About us

Our Mission

We founded Invictus Incident Response to tackle the surge in cloud cybersecurity incidents and the gap in truly effective cloud incident response. As seasoned veterans in cloud security, we’ve seen firsthand that handling complex incidents requires more than just reacting but it demands proactive and expert intervention. Our mission is simple: help you emerge stronger and remain unconquered in the face of cyber adversity – that's the Invictus spirit.

Our Values & Identity

Confidentiality

Incidents can be very sensitive especially if privacy sensitive data is involved. We will never disclose our clients unless the customer wants us to and provides explicit consent. The same goes for data we have access to we are committed safeguarding sensitive information and maintaining privacy.

Trustworthy

Incident Response is all about trust, we pride ourselves on a perfect track record. Oftentimes we are in a power position where we can say anything and the customers will do as we say. We don't take that responsibility lightly we will go above and beyond to gain your trust and to keep it.

Independent

We are a completely privately held company based in the Netherlands. We pride ourselves on the fact that we are completely independent there's no incentive for us to promote or use a specific technology. This allows us to advice you objectively and to make the decision that benefit our customers.

Specialists

We are specialists in cloud incident response, we stick to what we're good at. If you are in need of a penetration test we will happily refer you to another company that is also a specialist in that area. You hire us because we are specialists and not generalists.

Our Cloud Specific Expertise

Responding to cloud incidents is vastly different from traditional incident response—and it’s an area where we truly excel. We began developing our cloud incident response skills nearly 10 years ago, long before it became a widespread focus. This early dedication has given us a competitive edge in understanding the unique challenges of cloud environments. Our commitment to cloud security is demonstrated through our extensive library of open-source tools and published articles on cloud incident response. If you’re looking for experts who understand the nuances of cloud incidents, look no further.
