Trusted Across Critical Industries
What Sets OnDefend Apart
To stop advanced, persistent adversaries, you need a team that can act like one.
Security Testing Services
To stop advanced, persistent adversaries, you need a team that can act like one.
Network Penetration Testing
We identify exploitable vulnerabilities and attack paths across internal, external, and wireless networks to assess network security risk.
Application Penetration Testing
We assess web, mobile, desktop, and API applications to uncover exploitable vulnerabilities, business logic flaws, and attack paths through dynamic and static testing.
Cloud Penetration Testing
We assess cloud environments to uncover misconfigurations, identity weaknesses, and attack paths across AWS, Azure, GCP, and other cloud platforms.
AI and LLM Penetration Testing
We assess AI and LLM systems to uncover weaknesses that could lead to manipulation, data leakage, or unsafe behavior.
Hardware & Integrated Systems Testing
We assess devices, firmware, and supply-chain integrity to uncover hidden vulnerabilities, undocumented components, and unauthorized communications that lead to compromise.
Red Teaming Services
We emulate determined adversaries to demonstrate how attackers penetrate, persist, and achieve real-world impact across people, process, and technology.
Purple Teaming Services
We run collaborative attack simulations that unite offensive and defensive teams to identify protection, detection, and response gaps, tune defenses, and measurably improve resilience.
Social Engineering Testing
We conduct realistic phishing, vishing, smishing, and physical deception testing to evaluate how people and processes respond to human-focused attack techniques.
