We've got some great deals going on right now exclusively for our online customers... chat now to hear more! A guide to VPN protocols,Author: Sue Poremba,Long before 2020, Virtual Private Networks (VPNs) were among one of the many tools used to secure access to company networks from remote or outside the network locations. However, they took on greater significance when many more employees moved from office buildings to dining room tables. VPNs not only help with employee mobility and business continuity but can also amid rising cyber security threats. These multiple uses are strong drivers behind the global VPN market's growth, with a projected market size of $77.1 billion by 2026. While not necessarily household names, familiar protocols like Secure Socket Layer (SSL) and Transport Layer Security (TLS) are employed whenever you see HTTPS in a browser address bar. A short introduction to the VPN protocols that are behind this security option will help show why it is so important, how the protocols work and the different options which might work best for your organization, especially since public internet connections have become more prevalent and accessible for everybody. VPN protocols explained,VPN protocols are a set of standard specifications for establishing a secure tunnel using encryption, verification and security for data transmission between a device (or endpoint) and another device (or endpoint). For VPNs to be most effective, protocol standards are necessary to build secure ways to transmit data over the public internet which is otherwise open and not secure for sending data. Think of , or encrypted connections that connect to a company's private, secured network. They are used to transmit sensitive data across an unsecured "underlay" network and protect that information from malicious actors. By using VPN tunnels it allows you to transmit data so that it is not directly viewable because it is sent through an encrypted virtual tunnel which makes the data unreadable. To put it differently, sometimes speed and capacity outweigh the need for security. It is worth remembering that not all data transmitted over a network is sensitive or in need of being secured over a VPN. Types of VPN protocols explained,Different protocols are available to meet a variety of user requirements. When deciding what are the best VPN protocols for your organization, it is worth considering:Site-to-site VPN,A site-to-site VPN connects multiple networks, such as a corporate network with multiple branch offices. Internet Protocol Security (IPSec) authenticates and then encrypts individual IP packets. It offers a suite of security protocols that add encryption services to other protocols. This protocol is commonly used for site-to-site VPN tunnels. Layer 2 Tunnel Protocol (L2TP) is often paired with IPSec because, while it creates the tunnel and handles authentication, it doesn't have any encryption. Mobile VPN apps,Mobile VPN apps can help users to protect their phones and tablets, whether they are being used on their mobile data network or on home or public Wi-Fi. One of the most used VPN protocols in this scenario is Internet Key Exchange version 2 (IKEv2). This is because it can facilitate virtually seamless switching between mobile data and Wi-Fi because it automatically reconnects back to a VPN server whenever the connection is interrupted. A newer protocol, for its ability to combine fast speeds with strong encryption security. However, it will only work on devices where you can install apps. Further, it doesn't counter deep-packet inspection so may not be able to work with certain network firewalls. Windows vs. Non-Windows users,Secure Socket Tunneling Protocol (SSTP) is a closed-source VPN protocol that's easy to use on Windows platforms because it's a Microsoft proprietary protocol. SSTP may be a good choice for companies that exclusively use Microsoft Windows. is an open source protocol and supported by many VPN services. It bundles different protocols into a library for various encryption methods, which are beneficial for stable connections and connecting to remote servers. However, it doesn't run natively on Windows, so your organization will require third-party software if you use Windows. Understanding what operating system or computer platform is being planned for use in the near future is critical in this decision. Proprietary VPN protocols explained,Some VPN service providers use existing open-source protocols as the basis for . For example. However, they don't offer the same level of transparency because they have added proprietary features, so users are unable to tell what has been changed from the original open-source protocol. This can make validating their level of security difficult, if not impossible. Your needs will determine the best VPN protocols for your organization; or even if a private network is a better option. Securing data transmissions is the primary reason for using a VPN; the devices you use and the type of data you exchange will play a large role in the VPN protocol you choose. The other option: MPLS,Multiprotocol label switching (MPLS) provides a secure option because it handles data at the packet level and uses labels rather than network addresses. The labels, which are allocated to each unit of grouped data (or data packet), control the transmission path. It's fast, secure and scalable. Its biggest downside is cost, but the entire MPLS network for an organization is a private network managed by a service provider, such as Verizon, who provides network performance and availability guarantees. that bypasses public networks and the network is designed to grow as the business grows. MPLS is used by many enterprises and government entities as their foundational core network technology.

Learn moreWhat is a Wide Area Network (WAN)?
