AI made attacking cheap. What took a skilled hacker weeks now takes minutes. Cantic exists to make defending just as fast, by attacking your systems first and fixing what we find.
Engineers who break things carefully, then fix them.

Four rules we don’t bend.
01
No exploit, no finding. Ever.
02
Nothing runs outside the scope you sign.
03
We measure ourselves in doors closed.
04
We prove the access without touching your data.
