Fantastic extension. Highly recommended and lightweight for your browser.
I have had this loaded on my computer for quite some time now and am completely satisfied with the performance on a daily basis and in unusual circumstances. I would and have recommended this security service since I found out about it and will continue to into the future. Thank you for protecting my computer and all the information and activity within it.
Great product as I've tried using other anti-phishing products. This one is by far the best I've found, so much so I've also installed it on other family computers.. It effectively identifies phishing links and alerts promptly if there's an abnormality. 10/10 recommend!

people recommend it and say how much it's helped them avoid phishing and those sneaky Zero-Day attacks. Plus, it's really easy to use, which is a huge plus in my book. The folks who made this thing seriously know their stuff, and I would totally recommend it to anyone who wants to feel secure when they're browsing the web.
