Fonts don't say anything that specific.
At most, they can give off a broad, general vibe. But in terms of saying anything specific, it's going to depend heavily on context.
For example Bodoni may say 'classic' in general, and when applied to the cover of Elle it now says something more specific: 'high fashion'.
Futura may say 'industrial' in general, and when used by Wes Anderson, it now says 'quirky Bill Murray'.
Fraktur may say 'Old Germany' in general, and when used by Scandinavians with Guitars, it now says 'this is a death metal band'.
Comic Sans may say 'casual' in general, and when actually used in any context, it now says 'we don't care enough about ourselves to pick a decent typeface'.
OK, that last example is a bit tongue-in-cheek. But hopefully you get the pattern.
So you're not going to find a typeface that says something as specific as 'safe, secure data' that type of meaning is only going to come with your help as you apply the particular typeface in context.
