The page acts as a single gateway to the other services available on the secured network. This type of SSL VPN gets its name because of how the user accesses it – through a single web page, or portal. SSL Portal VPNs allow a user to securely access the web from a browser once the user logs into the VPN’s online portal using a specified method of authorization. SSL VPNs come in two types, SSL portal and SSL tunnel. For example, users can be limited to checking email and accessing shared drives rather than having access to the entire network.

Secure Sockets Layer, or SSL VPN, is the second common VPN protocol.Ī big plus for SSL VPNs is that they can allow segmented access for users. Usually meant for use in end-to-end communication between sites, transport mode doesn’t alter the IP header of the outgoing packet. Transport mode on the other hand only encrypts the IP payload and ESP trailer being sent between two sites. Tunnel mode IPsec VPN is typically implemented on a secure gateway, such as on a firewall or router port, which acts as a proxy for the two communicating sites. They also authenticate the receiving site using an authentication header in the packet. IPsec VPNs that work in tunnel mode encrypt an entire outgoing packet, wrapping the old packet in a new, secure one with a new packet header and ESP trailer. IPsec VPNs come in two types: tunnel mode and transport mode. This inability to restrict users to network segments is a common concern with this protocol. IPsec is set at the IP layer, and it is often used to allow secure, remote access to an entire network (rather than just a single device). IPsec VPN is one of two common VPN protocols, or set of standards used to establish a VPN connection. For example, if you visit a client’s site and forget to bring an important file, you can connect to the home network via mobile VPN and grab the file from a shared drive (assuming it’s saved there). Lastly, VPN tunnels are useful when you need to access something on a remote network. Instead of seeing the individual user’s IP address, the third party will only see the IP of the network to which the user is connected via VPN. Since VPN tunnels also obscure user’s IP address, they also make it harder for third parties to track a user’s online activity.

So if you want to check your bank account balance on an unsecure network, such as the free public wifi at a local coffee shop, then a VPN connection will help keep your banking password and account information secure. VPN tunnels encrypt the traffic sent to and from the user, making it all but impossible for would-be attackers to use any data they intercept. The primary benefit of a VPN is enhanced security and privacy.

Two of the most commonly used VPN protocols are SSL and IPsec (more details below). Anyone wishing to track the user’s activity will see the IP address of the user’s VPN-connected network rather than the address of the user’s local network. The user’s IP address is also obscured by VPN. The data sent between the user and the network is encrypted, making it a reliable safety measure when using public wifi and other untrusted networks. VPN also establishes a secure connection. By connecting to the airport’s wifi and then establishing a mobile VPN connection to their office network, they can check their company emails as if they were sitting at a workstation. What is a VPN?Ī Virtual Private Network, or VPN, is exactly what it sounds like – a network with no physical location that is configured to protect a user’s privacy online.Īlso known as VPN tunnels, they allow users to connect to a private network and use its systems even when not directly connected to that network.įor example, business travelers often use VPN at the airport. What is the best one to fit your needs? And why do you even need a VPN?īefore we get to the differences between VPN SSL vs IPSEC, let’s start with the basics. A virtual private networks (VPN) is a popular way for businesses and individuals to enhance their security online.īut VPNs come in many types and protocols.
