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? Send us a message — we're happy to talk through your setup and where the real risks are.
