PrivacyTools provides a baseline considered to be reliable and safe based upon criteria and general consensus. We constantly improve and refine.
We always encourage people within our community to consider their threat model. Not everyone needs "dial up to 11" security which usually comes at the cost of UX, or requires substantial background knowledge.
If the choice is between having something or nothing, we encourage people to think about what they need.
