Over 4 billion dollars will be spent this year implementing Voice-over-IP (VoIP) solutions. Yet with every dollar spent, organizations are opening themselves to two dollars worth of risk. VoIP protocols are subject to the same exploitation as e-mail and IM, and favor call quality, cost and convenience over security. As a result, organizations with unsecured VoIP installations are subject to enormous damages from consequences such as service unavailability, eavesdropping and infrastructure infection. Sentinel Complete™ is the only security solution capable of securing VoIP holistically without affecting call quality or network configuration.

In the "old days", traditional telephony suffered from voice and call control data traveling on the same network. This led to "phreaking" and unauthorized calls which forced the phone company to separate voice from the control data. With VoIP, voice and control data are back together again, enabling security breaches and fraud on a wide scale for unprotected VoIP infrastructures. In addition, unlike traditional telephony, VoIP phones are "smart". They contain full operating systems that are subject to the same exploits and attacks as normal personal computers. When combined with the access to control data that VoIP offers, a VoIP phone is a powerful attack tool. Imagine all the VoIP phones on your network becoming infected and launching a denial-of-service against your VoIP PBX or computing infrastructure. Sentinel Complete™ combines its intrusion prevention engine with a "VoIP-smart" firewall to blunt attacks and ensure the availability of your VoIP infrastructure!

Due to the design of the two most popular VoIP protocols (H.323 and SIP), traditional firewalls require that you open access to a wide range of ports in order for VoIP to operate. This is because of the dynamic port hopping behavior that H.323 and SIP rely on. As a result, it is nearly impossible to protect VoIP phones and switches with a normal stateful-inspection firewall. Sentinel Complete™ on the other hand is VoIP-smart, dynamically opening and closing VoIP ports as required by phone calls in progress. Enabled by its proprietary content processing-chip, Sentinel Complete™ is able to drastically reduce your vulnerability profile. Further, its intrusion prevention engine blocks attacks and exploits that target your VoIP infrastructure!

Plain old telephone calls are protected from anonymous eavesdropping because they use dedicated circuits for each call. VoIP calls by contrast are easily siphoned off due to the packetized design and shared network nature of Internet Protocol (IP). As a result, encryption is the only way to ensure privacy over an IP network. While some VoIP solutions support built-in encryption, utilizing it drastically degrades call quality and performance. This results in over 97% of all VoIP calls being unencrypted. With Sentinel Complete™, your VoIP communications can be encrypted in real-time with no changes or performance hit to your voice quality. Your VoIP calls can now be as secure as traditional telephony!

A sizable difficulty in securing VoIP is the proprietary nature of the few solutions available. Sentinel Complete™ by contrast, is designed to interoperate with nearly all VoIP vendors. If your solution is H.323 or SIP-based, Sentinel Complete™ can secure it. Also, as with all DigiTar Sentinel™ services there is zero network impact, zero configuration and zero maintenance. Sentinel Complete™ helps your organization reach the potential of VoIP...securely. Sentinel Complete™: Zero Configuration. Zero Maintenance. 100% Security.
