The webpage at https://www.mcafee.com/consumer/ja-jp/landing-page/direct/sem/mtp-family/desktop/sem-cp.html might be temporarily down or it may have moved permanently to a new web address.
This is beyond a disaster. Not only is the page inaccessible, but even the Open Graph data is empty. Such a massive oversight is unfathomable for a company of this stature. Without any available information or visuals, it's impossible to assess what the page is about, let alone critique its design or messaging. Getting this fixed should be priority number one; until the page is up and running, it's impossible to even begin talking about user engagement or conversion optimization.
