How Secure Is Encryption
Encryption scrambles the contents of a message so that only the sender and recipient can open the message. But how reliable is encryption? The fact is, encryption is incredibly powerful. You might be wondering whether the security of encryption comes down to computing power alone. While older, outdated methods of encryption can be broken by a brute-force attack given a certain level of resources and time, todays highest levels of encryption will continue to be secure in the future. Given current computing power, there is no feasible way that a malicious actor can access the contents of a message encrypted with AES 256 bit or an equivalent encryption standard.
Secure The Machine You Use Email On
Arguably the most important aspect of using email securely is making sure the device you use is secure. While important, it is rarely considered a risk. Yet it is the most significant risk. You could take all the precautions in the world and use the most secure email provider on the planet but if you have a keylogger on your device, all your efforts are for naught.
Regardless of the device type, the precautions you take are the same. Perform a virus scan regularly with a freshly updated, good quality virus scanner. If you use Windows, use Malwarebytes and perform a malware scan. The two scans look for different things so its important to perform both. Apple, Android and Windows all need antivirus scans to regardless of the device you use, keep them secure.
Keep your browser and operating system up to date. Many viruses, Trojans and malware target weaknesses or vulnerabilities within a browser or OS. Regular updates are released to plug these weaknesses so you should always keep your programs up to date. This is true for every electronic device you might use.
Whats The Best Way To Send And Receive Encrypted Email
At its core, encrypted email describes a process where email messages are encoded so they cant be read by people who arent part of the conversation. Given that email can easily be read if there is no encryption in place, its really important to have encryption for your individual and enterprise communications so you can protect your email account. There are many ways of protecting you email messages over the internet. Not all these methods are equally secure. Some methods actually leave emails vulnerable to attack. This vulnerability is a result of either weak encryption standards or leaving the message unencrypted at points along its journey. This blog will look at the methods for email encryption as well as how to build strong email encryption protocols for the enterprise.
How does email encryption work?
When email was first created, there were limited encryption standards in places to secure email messages and limited ways to send encrypted email. Messages were transmitted in plain text. However, over the years as criminals showed how easily this standard enabled the theft of information, technologist implemented security protocols to ensure messages were protected as they went from the sender to the receiver. Today, the main protocols for email encryption are:
- Transport Layer Security
- End-to-end encryption
These standards are used widely and work in very different ways that will be explained below

Features And Cost Of S/mime To Encrypt Emails In Outlook
Once the initial setup has been completed and certificates have been properly shared, email encryption using S/Mime in Outlook is relatively user-friendly. However, if you are considering encryption options for your business email, we recommend this option only for cases where your recipient explicitly asks for such encryption. That is only likely the case if your business or professional practice serves large enterprise clients or government agencies. Companies working with small businesses or independent individuals are not likely to be able to use S/Mime, as these parties typically utilize free webmail accounts on platforms like Gmail and Yahoo, and may lack both the resources and knowledge necessary to purchase and set up this encryption option.
If S/Mime is used, it is important to note that users cannot access encrypted emails outside of the Outlook application. Moreover, recipients may be unable to forward encrypted emails to other users. And S/Mime is not compatible with G-Suite email accounts using GSSMO. Such G-Suite email accounts must instead use IMAP.
The cost of S/Mime varies greatly. In 2019, the certificate prices of Microsofts recommended CAs ranged from $39 to $369 annually. This is a recurring fee that has to be renewed each year, or every 2-3 years if multiple years are paid ahead of time. Furthermore, this is the cost of a single certificate for a specific user. Thus, each user within an organization must obtain a unique certificate.

So What Other Options Are There
If native end-to-end encryption and the highest possible level of privacy is what you’re after, your best bet is to look outside of Gmail and toward a standalone email app called ProtonMail. ProtonMail is among the best privacy and security apps on Android and for good reason: It makes privacy a top priority in ways no form of standard Gmail encryption can match.
First, ProtonMail uses an open-source method of end-to-end encryption that ensures no one beyond your intended recipient not even the folks at ProtonMail can ever see your messages. Beyond that, the app doesn’t require you to provide any personal information to use it, and the company maintains no records of IP addresses or anything else that could associate your identity with your account. Its servers are also hosted in Switzerland in a “bunker 1000 meters under the Swiss alps,” no less which has its own apparent set of security benefits.
So here’s how it works: When you sign up, ProtonMail gives you a custom email address at its domain. You can then use that address to send secure messages within the ProtonMail Android app, iOS app, or web interface. Whenever you email someone else with a ProtonMail address, encryption is automatic. If you email someone who isn’t using ProtonMail, you can choose to send the message unencrypted just like any regular ol’ email or you can click a button to create a password and a hint that the recipient will need in order to decrypt and read your message.

How To Encrypt Email
- 6 minute read
Email encryption is the process of disguising the content of your email messages to protect them from being read by unwanted parties. Sensitive information such as social security numbers, passwords, login credentials and bank account numbers are vulnerable when sent via email.
When encrypting emails, its important to encrypt all of them, not just the ones with sensitive information. If only some of your emails are encrypted, it is a red flag for a hacker and could make your inbox even less secure. They will only have to hack into a few emails rather than sift through hundreds to find data they can use. We explain how to encrypt emails on multiple providers and summarize our tips in an infographic.

How To Encrypt Email Attachments
There are a few different ways to encrypt emails, starting from the broad network-level protection called TLS . Most major email providers have TLS encryption baked in, which protects your emails in transit or within the providers servers. However, TLS doesnt provide complete security: emails outside the server or individual attachments arent protected.
The next level of protection is end-to-end encryption. This security protects your emails from point-to-point, so no matter where those emails end up, theyre still secure. When you send an attachment that is encrypted end-to-end, the file is converted into a format that is unreadable without a digital key. When the recipient clicks on the attachment, the encryption server checks to make sure youve given that person permission to access it. The intended recipient can then save and open the fileprovided they can decrypt it. Anyone trying to intercept the file along the way, however, will be stuck with the unreadable data, instead of a photo or other sensitive document.
One of the most effective ways to enable end-to-end protection is with the Trusted Data Format , created by Virtru CTO Will Ackerly. TDF is a powerful way to protect and control access to highly-sensitive intelligence information, because it can safely encrypt any type of file.
Choose A Secure Email Provider That Has Strong E2ee Encryption
If you want to send emails and email attachments that are protected using reliable encryption such as PGP, the best option is to get an email account with a secure email provider that has a focus on privacy and security.