What is a Wide Area Network (WAN)?,It's about good connections for your growing application demands. Like your most goal-driven team members, data needs a clear path and the right clearances to cross the finish line. A wide-area network (WAN) is your data's highway across the digital landscape. It provides an avenue between your digital resources, such as hardware and software, and your users. Your data is like your users on the network, with things to do and places to go. If the road users take (your WAN) is pitted, narrow, gravely and single lane, the trip will be slow and possibly hazardous. If the road is a modern thoroughfare, the ride will be smoother, faster, more direct and safer. WANs that work well are built for reliable, high-impact communications. They allow businesses to route data — efficiently and cost-effectively — to and from users and sites, near and far. Just as with roads, WANs come in many configurations. Understanding some of the architectural key points can help inform decisions about your network investments. What does WAN mean, and what does it do?,A WAN is little more than an organized set of internet protocol (IP)-based connections that allows you to move data among distributed teams and devices. When you send personal emails, videos, images or text, the data files are generally simple and small enough to edit, save and share electronically. But things can get complicated when the connections that move this information multiply to accommodate more employees, office locations and cloud- or server-based applications. WANs are controlled-access telecommunications systems that are designed to efficiently transmit larger amounts of data, enabling network connectivity to a wide area. That area might be geographical, as with field offices, high-capacity in terms of processing power and users, or both. What are the advantages of WAN over LAN, and what's the difference?,If your business operates out of your home or a small leased space, you've probably linked together a couple of computers, a printer and a router/modem combination to get online. You also probably have a physical (usually Ethernet) or Wi-Fi link. This is a local area network (LAN) configuration. As your business grows, you need more bandwidth to handle more types of files more quickly and securely across greater distances. A WAN is usually the network that ties local systems together. With a WAN, your LANs and teams can connect to companywide databases and tools that facilitate conferencing, marketing automation, customer relationship management (CRM) and other business operations — all of which are beyond the LAN's scope. How does WAN work?,WANs can use different types of connectivity and technologies to bridge their various parts. WAN operators often employ virtual private networks (VPNs) to interconnect locations and devices more securely. A virtual private network is important because data handled by IP-based WANs may become vulnerable as it moves across the internet. As businesses grow, many are faced with aging network infrastructure and convoluted architectures resulting from technologies that were added over the years. To boost productivity and profitability, they may need WANs that use both wired and wireless technologies. Yet implementing both may seem impossible given available budgets and limited technology resources. And businesses may put off potentially game-changing advancements because they are fearful of the risks and costs to their network. Hybrid, wired and wireless networks can lead to delayed or flawed security updates and implementation of business-critical applications. Think of the work involved in retrofitting equipment, alone. Settings must be changed for routers and servers. Phones, laptops and tablets may need new setups. They may even need to be replaced. Software defined wide area network (SD WAN) technology may be the answer to these challenges. What is SD WAN, and how can it help growing businesses?,Software-defined networks (SDNs) are gaining traction because of their usefulness in surmounting complexity and cost obstacles associated with hybrid networking and cloud computing. To streamline disparate networks while getting the most out of pricey bandwidth, more businesses are turning to a type of SDN called . Among its advantages, SD WAN allows businesses to control several network components and processes from a single interface or computer dashboard. SD WAN is hosted and based in the cloud, and is useful for businesses with branch offices and remote employees using a variety of networking methods. Additionally, SD WANs can eliminate many manual operations and the need for expensive circuits to interconnect hybrid networks. At the same time, the technology makes it easier to maximize bandwidth in near-real time. This means that lower priority activity, such as web-surfing for noncritical work, can be sent through inexpensive public IP channels. More expensive circuits can be reserved for mission-critical and sensitive activity involving sales transactions and customer databases. One way to think of SD WAN is to picture vehicles at an intersection on a divided highway. The network's routing mechanisms are like the traffic lights. The drivers are going one way or the other, and taking turns based on the traffic signals. With SD WAN, instead of a traffic light that doesn't respond immediately to changing conditions, you now have a sort of traffic-management genius in control. This highly trained professional uses advanced tools to evaluate traffic flow, vehicle occupancy and other qualitative factors to determine whether the light is red or green in a given direction. Like this pro traffic manager, SD WAN green-lights important, delay-sensitive payloads. Others get the red light, or are routed elsewhere. Everyone gets through the intersection efficiently and safely, relative to their situation and cargo. Are you ready to move from a LAN to a WAN?,If so, you have plenty of options that can meet your needs. Our networking experts can help you evaluate your requirements and find a solution that fits your budget and ambitions.
