Optimizing performance with Zero Trust Access
In the modern world, remote access to corporate resources is becoming increasingly important for the efficient operation of a business. However, existing traditional methods, such as VPN, often face performance problems, making it difficult for employees and increases security risks. The new Zero Trust Access solution offers an innovative approach to providing secure and efficient remote access.
A look at performance problems from different angles and solutions
Let's look at the main problems that organizations face when using traditional remote access methods, such as VPN. Then we'll discuss how the new Zero Trust Access solution helps overcome these challenges and optimize performance.
VPN performance problems include:
- Loss of connection due to packet loss or blocking. For example, a user is connected to a VPN and suddenly loses connection to the corporate network due to packet loss or blocking on the router. This may happen due to an unstable Internet connection or due to restrictions imposed by your ISP or firewall.
- Disconnection due to problems with device or network settings. For example, the user enters the correct credentials VPN but cannot connect due to incompatible network settings on his device or due to conflicts with other programs or services that use the network.
- Delays due to long data transfer through a remote server. If the user is located at a considerable distance from the VPN server, and data is transmitted through cable networks, this leads to delays in the transfer of information. For example, if the server is located in one country, and the user – in another on another continent, this may cause delays due to long response times.
Challenges with traditional access methods refer to the shortcomings and limitations that organizations face when using old and outdated methods to provide remote access to their corporate resources:
- Delays and vulnerabilities with RDP due to its configuration and public access. Remote Desktop Protocol (RDP) allows remote access to computers and servers. However, it may be subject to attacks due to its public availability. If not configured correctly, RDP can become vulnerable to hacking or abuse. Delays may occur due to network congestion or slow connection between remote user and server.
- Insufficient performance and difficulties with SD-WAN due to data routing features. SD-WAN — It is a software-defined broadband networking technology that manages data traffic across multiple networks. However, its complex configuration and data routing increasingly lead to insufficient performance and difficulties in ensuring the optimal route for data transmission. This causes latency and performance losses when accessing corporate resources over SD-WAN.
One solution to all problems: Zero Trust Access
Solution to the above problems – in using Zero Trust Access. This is a modern security concept that differs from traditional approaches to protecting networks. It is based on the principle of continuous authentication and authorization for every session and access request, even within an organization's network.
Zero Trust Access implements:
- Use encrypted tunnels for direct access to applications without intermediaries. The product uses encrypted tunnels that provide direct and secure access to enterprise applications without the need to go through central servers or intermediaries. This provides faster and more efficient access for users, minimizing latency and increasing data security.
- Use a decoupled architecture to prevent performance issues. A decoupled architecture separates data and control into different planes. This allows you to manage traffic more efficiently and avoid performance issues such as overloading servers or network nodes.
- Point topology to eliminate delays in data transmission. In a point topology, data is sent directly from the user device to the target applications, bypassing unnecessary intermediate nodes or servers. This allows you to reduce delays in data transfer and provide faster access to corporate resources.
Zero Trust Access is an innovative solution for ensuring secure and efficient remote access. By leveraging advanced technologies and architectural approaches, it helps optimize productivity and ensure security for employees anywhere, anytime.
Private VPN server: an effective addition to modern solutions
Private VPN server can be integrated or complement the Zero Trust Access concept. It can be used as one of many mechanisms to provide secure access to corporate resources.
Although a private VPN server is not a core component of the Zero Trust Access concept, it can be configured as an additional layer of authentication and encryption for users who have already completed the Zero Trust authentication process. This allows you to strengthen the level of security, providing additional guarantees in the event of suspicious activity or unauthorized access.
