Knowledge base

In short: These are write-ups that answer one concrete question end to end: what happens during an attack, what can be done about it, and which setting actually matters. Not general security advice — this is what we tend to write down for a client after an incident or an audit. Each piece stands on its own, and each is usable even if you never hire us.

If there is a question you cannot find an answer to, write to us: the next pieces come from the questions we get asked most.
