IT Security refers to products and services that protect digital systems and data from cyber threats and unauthorized access. This category includes markets that focus on network security, identity management, data protection, and cloud security, enabling organizations to reduce risk, ensure compliance, and operate securely in a digital world.
Infrastructure monitoring tools capture the health and resource utilization of IT infrastructure components wherever they reside (e.g., in a data center, at the edge, or IaaS or PaaS in the cloud). This enables I&O teams to monitor the availability and resource utilization data of physical, virtual, software entities, and AI systems — including servers, containers, network devices, database instances, hypervisors, storage, and basic application monitoring. These tools collect data in near real time and perform historical data analysis or trending of the elements they monitor.
Gartner defines WAN optimization tools as products that improve the performance of applications running across the WAN as well as reduce WAN service expenses. WAN optimization solutions continue to evolve, and now support four high-level needs: improving the response times for users of business-critical applications over WAN links or mobile connections; assisting in maximizing ROI for WAN bandwidth; optimizing data-center-to-data-center (DC-to-DC) traffic for faster storage replication and synchronization; and assisting in directing traffic across multiple WANS, such as a hybrid WAN or public cloud connectivity.
