The Remote Authentication Dial-In User Service (RADIUS) protocol is used to provide centralized administration of authentication, authorization, and accounting (AAA) and an industry-standard security infrastructure. RADIUS is defined in RFCs 2138 and 2139 in the IETF RFC Database. RADIUS enables administrators to manage a set of authorization policies, accumulate accounting information, and access an account database from a central location.
CyberGhost has more than 1100 Servers worldwide in 50 countries, making it easy for users to find a fast and secure connection. It does not collect any user data and all traffic information are protected by 128-encryption. Speed is fairly fast, allowing users to stream content, download files and do online shopping. The service comes in three plans, a one-month plan, a six-month plan or an annual package.
In such scenarios, you don’t need a beastly VPN provider with massive bandwidth to secure your email, Facebook, and web browsing activities. In fact, the same home VPN server model we highlighted in the previous section will serve you just as well as a paid solutions. The only time you might consider a paid solution is if you have high-bandwidth needs that your home connection can’t keep up with (like watching large volumes of streaming video through your VPN connection).
To perform our fastest VPN speed test, experts at ReviewsDir have carefully taken a lot of essential factors into account. This includes setting up uniform criteria where each VPN service fighting for the spot in the fastest VPN service list will go through rigorous tests. Since VPN speed issues have a lot to contribute with the location, we have tested our fast VPN performance test from all the seven continents; America, Europe, Asia, and Africa.
ExpressVPN is incredibly fast and super secure, and it can unblock just about any site or service on the internet - including Netflix, Hulu, BBC, and more - with impressive streaming capabilities. It offers servers in over 90 countries, and the 24/7 live chat support is one of the friendliest and most professional. ExpressVPN gives a strong fight to NordVPN, while other VPNs lag behind.
Our Findings: During our VPN speed test, we found IPVanish connection a pretty stable one. With the fastest VPN connection tested on UK server, we have experienced uninterrupted sessions on Netflix and Hulu. There was a slight drop of 18-20% in the overall speed which is normal. The best part which we noticed in our high-speed VPN test is that their servers not only deliver speed but are fully encrypted too, which is great for anyone looking for a combo of speed + security. Read our IPVanish review to discover more powerful feature that comes with the service.
The country connections, meanwhile, matter most to those who want to spoof their location; however, non-spoofers should also make sure there are connections in their home country. If you live in Los Angeles, for example, and want access to American content, then you’ll need a VPN that provides U.S. connections. It won’t work to try and watch Amazon Prime Video over a Dutch VPN connection, because as far as Hulu’s concerned your computer is in the Netherlands.
Security is second to none with NordVPN. Its kills switch feature always monitors traffic between devices and the VPN servers. If for some reason, the data stream breaks, the kill switch will automatically terminate the connection, ensuring that your traffic is protected from prying eyes. Also, a DNS leak feature changes your DNS to point to the VPN server, ensuring that hackers cannot steal data from your default DNS.
As a business grows, it might expand to multiple shops or offices across the country and around the world. To keep things running efficiently, the people working in those locations need a fast, secure and reliable way to share information across computer networks. In addition, traveling employees like salespeople need an equally secure and reliable way to connect to their business's computer network from remote locations.

Put simply, a Virtual Private Network, or VPN, is a group of computers (or discrete networks) networked together over a public network—namely, the internet. Businesses use VPNs to connect remote datacenters, and individuals can use VPNs to get access to network resources when they’re not physically on the same LAN (local area network), or as a method for securing and encrypting their communications when they’re using an untrusted public network.

Betternet is a straightforward app that connects to a VPN with a single click allowing for access when needed. No registration is required and unlike some other free VPN services there are no data caps. All of this is provided by occasional ads and a promoted premium version which are manageable and discreet. The traditional problem with free VPN access has been slow connection speed and while this is still apparent it is not too much of an issue.
As used in this context, a VPLS is a Layer 2 PPVPN, rather than a private line, emulating the full functionality of a traditional LAN. From a user standpoint, a VPLS makes it possible to interconnect several LAN segments over a packet-switched, or optical, provider core; a core transparent to the user, making the remote LAN segments behave as one single LAN.[16]
They even offer the most generous simultaneous connection count, with six simultaneous connections through their network, where everyone else offers five or fewer. NordVPN's network isn't as large as some of their competitors, so if you're trying to obfuscate your tracks, you might want a company with more servers. Otherwise, this company is clearly providing a winning offering.
There are a number of ways to use VPN. The most common scenario is when a remote user accesses a private network across the Internet using a remote access VPN connection. In another scenario, a remote office connects to the corporate network using either a persistent or an on-demand site-to-site VPN connection (also known as a router-to-router VPN connection).
It's not just the bad guys who are watching your traffic. Congress, for example, has granted internet service providers the right to sell anonymized metadata about your activities online. That's unfortunate, for a number of reasons. Fortunately, a VPN makes it much harder for even your ISP to monitor your activity and helps keep your privacy in your hands.
Challenge Handshake Authentication Protocol (CHAP) is an encrypted authentication mechanism that prevents transmission of the actual password on the connection. The NAS sends a challenge, which consists of a session ID and an arbitrary challenge string, to the remote client. The remote client must use the MD5 one-way hashing algorithm to return the user name and a hash of the challenge, session ID, and the client’s password. The user name is sent as plain text.
To access your own home network, you want a VPN server running on either your home router or an attached device (like a Raspberry Pi or even an always-on desktop computer). Ideally, you’ll run the VPN server at the router level for best security and minimal power consumption. To that end, we recommend either flashing your router to DD-WRT (which supports both VPN server and client mode) or purchasing a router that has a built in VPN server (like the previously reviewed Netgear Nighthawk and Nighthawk X6 routers).
Windows being the widely used and the 82% market sharing OS, is one of the oldest and unluckily one of the highly vulnerable to cyber threats. Windows users! Get alert, Windows 10 security won’t protect you from tech-support scammers’ trickery and lies. The FBI reported that it received 11000 tech-support fraud complaints last year with losses totaling more than $15m from 80 countries. It’s high time to protect your cyber world with the best Windows VPN and protect yourself from scammers’ pop-up messages, phishing emails, bogus warnings about fraudulent bank charges or fake refunds, browser lockers, and other malpractices.

iOS, once considered a strong, impregnable operating system, is becoming vulnerable to numerous cyber threats since last few years. Apple has recently confirmed that almost all of its products are affected by the Intel major bug; means any of your most sensitive information could potentially be read. The exact nature of the problem is still unclear, and so does the danger, there are some things we all can do.

When it comes to servers, more is always better. More servers mean that you're less likely to be shunted into a VPN server that is already filled to the brim with other users. NordVPN, Private Internet Access, and TorGuard currently lead the pack with well over 3,000 servers each—NordVPN is at the forefront with 4,875 servers. But the competition is beginning to heat up. Last year, only a handful of companies offered more than 500 servers, now it's becoming unusual to find a company offering fewer than 1,000 servers.
Trusting a VPN is a hard choice, but IVPN's transparency goes a long way toward proving that its customers' privacy is a priority. Founder and CEO Nick Pestell answered all of our questions about the company's internal security, and even described the tools the company uses to limit and track access to secure servers. IVPN goes further than the other leading candidates we considered by being transparent about who runs the service and who is responsible for your privacy.

In short, it's time to start thinking about protecting your personal information. That's where virtual private networks, or VPNs, come in. These services use simple software to protect your internet connection, and they give you greater control over how you appear online, too. While you might never have heard of VPN services, they are valuable tools that you should understand and use. So who needs a VPN? The short answer is that everyone does. Even Mac users can benefit from a VPN.
