Whitelist-first. Zero trust.
Every other spam blocker starts from a blacklist — a list of known bad numbers. But spammers rotate numbers constantly, so blacklists are always a step behind.
HonuFon starts from zero trust. Nobody gets through unless they're in your contacts or you've approved them. Unknown callers get screened — full stop.
Blacklists never catch everything. Whitelists always do.
