Get guidance for a security situation
When something goes wrong, a lost laptop, a suspicious email, a possible breach, the hardest part is knowing what to do first. This interactive decision tree walks you through what should I do if questions, asking about your situation and guiding you toward the appropriate next steps.
Why a decision tree helps under pressure
In a security situation, stress narrows thinking and important steps get skipped. A decision tree externalises the reasoning: it asks the right questions in the right order and points to the sensible response, so you are not trying to remember a procedure while anxious. It is guidance for common situations, a structured prompt rather than a substitute for professional incident response when something serious is genuinely underway.
