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.

Exfiltra found valid security vulnerabilities of various severities after performing thorough and comprehensive tests. The team's findings were accurate, well-documented, and presented in a way that made them easy to consume. Exfiltra established themselves as a trusted partner for the client.
BACKGROUND
Introduce your business and what you do there.
I’m the SRE infrastructure manager at Tune, an affiliate marketing platform that gives advertisers full control over their partnerships, data, and workflows. We enable brands to build and manage customized affiliate programs with reliable technology and support.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Exfiltra?
We hired Exfiltra to perform annual penetration testing of our platform to give us an outside perspective on the security posture of our customer-facing software systems.
SOLUTION
What was the scope of their involvement?
The objective of the engagement was to test the Tune platform for security vulnerabilities based on a variety of industry-standard approaches and techniques that test external and internal threat scenarios that resemble customers and affiliates interacting with the platform. Exfiltra provided a comprehensive and actionable report of findings. The report covered approach and methodologies, detailed documentation on the individual findings with recommendations for resolution and mitigation of risk.
What is the team composition?
We worked with 2–5 teammates from Exfiltra.
How did you come to work with Exfiltra?
We found them through a referral. We chose them because their pricing fit our budget, they had a great culture fit, they offered good value for the cost, and their company values aligned with ours.
What is the status of this engagement?
We worked together from July to September 2026.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Exfiltra found valid security vulnerabilities of various severities after performing thorough and comprehensive tests that were based on context and scenarios from business processes performed on the platform. The findings were accurate, well-documented, and presented in a way that made them easy to consume as input for remediation and mitigation efforts, increasing the effectiveness of our security efforts.
They discovered one critical vulnerability and multiple items of lower severity. The experience of this successful collaboration between our security staff and Exfiltra highlighted the value of ongoing collaboration with a strong external partner. Frequent communication, sharing context, and providing ongoing feedback improved the process and outcomes.
Although the project just finished and the long-term impact is yet to be seen, the report and the low number of findings immediately increased our confidence in our efforts. The learnings during the process from the collaboration will lead to changes in how we go about discovery and reconnaissance. Exfiltra has established themselves as a trusted partner we will continue working with, be that in recurring efforts similar to this one or in projects where they would take on a consulting role.
How did Exfiltra perform from a project management standpoint?
The project management was excellent. Timely and frequent communication via email and messages ensured continuous progress and efficiency and provided clarity of the process and transparency.
What did you find most impressive about them?
The collaboration between Exfiltra and our security staff was extremely effective. It was driven by mutual understanding and flexibility. They asked the right questions and suggested next steps during any phase of the effort (initial negotiation, planning, preparation, execution, and follow-up).
Are there any areas they could improve?
No, there was nothing I could come up with.
