Best Firewall Software

firewall softwareAs more businesses undergo digital transformation, the need to protect data has become more critical. Another factor that is pushing data security to be a priority is the rapid development, higher complexity, and increased prevalence of different cybersecurity threats such as virus, malware, trojans, denial of service attacks, phishing, and ransomware. Firewall software provide a primary defense system by keeping outsiders blocked while alerting you when your own applications are trying to connect outside.

What is firewall software?

Firewalls have evolved over the years as technology and corresponding threats also made improvements. Traditional firewall software that filter data packets, translate addresses, and inspect states have been upgraded by next-generation technologies with more device filtering functions. Next-generation firewalls (NGFW), which can take the form of hardware appliances, software, virtual machines, or a combination of these, now include other security systems such as deep packet inspection and intrusion prevention systems. They are now more thorough in their inspection, smarter in their approach with AI, and affects network performance less.
