About NOBSEC

NOBSEC Ltd is an offensive cybersecurity consultancy founded by Nikifor Georgiev, a specialist in adversarial security with over a decade of experience across financial services, enterprise, technology, and AI sectors.

The practice is built on a straightforward premise: the most reliable way to understand your security posture is to assess it from the attacker’s perspective. Every engagement is conducted with the rigour and methodology of a real-world threat actor, and delivered with the clarity and professionalism that operations and executive teams can act on.

Prior to founding NOBSEC, Nikifor led penetration testing programmes within global technology and financial organisations — including PCI-DSS scoped assessments, internal red team programmes, purple teaming exercises, and security operations support. Hands-on work spans network compromise, web application exploitation, Active Directory attack chains, and — since the emergence of production AI deployments — adversarial testing of LLM integrations and agentic systems.

Based in the European Union, serving clients internationally. Engagements are delivered remotely or on-site as required. Operating from the EU provides familiarity with European security, privacy, and regulatory frameworks while supporting organizations worldwide.
