What do firewall capabilities provide?

Firewall capabilities primarily provide protection against unauthorized access to networks and data. This is accomplished through various filtering techniques, which may include inspecting incoming and outgoing traffic, allowing or blocking data packets based on predetermined security rules, and creating a barrier between trusted internal networks and untrusted external networks. By restricting access to sensitive information and resources, firewalls help to defend against potential attacks, data breaches, and unauthorized usage, ensuring that only legitimate traffic is permitted.

The other options, while significant in their own contexts, do not directly relate to the core function of firewalls. High-speed data transfer pertains more to bandwidth and network performance rather than security. Enhanced user experience is a broader term that could refer to various aspects of a service or application but does not specifically associate with firewall functions. Data storage solutions involve the mechanisms for storing and managing data rather than providing security. Therefore, the correct focus on unauthorized access aligns directly with the purpose of firewall capabilities.
