With the public internet becoming an integral part of our daily lives and corporate networks, the challenge of safeguarding sensitive data transmitted over unsecured cyberspace has emerged. Understand the differences, principles, and Common use cases of different VPNs, including VPN for Teams, VPN as a Service, and VPN corporate solutions.

You might be familiar with using a VPN for streaming services and other personal activities, but did you know that specific virtual private networks are designed explicitly for businesses like yours?

Operating a business in the digital era without a VPN is simply not secure, and the repercussions of falling victim to a cyberattack can take years to recover from.

This article will delve into different types of VPNs, including VPNs for teams, VPNs as a service, and VPN corporate solutions. We will explore the dissimilarities between these VPN variants, examine their typical use cases, and introduce a new advancement in corporate VPNs.

Understanding Remote Access VPN

Remote Access VPN, also known as Virtual Private Network, is a technology that establishes a secure and encrypted connection between employees and the remote business LAN or cloud. It enables employees working from various remote locations to connect to the company's network as if physically in the office.

The Importance of Remote Access VPN in the Era of Remote Work

In the current era of remote work, where employees can work from home or other off-site locations, Remote Access VPNs have become essential for businesses. Many employees may use their personal devices to connect to the company's network, which can pose security risks if not adequately protected. Additionally, using unsecured Wi-Fi networks at home or public places like airports adds further vulnerability to data transmission.

Ensuring Secure Remote Connectivity with Remote Access VPN

Implementing a Remote Access VPN allows businesses to enable their teams to work remotely without compromising security. The Remote Access VPN works through a client application installed on the host computer, which communicates with a VPN gateway. The VPN client handles user authentication, ensuring only authorized users gain access to the network. The VPN gateway then encrypts and sends the data across a public connection, securing it from potential eavesdropping or unauthorized access.

Enhancing Security with IP Whitelisting

To provide an additional layer of security, access to the company's network from a static IP address can be restricted through IP whitelisting. This ensures that sensitive applications and data remain cloaked from the public, adding extra protection.

Benefits of Remote Access VPN

  • Facilitating Remote Work:

    Remote Access VPN enables employees to work from various locations, promoting flexibility and productivity.

  • Data Security:

    By encrypting data transmission, Remote Access VPN ensures that sensitive information remains protected from cyber threats.

  • Secure Wi-Fi Usage:

    Employees can securely connect to the company's network even using unsecured Wi-Fi networks.

  • Access Control:

    User authentication and IP whitelisting enable businesses to control network access and ensure that only authorized individuals can connect.

A remote access VPN creates a private and encrypted virtual network for the company, allowing employees to access resources securely and work remotely without compromising data security. It has become an indispensable tool for businesses embracing remote work and ensuring a safe and efficient work environment for their teams. As the world adapts to remote work trends, Remote Access VPNs will remain crucial in safeguarding corporate networks and data from potential threats.

Understanding Site-to-Site VPN

A Site-to-Site VPN is a type of Virtual Private Network that establishes an encrypted tunnel between two or more private corporate networks. It enables seamless communication and resource sharing between different branches of an organization, allowing employees to access resources from various locations securely.

The Need for Site-to-Site VPN

When sensitive data needs to be transmitted between different branches or locations of an organization, sending it directly over the public Internet can pose significant security risks. A Site-to-Site VPN provides a secure and encrypted connection, safeguarding data from threats and unauthorized access.

How Site-to-Site VPN Works?

Site-to-Site VPNs utilize routers/firewalls with VPN functionality or dedicated VPN gateways to encrypt packets before transmitting them over the network. This encryption ensures that communication remains unreadable to potential threat actors. Unlike other VPN types, site-to-site VPNs do not require client applications on hosts, making it a cost-effective alternative to private MPLS circuits.

Typical Use Cases

A Site-to-Site VPN is well-suited for various use cases, including:

Interconnecting Branch Offices: It establishes a wide-area network (WAN) that connects branch office networks with the central corporate network, allowing seamless access to shared resources.

Accessing In-House Resources: Site-to-Site VPNs enable employees to access shared securely, in-house resources such as data, email servers, or proprietary software.

Sharing Geographically Distributed Resources: It provides a secure way to share geographically distributed resources as if they were in the same building.

Comparing Site-to-Site VPN and Remote Access VPN: Understanding the Differences

Virtual Private Network (VPN) technology is crucial in securing network communications and enabling remote access to resources. Site-to-Site VPNs and Remote Access VPNs are two prominent types that cater to different needs within an organization.

Here's the comparison between Site-to-Site VPN and Remote Access VPN:


  Site-to-Site VPN Remote Access VPN
Use case Site-to-Site VPN combines separate office networks into a shared LAN ecosystem. Remote Access VPN connects individual users to private internal networks.
Data flow In Site-to-Site VPN, data moves through the office's gateway and leaves fully encrypted. In Remote Access VPN, each user creates their own VPN tunnel when connecting, and data leaving the device is encrypted.
Tunneling Site-to-Site VPN allows multiple users to share a single VPN tunnel. Remote Access VPN creates an individual VPN tunnel for each user connecting to the network.
Users Site-to-Site VPN suits office employees connecting to other branch offices or headquarters. Remote Access VPN is ideal for employees working from home or other locations outside the office.
Setup Site-to-Site VPN must be set up on all premises. Each end device connecting to it automatically gains access to the internal network with no additional configuration needed. Remote Access VPN requires specific software or configurations on each client's device to connect with the HQ server and obtain network access. The HQ server setup must also accept incoming VPN traffic.


Wrapping Up

Both remote-access VPNs and site-to-site VPNs offer various advantages and can be used together in a complementary manner. You can have remote workers accessing office resources through a remote access VPN while simultaneously connecting multiple office networks using site-to-site VPN tunnels.

When it comes to prioritizing security, a remote access VPN may be the preferable choice as it ensures data protection during transmission. In scenarios where a team is distributed across multiple locations, implementing a B2B remote access solution like PureDome can safeguard sensitive information and mitigate risks associated with endpoint threats.
