VPN is a family of technologies. Site-to-site, client-to-site, SSL VPN and IPsec solve different problems. Choosing the wrong approach can create security gaps and operational overhead.
Site-to-Site VPN
Connects two or more offices through an encrypted tunnel over the internet, usually using IPsec. It is the traditional solution for multi-location enterprise networks.
Client-to-Site (Remote Access VPN)
Provides secure internal-network access for employees at home or traveling. Common approaches include SSL VPN, which can offer browser-based access and simple setup, and an IPsec client with a desktop agent for greater control.
Which one suits you?
- Connecting multiple offices → Site-to-Site IPsec
- Traveling employees → SSL VPN for ease of use
- Access with stronger security requirements → IPsec client
- A modern Zero Trust approach → SASE / ZTNA without a traditional VPN
A newer alternative: ZTNA
Zero Trust Network Access (ZTNA) is gradually replacing traditional VPN access in modern architectures. Users receive access only to authorized applications, rather than the entire internal network, improving both security and usability.
