In the world of networking, protecting data and ensuring secure communication between branches and employees has become something that we can not overlook. This is where VPNs come into play, each serving specific needs. Let us get acquainted with the types in detail:

Site-to-Site VPN:

This type is used to connect two or more networks in different geographical locations. For example, if you have a head office in Riyadh and other branches in Dammam and Jeddah, a Site-to-Site VPN connects them online in an encrypted and secure way. It has two main types of this VPN:

• Intranet VPN: Used when all branches belong to the same company, it means that you connect your internal network more widely.
• Extranet VPN: If you partner with a second company or supplier, you use this type to connect your network to theirs in a secure way.

Purpose: Connects two or more geographically separated networks securely.

Remote Access VPN:

This type is intended for employees who work remotely or need to connect to the company's network from outside the office. Whether you're at home or at a hotel, you can connect to your corporate network just like you're in the office. Remote Access VPN guarantees you an encrypted and reliable connection, which is an essential feature for employees who need flexibility to work remotely.

All you need is a browser that supports HTTPS, and you have a secure and encrypted connection to the desired applications. This type is ideal if there are employees using external devices that are not owned by the company.



MPLS VPN

MPLS VPN (Multiprotocol Label Switching VPN) uses a proprietary protocol that provides fast and secure communication between the different locations of the company over a completely private network provided by telecommunications companies. Well

Advantages of GRE for VPNs:

Flexibility: GRE can be used to create VPN tunnels between various types of networks, including networks with different protocols or addressing schemes.
Customization:offers flexibility in configuring the tunnel, allowing for options like multiple tunnels or different encryption methods.
Widely Supported: supported on most routers and network devices, making it a readily available tunneling option


IPsec VPN:

Internet Protocol Security (IPsec)
to secure communication between two networks. EThe type is commonly used in Site-to-Site or Remote Access. It features strong data encryption and provides high protection against threats.
