Gieller Gaa

Gieller Gaa is a Recruitment Consultant at MAM Gruppe specialising in Cyber Defence recruitment across Germany, working at mid level and above within the blue team and defensive security space.

Gieller's focus is exclusively on cyber defence rather than offensive security. The professionals he places are the people who detect, respond to and contain threats — not the ones simulating them. That includes SOC Analysts, SIEM Specialists, Cyber Defence Engineers, Blue Team Specialists and professionals working within security operations and threat monitoring functions. He works with organisations of all sizes across Germany, from technology companies and financial institutions through to industrial corporations and public sector bodies that need experienced defensive security professionals.

Defensive cybersecurity talent is among the hardest to find in Germany's security market. Experienced SOC and SIEM professionals in particular are in short supply relative to demand, and the best candidates are typically already employed and not actively looking. Gieller's approach is direct and relationship-led, building connections with defensive security professionals across Germany so that when a requirement comes in, he already knows who to call.

While Gieller's personal specialism sits firmly in the defensive security space, MAM Gruppe's wider Cyber Security team also covers offensive security disciplines including Penetration Testing, Red Team operations and Security Architecture. If your requirement sits outside the defensive space, the team can still help.

Gieller works alongside Managing Consultant Josh Mooney, Cameron Paul and Tom Brooker within MAM Gruppe's Cyber Security team, whose collective coverage spans the full breadth of cybersecurity hiring in Germany from defensive security specialists through to senior security leadership.

If you are hiring cyber defence professionals in Germany, or you are a defensive security specialist looking for your next role, Gieller is the right person to speak to.
