You know that firewalls exist in both as software and as hardware devices. Each has its advantages and disadvantages. In general, the use of software firewalls for home use, personal use and small businesses is recommended, as well as the use of hardware firewalls for medium and large businesses.

Types of Firewall Software 

Firewall software can be built for a variety of deployment options:

  • Hardware: Some firewall solutions will have this functionality available as an offering.
  • Endpoints and Software: This type firewalls will protect user devices and applications from malware and hackers. These are some of the most common firewalls available.
  • Virtual: Many firewall solutions can adapt to a range of virtualized environments.

Firewall Software Features

  • Access Control: Access and authentication rules only allow authorized users to enter the network, and from there, they are restricted to whatever servers and websites are not filtered out.
  • Custom Restriction: Network administrators have the ability to dictate what websites and servers users on the network are allowed to access. This can be set strictly to block non-business-related websites, but it can also be used to block servers or IP addresses of known or potential threats.
  • Alerting: If an unauthorized access attempt occurs, firewall solutions will send an alert to network admins detailing the breach.
  • Automation: Firewall solutions can automate monitoring tasks and rule-testing, leaving time for administrators to focus on more pressing network issues and tasks.
  • Reporting: Reporting can be an incredibly helpful component to a company’s security practices. Some tools will document all kinds of historical data, from logins and access points to penetration attempts and security failures, but others provide little documentation for a network’s security history. If a business has a dedicated security staff, consider getting the tightest security for sensitive data, and invest in a solution with in-depth reporting features that provide insight on vulnerability points, event outcomes, and unapproved access attempts.
  • Integration Capabilities: Various integrations and plugins can provide a vast array of needed functions, from device support and content filtering to data integration and dashboards. Other tools may help security staff build custom dashboards to improve monitoring and reporting. Content filtering is another integration that can prevent users from accessing unapproved websites or visiting dangerous links hidden in emails.
