About Percival

Percival was created to give people a clear second opinion when an email does not feel right.

It combines technical checks with plain-English guidance so users can understand the evidence before they act.

Why it exists

Email scams are often persuasive, familiar and well-timed. Percival exists to help people slow down and review the evidence before they click, reply or pay.

Who it is for

Percival is intended for a broad public audience, including people who may not be confident reading technical email indicators but still need clear advice.

Relationship to Camelot Security

Percival is built by Camelot Security as a product focused on prevention through education rather than fear-based messaging.

The role of AI

AI can help explain patterns and summarise evidence, but it is not infallible. Independent verification still matters, especially when the stakes are high.
