Validate your defenses
against real adversaries.
We replicate real-world attack techniques against your infrastructure to find the paths that automated tools miss — before an actual threat actor does.
Boutique offensive security, built on practitioner-led engagements.
Orsu Enterprises is a Costa Rica-based offensive security firm offering nearshore advantage to enterprises across the Americas. Every engagement is manual, hands-on-keyboard, and scoped to your threat model. We don't resell automated scan reports.
Our methodology is built on the Penetration Testing Execution Standard (PTES) and aligned with MITRE ATT&CK techniques, adapted to each client's threat model and regulatory environment.
Targeted engagements for growing companies building real security programs.
How we operate.
Built on PTES and aligned with MITRE ATT&CK, adapted to your threat model.
Reconnaissance
Map your attack surface. Enumerate external assets, identify exposed services, and gather intelligence before a single packet is sent.
Initial Access
Exploit viable entry points — misconfigured services, weak authentication, social vectors. Establish a foothold using real adversary tradecraft.
Lateral Movement
Pivot through your environment. Chain low-severity findings into high-impact paths toward domain admin, production databases, or sensitive systems.
Impact & Reporting
Demonstrate real-world impact on your critical assets and deliver a detailed report with prioritized remediation guidance aligned to your risk profile.
Practitioner-led from the top.
