How To Protect Security: Trusted, Secure And Hybrid VPN
The combination of all the elements makes it possible to distinguish the three levels of security adopted for VPNs.

When the VPN is created on a virtual private network considered safe, such as the one provided by the internet access operator, it is defined as Trusted.
The high level of security also allows, in some cases, to do without encrypted tunneling.
Using such a network also brings performance benefits.
In a Trusted VPN, in fact, the Customer’s information travels only on the operator’s network and not on the Internet so I can take advantage of better performance in terms of latency, the number of hops, and packet loss. The operator’s network also guarantees continuity and quality of service (QoS). This is not possible if you use a VPN service that uses the normal internet network.
Secure VPNs allow you to access the Internet safely, thanks to the protection offered by tunneling and VPN protocols.
This type of solution is beneficial for those who use smart working and remote access, even though unsecured connections such as public WiFi access.
As we have already seen, thanks to encryption, if a hacker intercepted the data, he would still be unable to read it because he does not have the right key.
Some technologies allow you to take advantage of a combination of Trusted and Secure VPN’s advantages to guarantee additional levels of security and control over network paths. In this case, we are talking about Hybrid VPN.
Business continuity and VPN: the topology
The VPN must guarantee high performance and continuity of service.
To ensure that the VPN guarantees business continuity, it is also necessary to consider the topology, that is, the way in which the VPN network is built between the offices to make it more “robust” and resistant to failures.
There are two most popular VPN topologies: star and mesh.
Hub & Spoke (star)
Star networks are the most common. This topology includes a hub or switch – also called the star center – which acts as a central point for the transmission of information. Each host is connected to the center point, like spokes in a bicycle wheel.
Data within a star network passes through the hub before arriving at its destination. In addition, the hub manages and controls all the network functions.
This type of network reduces the impact of a failure on the transmission line by independently connecting each host to the hub. Each host can communicate with all others and the hub.
The failure of a transmission line connecting a host to the hub will result in the isolation of the single host without affecting the others.
Any to any (knitted)
The mesh or mesh topology requires that each node is directly connected with all the others with dedicated branches, as in the meshes of a network.
The main advantage of this network topology is its robustness in the face of connection failures between nodes. The number of branches used determines the reliability level of the network.
In a fully meshed network, given any node, there is always at least one path that allows it to be connected to another node in the network.
