well, a firewall could do it, but an Intrusion Prevention System is the more obvious answer.

IPS (Intrusion Prevention System)- A dedicated device or software running on a host that automatically reacts to any unauthorized attempt to access an organization's secured resources on a network or host. IPS is often combined with IDS, however IDS do not automatically make changes to block or overt traffic.
Intrusion Detection Systems (IDS) are software solutions that automatically analyze all network traffic, assess system vulnerabilities, and identify unauthorized access attempts. They monitor network activity for suspicious behavior and alert network administrators when potential threats are detected. Some IDS can also provide detailed reports and insights to help enhance network security measures. Examples include Snort and Suricata.
Network monitoring software, often referred to as packet sniffers or traffic analyzers, is used to monitor and log packet traffic for later analysis. Examples include Wireshark, tcpdump, and SolarWinds Network Performance Monitor. These tools capture data packets traveling over the network, allowing administrators to analyze traffic patterns, troubleshoot issues, and enhance security by identifying suspicious activities. They can provide insights into bandwidth usage, application performance, and potential network vulnerabilities.
Traffic analysis is a method used by attackers to monitor and analyze network traffic to gather information about its patterns, volume, and behavior. This can help attackers identify vulnerabilities in the network and plan future attacks more effectively. It can also be used for legitimate purposes, such as optimizing network performance and security.
Network-based Intrusion Prevention (NIPS): monitors the entire network for suspicious traffic by analyzing protocol activity.A reactive NIDS can also be called a network intrusion prevention system (NIPS).
An intrusion detection system (IDS) monitors network traffic and system activities for suspicious behavior or known threats. It analyzes data packets and logs against predefined rules and patterns, identifying potential security breaches or anomalies. When a potential intrusion is detected, the IDS generates alerts for administrators to investigate further. There are two main types of IDS: network-based (NIDS), which monitors network traffic, and host-based (HIDS), which focuses on individual devices.
Anomaly-based intrusion detection systems monitor network traffic for deviations from established baselines of normal behavior. They can detect suspicious activities that deviate from the expected patterns, such as abnormal traffic volume or unusual user behavior. Anomaly-based systems use machine learning and statistical analysis to identify potential security threats.
