Hello there, in this post we are going to see some of the best VPN alternatives that you can use to browse the internet safely and securely.
VPN stands for Virtual private network and there are many ways to establish VPN and only one of the way is by using the Best VPN providers. Establishing a secure connection is a trade-off between speed and convenience. That is because encrypting the traffic will cause overhead on the connection.
But we are going to look at some of the best VPN alternatives that you can look up to right now. Here are few:
For authenticity and confidentiality, a TLS connection is perfectly adequate. Usually, the authentication in the VPN acts as another level of security in addition to the authentication in the service you are using. But if you are exposing the connection to the internet, then anyone can see the connection and attack it directly.
The best way to stop it is actually simple. The users just have to authenticate the request before actually passing it through. And the simplest way of doing it is client certificate.
In computing, IPSec stands for Internet Protocol Security. It is a secure network protocol that authenticates, encrypts packets of data sent over an IPv4 network.
As a part of the IPv4 enhancement, IPsec is a layer 3 OSI model or internet layer end to end security scheme. Some other internet security system in widespread, operate above the level of OSI models such as TLS and Secure Shell. IPSec can automatically secure applications at the IP level.
3. Open VPN:
Open VPN has a user-friendly implementation that allows portability across operating systems and different processor architecture, firewall and NAT friendly operation. It also provides dynamic address support and multiple protocol support including protocol bridging.
The principle advantage of OpenVPN’s approach is portability, ease of configuration, and compatibility with NAT dynamic address.
4. SSL Explorer:
SSL Explorer is an open source SSL VPN developed by the 3SP Ltd. It is licensed under GNU and it is partially aimed at small that need remote access to the internal network resource.
It allows the users to connect to internal corporate resources such as intranet websites, network files shares, ‘fat client’ applications, and other data via a regular web server.
SSL Explorer is a software written JAVA. It has a web server that servers web that is used to server secure web pages in back-end network. SSL Explorer is ideally installed in the backend but it can be run as a process along with other processes as well.
5. SSH Tunneling :
In a computer network, tunneling is a secure way of transferring data from one network to another. It involves allowing private network communications to be sent across the public network. SSH tunnel consists¶ of encrypting the tunnel created through an SSH protocol connection. This is ideal for transferring unencrypted data.
Stunnel is opensource. It can be used to give connection to the clients and servers that natively use TLS or SSL. It runs on a variety of OS such as Unix, Windows etc. SSL relies on the OpenSSL library to implement underlying the TLS or SSL protocol.
Stunnel can be used to provide a secure connection to a mail server that already is SSL aware. In such a case, the network traffic from such a traffic passes over SSL to Stunnel application, which transparently encrypts or decrypts traffic. Stunnel will typically be behind a firewall in a secure network.
7. Direct Access:
Microsoft introduced Direct Access with Windows Server 2008 and Windows 7. It allows remote users to access private network whenever they are connected to the internet. This is an alternative to VPN offered to Windows. Direct access is controlled by the administrator using Group Policy and distribute software updates whenever the user is logged in.
This protocol was developed by Microsoft to route network traffic over unsecured networks. It is supported by Linux and Mac OS X as well. This protocol encrypts data in sends in pockets by creating a tunnel over LAN or WAN network. It is easy to configure and anyone with little technical knowledge can also configure it. It is enough for accessing geo-restricted content.
The entire L2TP packet, including payload and L2TP header, is sent with a UDP. L2TP does not provide confidentiality or strong authentication by itself but IPSec is often used to secure L2TP protocol. The packets exchanged within an L2TP tunnel are categorized as either control packets or data packets. Reliability can be obtained by L2TP by using nested protocols running within each session of L2TP.
Hamachi is another but not mainstream VPN server. It is a proprietary centrally managed VPN server, consisting of server management by the vendor of the system and client software. The client adds as a virtual network interface to a computer. When a computer connects using Hamachi, the server instructs the peers to establish or disconnect the tunnels to the computer. The detailed info on how Hamachi works have not made public and therefore it is a good alternative for a VPN.
In this post, we saw some of the best VPN alternatives. It should be noted that the alternatives use VPN like, if not actual VPN, technologies. But they differ in one way or another. Some of the technologies are predecessors to VPN while some borrow some technology from VPN. Anyways, you are given with a short list of VPN alternatives that you can always use for official or private needs.
