If you're not a very knowledgeable WP developer, or will be having a non-tech client or similar able to add random plugins, then yes security can be an issue.
Horses for course, as was mentioned above it depends entirely on what the requirements are.
I would have concerns in being able to export all content (seems it limited: http://help.squarespace.com/guides/can-i-export-my-site) and in what backup processes are in place. A "more secure" platform never means "100% secure".

@dave it depends on who you talk to. My business has grown over the past 12 months- but that is with 5+ years of hustle.
Didn't you head off for a year long trip? Maybe that's the issue?
