Advanced Threat Protection (ATP) is a type of security solution that is designed to detect and prevent advanced cyber threats, such as zero-day attacks and targeted attacks. ATP solutions typically use a combination of technologies, such as machine learning, behavioral analysis, and sandboxing, to analyze and identify potential threats that may not be detected by traditional security systems.

ATP solutions are typically used to protect against threats that are specifically designed to bypass traditional security measures and are often used in conjunction with other security measures, such as firewalls, intrusion prevention systems, and antivirus software. 

ATP solutions are typically deployed as hardware appliances, software solutions, or cloud-based services, and can be used to protect networks of all sizes, from small business networks to large enterprise networks. They are an important part of a comprehensive security strategy, as they can help to protect against the most advanced and sophisticated cyber threats.
