Penetration testing, red teaming, and compliance readiness across networks, cloud, and OT

OnDefend focuses on offensive security testing, covering network, application, cloud, hardware, and AI/LLM penetration testing alongside red teaming, purple teaming, and social engineering operations. Work extends into specialized areas such as Operational Technology (OT) security and an Election Security Program, reflecting testing needs beyond standard IT environments.

Beyond testing engagements, OnDefend supports clients with cybersecurity risk assessments, compliance readiness, and Virtual CISO services for organizations needing ongoing security leadership. The Continuous Security Inspector (CSI) offering and security control validation extend assessment work past a single point-in-time test, while security awareness training and incident response planning round out the practice for clients building longer-term security programs.
