Security and cloud communication: why WebRTC is the most secure protocol

Digitalisation has transformed many areas of business, especially in communications. For example, most companies now use cloud communication systems. By operating over the Internet, they can gain a number of advantages, such as the ability to serve their customers from anywhere and to incorporate other channels beyond traditional voice telephone calls.

It is true, however, that while the digitisation of our communications offers great opportunities, it also means facing new challenges, such as offering our customers a guarantee that no fraud or data leakage will occur. This can only be achieved by choosing a solution that uses a secure protocol: WebRTC.

This technology has been proclaimed as the most secure among its competitors, mainly compared to the SIP protocol, as it has a series of particularities that make it the most secure technology to communicate with our customers. Do you want to know what they are? We will tell you about them today!

No downloads or installations required

As we already know, WebRTC is an open source protocol developed by Google that allows communication and transmission of data and files in real time. Precisely because it is an open source protocol, it can be used on any device and anywhere if we have an Internet connection, as we only need access to a browser to manage our communications.

However, we must be cautious and ensure that our cloud communication solution is precisely “in the cloud”. This means that it truly uses the WebRTC protocol and that it is accessible through any browser, without the need for downloads or any changes. 

It is important to bear this in mind, as some solutions claim to be “fully cloud-based”, but the truth is that they require us to download an executable or softphone to operate, thus breaking with the definition of a fully cloud-based solution. What’s more, this leaves the door open to cybercriminals, who have a very easy access route to try to steal information.

Typically, one of the easiest ways for cybercriminals to intercept sensitive data is through malware or malicious software. The most common way for such software to spread is usually by downloading certain programs and files in which it has been embedded, even if they come from a company or website that we trust. 

If we do not have to take this step, we will be protecting ourselves against a possible theft of confidential information, both ours and our clients’.

Constant updates

Another way for cybercriminals to intercept data is through outdated systems. So when we talk about communications security, we must also be mindful of the need to update our systems. 

Depending on the protocol used, these updates will be carried out automatically or we will have to be aware that we will have to carry them out from time to time. 

In the case of WebRTC, the browsers themselves are responsible for including security patches. In other words, they are the ones who carry out the updates automatically, correcting possible errors and vulnerabilities that may appear. Unlike other protocols such as SIP, by not having to perform this action manually, we avoid our systems becoming obsolete and security breaches.

It relies on many technologies

More than a protocol, we could speak of WebRTC as a “super protocol“. In order to deploy all its functionalities and for the process to be secure, it must necessarily include other protocols, such as HTTPS, DTSL (Datagram Transport Layer Security) and SRTP (Secure Real-Time Transport Protocol).

You have probably noticed that when you browse a website, a padlock appears next to its URL stating: “The connection is secure”. This is because the browser has verified that the page complies with all standards and that you can share data with confidence. With WebRTC, it is not possible to establish unsecured connections, which reinforces the security guarantee of our cloud-based solution.

Encrypted conversations

Finally, related to the above, another way in which WebRTC increases the security of communications is by ensuring that voice, video and chat conversations are always encrypted thanks to the SRTP protocol. By this term, we refer to a way of encoding information so that if someone intercepts it, it is protected and cannot read it correctly.

However, it is true that in recent years, due to the increase in interactions through other communication channels such as instant messaging, fraud and data leaks have also increased considerably, especially when it comes to the relationship between customers and companies. 

The reason is that, although these applications offer the guarantee that communications are encrypted, it is the companies themselves who make use of them, and many businesses still continue to use a version of them that does not offer any kind of security to the user that their data is truly being used by a company.

For example, as we know, WhatsApp has two versions for businesses: WhatsApp Business and WhatsApp API. Among other differences, the former does not require Facebook (Meta) to approve the business account and verify that it is indeed a company. This means that anyone can impersonate a business and mislead users.

So, if we want to increase customer confidence in our company, the best thing to do is to use the WhatsApp API. But we must bear in mind that this version is designed to connect to other tools and work within them, so the ideal is to find a cloud provider that allows us to integrate all these channels.
