 Virtual private network is the extension of shared or public
network and it acts as a tunnel for exchanging data
securely.
 VPN helps to provide security and privacy to the data that
is to be exchanged [2].
 It helps in avoiding censorship blocks and masks the IP
addresses.
 VPN even helps in hiding the physical location and
encrypting data between the computer and respective
server.
 Another feature of this technology is that it does not log
the browsing activities.
 VPN also allows the users in accessing the various
streaming services.
Introduction

 Lack of Reliability: The first issue that is
faced in the legacy virtual private network
is that there is lack of reliability [1].
 Lesser Speed: The next limitation of
legacy VPN is the less speed of this
technology.
 Lack of Security: Data is often lost in this
technology and hence there is lack of
security.
Limitations of Legacy VPN

 Use of P2P Servers: These servers
remove the issues related to users’ ISP.
 Use of Double VPN Technology: This
technology allows the users to browse
anonymously after connecting to VPN
servers.
 Use of SSTP protocols: SSTP and stealth
VPN protocol provide security to the data
[2].
 Use of Tor Technology: The combination
of VPN and Tor removes the complexity of
ISP security.
Solutions to the
Limitations

Therefore, conclusion could be drawn that
The technology virtual private network is
properly utilized in the corporate
environments. This legacy VPN has some of
the major limitations like security or reliability
and data could be lost. However, with the
help of some solutions, these limitations
could be resolved easily.
Conclusion

 Future VPNs will focus on the multifactor
authentication for users and devices.
 The functions would become completely
automated and thus execution would be
easier.
 VPN would be extremely advanced and
there would be in-built firewalls, thus
stopping the security issues.
