Which VPN is safest?

I'm curious to know, which VPN service can be considered the safest option out there? With so many providers available, it's difficult to discern which one truly prioritizes user privacy and security. Are there any specific features or protocols that I should look for when evaluating the safety of a VPN? Additionally, are there any red flags or common pitfalls that I should avoid when making my selection? Your insight would be greatly appreciated.
