The US government have adopted it in an attempt to protect their secure data, therefore, it is seen as the main player when it comes encryption. The more recent technology is AES and this does not have any known security issues. It is considered to be secure but there are some known security flaws. Many VPN providers choose to use AES or blowfish and 128-bit blowfish is incorporated into OpenVPN. Traffic is difficult to block as it is hard to differentiate between it and traffic that uses standard HTTPS over SSL.Īs it uses the OpenSSL library for encryption it means that it supports a number of cryptographic algorithms such as AES, Blowfish, 3DES, CAST-128 as well as others. It is very easy to configure and alter and even though it works more efficiently on a UDP port it is possible to configure it so that it can run on any port and that include TCP port 443. This is a relatively new form of technology that relies on the OpenSSL library and SSLv3/TLSv 1protocols as well as other forms of technology in order to offer a VPN solution that is both reliable and secure. However, there is a possibility that it could be compromised by the NSA and this could also contribute to its weakness and firewalls that have strict restrictions can prove difficult. It's speed when in comparison to OpenVPN makes it favourable and it can be found on all modern platforms. This is seen to be very secure when it comes to advantages and once again it is simple to set up. Therefore, L2TP/IPsec offers a higher speed when compared to that of OpenVPN. Data is encapsulated twice with L2TP/IPsec and this causes the speed to decrease, however, this is balanced out when encryption or decryption takes place in the Kernel and L2TP/IPsec enables multi-threading. There are no known major weaknesses with IPsec and if it is applied correctly it will offer a certain level of security. This is a port that is commonly blocked by NAT firewalls and will mean that additional and advanced configuration will have to be implemented should it be used behind a firewall. There are possible problems and these are associated with the l2TP protocol using UDP port 500. Just in the same way as PPTP, the setup can be completed quickly and easily.

Many operating systems no have L2TP/IPsec included with it and this is the case for VPN-capable devices. Therefore, it is commonly paired up with IPsec which is an encryptions suite that offers enhanced security as well as privacy. Layer 2 Tunnel Protocol is a VPN protocol which when used on its own does not offer any form of encryption or protection for traffic that flows through it.

There are disadvantages and this is the lack of security and the fact that is has been exploited by the NSA. The advantages of using PPTP is that the client is built into a wide range of platforms but it is also very simple to set up and it works efficiently. However, it is a concern that the NSA has gone so far as to decrypt large amounts of data that is stored, this is data that was encrypted at a time when PPTP was considered secure by security experts. It was common knowledge that PPTP was insecure, but PPTP encrypted communications are decrypted by NSA as standard. However, with this came a recommendation from Microsoft that VPN users should now use LTP/IPsec or SSTP as an alternative. Through this weakness, PPTP was exploited within a couple of days but the weakness has been identified and fixed.
PPTP VS OPENVPN WINDOWS
It now uses 128-bit encryption keys but since it was bundled with Windows 95 in 1999 a number of security weaknesses were found with the most serious being the chances of unencapsulated MS-CHAP V2 Authentication.
PPTP VS OPENVPN SOFTWARE
Set up is efficient and simple and there is no requirement for extra software to be installed. It is a popular choice for businesses as well as VPN providers and for every VPN capable platform or device, it comes as standard. While it is only a VPN protocol, it does rely on a number of different methods used for authentication in an attempt to offer security. Since that moment in time, it has become a standard protocol for internal business VPN. Point-to-Point tunnelling protocol was created through a consortium that was used by Microsoft in an attempt to create a VPN that could be used over a dial-up network. So read on now and get your dose of VPN protocol know how.

In particular, we'll be looking at the pros and cons for each of the following protocols: Today we are taking a look at VPN protocols.

That's why we decided to throw this post together.
PPTP VS OPENVPN FULL
The world of VPNs sure is full of acronyms and words that may make your eyes glaze over at first. Each of these protocols offers different features and levels of security. Common protocols include OpenVPN, IPsec, L2TP, PPTP, SSL & TLS. VPN Protocols are the rules and technologies used to secure VPN connections.
