One of the primary benefits of installing a firewall is that it can stop casual hacking attempts. Hackers often try to access networks by scanning random internet addresses for known vulnerabilities. However, a properly installed firewall can ignore these random scans, effectively making your company invisible online. Apart from defending against hacking attempts, a firewall also provides the following benefits: • It prevents ransomware and other viruses from infecting your network • It prevents the theft of sensitive data • It prevents corporate spying • It prevents spam and phishing messages from reaching employees’ inboxes • It prevents website defacement • It mitigates DDoS attacks.
