About us
Offensive security is not a side offering here
Our focus is the attacker's side: penetration tests, alarm tests, offensive development and code security audits. That is what we specialise in. We work independently, free from vendor interests.
How we work
Our focus is understanding precisely where your systems are vulnerable and where they can be strengthened. We assess every finding in the context of your organisation – a vulnerability only becomes a risk when a realistic attacker can reach it.
We do not recommend products we earn money on, and we do not sell assessments you do not need. What we commit to is in the offer – including a retest after every penetration test.
We are based in Wiesbaden in the Rhine-Main area and work with clients across Germany.
Where we come from
Wisp Security GmbH is led by Ben Stuart – a computer scientist from Wiesbaden with a long-standing focus on pentesting and operational IT security. The ambition has stayed the same over the years: making complex systems secure and improving them lastingly through automation.

Alarm tests with RedMimicry
For alarm tests we use RedMimicry, the Berlin platform for breach and attack emulation – we are a partner there. Attacks run realistically and reproducibly – how well SOC, EDR, NDR and SIEM detect them becomes measurable.
