I haven’t heard of anything new that’s problematic at Wix.
They had a nasty-huge security bug in 2016 (might be what you heard). That’s been fixed according to Wix, though maybe try to find if a third party has confirmed this. I would assume though that if it were still a thing, the original reporter would have called the news again.
For payment, I see one of their options is Stripe, who has a very good name in payment services.
My suggestion is that you be sure you have the requirements very clear before proceeding. The problem with Wix and others like them is that if the customer wants to do something not supported by Wix or whatever site it is then the conversion can be a lot of work. It might not be easy to explain that to the customer. It could get ugly. It could be an opportunity if the customer understands and decides to pay for a conversion to somewhere else.
That is the advantage of WordPress and software like that. It is relatively easy to convert a WordPress site to a different host.
Consider doing this. Give them a fixed price for the analysis. Do just the requirements definition. Then if it becomes clear that it is outside the scope of what can be done using Wix then you can say so and walk away. When they waste a lot of money paid to someone else then you might be the hero.
In fact, hacker attacks are possible on any site. After 2016, the Weeks security bugs were fixed. If you are not sure about the security of your site, then check it with a special tool. This is the best option.
Hi, info2524
Nice question and after your question i did some research about wix websites but I didn’t found any issue related to security but I found some other issue which you can read by this article 5-reason-dont-use-wix. Wish you all the best
That article is over four years old - pretty old by technology standards, which can move very quickly. It was updated in 2015 because:
EDIT (September 15, 2015): The reps at Wix contacted me to vehemently disagree with my post and say I have outdated information.
If it was outdated then, it certainly will be now (although the article does include Wix’s responses). Always look for recent information when researching an issue.
