What is TLS ?
Transport Layer Security (TLS) is a type of protocol
which makes sure that the communication between the clients and the
server is safeguarded. Generally all the websites that needs to feature
HTTPS certificate needs to have a TLS certificate too. Despite keeping
the communication private, there are several flaws in TLS that
ultimately leads to breaches. Likewise there are some reasons on why TLS
should be used.
Why was TLS introduced ?
In modern world of technology, business and organizations consider more about security. The data that is shared with the internet, tends to have more chances of being attacked from hackers and unauthorized access. For this purpose security protocols such as TLS is introduced.

In this article, I will be concentrating on 5 Advantages and Disadvantages of TLS | Weaknesses & Benefits of TLS. From this post you will know the pros and cons of using TLS certificate.
Let's get started,
Advantages of TLS
1. Data Integrity
The type of certificate that is exchanged between nodes is specified by the TLS. Therefore, TLS ensures that no any data that is being transmitted gets lost on its way. It will reach its destination safely.
2. Trustworthy
Whenever a site is secured by the TLS, it can be considered to be reliable. This is especially true for retailers and commercial websites. When the customers notice the green lock mark, they can be confident enough to conduct transactions.
3. Security
TLS is considered to be secure solution to transfer data on the web. Unlike in SSL where it uses Keyed Message Authentication, TLS uses a cryptographic method known as the HMAC (Key-Mashing Authentication Code). This method ensures that record cannot be tampered whiles its on transfer over the internet.
4. Malware Prevention
Some intruders can come up with malwares that tamper the communication between the web browser and the client. Through this intruders can gather confidential informations such as the credit card details and user login credentials. Using TLS these kinds of attacks are prevented. Thus, informations are not leaked over the network.
5. Granular Control
TLS provides more advanced and reactive alert system. Whenever there are problems during sessions and documents, users are alerted immediately. Hence, users can be benefited from Granular Control here.
Disadvantages of TLS
1. High Latency
Comparing to most of other secure encryption methods TLS provides higher latency. Whenever TLS is used, additional latency will be added to the site's traffic.
2. MiM Attacks
Al though TLS is generally considered to be secure, some versions of TLS is still vulnerable to Man in the Middle Attacks. Besides this, other forms of cyber attacks such as SLOTH, POODLE and DROWN are also found to be susceptible.
3. Platform Support
Even though latest versions of TLS support many of the platforms, there are some versions such as TLS 1.3 that is only able to support few of the platforms. Popular Operating system provider Microsoft is facing difficulty with the implementation process.
4. Implementation Cost
Implementing a TLS certificate isn't free, there are some costs involved. However due to the competition in the TLS industry, the cost of TLS certificate has been drastically reduced. The amount that needs to be paid depends upon the number of domains and sub domains. Apart from that it may also depend upon identity verification.
5. Network Complexity
Complexity in the network architecture is another major disadvantages of the TLS certificate. In this case automatically the network topology can also become complex leading to more fail overs. In order for handling this there should be proper network expert hired.
