The market for Voice Over IP (VoIP) equipment sold to corporations and other enterprises, including phones, hardware and software, grew 78 percent to $3.07 billion in 2004, according to Synergy Research Group, and is seen rising to $4.42 billion this year. By 2009, it should represent nearly $11 billion in sales.

  With the growing deployment of VoIP, enterprise and service providers face a network security challenge in dynamically allowing VoIP traffic through a range of firewall ports permanently left open for real-time connectivity. Leaving a range of firewall ports wide open for VoIP traffic is also an invitation to malicious network traffic and an unguarded door against hackers. The best way to solve this issue is with Fortinet’s series of Unified Threat Management (UTM) systems featuring FortiOS?. FortiOS Operating System uses an advanced method of content inspection and pattern recognition to dynamically open up a single port, and then close it after the call is completed. It inspects different VoIP protocols including H.323, Session Initiation Protocol (SIP) and SCCP (Skinny) call-signaling protocols used by VoIP systems.




Traditional VoIP Security Solution with Firewall Configurations

  Problem: Traditional firewalls require a permanent range of vulnerable ports be opened to support latency-sensitive VoIP traffic - they are always open and provide a door for unsecured and unauthorized access. This leaves the VoIP switch and entire IP infrastructure vulnerable to damaging attacks and costly downtime.


Fortinet’s Secure VoIP Solution

Solution: Fortinet’s VoIP firewalls work with the industry’s widest range of VoIP offerings and understand H.323, SCCP and Session Initiation Protocol (SIP) signaling and communications protocols to dynamically open only the ports needed for the duration of the call. Only the traffic for that session is allowed since the Fortinet firewall is session-aware at all times. Once the call completes, the ports automatically close for maximum security.



"Securing our customers’ VoIP conference calls is a top priority for Polycom and we are excited that our work with Fortinet has enabled secure, real-time UCC calls for our customers through the interoperability and seamless integration of FortiGate systems with PathNavigator."

- Ed Ellett, senior vice president and general manager of the Video Systems Division at Polycom


"After examining the various options, the Anexeon and MAS Enterprises offering (using Fortinet) has the most promise for our organization,"

- Russ Ketchum, director of Information Technology, The Four Seasons


Fortinet developed its H.323 approach co-operatively with Polycom’s videoconferencing technology. Polycom UCC products now work with Fortinet’s FortiGate UTM Security Systems to protect customers’ video, data and voice traffic against common real-time traffic security concerns including: registration hijacking, server impersonation, message tampering, session tear down and denial of service (DOS). Another advantage of the FortiGate solutions for video conferencing is that the security provided is transparent to end users. There is no need to make any changes to video systems to take full advantage of Fortinet’s new H.323 firewall NAT traversal feature set.

For SIP-based VoIP security, Fortinet is working with several partners including Anexeon Communications, a leading VoIP service provider focused on next generation communication services for businesses. Anexon and their partner MAS Enterprises have found Fortinet to be a leading network security system vendor that can be certified to operate with Anexeon Communications’ national VoIP service. MAS Enterprises has already leveraged Fortinet’s SIP solution to ink a new agreement with The Four Seasons Las Vegas for a VoIP (voice-over-IP) trial at its Four
