Information security as a craft, not a sales pitch
SECURITYSQUAD is your trusted partner for comprehensive IT security. Our team of experienced experts is dedicated to protecting your digital assets.
Security from a single source – since 2022
SECURITYSQUAD was founded in 2022 with a clear ambition: to approach information security holistically rather than in isolated solutions. Our 360° approach combines consulting – ISMS, ISO 27001, IT-Grundschutz, NIS2 – with offensive security and managed services into a coherent whole. Vendor-neutral and certified to ISO 27001 based on IT-Grundschutz.
We work with organisations across Europe – from mid-sized companies and the public sector to critical infrastructure and healthcare. What drives us is the ambition to implement security pragmatically and in an audit-proof way: tangible measures instead of paper that ends up in a drawer.
