If you are the prey, then a 'web' is something that entangles you, traps you, and eventually kills you.

Only the predators--the spiders--know which strands of the web are safe to walk along.

We have a 'world wide web' -- seems like a missed opportunity to name some ultra-safe, encrypted, secure, anonymous web-walking browser 'spider' or 'arachnid'
