Exfiltra

Exfiltra is an offensive security firm specializing in modern cloud and identity attack surfaces. Registered in Estonia (EU) and operating globally, we work with high-growth technology teams who have outgrown automated scanners and need to understand how their environments would actually be breached.

Our work centers on how real attacks unfold — across cloud infrastructure, identity systems, and the application and AI layers built on top. We combine manual vulnerability research with hands-on hardening, so teams don't just receive a list of findings; they see the attack paths that matter and get help closing them at the root.

Why teams work with Exfiltra:

Cloud & identity depth: We go deep into cloud infrastructure, Entra ID, landing zones, and identity attack paths — the areas where modern breaches most often begin.

Offensive-first expertise: A background in manual exploitation and vulnerability research lets us find the logic flaws and chained attack paths that automated tooling consistently misses.

Beyond compliance testing: We move past generic VAPT to show how a foothold becomes full compromise — the findings that checkbox pentests don't surface.

EU-governed and accountable: As an Estonian-incorporated entity, we operate under GDPR and provide EU-standard Data Processing Agreements (DPAs), giving you clear legal accountability regardless of where your team or ours sits.

Core services: cloud & identity attack path assessments, web & API penetration testing, red teaming, AI application red teaming, and cloud security architecture review.Looking to understand how your cloud and identity environment would actually hold up against an attacker?
