Radware Dives Into SIP

Radware Ltd. (Nasdaq: RDWR) is applying its application-delivery expertise to Session Initiation Protocol (SIP) with a new product suite aimed at helping developers build carrier-grade Web and voice-over-IP (VOIP) services.

The SIP Director product suite, announced yesterday, builds on the company's AppDirector platform and is "tuned for the challenges of delivering applications on top of the SIP protocol," Radware CTO Amir Peles says. (See Radware Intros SIP Director.)

SIP Director sits in front of applications and acts to ensure availability, reliability, and security, according to Peles.

Furthermore, he adds, because developers need only worry about making sure their applications work with the SIP Director, the platform can accelerate the deployment of SIP-based applications and minimize interoperability testing.

In shoring up SIP, the company may have found a good new niche. "Radware is very early and has correctly identified the need to bolster SIP as a network protocol to make it clear that it's going to be reliable," says IDC analyst Elisabeth Rainge.

Rainge adds that Radware has "a very interesting and significant opportunity" in enterprise and carrier customers. While enterprises will more quickly recognize the need for improved control of SIP applications, she says carriers will also see a need to deploy platforms like SIP Director.

Peles notes that today all the leading vendors of business application servers, including Oracle Corp. (Nasdaq: ORCL), BEA Systems Inc. (Nasdaq: BEAS), IBM Corp. (NYSE: IBM), and Microsoft Corp. (Nasdaq: MSFT), are porting their technology to SIP-based application servers.
