openmonero.com may actually be one of the most secure platforms out there, thanks to its use of non-custodial trade settlements, non-custodial funding, and relatively quick trade finalization (on hour). To date, only about 20k USD of user funds have been stolen, (plus 3k arbiter funds), despite a monthly trade volume of roughly half a million dollars. Had I implemented a setup like haveno, I’d probably have seen at least 2 million USD stolen (good luck trying to refund that).
