What Is Email Encryption?
Email encryption is one of the newest protection means. It saves your emails from unauthorized access by encoding the content inside them. It guarantees the confidentiality and privacy of the information you share.
Online criminals, hackers, or even service providers might try to mess with your personal data. Encryption prevents them from easily reading or intercepting it. This strategy is a must in our world full of dangers. As Stephane Nappo, Global Chief Information Security Officer at Groupe SEB said,
“It takes 20 years to build a reputation and a few minutes of cyber-incident to ruin it.”
So, what the encryption process is all about? It uses complex mathematical algorithms to convert the original text of an email into a cipher or code. After this transformation, no one would be able to read it without the appropriate decryption key. Typically only one intended recipient holds this key.
Below, we gathered some encryption techniques you might use. We recommend you get familiar with those and choose the most suitable one.
End-to-End Encryption
Emails are most vulnerable in transit. The main point of this method is to safeguard your content throughout its entire journey. When you send the message your device encrypts it immediately. It remains that way until the email reaches the intended recipient.
Even if someone manages to grab your letter in the middle of a transmission, they can’t understand it. E2EE will give you a sense of confidence and safety.
Public Key Infrastructure
PKI uses a pair of cryptographic keys – private and public. They work in tandem to ensure the integrity of your digital messages. It can help you establish a framework for trust in online communication.
The public key is an open component. Basically, anyone can access it. On the other hand, a private key is a closely guarded counterpart. Only one person knows it.
SSL/TLS Protocols
These protocols are a layer of defense between the sender’s and receiver’s email servers. They encrypt the communication channel. They safeguard your info when a third party attempts to intercept and alter it.
Zero-Knowledge Architecture
When you apply this technique the service provider can’t access the encryption keys or the content of your emails. You can provide all your users with confidentiality. Zero-knowledge encryption safeguards your personal data against both – external and internal threats.
Authentication Mechanisms
Encrypted email services often incorporate strong authentication mechanisms. You can implement multi-factor authentication and secure login procedures for example. People will have to provide multiple forms of identification to enter the encrypted account. You can include passwords or biometrics for that purpose.
Open Source Protocols
Open-source protocols are known for their transparency. Security experts and developers review the codes. They can detect any loopholes and fix the problems.
It’s a collaborative approach to security. This can demonstrate your commitment to openness and accountability. People you communicate with know that knowledgeable and diverse community evaluated the protocols.
Why Email Encryption Is A Must?
Email is a key communication channel for many people and organizations. Encryption allows you to protect any sensitive information that your messages contain. Which benefits it can offer you?
Confidentiality Protection
This strategy actively preserves the confidentiality of your email content. It makes it unreadable to unauthorized parties. With the help of encryption, you can shield sensitive information, like
- Personal data;
- Financial details;
- Proprietary information;
- Trade secrets, etc.
Prevention of Data Breaches
Data breaches involving emails can have some severe consequences, like
- Financial loss;
- Reputational damage;
- Regulatory penalties.
Email encryption can help you prevent them. Even if someone manages to “steal” your messages, they won’t know how to decipher them. You can lower the chance of illicit access to your information with this technique. It protects both you and your clients from possible harm.
Compliance with Regulations
Multiple laws and compliance norms demand the protection of sensitive data. It is particularly important for sectors that handle finance, healthcare, and legal documentation. Email encryption complies with data protection laws such as:
- General Data Protection Regulation;
- Health Insurance Portability and Accountability Act;
- Payment Card Industry Data Security Standard, and others.
When you adhere to these regulations, you’ll avoid any penalties. It also shows your commitment to maintaining privacy and security.
Defense from Phishing Attacks
Online criminals often attempt to trick people. They make them reveal confidential info or click on malicious links. If you encrypt emails, they become less susceptible to manipulation or alteration. You can create a digital signature that verifies the sender’s identity. Also, the encoded content guarantees that the email retains its original form.
Security of Intellectual Assets
You can’t overstate the significance of intellectual property. It is one of the fundamental possessions of any business. Email encryption can help you shield it. It protects confidential documents, product designs, research results, and any other information you share via email. So, no rivals, hackers, or untrustworthy workers will be able to take advantage of it.
