Not to disparage WordPress, as it is a popular option for various reasons, but here's another reason I love DNN: Any known security holes get super-promptly filled!
One story currently running about WordPress and a 7 month old MAJOR issue:
A file deletion vulnerability that remains unpatched 7 months after being
reported allows for the complete takeover of WordPress sites and for
arbitrary code execution.
security flaw supposedly impacts all WordPress versions, including the
latest 4.9.6 iteration. An attacker looking to exploit the issue would
first have to gain privileges to edit and delete media files.
the vulnerability can be used to escalate privileges attained through
the takeover of an account with a role as low as Author, or through the
exploitation of another vulnerability/misconfiguration,” RIPS
Technologies’ Karim El Ouerghemmi explains.

Also I read a story a few weeks back that indicated all recent releases of WordPress can be hacked to release email addresses of all user emails. WordPress apparently labels it a feature and refuses to change the behavior! (Sorry I cannot locate the story right now.)
Anyway, thanks to the security team at DNN. You've shown your professionalism with very rapid responses to any issues in the past decade!
