Can a scam slip through undetected?

Yes. Well-crafted, personalised, or brand-new scams may not match our rules yet — especially voice clones, deepfake video, or messages with no obvious keywords. We are designed to fail conservatively: warn when patterns match, stay cautious when unsure, and never falsely reassure you with a 'safe' label. Treat Digital Guardian as one layer of defence alongside your own verification, caller ID apps, and bank security settings.
