The Offensive Security Initiative (OSI) is a cybersecurity team specializing in offensive security, red teaming, and threat simulation.

Originating from the foundational work of the SYN team (Shadow Syndicate), OSI was established to formalize and expand on a shared commitment to excellence in ethical hacking, adversarial analysis, and security research.

Our team is composed of experienced security engineers, penetration testers, and cyber operations professionals with a background in enterprise security, infrastructure design, and exploit development. With roots in real-world offensive security and experience across diverse environments, OSI is a place for those who thrive on understanding threats from the inside out. We collaborate to explore complex attack paths, sharpen our skills, and push the boundaries of what’s possible.

OSI operates with a focus on realism, integrity, and continuous improvement. Through structured testing engagements, tool development, and internal training, we aim to raise the standard for offensive security capabilities across the board.

We believe that effective defense begins with understanding the offense. Our goal is to bridge that gap—providing clear, actionable insight into vulnerabilities and attack paths, and helping clients build stronger, more resilient environments.
