How private is the secret network?

Can you elaborate on the level of privacy offered by the secret network? Are users' transactions fully anonymous, or are there still traceable elements? What measures are in place to ensure that personal information remains confidential? Is there a risk of external intrusion or hacking, and how does the network address those concerns? Is there a way to verify the authenticity of transactions while maintaining privacy? Additionally, does the network comply with any relevant privacy regulations or standards?
