TECHNOLOGY DESCRIPTION
Working from home for many has become the “new normal” during the COVID-19 pandemic. Threat actors are shifting tactics to target these remote employees who may not benefit from corporate security. This makes the protection offered by web browsers more important than ever.
Email, instant messages, SMS messages and links on social networking sites are used by criminals to lure victims to download and install malware disguised as legitimate software (a.k.a. socially engineered malware). Once the malware is installed, victims are subjected to identity theft, bank account compromise, and other devastating consequences. Those same techniques are also used for phishing attacks, where victims are lured to websites impersonating banking, social media, charity, payroll, and other legitimate websites; victims are then tricked into providing passwords, credit card and bank account numbers, and other private information. In addition, landing pages (URLs) from phishing websites are another way attackers exploit victims’ computers and silently install malicious software.
The ability to warn potential victims that they are about to stray onto a malicious website puts web browsers in a unique position to combat phishing, malware, and other criminal attacks. To protect against malware and phishing attacks, browsers use cloud-based reputation systems that scour the Internet for malicious websites and then categorize content accordingly, either by adding it to blocklists or whitelists, or by assigning it a score.

WHAT WE TESTED
NSS Labs conducted 129,068 discrete tests of malware protection (32,267 per web browser) over a period of 34 days, and 189,096 discrete tests of phishing protecion (47,274 per web browser) over 18 days. The reports include measurements of protection against fresh new attacks, consistency of protection over time, and how effective the browser protection was overall.
The Comparative Test Reports provide detailed results including block rates for each product and data recording consistency of protection over time. As a service to the community, NSS Labs is providing these reports for free.

PRODUCTS EVALUATED:
  • Google Chrome: Version 81.0.4044.113 – 81.0.4044.138
  • Microsoft Edge: Version 83.0.478.10 – 84.0.516.1
  • Mozilla Firefox: Version 75.0 – 76.0.1

You go into the same trap like me :D

The real test's are the other two ones.
The one with login is a old PDF from 2018 without any browser results

I googled on NSS lsbs and what striked me that Microsoft products always came out best (even IE). This is a real downer, because I use Edge based on features it has (e.g. code integrity guard for renderer process by default, the de-elevate flag on launch and smartscreen).

I loved to have my thoughts on Edge confirmed by a real independant testing lab. Pity NSS labs does not tick those boxes.

Edge should be safer tban Chrome, but these lab results are not the confirmation I was hoping for.
