How to Ensure Encryption of Internal and External Online Communication



Table of Content:




As businesses continue to move their operations online, the need for secure and encrypted communication tools has never been greater. With the rise of cybercrime, it is more important than ever to invest in protecting your internal and external online communication. 

You can ensure your online communication is secure in several ways. This article examines some of the best methods for encrypting your online communication. We will also provide tips on ensuring your communication remains confidential. 



Internal Communications 


Encryption at rest: At-rest encryption encrypts data when not in use. This type of encryption is usually used to protect data stored on devices such as hard drives or laptops. When information is encrypted at rest, it is much more difficult for hackers to access it, even if they can physically steal the device. 


There are many ways to encrypt data at rest, but one of the most common methods is using full-disk encryption. This type of encryption encrypts all the data on a device, including the operating system and any applications installed. Full-disk encryption is often used on laptops and other portable devices that may be susceptible to theft. 


Another standard method of encrypting data at rest is to use file-level encryption. This type of encryption encrypts individual files rather than the entire hard drive. This is less resource intensive and allows you to encrypt only the files that are important to you. 


Encryption in transit: This is when you encrypt data that is being transported from one device to another.  

There are many reasons why you should encrypt data in transit. For example, you should protect sensitive information from being intercepted by someone not authorized to see it. Encryption can also prevent data from being modified in transit, ensuring that it arrives at its destination in its original form. 


There are several different ways to encrypt data in transit. The most common method is Transport Layer Security (TLS), a protocol that uses encryption to protect data as it is being transmitted over the Internet. TLS is used by most websites and is what allows you to browse the web without fear of your information being stolen. 



Secure Network Protocols 


In computing, an encrypted network protocol is a network protocol that uses security mechanisms to protect communications from being intercepted during transit or read by unauthorized parties. There are a variety of encrypted network protocols in use today, each with its strengths and weaknesses. 


Some of the most popular encrypted network protocols include SSL/TLS, SSH, and IPsec. Each of these protocols uses different algorithms and security measures, so it's important to choose the best one for your needs. 

Encrypted network protocols are an essential part of keeping communications safe and secure. If you want to protect your data, consider using one of these protocols. 



External Communications 


VPNs for encryption: A VPN, or Virtual Private Network, is a great way to encrypt your internet traffic and protect your privacy. When you use a VPN, all your internet traffic will be routed through an encrypted tunnel, making it much harder for anyone to spy on your online activity. 


Email Encryption: Email encryption is the step-by-step process of transforming readable email messages into an unreadable format. This is done to protect the information contained in the email from being stolen and read by anyone other than the intended recipient. Email encryption is an important security measure that can be used to protect sensitive information, such as business secrets or personal correspondence. 


There are various email encryption methods, but Pretty Good Privacy (PGP) is the most common. PGP uses a unique combination of public-key and symmetric-key cryptography to encrypt and decrypt messages. To use PGP, both the sender and the recipient must have a PGP key pair. The sender must use the recipient's public key when encrypting the message, and the recipient will use their private key to decrypt it. 


In addition to using individual email encryption protocols, you can also use an email encryption solution. For example, Sealit has email encryption add-ins for Gmail and Outlook that allow you to easily implement encryption in your daily usage.  





HTTP is the most widely used protocol on the web, and HTTPS is the most secure version of HTTP. HTTPS is simply HTTP that has been encrypted using Transport Layer Security (TLS) or Secure Sockets Layer (SSL). TLS and SSL are encryption protocols that help protect web traffic from being intercepted by attackers. 


HTTPS is not just for e-commerce websites or websites that handle sensitive data. Any website can benefit from HTTPS encryption, including news, blogs, and even personal websites. Even if your website doesn't take sensitive data, you should still consider using HTTPS to help protect your visitors' privacy. 





It is crucial to ensure that your internal and external online communication is encrypted to protect your information from being intercepted and accessed by unauthorized individuals. There are several ways to encrypt your communication and choosing the method that best suits your needs is essential.
