Many people are looking for encrypted messaging apps to securely communicate with their coworkers, friends, and family. While there are other ways to protect your data, end-to-end encryption has become a standard security feature in both consumer and business messaging apps.
For businesses, encrypted chat is where secure collaboration begins. For many organizations, secure business chat software is detrimental to doing business. Customers expect their data to be safe with organizations they choose to work with, and compromising on data security could mean irreparable damages to business reputation.
That's why encrypted messaging apps are no longer a rarity - not even for consumer-oriented communication. Privacy-conscious businesses go a few steps beyond encryption to ensure secure communication with clients or between their employees.
🗝️ Read on to find out what are the best encrypted messaging apps today, how encryption works, and how else you can ensure highest security standards while texting.
What are encrypted messaging apps?
As their name says, encrypted messaging apps are solutions that support the transmission of encrypted data. Encryption ensures that the only parties that can access the message content are the ones that hold the decryption keys – usually the sender and the receiver.
Therefore, encrypted messaging apps are enforcing one of the most popular and high-standard data protection protocols. Although many people know about encryption through their private messaging providers, it is also one of the most frequently used data protection protocols in business messaging apps.
Moreover, the need for secure collaboration and encrypted messaging apps only increased with the abrupt adoption of hybrid work policies. As businesses moved toward remote work models, they also noticed rising cyber attacks and increased risk of cybersecurity breaches.
More than 50% of IT leaders say that mitigating cybersecurity risks is their priority when it comes to digital transformation. One of the ways to mitigate those risks is to adopt and use encrypted chat apps. Nowadays, such secure business chat software is a norm in digital workplaces around the world.

Best encrypted consumer messaging apps
Encrypted messaging apps became more popular when WhatsApp implemented end-to-end encryption. From then on, we’ve seen multiple apps entering the secure instant messaging market. Without a doubt, WhatsApp remains the most popular consumer messaging app. However, due to sharing data with Facebook, WhatsApp is not considered 100% private and secure.
Here are the best encrypted messaging apps for personal use that adhere to strict data protection standards:
Signal is probably the most famous messaging app for those that want their privacy kept private. With internationally renowned security technologists as its ambassadors, Signal keeps its reputation as one of the best encrypted messaging apps out there.
This Swiss-made encrypted chat app is so secure it doesn’t even require you to enter your email address or phone number to use it. Threema also permanently deletes messages after it is delivered, so there can be no misuse of the data and metadata.
Telegram is an encrypted messaging app that is popular in countries such as Brazil, Russia, and Malaysia. It is popular for offering bug bounty – a $300,000 prize for anybody that detects vulnerabilities in their code. Also, part of Telegram’s business model is refusal to sell customer data, so it is known as one of the safest messaging apps.

How encrypted messaging apps work?
As their name says, encrypted messaging apps use the process of encoding information to prevent anybody viewing the content of them. As data privacy is becoming an increasingly important topic, end-to-end encryption became known as a standard data protection protocol.
However, end-to-end encryption does not equal data privacy and protection. Yes, it does prevent the message from being read if intercepted, but encrypted messaging apps ensure that messages are encrypted only in transit.
What does that mean? This means that the provider of the service can still access the data and read the data – unless they say they don’t. Some encrypted messaging apps explicitly say they don’t store data nor metadata on their servers, or sell them to third parties.

Moreover, encrypted messaging apps cannot guarantee data protection if endpoints are compromised. This is why there are many new technologies and initiatives aimed at increasing endpoint security.
In any case, encrypted messaging apps are becoming the standard when it comes to safe communication. Communication industry is the leader when it comes to using encryption, but 60% of employees say their organizations transfer confidential data to the cloud whether or not it is encrypted.
However, messaging apps meant for businesses need additional safety measures and protocols to ensure security of their – and their customers’ – data.
Is your business chat software secure enough? Look for these features.
End-to-end encryption is an important security feature of messaging apps, but it’s surely not the only one. If they’re privacy-conscious or operate in highly-regulated industries - like government & defense, healthcare, or education - businesses will want to fortify the security of their communications with these features:
Certificates like ISO 27001 are internationally recognized standards for information security management systems. Such certificates prove that the encrypted messaging apps are audited on annual basis by independent third-party auditors.
Secure push notifications
Push notifications can be tricky and reveal confidential information. To many organizations out there, it’s important to have an ID-only push notifications feature in addition to end-to-end encryption of their messaging apps.
Data privacy regulations compliance
Depending on the region or industry, businesses might need to comply with data privacy regulations such as GDPR or HIPAA. Encrypted messaging apps partly comply with such regulations merely because of data encryption. However, there are several other customization options that the app admins need to configure to be fully compliant.
Access control and device management
Role-based permissions based on Single Sign-On, Multi-Factor Authentication, and other methods are often a required feature for secure messaging apps. Even thought they are encrypted, messaging apps could still be accessed by someone pretending to be someone else. Role-based permissions are crucial for avoiding such security breaches.
Using open source technology is considered to be a great way to enhance overall security. Namely, open source software is upgraded according to its community members’ feedback on a frequent basis - also meaning stronger security.
Organizations that want maximum communication security deploy encrypted messaging apps on-premise. This ensures complete control over any data that gets exchanged between communicating parties.
For organizations like governmental agencies, on-premise deployment is often a requirement, just as it is for other businesses in highly regulated industries.
Why are encrypted messaging apps the best choice for security-conscious businesses
Encrypted chat is a prerequisite for secure collaboration. Although encryption does not equal data protection, it is one of the most important features when it comes to messaging security.
These are just some of the reasons to get an encrypted messaging app – for private use or for your business.
1. Unlock the power of team communication and collaboration
With a secure encrypted chat app, business leaders can unlock the power of effective team communication and collaboration.

2. Evolving trust with customers
Did you know that in 2019, 52% of Americans opted out of using products or services because of privacy concerns? This speaks volumes about the necessity of encrypted messaging apps. Encryption is the minimum you simply can’t afford to neglect!
When a cybersecurity breach happens, businesses are deemed as less trustworthy. Why should you care? Because data privacy and security is becoming a reason for consumers to purchase a product. According to research, 54% of companies are using encryption to protect their customers’ personal information.
3. Diminishing costs
In industries such as healthcare or financial services, there are laws and regulations that businesses must adhere to when it comes to customers’ data privacy. Not complying with those regulations can be costly – for example, there were $63 million worth of fines issued in the first year of GDPR policy in the EU.
Moreover, cybersecurity breaches that can happen due to insecure communication between employees can also turn out to be costly. This IBM report says that the average cost of a data breach in the US is $3.8 million.
🗝️ All in all, encrypted messaging apps can save businesses a lot of time and money. However, encryption is not the only safety protocol that businesses need to employ. Check out this list of messaging apps’ security features you should look for to ensure data security.
