Securing Enterprise-Wide UC

The new generation of enterprise IP-enabled communications is defined by a shift in the way enterprises view their network - from one of enabling communications to one that unifies communications. These unified communications (UC) blend different types of media (voice, video, chat) and applications (collaboration, conferencing and file sharing) together into a broader user experience than simply a point-to-point, voice-based conversation typical in a traditional TDM architecture.

To take advantage of these rich experiences and yet also ensure that enterprises can continue to use their existing PBXs, ACDs, and other legacy investments to keep costs down, a Session Border Controller is needed to ensure interoperability between SIP and other signaling protocols.

 

Enterprise UC Migration

Intelligent Session Control – Unifying Communications

Many enterprises are constrained by disjointed communications systems–combinations of independent PBX islands, branch offices and newer cloud-based collaboration services. Often, IT organizations would like nothing more than to move to a common platform, but the financial implications require a more gradual migration. Along the way, customers and employees are not interested in the nuances of underlying technology, they just want to have a seamless communications experience.

Creating a Normalization Layer

Ribbon's Intelligent Session Control solution provides a normalized SIP layer that transforms fractured multi-vendor, multi-site, telephony environments into cohesive enterprise-wide unified communications systems with uniform directories, dial plan, user policies, features, and security. The solution centralizes both policy and session management, reducing staff time for adds, moves, and changes. End users can more effectively connect between sites using SIP trunking to reduce intra-company and inter-company communication expenses.

Premises or Cloud

Available as a premises-based solution or as a convenient cloud-based service, Ribbon's solution unifies disparate network elements and delivers consistent user experiences across locations and devices. It can even support connectivity between mobile clients and legacy extensions. Once deployed, the highly scalable and reliable solution can also serve as a foundation for a cloud service or unified communications server, sun-setting legacy hardware.

Multi-site Security and Interoperability

Security is a problem for every organization. However, when an organization has thousands of locations and tens of thousands or hundreds of thousands of employees, security becomes exponentially more complicated.

Conventional security devices, like firewalls, cannot protect unified communications traffic, organizations need to supplement firewalls with a Session Border Controller (SBC). Without the security capabilities of an SBC in place, communications traffic can open-up the network to new threats and vulnerabilities. All of Ribbon's SBCs provide robust interworking for multiple signaling protocols, call admission control to manage traffic levels, and multiple security features to prevent malicious attacks,  protect privacy, and ensure regulatory compliance.

Ribbon SBCs:

  • Deliver complete security for signaling and media, including traffic policing, Denial of Service (DoS) and Distributed Denial of Service (DDoS) attack detection and blocking as well as protection from rogue Real-time Transport Protocol (RTP) traffic.
  • Ensures privacy by encrypting media (SRTP) and signaling (IPSec/TLS)
  • Prevents unauthorized third parties from accessing the corporate network by hiding network addresses and names.
  • Improves interoperability by mediating both media (transcoding) and SIP signaling between different devices or services.
  • Provide TDM-to-SIP and SIP-to-SIP interworking to simplify migration from installed PBXs and interconnected networks to cloud-based services.

Using intelligent SBCs installed in the cloud or at the edge of the enterprise network, the Ribbon secures SIP sessions and protects IP communications infrastructure such as cloud services, PBXs, contact centers, media servers, and thousands of other SIP-based devices. Ribbon’s flexible and extensive SBC portfolio offers a choice for scale and functionality to meet diverse deployment requirements.

As enterprises migrate to public cloud-hosted collaboration, or contact center applications, they still need an SBC to assure security the same as if it were within their physical domain. With Ribbon’s Session Border Controller Software Edition (SBC SWe) or Session Border Controller Software Edition Edge (SBC SWe Edge) you can achieve that goal. In addition, Ribbon Connect can be acquired as a cloud-hosted service to provide security for Microsoft Teams.
