Security Terms

Security terms cover how organizations protect users, devices, networks, applications and data, and how they prove it to auditors, insurers and customers. You will find firewalls and secure access, identity and privileged access, detection and response, email and endpoint protection, physical security, and the compliance frameworks that shape requirements. Vendors in this space often describe overlapping products with different labels, bundle features into platforms, and price by user, device or data volume. Knowing what each term actually means helps you compare like with like, spot gaps between tools, and ask whether a service is monitored by people or only alerts you. Read these definitions before a security evaluation, and see our security solutions for how we help buyers compare providers.
