How did the breach take place?


What data or information was exfiltrated?


When did the incident take place and how long did it take?


Who was the attacker and / or where were they from?

Our service

Our proprietary tech


A fully-fledged emergency response platform that has been optimized for medium and large-scale incidents that require a rapid and detailed investigation and complex situations where the precise nature and scale of an incident are not necessarily known.



A powerful remote forensics tool that is ideal for small-scale incidents that require investigation into computers that are known to be infected.

Our differentiation

Our experience is our key differentiator

We do not apply cookie-cutter consulting methodologies. Our approach is a guideline. We let the evidence lead us to conclusions.


We assign people with depth and breadth of expertise

You will be led and supported by experts, each of which has amassed significant experience having been at the coalface of numerous incidents.


We understand the importance of being cost-effective even when delivering the highest quality

Incidents can be extremely costly when all is said and done. We are sensitive to this and have optimized our approach to maximally leverage remote intervention. Our tools facilitate this process.
