Virtual Private Network -
VPN is a
network technology which links the private network over internet
using encryption methods. VPN is generally preferred by corporates, educational
institutions, Government agencies and private citizens to facilitate easy
access of remote users to secured private networks. VPN is economical as it is
much cheaper when compared to private networks, it provides flexibility, not
only that VPN users can maintain their anonymity as well as protect themselves
from being snooped. VPN works on 4 protocols:
§
IP security (IPSec): IPSec utilizes two methods to
encrypt its user’s data :a) transport mode or b) tunneling mode.
Transport mode means encryption of message within the data
packet also termed as Payload. Tunneling mode means encryption of the entire data packet.
packet also termed as Payload. Tunneling mode means encryption of the entire data packet.
§
Point-To-Point Tunneling Protocol (PPTP): This is the
most widely used protocol; PPTP uses the tunneling method
wherein PPTP stores data within the PPP packets which are further stored
inside the IP packets which are transported to their destination.
§
Layer 2 Tunneling Protocol (L2TP): It works on
two major features: L2TP Access Concentrator (LAC) and L2TP
Network Server (LNS). LAC: this is a device which terminates the call and LNS:
this authenticates the PPP packets as seen earlier in the PPTP.
§
Transport Layer Security (TLS) and Secure Sockets Layer (SSL) i.e.
TSL/SSL: This method uses a combination of the authentication
and encryption methods which leads to transportation of the data between
the servers and client.
There are several VPN service
providers which vary in the way the data is secured during its transit over the
public network infrastructure. Out of the various VPN providers, Techworm
brings you the Top 10 VPN service provide you with privacy and data security :
TorGuard:
No logs are monitored. In
addition to a strict “no logging policy” TorGuard also provides second layer of
data security with a shared IP configuration due to which it becomes next to
impossible to trace the user’s IP address. TorGuard VPN has multiple Socks
proxy servers and VPN’s around the world. The entire data is wrapped into
single packet by encryption via tunnel method through secure servers and
then this data is again connected to the BitTorrent cloud which gives it the
second layer of insulation from being attacked. TorGuard currently
maintains 1000+ servers in over 44 countries across the world and are in
continuous expansion. TorGuard retains its control on all hardware though it
seeks partnerships with data centers who can adhere to strict security
criteria. All servers are arranged and managed exclusively by TorGuard’s in
house networking team through a single, secure key. TorGuard advises
its clients to use OpenVPN connections only and for encryption use AES256
with 2048bit RSA for better security.

Mullvad
Logs are not monitored. Here again a
second layer of data security is ensured by making users to share their IP
addresses both for IPv4 and IPv6. Users are normally not monitored
however only in case of extreme network abuse the basic tools are used to tackle
such network exploitation. This service does not maintain any personal
information of the user. It supports BitTorrent. Open VPN using Mullvad client
program is the most secured VPN connection. Mullvad assigns a unique number to each downloaded program. This
account number identifies user’s account which can be used to make payments and
to enable the program to connect. Due to the unique number assigned it helps in
the security of the data. URL : mullvad.net/en
IPVanish
This creates a secure environment for
day to day web usage. Before user logs onto the net, it is essential to
establish IPVanish VPN connection, which will convert entire online data into encrypted tunnel including
emails, data transfers, online banking, instant messaging and all online
browsing. The encrypted data cannot be intercepted by any third party including
ISP (Internet Service Provider). It supports P2P traffic. It
uses OpenVPN, L2TP, and PPTP Protocols for its operations.

LiquidVPN
Logs are not retained. LiquidVPN
uses the ‘Modulating IP’ technology, wherein the user’s IP address is
changed continuously making it very difficult to track the actions of user on
internet. Added to this is the use of shared IPs, great encryption
standards, and a very low starting price. For mitigation of network abuse
the SNMP and Mikrotik Layer 7 firewall rules works at hardware level
and Zabbix and OSSEC at host level. Their data centers are on short term
lease across the world.

