Virtualization has transformed the data center over the past decade. IT departments use virtualization to consolidate multiple server workloads onto a smaller number of more powerful servers. They use virtualization to scale existing applications by
adding more virtual machines to support them, and they deploy new applications without having to purchase additional servers to do so. They achieve greater resource utilization by balancing workloads across a large pool of servers in real time—and they respond more quickly to changes in workload or server availability by moving virtual machines between physical servers. Virtualized environments support private clouds on which application engineers can now provision their own virtual servers and networks in environments that expand and contract on demand.
In this Magic Quadrant, Gartner examines the role of SSL VPNs in remote access and the state of the market. Read this report to learn how to evaluate the suitability of SSL VPNs in a range of remote-access use cases.

Every few years a technology comes along that evolves the current approach to become more efficient and cost effective. Software-defined wide-area networking (SD-WAN) connects locations in a revolutionary way, but many “facts” about SD-WAN are more fantasy than reality.
Read “5 Myths About Enterprise SD-WAN” for clarity around the advantages and limitations of SD-WAN and how Forcepoint helps with its implementation.
For anyone that has ever had to worry about connecting a distributed network, software-defined wide-area networking (SD-WAN) is a big deal. It’s a drastic upgrade to the status quo, efficiently connecting locations with existing network technology like commodity broadband and virtual private networks (VPNs).
The old world of collaboration—desktops, wired network connections, virtual private networks, and clunky software—has given way to a new world of collaboration. Today’s generation of mobile devices, wireless technologies, and cloud capabilities has had an inexorable and fundamental impact on how people work together and share information. Collaboration is now device- and network-agnostic. It’s not just about being able to work anywhere and anytime, it’s about being able to connect to any document at any time. Read this CIO white paper to learn how to bridge the gap in the modern world.
A team approach and careful consideration of operational and security issues will pave the way for effective guidance. The drivers are many, but big draws include the potential for greater productivity — giving people anywhere, anytime access to information via devices they’re comfortable with.

Most service providers’ Virtual Private Network (VPN) security delivers little more than a promise to keep each customer’s data separated across a shared infrastructure. What are the risks of this virtual security model and how can it go wrong? This technical paper is prepared from an interview with Senetas CTO Julian Fay, in which these topics are discussed and practical considerations given for using encryption on VPNs to enhance organizations’ data security.

NAC is a multifaceted framework to thoroughly control who and what gets access to network resources, and help keep malware from entering the enterprise. Today, there are huge challenges to implementing as-yet immature NAC solutions on an enterprise-wide basis, including convoluted integration requirements, inadequate inspection capabilities, and weak policy management.

Internet Protocol Security virtual private networks (IPSec VPNs) were once the only options for secure remote access, but worked only site-to-site and were difficult and costly to maintain. Today, Secure Sockets Layer (SSL) VPNs are increasingly replacing IPSec VPNs because they are less costly to manage...

Virtual private networks (VPNs) are the technologies most widely used by organizations today in the provision of remote access to their networks for employees, business partners and suppliers. Of the VPNs available, IPSec (Internet Protocol Security) VPNs provide the most complete remote access solution, although they have traditionally been seen as costly and difficult to deploy.
The impact of cloud computing and software-defined networking (SDN), including network virtualization, has convinced large enterprises and customers building private, public, and hybrid cloud networks to consider new approaches to help them meet their current and future data center switching needs. Data center switching platforms are constantly evolving, delivering increasingly better performance while simplifying network operations.
