Great question! There are a number of answers depending upon the type of site and how the site was accessed. Let's cover each in turn in the following sections.
Ads
All lookups of known ad sites will be redirected to the LuJam sensor, which will return a single blank dot or pixel. This means the ads shouldn't appear anywhere on your screen, although sometimes the hosting site may well display them in a fixed-size regions, which will just appear empty. Some sites are quite clever and will detect that LuJam is blocking ads -- it's really up to you if you want to proceed and use these sites. If you need help configuring the adb blocking, please get in touch with our support team.
Suspicious and 'other' sites
Lookups of these sites will be redirected to our 'blocked' web site. In most cases, this should look something like this (click here to try for yourself):
In most cases, there will be a section where a team member can request that the site be white listed (unblocked). This will send an email and SMS to the network administrators to allow a speedy resolution. This is not possible, however, in some circumstances, typically in shared offices where a number of companies are using the same Internet connection and more than one of the companies is using the LuJam service. In these cases, the team will have to approach the network administrator directly.
Encrypted sites
A lot of web traffic is now encrypted to protect individual's privacy. This is known as HTTPS, and often a lock will appear in the browser's address bar to indicate a secure encrypted connection. This is a great thing and recommended for everyone that has a company web site. However, when LuJam blocks a lookup to an encrypted site, the browser will often warn that the connection is not secure. This is is known as a man in the middle attack, and will look something like this (click here to see for yourself):
The above is from Chrome, but will look similar in FireFox, Safari, Edge, etc. If you click on the Advanced button, you can clearly see that LuJam is responsible for the re-direction:
At this point, it's OK to proceed and request the site be white listed as per the previous section. However, if it doesn't clearly say *.lujam.com we don't recommend proceeding!
I find this annoying!
Sometimes security and ease of use collide, and this is one of those cases. We've put a lot of effort to make white listing sites very easy, so that the team can very quickly reduce the conflict between these two goals. Within a week, the number of blocked sites should be very low. However, if you feel that you're still not happy, please contact the LuJam support team and we can disable one or more of the underlying feeds.
