I'm not sure how much help this is, but it should be possible to "section off" certain levels of the wiki for certain user groups (you could possibly make a "user group" for every individual user if you needed to)
What you would do, for sections with info so sensitive that only one or two people should have access is simply to restrict everything, even the ability to read the page (including the page source) in any way, to just those user groups you specify. This would effectively secure that information to just those parties alone, though this would require manually toggling settings for each user group, which would be extremely tedious yet doable.
That security hassle aside, MediaWiki is probably the best option you have for handling such a large amount of content, and while I'm no expert on wiki security, it is probably the most well featured wiki when it comes to additional security options and extensions you can install and configure, and I would highly recommend using it.
In fact, I found an extension that should serve your security needs well in blocking even page sources from being viewable (for your needs, this would be essential)
https://www.mediawiki.org/wiki/Extension:ProtectSource
You also want this extension, just to close loopholes in the above extension, such as the Special:Import/Export special pages:
https://www.mediawiki.org/wiki/Extension:DisableSpecialPages
I'm not sure what else you need at the moment, but you should check out all the page permission and security extensions on MediaWiki.org, not to mention all the page permission documentation available to determine how feasible the level of security you desire is:

Hope that helps.

Hello,
(sorry for my poor English.)
This is probably a recurring question.
I work for an IT company of around 80 000 employees and we would like to build an enterprise wiki, where we will put all our technical documentation (how to, troubleshooting, scripting, etc.).
80 000 employees, but this wiki will be for 1000 of them. It may generate a minimum of 200 000/300 000 pages + images + etc.
You have to know that in some of our documentation, we have usernames and passwords, or maybe firewall configuration, etc. for different customers.
Of course, I know that Mediawiki cannot provide a per page/category security (at a read level): my understanding is that Mediawiki is "Read all pages" or "Access denied to all pages". nothing in between. So we cannot restrict view of some documents to a specific group.
Fine.
So let's say that it's not a problem and that all our technicians will be able to read all the technical documents, of all our customers.
Someone told me that we just don't have to put some confidential informations in our wiki documents (no user/password/confidential config/etc.).
Fine. But where ? If we don't put them in the wiki pages, it means that the users will have to go in the wiki for the basic informations, then go on another tool to have the confidential info.
Now, my question: how do you manage this ?
I really love Mediawiki and would like to implement it in our business, but I haven't enough information on how this can be implemented in the reality of a business.
And no: no budget to buy something like Confluence.
I have try Dokuwiki, XWiki, Tiki, MoinMoin, many others. I love Dokuwiki too, but wasn't sure enough it was a strong tool to be able to manage that amount of pages/images/. Anyway, I always come back to MediaWiki. I don't know why.
Best regards,
Pierre
