SD-WAN Securing Dynamic Networks

Internet Native applications and services are demanding more performance, bandwidth, and flexibility forcing Networks to evolve. Enterprises rely heavily on WAN networks for connecting their branch offices and ensure uninterrupted connectivity to remote locations. They are investing heavily in WAN infrastructure and the resulting maintenance costs. Software-defined wide area networks (SD-WAN), hybrid WAN, network function virtualization (NFV), and application performance management (APM) are some new technologies able to meet these needs.

The unstoppable growth in data volumes due to the Digital transformation is prompting organizations to deploy these new networking technologies to push ever more business traffic over cellular networks and public Internet links pushing it outside the boundaries of an organization. Resulting in the disappearance of the traditional security perimeter and increased number of internet breakouts, thus multiplying the number of potential points of entry for hackers to exploit. It’s a complex, vulnerable environment, that’s both difficult and vital to protect.

MPLS and Ethernet services are still playing an important part in the network landscape, the rise in the importance of these new technologies means that they need to be included in wider networking, with an embedded security strategy that incorporates cellular bandwidth provision and local Internet breakout.

A parallel change can be observed in the role of Security Technology in the new virtualized environment driven by the evolution of Network Technology. Earlier it was easier to design a network with the hardware and software applications in the data center being the focus of the security defenses. As software extends to start controlling the network it will also require to control the security.

The process starts with the virtualization of core network security devices and ends with completely connected and streamline defenses, security controls, responses, and processes around events. Dynamic networking availability translates to data destinations increasingly hosted on virtualized technology in a customer’s network, creating a need for visualized network security function to flex with the network. Any move to a virtualized environment requires it to smooth and seamless, fast and most of all, and automated. ESDS SDWAN services simplify complex challenges helping organizations to quickly streamline or orchestrate a range of security services from basic service management through to full incident response and threat intelligence. For the success of full security technology and process life-cycle, dedicated support from skilled professionals.
