With the onset of the Covid-19 pandemic, companies have started to have many of their employees work remotely as a precaution. This is where the SSL VPN Client comes into play. It allows your employees to connect to the company network and their company computers from home or a different location. For this, private virtual networks are preferred instead of physical connections.

This connection is made through a tunnel and is encrypted. Therefore, it has a solid structure against external infiltration and viewing of your data. It also has some features such as keeping the IP address of the connecting party secret. The basis of the system is formed by the AH and ESP component protocols.

What are ESP and AH?
Encapsulating Security Payload is the first of the basic components of VPN. In order to provide secure communication within SSL VPN Client ,

Data protection,
Identity verification,
Provides encryption services.
By default, it does not protect the packet header, but it can encrypt the entire packet. The Authentication Header is used to verify the protocol data in the next level with the IP header. It is in the form of nested encapsulation and has the capacity to work with ESP.

Data integrity is ensured using checksum, and the secret shared key is used for source verification. The most commonly used protocols today are SSL VPN and IPSec VPN systems.

What is SSL VPN?
SSL VPN Client provides remote connection to the web server via SSL encryption and a web browser. This provides access to network services and other resources on the connected site.

However, for this, the user must use the ID given to him/her. After a successful login, the system is started to be used. After a certain period of time, it is possible to reconnect even if the VPN is disabled.

What is IPSec VPN?
IPSec offers security options such as encryption, compression and authentication in private network connections. It protects the IP packet. In order to achieve this, it encapsulates, encrypts and adds a new IP header and sends it to the other end of the connection.

When tunnel mode is activated, ESP and AH codes are added to the front and back of the IP packet. Encapsulation is thus completed. Both the user and the system can communicate securely.

What Advantages Does SSL VPN Provide?
If you have to have some of your staff work remotely, SSL VPN setup offers you the solution you are looking for. In this way, you can both continue your work and be sure of security. The conveniences provided by the system are as follows;

The remotely connected computer operates as if it were on the same network.
Network architecture can be set up quickly.
No additional hardware is required. Encrypted communication is provided between regions, branches and different institutions.
It offers a centrally manageable network structure.
The system administrator can set permissions for access and apply restrictions. Therefore, it also ensures that additional security measures are taken. For example, it is possible to restrict access to the system outside of working hours. Our company allows you to manage your business more efficiently and securely with SSL VPN Client solutions.
