Network protection
Architecture, hardening, visibility, and ongoing protection for the systems your organization relies on.
01Security without the theater
Private testing, technical investigation, and practical protection for organizations that need clear answers—not another generic scan.
02Capabilities
We work at the intersection of systems, software, and real-world consequences. Every engagement is private, authorized, and scoped to what actually needs attention.
Architecture, hardening, visibility, and ongoing protection for the systems your organization relies on.
Focused human testing designed around your environment, your rules of engagement, and material risk.
Assessment of web applications, APIs, identity flows, and the trust boundaries around sensitive data.
Decompilation and software analysis when documentation is incomplete, unreliable, or simply not enough.
Evidence-led investigation of suspicious software, compromised systems, and the decisions that follow.
Original security research, responsible disclosure, and open-source-minded work that moves the field forward.
Read our approachThe DOS difference
Just careful work, clear evidence, and a path forward.
Every engagement is confidential, authorized, and scoped to what actually needs attention.
Careful work and clear evidence, specific to your environment.
Clear priorities and a path forward your team can act on.
03Method
Strong security work starts with context. We learn the environment before we test it, then translate technical detail into decisions your team can use.
Define the systems, goals, constraints, and permissions before the work begins.
Use authorized testing and technical analysis to understand meaningful exposure.
Deliver useful evidence, clear priorities, and practical remediation direction.
04Research desk
We believe useful security research should be responsible, understandable, and capable of making systems safer. Our public work is carefully reviewed before it is released.
