Personal Experience with Site-to-Site VPN
Site-to-site virtual private network (VPN) connections have become an essential tool for businesses in today’s digital world. I have personally utilized site-to-site VPNs to connect multiple networks, such as my company’s headquarters and branch offices, securely and efficiently.
Key Points
1. Increased Network Connectivity
Site-to-site VPNs allow for seamless and secure connectivity between different networks, enabling efficient sharing of information and resources.
2. Enhanced Security and Privacy
By encrypting and securing data transmitted between networks, site-to-site VPNs ensure that sensitive information remains protected from potential threats.
3. Cost-Effective Alternative
Using site-to-site VPNs as an alternative to traditional private MPLS circuits can significantly reduce costs while maintaining the same level of network connectivity.
4. Suitable for Remote Work and eLearning
In today’s remote work and eLearning environment, site-to-site VPNs have proven to be invaluable in securely connecting remote offices, branches, and employees.
5. AWS Site-to-Site VPN
AWS provides a fully-managed service called AWS Site-to-Site VPN, which allows secure connections between your data center or branch office and your AWS resources using IPSec tunnels.
6. Limitations of Site-to-Site VPN
Site-to-site VPNs have limitations in terms of scalability, as each connected site requires a unique connection, resulting in exponential growth in the number of VPNs for fully-connected networks.
7. Types of Site-to-Site VPN
There are two main types of site-to-site VPN: Intranet based VPN, which connects multiple offices of the same company, and Extranet based VPN, which allows companies to connect to the offices of other companies.

What are the disadvantages of site-to-site VPN
Site-to-site VPN disadvantages
A site-to-site VPN does not provide additional security to the networks that it connects; the secure tunnel it establishes just protects data in transit between two or more networks.
What is the difference between AWS client and site-to-site VPN
AWS VPN is comprised of two services: AWS Site-to-Site VPN and AWS Client VPN. AWS Site-to-Site VPN enables you to securely connect your on-premises network or branch office site to your Amazon Virtual Private Cloud (Amazon VPC). AWS Client VPN enables you to securely connect users to AWS or on-premises networks.
What are the benefits of site to site VPN in AWS
AWS Site-to-Site VPN offers customizable tunnel options including inside tunnel IP address, pre-shared key, and Border Gateway Protocol Autonomous System Number (BGP ASN). In this way, you can set up multiple secure VPN tunnels to increase the bandwidth for your applications or for resiliency in case of a down time.
Is AWS site to site VPN secure
Each Site-to-Site VPN connection consists of two encrypted IPsec VPN tunnels that link AWS and your network. Traffic in each tunnel can be encrypted with AES128 or AES256 and use Diffie-Hellman groups for key exchange, providing Perfect Forward Secrecy. AWS authenticates with SHA1 or SHA2 hashing functions.
Is there a downside to using a VPN
One reason why you may not want to use a VPN is because it could slow down your internet connection speed significantly. There are several factors that affect your internet speeds when using a VPN, including the fact that a VPN encrypts your data and routes it through different servers, which slows down the process.
Can I just leave my VPN on all the time
VPN can be kept on all the time
To sum it up, keeping your VPN on all the time is not only perfectly safe but actually recommended. It can keep your online identity anonymous, protect you from attacks associated with unsecured public Wi-Fi networks and help you bypass various artificial restrictions.
When should a VPN not be used
When should you turn off your VPN While we recommend to keep your VPN on as much as possible, there may be cases when you actually need it off. This includes accessing local content or devices. For instance, you may need to access streaming services that are unavailable in countries you're virtually connected to.
