End-to-end encryption for electronic mail and different cloud providers is rising in reputation. Given that electronic mail is among the prime two cyberattack vectors, that is no shock.
According to Verizon’s annual 2022 Data Breach Investigations Report, mail servers accounted for 28% of all affected {hardware}, and 35% of ransomware actions concerned electronic mail. The EU Agency for Cybersecurity’s 2022 report famous that ransomware accounts for 10 terabytes of information stolen monthly with 60% of firms more likely to have paid a ransom. A 2021 Gartner research, up to date for 2022, reported that about 40% of ransomware assaults begin with electronic mail.
To handle these challenges, Google, Microsoft and Proton, whose Proton Mail service was a first-mover in safe electronic mail, each moved to broaden end-to-end encryption choices.

Google and Microsoft’s new electronic mail encryption
In a weblog publish final month, Google introduced a beta of client-side encryption providers for Gmail on the net. Google Workspace Enterprise Plus, Education Plus and Education Standard prospects could apply for the beta till Jan. 20, 2023.
Noting that it encrypts all knowledge at relaxation and in transit in Google Workspace between its amenities, Google stated client-side encryption “helps strengthen the confidentiality of your data while helping to address a broad range of data sovereignty and compliance needs.”
According to Google, client-side encryption is already obtainable for Google Drive, Google Docs, Sheets, Google Slides, Google Meet and Google Calendar.
Google defined that so as to add client-side encryption to any message, customers want solely click on the lock icon and choose the choice for added encryption. Composing and including attachments goes per regular operation.
Microsoft, which final up to date its message encryption in 2019, introduced final April that Windows 11 would obtain safety updates in new releases, reportedly to deal with each phishing and malware threats.
If so, Microsoft will probably incorporate end-to-end encryption as properly, because it presently makes use of Transport Layer Security encryption for Office 365 Message Encryption. While the corporate explains that this service lets customers encrypt and rights-protect messages certain for inside and exterior recipients utilizing Office 365, non-Office 365 electronic mail purposes, and web-based electronic mail providers comparable to Gmail.com and Outlook.com, it doesn’t stop phishing or malware assaults as successfully as E2EE.

Proton’s new purposes
Google’s announcement adopted that of Proton, an encrypted cloud storage platform launched in 2013 in Geneva, Switzerland by CEO Andy Yen. The firm final fall expanded its encryption choices with a concentrate on cell gadgets, together with safe cloud storage and a safe calendar function, with apps for each iOS and Android gadgets.
Proton Drive
Proton Drive, which turned obtainable in late September as a free encrypted cloud service and was launched on iOS and Android in December, lets customers securely add, save, and share information to and from their telephone.
According to the corporate, Proton Drive:
- Encrypts any uploaded file on the person’s machine earlier than it’s saved on Proton servers.
- Encrypts metadata comparable to names of information and folders, file extensions, file sizes and thumbnails.
- Includes file expiration and passwords for viewing, permitting for safe sharing with non-Proton customers.
Proton stated that because the launch of Proton Drive final September — with over half 1,000,000 customers taking part within the beta — it has seen, on common, a million information uploaded per day, about half of that are pictures.
For particular person customers, Proton presents a free tier of its encrypted drive with 1GB of cloud storage, plus two further ranges of service for a worth: Drive Plus with 200GB storage is $4.99/month or $47.88 per yr, and Proton Unlimited with 500GB for $11.99/month or $119.88 per yr (Figure A).

The firm additionally launched pricing tiers for enterprise customers:
| Feature | Mail Essentials | Proton Business |
|---|---|---|
| Price | $7.50/month per person | $11.70/month per person |
| Storage | 15 GB per person | 500 GB per person |
| Custom electronic mail domains | 3 | 10 (plus limitless aliases) |
| VPN | 1 free | 10 free |
There can be a custom-pricing tier that features a devoted supervisor and limitless storage.

Proton Calendar
Proton launched the Calendar iPhone app in December after having launched it for Android and the online in April 2022. According to Proton, the brand new app:
- Integrates with Proton Mail, letting customers handle invites or add occasions to the calendar with out leaving the inbox
- Besides end-to-end encryption, makes use of elliptic curve cryptography (ECC Curve25519) to safe knowledge and schedules
- Invites are blind encrypted so Proton doesn’t know their identification. This considerably enhances the anonymity of the members.
- Is open supply, as is the online app, and independently audited with code obtainable for inspection (Figure B).

Proton’s lengthy sport: An encrypted ecosystem
A spokesperson stated the calendar represents the bigger technique of making a fully-fledged privateness ecosystem.
“We’re seeing huge demand for encrypted services — that’s why over 70 million people have signed up to private services like Proton, and it proves that surveillance capital isn’t the only business model that works in tech,” stated the spokesperson.
The firm, which additionally presents Proton VPN, which competes with the likes of AtlasVPN, Nord, Express and HIDEme, has a two-fold rationale for creating Proton Calendar, in response to the spokesperson: First, since a calendar is a repository of delicate time and placement person knowledge, it constitutes a menace goal; second, it’s a part of Proton’s bigger safe cloud providers technique.
“As far as privacy is concerned, Proton is today the most complete ecosystem,” Yen stated. “There is nothing from either Google or Apple that is as comprehensive, as their encrypted offerings are limited (for example, Google’s email encryption is only available for business users).”
He asserted {that a} key distinction with opponents is enterprise mannequin and enterprise practices.
“Proton, as a Swiss company, is not subject to the surveillance laws and practices of the U.S., and unlike Google and Apple, who both have robust advertising businesses, Proton’s only business is privacy,” he stated. “We therefore have no conflict of interest when it comes to user privacy.”
