What Are Cybersecurity Tools? 

Cybersecurity tools are software, hardware, or combined systems designed to protect digital assets from a variety of security threats. These tools help monitor systems for potential risks, respond to vulnerabilities, and take preventative actions against attacks.

Cybersecurity tools are essential for safeguarding personal, organizational, and governmental data from theft, corruption, or loss. 

How Cybersecurity Tools Function 

These tools function by detecting, analyzing, and mitigating threats. For example, antivirus software scans systems for malicious programs, firewalls block unauthorized access, and encryption tools secure sensitive information.

Cybersecurity tools also offer proactive protection, such as intrusion detection systems (IDS) that identify unauthorized access attempts.
