The Importance of SSL Tunnel VPN for Secure Online Communication

5 min read

SSL VPNs rely on widely used web clients and do not require installing or maintaining dedicated client software. As such, they are often more user-friendly than traditional IPSec solutions.

However, using a browser as the gateway exposes users to malware attacks via an internet connection. Luckily, SSL VPN solutions are designed to prevent this from happening by utilizing split tunnel functionality.


SSL and VPNs create secure tunnels that encrypt your data, keeping it safe from unauthorized people who might spy on your communication. Hackers need to know the exact keys – and there are 2256 combinations possible – to break the encryption. That’s why it takes the most powerful computers in the world years to crack this type of security.

Another benefit of SSL Tunnel VPN is that it’s based on the TLS protocols built into most modern web browsers, meaning there’s no need to install and maintain specific client software. It also makes SSL tunnel VPNs easy to set up, allowing remote access through an encrypted tunnel that users can access from any device with a browser.

Additionally, many SSL tunnel VPNs offer advanced security features that aren’t available in IPSec-based solutions. For example, many SSL-based products enable authentication to verify that a user is who they claim to be. It helps prevent unauthorized users from infecting the enterprise with malware.

In addition, SSL tunnel VPNs allow administrators to implement exact access rules that build tunnels to specific applications rather than the entire network, making it easier to control precisely what employees have access to. It can be conducive for companies that employ contractors or other out-of-office workers who don’t need full access to the enterprise network but might require more granular access to specific internal applications.


An SSL tunnel VPN offers a reliable way to connect remote employees to enterprise networks. It creates a secure path to the company’s internal systems, files, and applications. It also protects Internet sessions outside the network and enterprise firewalls.

This type of VPN connection is based on SSL or TLS protocols, which are widely deployed. It encrypts all the data transmitted between the client and the VPN server, making it impossible to read or intercept. It is why SSL VPN is a popular choice for secure remote access.

The best part is that it requires no specialized client software. SSL VPN is compatible with all modern web browsers, meaning employees can access it from their mobile devices or home computers without installing a separate application. It saves IT, staff, time, and money.

Furthermore, SSL VPN uses a standardized protocol. It makes it less susceptible to interoperability issues than IPSec, a set of Internet standards that continues to suffer from problems with compatibility between products.

In addition, an SSL VPN can provide additional protection by using split tunnel functionality to route traffic back to the home site via the local Internet connection and not through the corporate network. It helps to avoid bandwidth bottlenecks.


The main benefit of SSL tunnel VPN is that it uses TLS protocol technology to secure a user’s connection to a private network, even when using an internet-connected device on the go. Employees can connect to company applications and systems from their home or office computers, no matter where they’re located. It provides flexibility and convenience for remote workers. It allows an organization to expand its workforce without worrying about how its devices will connect or be able to access the internet.

In addition, SSL tunnel VPN solutions are typically easy to maintain and offer a high level of compatibility. They rely on TLS protocols commonly used by popular web browsers, such as Chrome and Firefox. It prevents organizations from installing and updating client software on all user devices, saving IT time and money.

Most SSL VPN solutions will also include authentication features that can prevent unauthorized users from connecting to the network and grant access privileges to users only when they have been validated as they say they are. These security measures help to eliminate the risk of information leaks and minimize the impact of data breaches. However, a delicate balance between convenience and security needs to be achieved for these solutions to truly protect the integrity of communication.


SSL VPN solutions are prevalent among businesses and users alike due to their high level of security and ease of use. They are lovely to organizations with a distributed workforce, as they do not require installing specific client software on each device. The technology works with a wide range of platforms and requires only a modern web browser to connect.

With the rise of work-from-home orders, many employees must access their corporate network remotely from various devices. Unlike traditional VPN clients that require downloading and installing proprietary software on each endpoint, SSL VPNs rely on standard TLS protocols supported by most internet-accessible browsers, such as Chrome and Firefox. It allows remote users to connect with minimal fuss and frees up IT support time.

The centralized control offered by SSL VPNs also helps to reduce data breaches. By allowing administrators to establish very fine-grained access rules, they can ensure that the most sensitive company information is never exposed outside the network ecosystem. While this can still leave traces of sensitive information on a user’s computer — such as temporary files, cookies, and spooler directories — this is far less of a threat than if the same sensitive data were left in unsecured locations like a USB stick or email attachment.
