Paul Painter, Director, Solutions Engineering

This is the fourth and final installment of our firewall series. Be sure to check out our articles about Network Address Translation (NAT), ACL Rules, and Application Layer Inspection to learn about their roles in network security.

In today’s world, secure communication between geographically dispersed applications and users is paramount. Traditionally, this relied on expensive and complex private WAN connections. Thankfully, Virtual Private Networks (VPNs) offer a faster, more cost-effective solution.

HorizonIQ: Leveraging Firewalls for Secure VPN Connections

HorizonIQ utilizes firewalls equipped with built-in VPN capabilities, enabling you to establish secure connections to various locations and devices. These firewalls typically support two common VPN protocols: IPsec and SSL VPN.

IPsec (Internet Protocol Security) encrypts and authenticates data packets, ensuring confidentiality, integrity, and authenticity during transmission. It’s ideal for connecting firewalls at different locations, such as a hosted server environment at HorizonIQ connected to remote offices or partner networks.

SSL VPN (Secure Sockets Layer VPN) provides a web-based solution for secure remote access. Remote users can connect to the firewall using a standard web browser, eliminating the need for pre-installed software. SSL VPN also allows granular access control, enabling you to restrict traffic types and enforce security requirements (like patch updates) before granting access.

Benefits of Firewall-Based VPNs:

  • Cost-effective: Out-of-the-box, HorizonIQ’s Palo Alto firewalls include SSL VPN for Windows and macOS at no additional cost. Licensing options are available for Linux, iOS, and Android, with features like access policy creation based on endpoint security posture.
  • Easy Setup: VPNs can be quickly configured on existing firewalls, eliminating the need for additional hardware or complex infrastructure changes.
  • Enhanced Security: Encryption and access control features safeguard data transmission and prevent unauthorized access.
