It uses different authentication methods, including secret keys, certificates, and unique IDs for passwords and usernames.
There are many free and open-source VPNs on the market today, with each one proclaiming to be the best. If you are looking for an easy-to-use open-source VPN alternative, then you have come to the right spot!
We have compiled a list of the Best OpenVPN Alternatives based on their speed, security, and encryption functions.
8 Best OpenVPN Alternatives for 2022
Libreswan, a popular open-source VPN solution that supports common protocols like IKE and IPsec, is very popular. Red Hat Linux distributions can access the ready-to-use package of Libreswan. It is a top-rated VPN that has been around for 15 years.
IPsec is a carefully designed protocol suite that secures encrypted data being shared between two entities. The IKE, on the other hand, executes secure authentication as well as a dynamic key generation to ensure seamless data flow. The IETF (Internet Engineering Task Force) created and maintains both these standard suite protocols.
Libreswan offers a variety of security features. It also uses opportunistic encryption techniques. This makes it ideal for low- to medium-level encryption needs. It is peer-to-peer and uses repository files. The tarball is used to make it easy to set up.
- Supports NSS crypto library
- Public key-based authentication supported
- IKEv1 & IKEv2 Support
- Pre-shared key-based authentication
- Software implementation free
- It runs on Apple OSX, FreeBSD, and Linux 2.4- to 5. x
- It uses an inbuilt XFRM IPsec stack for Linux
Another open-source SSL VPN client is here: OpenConnect is available for Linux, Windows, and other Linux distributions. OpenConnect, like Libreswan, is also an older VPN and is still in active development.
It was initially designed to replace Cisco’s AnyConnect SSL VPN VPN. It became a standard for many VPNs after much support.
OpenConnect is built upon SSL security protocol. This makes it an attractive alternative. OpenConnect also offers many features that allow you to create your own server, start data encryption, import different server configurations, and much more.
- Based on the SSL security protocol
- Supports data encryption
- Allows you to import server configurations
- Open-source and Free
- Supports connection via HTTP proxy. Also supports libproxy to configure proxy settings automatically.
- Authentication via HTTP forms or SSL certificates
- Automatically detects IPv4/IPv6 addresses and routes.
- Linux users have the best alternative to Cisco and Pulse Secure VPN
Openswan is a popular OpenVPN alternative for Linux users since 2005. It’s an IPsec implementation that supports most extensions (RFC, IETF drafts), IKEv2, NAT Traversal, and X.509 digital certificates.
If you’re running Fedora or Ubuntu, Fedora, Fedora, Fedora, Red Hat, Red Hat, Gentoo, Fedora, or Ubuntu, Openswan may be included in your distribution.
- Open source IPsec VPN package
- Cloudstack VR provides remote access and site-to-site VPN.
SocialVPN (or IP-Over-P2P, as it is also known) is an open-source virtual network that allows end-users to create their own VPNs.
An IPOP virtual network relies on end-to-end tunneling Ethernet or IP via Tincan links. It can also be managed using a control API that allows you to create various VPN overlays.
SocialVPN creates peer-to-peer (P2P), virtual private networks using a social backend such as an XMPP server (JabberNet or Google Chat). This reliable backend can authenticate users securely, keep a list of all parties and establish TLS for X.509 certificate exchanging.
It relies on direct IP connectivity. Multicast support is also provided between two parties, bypassing firewalls, routers, and NATs. It allows IP- and TCP-based applications to communicate seamlessly.
- Free and open source
- IPOP is simple to set up because it works on your existing Internet infrastructure and doesn’t require virtual routers or hardware routers.
- OSN infrastructures are used to allow end-users to create their own networks
- Seamlessly tunnels through firewalls and NATs to create VPN networks using peer-to-peer technology
- Remote access to Linux/Windows via RDP or VNC
- Remote shell access via SSH/SFTP
- Windows file sharing via SMB/CIFS
SoftEther (Software Ethernet VPN Bridge) and VPN Server are compatible with OSX and Solaris as well as Linux and FreeBSD. VPN Bridge is ideal for companies that need to set up site-to-site VPNs. Individual consumers will only require the client and server programs to gain remote access.
SoftEther supports OpenVPN, SSTP, and L2TP protocols. It also features a clone function that allows you to switch between OpenVPN and SoftEther. these are the best OpenVPN alternatives.
SoftEther is able to tunnel through bypass firewalls and NAT firewalls. SoftEther can tunnel over restricted networks that allow only DNS and ICMP packets. Users can use SoftEther’s ‘VPN Over DNS’ or ICMP commands to bypass the firewall.
It works with both IPv4 and IPv6 stacks.
- Free open source SSL VPN client
- Remote access and site-to-site VPN
- User-friendly, powerful multi-protocol open-source VPN software
- OpenVPN’s best VPN alternative; the Clone function available
- It runs on Linux, Windows, and Solaris.
- Support for Microsoft SSTP VPN Windows 7/8/Vista
- This product is ideal for personal and commercial use.
- SSL-VPN Tunneling on HTTPS is used to bypass firewalls.
- Innovative ‘VPN Over DNS’ and ICMP Features
StrongSwan offers excellent encryption standards and IPsec policies for large-scale, complex VPN networks. It is also extremely simple to set up.
You should know that strongSwan is a child of Libreswan, OpenSwan, and FreeS/WAN. The strongSwan server-side is compatible with FreeBSD and Windows, Linux 2.6 and 3.x kernels, Android and macOS, iOS, and Linux 4. x kernels. It utilizes IPsec and IKEv2 protocols to provide high speed and security.
StrongSwan’s flexibility allows for more complex configurations making it ideal for large-scale businesses. Group memberships, which authenticate X.509 attributes certificates, allow access control. It also supports EAP authentication to seamlessly integrate with other networks.
StrongSwan can also traverse NAT firewalls easily.
- Free Open-source OpenVPN alternatives
- Multiplatform IPsec implementation on macOS and Windows open-source VPN clients
- It includes powerful authentication methods using X.509 Public Key Certificates based on group memberships
- Support for tunnel connections and IPv6 IPsec transport has been tested
- Optional: Secure storage of RSA certificates, RSA private keys, and smartcards via PKCS#11 interface. Protection via TPM 2.0
- Fully supports OCSP (Online Certificate Status Protocol), and certificate revocation lists
Tcpcrypt protocol can be used as the best open-source VPN alternative because it does not require any configuration changes, nor do you need to make changes to your network or applications.
It is based on the principle of “opportunistic encryption”, which means that the protocol (unencrypted TCP), will remain cleartext and can only be encrypted when another party attempts to communicate with Tcpcrypt.
Tcpcrypt does not get involved in authentication. Instead, it passes a special “session ID” to the application. This ID token can then be used by that application for secure authentication. In other words, certificates, and passwords are also possible to be used as authentication methods.
It is also vital for the client-side, and it also plays an important role in public key connection initiation, reducing DoS attacks and the load on servers.
Tcpcrypt isn’t really great for large companies but it is ideal for individuals or branches with less sensitive data that need an easy-to-use VPN client to manage all their data.
- Open source SSL VPN client
- It works straight out of the box: No configuration or modifications in applications
- Even if the remote end does not support Tcpcrypt, it will still work seamlessly
- Transport layer communication encryption protocol
- Implementing TCP for seamless and incremental deployment
- FreeBSD, Windows, and Mac OS X are compatible with user-space implementations
- Linux kernel implementation
- RFC 8547, RFC 8548 Experimental Standards
