Things to Consider When Choosing a Email Encryption Tool

Strong Filtering Accuracy

Since it is plausible for emails to spread malware even by opening the message, an email security solution must have good filtering accuracy to protect inboxes against cyber threats and prevent false positives.

Antiphishing Protection

Most email threats are disguised as legitimate emails from reputable sources rather than spam. These emails are sent to customers to persuade them to reveal personal information. Because specific anti-phishing capabilities are sold separately, check sure the solution you're purchasing includes anti-phishing protection.

Robust Encrypted Email Archiving

SMBs frequently lose access to critical email messages. Regulatory compliance rules may also bind them, dictating how long they must store all email correspondence. As a result, email storage might take up a lot of space. As a result, seek archiving solutions that incorporate encryption to help keep data secure and solutions that provide customers the flexibility to choose their own retention time.

Conclusion

Email encryption is vital for an enterprise to carry out its marketing plans as intended without any blocks in the middle. We hope you captured a gist of what email encryption tools are and which to rely on.

FAQs

What is Email Encryption?

Email encryption encrypts or conceals the content of emails to prevent potentially sensitive information from being read by someone other than the intended receivers. Authentication is frequently included in email encryption.

Hackers use email to target victims and steal personal information such as names, addresses, and login credentials, which they then use to perpetrate crimes such as identity theft and fraud. Email encryption solutions encrypt email messages using public-key cryptography and digital signature techniques to prevent unwanted activity. This procedure provides email security by ensuring that only the intended recipient can open the message.

What Are Email Encryption Tools?

When sending sensitive material over email, encryption is required. Email encryption is a method of protecting messages from being read by an unauthorized or unintended recipient. The originally sent communication is scrambled and converted into an unintelligible or undecipherable format.

Email encryption tools are software applications that allow businesses to handle the encryption and authentication of emails simply.

When Should You Consider Using Email Encryption Tools?

Regardless of its size, any company should use email encryption solutions in its services. Because cyberattacks are becoming more common and sophisticated by the day, businesses must rely on a reliable security solution.

What is Public Key Infrastructure?

In most cases, email encryption is based on a Public Key Infrastructure (PKI), which comprises of a private key and a public key. The public key is used by those who want to encrypt emails, while the receiver uses the private key to decrypt the messages into a readable format.

Anyone can encrypt email using a public key in the PKI model, but only a unique private key can decrypt each encrypted communication.

What is Transport Layer Security (TLS)?

TLS (Transport Layer Security) is a cryptographic technology that follows the Secure Sockets Layer (SSL) (SSL). It allows messages to be securely transmitted across a computer network and is widely used for email and other communication forms such as instant messaging and Voice over Internet Protocol (VoIP).

TLS strives to protect data integrity and privacy when communicating between computer applications. It consists of the TLS record and TLS handshake protocols and runs in the application layer.
