It's not 100% secure. Like any dual-key encryption, it's subject to the classic man-in-the-middle attack. This is why the Windows Zfone app has the addition of a visual key you can read and coordinate with the recipient to determine if a MITM attack is occurring. But only if you know what you're doing.
There is no such thing as an unbreakable system. YOU might not be able to attack it with your limited resources, but someone determined enough to do so, will find a way. N.
