Avoid.The Webinar format in Zoom is intended for meetings where a Host and Panelists address a group of Attendees, but there are settings you can use in your Pro account to replicate a Webinar-style meeting for groups up to 300 people. Lasty, GoToMeeting is probably one of the few products on here I would flat out call AWFUL. If you do go with this product at least get the hosting through Adobe, hosting locally seems to add a high level of slow down to the system and their support of self-hosted users has been subpar. Also, the creation of meeting rooms and telephone/conference line integrations are extremely tedious. The updates they've made to it over the years are quite minimal and its flash-based tech is a growing issue.

Adobe Connect was OK, I used it for years but it's not up to par with the quality I expect from Adobe. While there may be a stand-alone purchasing option It's typically tied into buying a package of products from Blackboard. Blackboard Collaborate has some had some up and downs, they have tried to re-release it a few times with drastic UI changes but it's not something Blackboard has even really nailed + plus obviously, it's tied to an organization using Blackboard as their primary LMS with may not work for you. I'll start with the lesser products Google Hangouts and Skype - while they are generally cheap or free their features are minimal and really not appropriate for anything more the small conversations.

I could probably list another 1/2 dozen vendors beside the ones noted above.

User and Entity Behavior Analytics (UEBA).

Interactive Application Security Testing (IAST).

Integration Platform as a Service (iPaaS).

Distributed Denial of Service (DDoS) Protection.
