How does a virtual private network (VPN) work?A VPN extends a corporate network through encrypted connections made over the Internet. Because the traffic is encrypted between the device and the network, traffic remains private as it travels. An employee can work outside the office and still securely connect to the corporate network. Even smartphones and tablets can connect through a VPN. Show
What is secure remote access?Secure remote access provides a safe, secure way to connect users and devices remotely to a corporate network. It includes VPN technology that uses strong ways to authenticate the user or device. VPN technology is available to check whether a device meets certain requirements, also called a device’s posture, before it is allowed to connect remotely. Is VPN traffic encrypted?Yes, traffic on the virtual network is sent securely by establishing an encrypted connection across the Internet known as a tunnel. VPN traffic from a device such as a computer, tablet, or smartphone is encrypted as it travels through this tunnel. Offsite employees can then use the virtual network to access the corporate network. Connectivity Connectivity Virtual private networks (VPNs) create a tunnel between a private network and a public network, allowing users on the public network to send and receive data as if they were directly connected to the private network. VPNs have long been a popular choice for consumers seeking more privacy in their everyday Internet browsing, but the use of VPNs in the business sector has exploded in recent years. This is especially true since March
2020, when VPN usage skyrocketed by 41% in a single month, according to industry research. With our distributed workforce growing exponentially over that time, the need for secure remote access to data, applications and services became a more urgent. VPN protocols determine exactly how data is routed through a connection.
These protocols have different specifications based on the benefits and desired circumstances; for example, some VPN protocols prioritize data throughput speed while others focus on masking or encrypting data packets for privacy and security. 5 Common VPN ProtocolsThere are two main approaches to VPN functionality: 1) two protocols are used (one protocol to move the data through the tunnel and one protocol to secure that traffic); or 2) one protocol is used for both data transfer and data security. Here are five common VPN protocols and their primary benefits. 1) PPTP TL;DR: fast data speeds, wide support, many security issues 2)
L2TP/IPSec TL;DR: widely used, good speeds, easily blocked due to reliance of UDP on single port 3) OpenVPN TL;DR: open source, strongest encryption, slower speeds  SASE, why do we need it? Streamlining and improving remote access for distributed workers is a challenge facing many organizations today. SASE may be the answer. View 4) SSTP TL;DR: good security, difficult to block and detect, great support for native and third party clients 5) IKEv2 TL;DR: fast, mobile friendly, network switching capabilities, open source options, great support for native and third party clients The Purpose-Built VPN ProtocolSeveral years ago, NetMotion engineers determined that while standard security protocols meet the needs of mobile users, there simply wasn’t a delivery protocol reliable enough for the variable and unpredictable conditions of wireless environments. So in developing NetMotion Mobility, we built our own. There are two main components of the Mobility VPN: The Mobility server and the Mobility client. These components communicate using a proprietary, secure, guaranteed delivery protocol called IMP (Internet Mobility Protocol) and RT-IMP, a version of IMP optimized for real-time traffic such as voice and video. Both IMP and RT-IMP run over UDP and on wireless networks, they provide TCP-like reliability with the performance advantages of UDP. The Mobility client and server use a transparent, transport level, proxy architecture to isolate all tunneled IP flows from changes in the underlying physical wireless network. This ensures that the TCP connections for tunneled applications remain connected across network roams and other disruptions in network connectivity. Mobility uses industry-standard encryption and authentication protocols as well as FIPS 140-2 validated and NSA Suite B compliant cryptographic libraries. If your workforce relies on mobile devices and wireless networks to get the job done, there is not a better option than NetMotion’s purpose-built mobile VPN—from a technical standpoint or end-user perspective.

What technique does a VPN use?A VPN works by using encryption protocols to funnel all your internet traffic through an encrypted tunnel — a virtual private network —between your computer and a remote VPN server. This hides your IP address and secures your data, preventing others from intercepting it.
How are VPNs used to secure data?A VPN connection establishes a secure connection between you and the internet. Via the VPN, all your data traffic is routed through an encrypted virtual tunnel. This disguises your IP address when you use the internet, making its location invisible to everyone. A VPN connection is also secure against external attacks.
What is VPN a secure connection for remote access?A remote access virtual private network (VPN) enables users who are working remotely to securely access and use applications and data that reside in the corporate data center and headquarters, encrypting all traffic the users send and receive.
What is a VPN and how does it protect the data transferred over a wireless network?VPN stands for “virtual private network” — a service that protects your internet connection and privacy online. It creates an encrypted tunnel for your data, protects your online identity by hiding your IP address, and allows you to use public Wi-Fi hotspots safely.
