About DarkLineSecurity.
DarkLineSecurity is a specialized boutique cybersecurity consultancy based in Austria, serving international clients, including businesses in the United States. We focus on external exposure intelligence, brand protection, and authorized security testing of web applications, APIs, and smart contracts, and we show companies what attackers can already see about them before it turns into financial or reputational damage.
Why the outside view?
Most successful attacks on small and midsize businesses don't start with sophisticated exploits. They start with what's publicly visible: a deceptively similar domain, identities exposed in third-party breaches, or information that never needed to be public.
Exactly these risks can be identified passively, without expensive projects and without touching production systems. And when an application itself needs scrutiny, we test actively: as an authorized penetration test or smart contract review, with a clear scope and written approval.

What we stand for.
Clarity over alarmism
We don't sell fear. A finding is only a risk if it's relevant, and that's exactly how we communicate it.
Specialization over sprawl
Exposure intelligence, brand protection, and security testing. For everything else, we honestly point you to the right specialists.
Evidence over claims
Every statement in a report is backed and verifiable. We don't invent metrics, customers, or certifications.
What we are not.
DarkLineSecurity is not a generic IT provider, not a managed security provider, not a 24/7 security operations center, and not an incident response service. We don't sell AI tools either: AI is part of our methodology, not the product.
That boundary is deliberate. It lets us work our core fields at full depth, and it lets you buy a clearly defined service with a clear outcome.
