sucuri SiteCheck, which not only allows you to verify the security of a URL (checking it against 9 different blacklists), but also It tells us to which other URL it redirects (very useful when faced with link shorteners) and if the latter has an HTTPS version.

URLEX

URLEX (URL Expander) is an extraordinarily simple tool: it shows us a text box in which we can enter multiple shortened URLs at once, so you can show us which websites actually redirect. It also provides us with the option of downloading the results in the form of a .csv file.
