The Best Practices to Enhance Your Chatbot Security

Chatbots are communication tools that help a business or company connect with its customers, find their problems, and recommend the best possible solution. They are usually software solutions that combine machine learning and artificial intelligence to have a conversation in human form. Communicating with these chatbots can be done either by voice or in written form.

Chatbots help a company carry out a lot of functions, including scheduling appointments, carrying out marketing campaigns, and serving as customer support. Nevertheless, there are often security risks associated with these chatbots, and this has led to many data loss and leakages. In this article, you will learn some of these chatbot security risks and the best practices to mitigate them.

Security Risks Associated with Chatbots

Understanding chatbot security includes knowing the security risks associated with them, and they are mainly classified into vulnerabilities and threats.


Vulnerabilities come from the inside, and they are the faults of chatbot systems, which provide access to malicious elements and hackers. The major causes of security vulnerabilities in any chatbot include user errors, incorrect programming/coding, and weak security systems. Furthermore, some of the vulnerabilities a chatbot may have are backdoor access, hosting platform issues, lack of HTTP protocol, unencrypted communication, etc.


Threats are the external classification of security risks associated with chatbots, as they mainly come from the outside. They are usually one-time events, which either make the company lose revenue or less to the exposure of information in their database. An excellent example of chatbot security threats is phishing.

Phishing attacks are one of the most common security challenges users face, and this is also prevalent when discussing chatbot security. In chatbots, a phishing attack can happen in many ways, including the chatbot asking users to click a link through their email accounts. When this chatbot lures a user to click such a link, it injects malicious code, which can lead to loss of data and resources.

Phishing is not the only type of security threat, as there are many others, such as distributed denial of service (DDoS) attacks, malware attacks, and ransomware. For a user, it is often recommended they use security solutions such as LayerX to guarantee protection from data loss.

Best Practices to Enhance Your Chatbot Security

The following are some of the best practices which can help to enhance your chatbot security:

Self-destructive Messages

This is one of the best practices that can make a chatbot secure and can contribute to effectively preventing data leakages. So, after communication between a chatbot and a user/customer, the messages and every sensitive data are erased forever. In other words, the chatbot does not store any interaction with users but destroys them after a particular time elapses. An excellent example of a self-destructive messaging system is Snapchat, where a chat automatically disappears after 24 hours.

Chatbot Should Meet Security Standards

If a company is trying to introduce a chatbot for their business, one of the security practices that will benefit them in the long term is checking the security standards of the bot. The company can do this by looking at the security certifications of the chatbot, and it should include ISO 27001 and SOC2 certifications. This certification is published by the International Organization of Standardization (ISO) in collaboration with the International Electrotechnical Commission (IEC). It is a voluntary certification, which indicates that the chatbot technology has the necessary resources to protect a company’s and users’ data.

On the other hand, the SOC2 certification was developed by the American Institute of CPAs, and it provides a sort of guarantee that the chatbot is safe and secure. This verification is based on five principles, and they include confidentiality, privacy, processing integrity, security, and availability.

Use of Secure Protocols Such as SSL/TLS

Deploying secure protocols such as SSL (Secure Socket Layer) and TLS (Transport Layer Security) is one of the best practices that helps secure communication between a chatbot and its users. Installing these protocols doesn’t bring an end to all the security risks associated with chatbots, but it significantly minimizes them. Organizations looking to get their SSL certificates can do so by submitting a Certificate Signing Request (CSR) to a certificate authority (CA).

Regular VAPT Tests

One of the security measures that can protect a company from the embarrassment of having a compromised chatbot is conducting regular VAPT tests. These tests help to prevent hackers from getting access to the chatbot system by identifying vulnerabilities on time. Moreover, the vulnerability assessment helps to identify the security weak points of the bot and provide necessary solutions to such. It is often recommended that VAPT tests should be outsourced to a third party to get results and eliminate biases.

Two Factor Authentication

Two-factor authentication is an age-long security practice and is incredibly effective in verifying the identity of the user and singling out malicious elements. When introduced in a chatbot, users will be required to verify their identity to gain access to any communication with the chatbot. To confirm their identity, they will be sent a verification code to their phone number, and they will get access if they input the correct code.

Data Anonymization

Data anonymization can save and provide an extra layer of security for any company that owns a chatbot for their business. Previously, there have been new cases of chatbots like ChatGPT leaking users’ information. To prevent such a thing from happening, a user can decide to use LayerX’s ChatGPT DLP for maximum security. On the other hand, any company using a chatbot should introduce data anonymization to ensure that customers/users cannot be identified from a data set, assuming there’s a leak.


Chatbots are becoming an integral part of many businesses as they serve a vital role in communicating with customers and providing solutions to their queries. Nevertheless, there are security risks associated with these chatbots, and they are classified into vulnerabilities and threats. Some of the vulnerabilities that a chatbot might have include a lack of HTTP protocol, hosting platform issues, and back door access.

On the other hand, phishing, ransomware, and distributed denial of service (DDoS) attacks are examples of chatbot security threats. To mitigate these threats, an organization can employ security measures such as implementing secure protocols, data anonymization, regular VAPT tests, and two-factor authentication.
