See how much a control actually helps
A security control is an investment, and whether it is worth it depends on how much it reduces real risk, not on whether it exists. This simulator lets you test control effectiveness by modelling how a control changes the likelihood or impact of the risks it addresses, so you can reason about which controls earn their place.
Why effectiveness, not presence, is the question
Having a control checked off a list says nothing about whether it works. A control that catches ninety per cent of attempts is worth far more than one that catches ten, and one that only partially reduces impact may still leave unacceptable exposure. Simulating the effect, how the risk distribution shifts once the control is in place, turns a yes-or-no compliance question into a quantified one: is this control moving the risk enough to justify its cost.

Frequently Asked Questions
What does it simulate?
How a security control changes the likelihood or impact of the risks it addresses, so you can see how much real risk reduction it delivers.
Why is presence not enough?
Because a control existing says nothing about whether it works. One catching ninety per cent of attempts is worth far more than one catching ten.
How does it help prioritise?
By showing which controls move the risk distribution most, so you can invest in the ones that deliver real reduction rather than those that merely tick a box.
Is this a substitute for testing controls?
No. It models effectiveness to support decisions; verifying a control actually performs as assumed still requires real testing.
Is my data uploaded?
No. The simulation runs entirely in your browser.
