Background for this topic.
Exposure is the condition in which a system, service, credential, vulnerability, or sensitive information is accessible or discoverable by people or systems that should not reach it. In threat modeling, it describes an attack surface or loss of control—not proof that an attacker has succeeded. Examples include an internet-facing administration interface, cloud storage with unintended permissions, a secret committed to source code, or personal data sent to an unintended recipient. Its significance depends on what is exposed, who can reach it, and which protections remain.
The primary defense is exposure reduction: maintain an accurate asset inventory, remove unnecessary public access, enforce least-privilege permissions and strong authentication, patch externally reachable software, and revoke leaked credentials or secrets. Encryption can limit the value of exposed data, but does not correct an exposed access path. Continuous scanning and log review help identify changes and support rapid containment when exposure is discovered.
Dell's John Roese on Quantum Readiness, Cryptographic Inventory and Sovereign AIQuantum computing poses an existential threat to encryption systems built on asymmetric key management protocols, and most enterprises don't know where their cryptographic exposure begins. Dell Technologies' John Roese explains what to do now.
Netskope's Sanjay Beri on Data Risk, Agent Visibility and Enabling AI SafelyAI adoption has outrun enterprise security, leaving data exposed and controls nonexistent. Sanjay Beri, co-founder and CEO at Netskope, says the answer isn't restriction. It's visibility, context and a culture of enablement.
