They are designed primarily to control incoming and outgoing network traffic based on an applied rule set and may not be able to detect or block all types of malware, especially if the malware is within encrypted traffic or disguised as legitimate traffic. Effective network protection typically requires a multi-layered security approach that includes other tools such as antivirus software, intrusion detection systems, and security information and event management (SIEM).
