Kytheos is a product line from the cybersecurity company Soft Task that builds AI-powered security tools which explain cyber threats in plain language. Its first product, Kytheos Guardian, is a free tool that checks whether a link, email, or file is a scam, phishing, or malware — and explains why.

Why Kytheos

Security that explains itself.

01

Signals make the decision

Independent checks — reputation, domain age, look-alike detection, credential paths — are computed first. The verdict follows the evidence.

02

AI explains the decision

The model translates those signals into plain language. It never invents confidence the signals don't support.

03

You know what to do next

Every answer ends with a clear, specific next step — not a colour-coded score you still have to interpret.