BTGuard
This service is based on proxy
service where the user is able to hide their true IP address from the rest of
the world. This is a service specially built for the BitTorrrent users to
protect their anonymity. BTGuard was just a basic proxy service that user
would need to configure to avail the BitTorrent service however
now BTGuard is becoming a handy tool with its easy to install software to
protect their anonymity. BTGuard also has an encryption tunnel
software for users who require special security for their data.
BTGuard stores username, password and e-mail addresses however the IP
addresses are never stored.

BolehVPN
It hides true location of the user by
encrypting and encapsulating the entire data which passes through the VPN hence
making it difficult for the snoopers or the third party to intercept or decode
the internet traffic. Various features of BolehVPN can be listed as : it
protects the user by masking the IP address, the data is encrypted throughout
i.e. to and fro when it passes the VPN server, it accelerates the P2P, It also
hides the true location of user due to which user appears to hail from a
different location and last it also helps users to bypass certain corporate
firewalls. It is based on Open VPN and SSL VPN.

HideIPVPN
It is based on combination of
PPTP, SSTP, L2TP, IPSec, OpenVPN and SmartDNS. It is compatible with
a huge list of operating systems Windows, Mac, Linux, Routers etc. HideIPVPN
offers a very high quality of anonymity to its users on the internet wherein
user can access even the blocked websites, surf the web anonymously, hide the
IP address and encrypt user’s data. HideIPVPN does not restrict access to
any online sites or services. All data going out and coming in via VPN is
encrypted, secured and it also hides IP address which means one can
safely access secure websites without anyone intercepting the connections. The
encrypted data is hidden from user’s ISP and network administrator too which
means only user and the destination will be able to see what is being sent.
SmartDNS service helps the user to access more than 35 online media
services from around the world hence it is ideal for anyone who has limited
cable access to TV channels, by using HideIPVPN user can change their DNS name
and hence get easy access to the blocked TV / media servers.

SlickVPN
An IP address acts as a digital
signature which helps to detect the location of the user to any website or to
the Internet Service Provider i.e. ISP. SlickVPN hides the true IP address
of user by assigning them an anonymous one hence enabling user to hide their
location from snoopers. If any user connects to SlickVPN, a connection
will be created between user’s computer and our servers. SlickVPN encrypts any
data transmissions or online activity so that user’s presence is
anonymous; in addition the connection is also secured by SlickVPN so
that the Internet activity, usernames, passwords, emails, instant
messages, downloads, uploads, etc. are shielded from third party.

Unspyable
This uses an Off-Shore VPN service
wherein VPN encrypts the entire internet connection and creates an encrypted
tunnel between the user’s computer and the server chosen by user from the
preferred list of servers. Now whenever user browses the internet, all the
web sites which user visited would see the address of the remote server and not
the real IP address of the user. Due to the encrypted tunnel between user and
server, user’s IP address is now anonymous. Hence none of user’s
information is available on the local network nor to the local ISP or to
government censors and monitoring. For users who want a higher security
Unspyable also offers the Multiple Hop VPN wherein just as in Off Shore VPN the
data is made to pass through a multiple off shore hops / servers which is very
difficult to crack. Major benefits of this VPN :Provide secure and private
offshore email logs which is not saved or monitored, correspondence is secured
using hot spots, Anonymity of IP address.

NordVPN
This provides a great 256bit AES OpenVPN protection and there
are PPTP and L2TP/IPSec connections available. As soon as user connects to the
NordVPN a tunnel is created between user and the server and all the data in
this route is encrypted. NordVPN is also one of the only VPNs to allow Tor over
VPN and has a double-hop encryption system which cannot be cracked. Tor over
VPN is an advanced privacy solution provided by NordVPN.
The basic principle here : User
first connects to NordVPN server which then routes all traffic through a
widely known Tor network. Here the data is encrypted within NordVPN layer at
the initial stage and later sent to the Tor network. The Tor is more safer for
privacy as the encrypted data is made to route through a few Tor hops and
finally reach its destination helping in maintaining the anonymity of user’s
vital information and also DNS traffic is also routed through the Tor
network user’s will be able to access ” .onion websites” or the hidden websites
just using NordVPN.
