Is the Synapse protocol safe?

I'm curious about the safety of the Synapse protocol. With the rise of cyberattacks and hacking incidents in the cryptocurrency space, it's essential to ensure that the protocols we use are secure. Can you tell me more about the measures in place to protect the Synapse protocol from potential threats? What kind of encryption is used? Are there any known vulnerabilities that have been addressed? I'd like to have a better understanding of the security features and practices employed by Synapse to ensure that my assets are safe.
