You want this alphabetically for why most corps won't deploy OSS wikis that are stamped for approval by the HN crowd?
1. LDAP support
2. SAML / SSO support
3. RBACLs
4. Auditability that integrates with some Big Corp compliance system (I'm thinking SOX primarily here and why some companies can't use Git for systems that require full auditability just because Git rebase and wipe of the reflog can happen)
5. The fact it's Java-based rather than oh... Erlang or Python is a pro to most enterprises that have hordes of people that have known only Java tooling and languages. Training a bunch of people that are not motivated to learn anything new is insanely hard. PHP could substitute in here as well I suppose.
6. Other software suites that integrate tightly with it. JIRA sucks for a lot of people, too, but it sure beats all the other crap I've had to use at work. I think less than 20% of the people on HN have actually had to use HP Quality Center or Rational ClearQuest on a daily basis for a long time.
7. Vendor is software maintainer. Big Corps would rather work with a single vendor if possible rather than some small consulting companies that install and integrate the software tailored for their environment and then leave pretty much. So unless one of the primary maintainers of I dunno, Redmine, started offering support contracts with a team of professional services folks, there's hardly any actual competitors to the Atlassian suite in the enterprise "more money and not much technical know-how to spend it effectively" software market.
8. A sales team that you can choke to bend to your will with money. Most OSS projects will not take terrible, horrible, ugly feature requests for large sums of money from a single user that are technically bad and tough to support without massive costs - this is how a lot of enterprise software vendors do business and part of how they decline over time (too many one-off feature requests for big ticket customers that create conflicting design requirements to engineer around combined with a shift to sales culture over engineering / innovation culture leading to massive loss of technical talent).
