What Are IT Security Services? (Simple Definition)
IT security services consist of the tools, processes, and professional expertise used to protect an organization’s IT infrastructure from cyber threats. These services help businesses detect, prevent, and respond to attacks targeting networks, endpoints, cloud systems, applications, and sensitive data.
IT security services serve as the backbone of any strong cybersecurity strategy.
Why IT Security Services Are Essential for Modern Organizations
