Personal firewalls are security programs installed on an individual computer. They protect by controlling the data to and from other computers, allowing authorized communication while blocking potential threats. They work as a barrier between your personal computer and the external cyber world, monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. Personal firewalls help to detect and prevent unauthorized access, thereby safeguarding your personal data from potential threats.
