Transport Layer Security (TLS) is the protocol that is used to provide security for data that are shared over the internet. Every day there are millions of data shared around the globe through the internet. As a result, the security of those data became an important topic. Consequently, TLS was developed. It encrypts the data to be shared on the internet so that no third party can intercept or eavesdrop except for intended recipients. So, here we will discuss the Pros and Cons of TLS (Transport Layer Security).

Internet Engineering Taskforce (IETF) created TLS as a protocol to be strictly followed. In the present context, most web browsers and applications around the world use TLS.

TLS generally uses a private key and a public key to share data. When data is transferred those keys are generated after the data encryption. The private keys and public keys are to be matched for the sender to decrypt the data. Even if a third party receives the data they would not be able to view content as they do not possess the key. This makes data sharing through the internet more secure.

In summary, TLS is the backbone for data security throughout the globe. Here are some of the Pros and Cons of TLS (Transport Layer Security):

Pros of TLS:

1. Data safety:

Due to the encryption and decryption facilities provided by the TLS, data shared through the internet is safe. You do not have to worry about your data or information getting eavesdropped on or misused.

2. Hides complexity:

Generating private and public keys along with encryption and decryption is a very long task. There is a load of complex computation to be done. Since the TLS layer lies beneath the application layer, the complexity is hidden and users do not even know the computation behind it.


3. Interoperability of TLS:

TLS works almost in all web browsers, operating systems, and web servers including various applications. This helps to be assured that their data are safe and they will not be misused in any way.

Cons of TLS

1. Limited support for the new version:

The new TLS version 1.3 is supported by very few platforms. Due to its complexity providers are finding it hard to implement.

2. Vulnerable to attacks:

There are previous cases of attack in TLS 1.0 as mainly man-in–middle attacks (MiM). This increases the concern for data integrity and authentication.

3. More latency compared to other security protocols:

TLS has higher latency compared to other types of security protocols. This is caused by many things due to the nature of TLS


In conclusion, we can say that the security of data transfer through the internet is very important. And TLS is doing a great job for maintain a high level of security. Also, we knew about the Pros and Cons of TLS (Transport Layer Security). For this main reason, TLS is currently used widely all around the world. Most web browsers and service providers use TLS. The TLS is also improving throughout the years. It is now being integrated into the 5G network. The new version of TLS is released, such as TLS 1.3 which is more secure than the previous version.

With help of TLS, we can all experience a safer browsing experience. And hopefully, future versions will be better than the current ones.
