What is Cisco Clientless Ssl Vpn?

The CISCO Clientless SSL VPN assures safe and easy access to a diverse set of web resources. Here do keep in mind that SSL refers to ‘Secure Sockets Layer’, while VPN on the other hand is abbreviated for ‘Virtual Private Network’.

To name some – Internal websites (all HTTP and HTTPS), Windows file shares, Web applications, Email servers including IMAP, POP3, Microsoft Outlook Web Access.

It ensures that all users can safely access their corporate network from any remote location. As it’s a highlighting characteristic of the product, it provides limited but valuable access to a corporate network and proves to be a great asset.

Its main function is to aid the user to achieve secure browser-based access to corporate resources.

Any system that can reach HTTP (Hypertext Transfer Protocol Internet) sites can help the user access both web-enabled and legacy applications.

Thus, it needs a Hypertext Transfer Protocol format over an SSL connection to provide access to the user. There is no need for a VPN client to be installed on the computer of the user.

Thus, no additional client is needed to provide separate access to internal resources.

What is AnyConnect?

AnyConnect is a tool that extends the corporate network’s perimeter to remote endpoints and enables continuous integration of web filtering services. These web filtering services are offered by web security appliances.

Anyconnect provides VPN access through a Secure Sockets Layer (SSL) while also offering extremely strong security using its various built-in modules. 

For AnyConnect VPN’s installation, we require the usage of a Clientless VPN.

ASA firewall works as an AnyConnect WebVPN Server that assigns a pre-programmed IP Address to remote users which then enables them to establish a secure connection with their organization’s corporate network.

This means that remote user has the privilege to access the AnyConnect to Join the ASA and after joining they will get a unique IP Address from this VPN database. This means that they would be getting full access to the respective network.

The entire mechanism uses IP Protocols and Applications which then function across the SSL VPN Tunnel. It is a complete error-free process.

In short, Anyconnect is an extremely secure and reliable tool that allows remote access to a designated set of resources to its users. It is highly Intelligent, dependable, and comes with an integrated always-on connectivity feature.

In addition, it also has a wide set of compatible devices, from pc to even android and ios. 

Main Differences Between Cisco Clientless Ssl Vpn and Anyconnect

  2. CISCO SSL Clientless VPN won’t require the installation of any VPN client on the user’s system. It uses commonly used web browsers (like Chrome and Firefox) for the same. Alternatively, AnyConnect requires download of a VPN Client to build a guarded network between the two parties.
  3. CISCO SSL Clientless VPN is a secure portal to access internal resources of any corporate network. Users can simply authenticate the firewall by entering the ASA Address and unlocking access to the corresponding web portal. 
  4. CISCO SSL Clientless VPN provides its users limited access to internal applications like windows file shares, email servers, etc whereas Any connect does not.
  5. The SSL VPN is referring to a separate portal that allows users to access a company’s internal resources through web-based java plugins, While AnyConnect VPN itself is an entire SSL VPN client.


Concluding through the aforementioned facts, it is evident that when using Clientless SSL VPN, the users don’t have to download a VPN Client on their computer to get access to any corporate network.

The downloading and installing of a VPN Client on the user’s computer is the last and the most crucial step for a user to gain full access to a corporate network that is using AnyConnect. 

This difference can be attributed to the program’s inherent architecture, as before the step of downloading the VPN Client on the user’s system, using both CISCO Clientless SSL VPN and AnyConnect requires the use of a simple web browser like Google Chrome or  Mozilla Firefox.
