0x3 Security Services overview

At 0x3 Security, we deliver comprehensive and adversary-emulated penetration testing engagements tailored to your organization's unique attack surface. Whether it’s from the perspective of an external threat actor, an insider, or a malicious user abusing a vulnerable application or API, our offensive security professionals uncover and validate real-world security risks—before threat actors do.

We don’t just find vulnerabilities—we provide detailed, prioritized, and actionable recommendations that empower your security and development teams to improve resilience and reduce risk.

Pentesting Services

External Pentest

Our external penetration tests simulate attacks from the internet, targeting your publicly accessible assets . We identify exploitable vulnerabilities an adversary could leverage to gain initial access or pivot further into your environment—without any internal access.

Internal Pentest

We emulate what a threat actor could achieve after gaining initial access—whether from a rogue employee or compromised endpoint. Internal tests focus on privilege escalation, lateral movement, insecure protocols, password reuse, and Active Directory attack paths to assess how far a compromise can spread.

Web App & API Pentest

Our team conducts in-depth testing of web applications using OWASP Top 10 and beyond. We assess authentication, authorization, input validation, business logic, session handling, and custom attack surfaces to discover real threats like SQL injection, XSS, IDORs, SSRF, RCE, and more.

Red Team Engagements

Adversary Threat Simulation

We emulate advanced persistent threats (APTs) to evaluate your organization's detection, response, and resilience. Using real-world tactics mapped to the MITRE ATT&CK framework, our simulations uncover blind spots across your people, processes, and technology—before real attackers do.

Physical Pentest

We test the human and physical defenses protecting your critical assets. By attempting real-world intrusions—such as badge cloning, lock picking, tailgating, and surveillance bypass—we identify gaps in access control, response protocols, and facility security posture.

Social Engineering

We simulate phishing, vishing, smishing, and in-person pretexting to assess your organization’s human layer of defense. Our campaigns measure user susceptibility, raise awareness, and help build a security-conscious culture to reduce the risk of manipulation.
