With the rise in cyberattacks and data breaches, cybersecurity measures are increasingly being adopted to secure areas where personally identifiable information (PII) may be vulnerable, such as email accounts and their messages. Along with security filters that intercept malicious messages, email encryption is now a commonly used option to enhance an enterprise’s defences. In this blog, we’ll answer some questions often asked regarding this innovative solution.

What is end-to-end email encryption?

End-to-end encryption is a communication system where only the users communicating can read messages being sent and received. When using this form of encryption, if a sender transmits an email, only their intended recipient will be able to view or interact with the message, ensuring its privacy during transit.

How does email encryption help companies avoid data breaches?

Data breaches occur when personal data is exposed to the public or unauthorised individuals. Personal information is often sent via email and if read by the wrong recipient or a malicious actor, such an event constitutes a breach. Fortunately, if the email has been encrypted, neither party can read the message mitigating the chance of any leaked data.

Do I only need to encrypt sensitive emails?

Experts warn that the practice of only encrypting sensitive content can attract malicious actors to the most confidential material in emails and email accounts. Instead, they advise encrypting all emails to obfuscate any material that must remain private from potential attackers.

Will encryption software also cover email attachments?

A wide range of email encryption products are available, and each solution will deliver different levels of protection and functionality. Always select a product that will encrypt your email attachments as well as the body copy of a message. Remember that attachments often include the most confidential information, for example contracts and databases packed with PII or invoices and financial agreements with payment details.

Is complexity a sign of encryption software effectiveness?

While encryption software that is complicated to use may seem more secure, it can make companies vulnerable to a cyberattack. If staff find software too tricky to use, they may avoid adopting it or use it ineffectively. Such actions can quickly lead to a data breach.

How can I be sure that encryption software is effective?

When investing in an email encryption solution, you’ll want to be sure you’re getting the security you deserve for the price you pay. The best way to ensure you can trust security software is to pick a product that has been approved by the National Cyber Security Centre (NCSC). Additionally, select a service provider that will offer you a free trial so you can test it out for yourself and assess if it suits the way your company operates and the volume of data you send and store.
