Proton AG

Pros and cons
Enpass
Pros
- A free plan exists and holds Up to 25 items in 1 vault, so a small vault costs nothing to keep.
- Entry price $1.99 undercuts Total Password, which lists €9.99 at entry.
- Vault data stays in the user's own cloud, so nothing readable rests on Enpass servers.
Cons
- Enpass is not open source, so outside researchers cannot read the code themselves.
- Support runs on help centre, community and email, with no phone line or live chat in that list.
- The free plan stops at Up to 25 items in 1 vault, so a larger vault needs a paid plan.
Proton AG
Pros
- No-logs claims are audited rather than asserted: Securitum's audit (Securitum, 2026) sits behind a No activity logs policy.
- Free limits come with no caps on data or speed, no ads and no time limit.
- 10 simultaneous devices, above the ranked VPN median of 8.
Cons
- Support runs on email, chat and help centre, and there is no phone line among them.
- The free plan limits put you on a single device at medium speed with randomly selected countries, so constant use points at a paid plan.
- End-to-end encryption is marketed for Proton for Business, while the consumer plan encrypts only the connection from your device to Proton's servers.
Who each suits
Enpass
Who it suits
- People who want a password manager to try with no payment, since the free plan holds Up to 25 items in 1 vault.
- Users who already back up to their own cloud and want the vault stored there rather than on a vendor's servers.
- Households sharing a subscription, since the family plan adds family management on annual billing.
Who should look elsewhere
- People who want passwords kept inside the operating system, where Apple Inc. covers iOS, iPadOS and macOS.
- Buyers set on a different vendor at a higher entry price, such as Total Password at €9.99.
- Anyone who needs a vault larger than Up to 25 items in 1 vault without paying.
Proton AG
Who it suits
- Readers who want a VPN, a passkey vault and encrypted storage under a single account instead of separate subscriptions.
- Families sharing storage, since Pass Family covers several users and Pass Plus seats through a single admin panel.
- Teams buying under a business audience (business) who need GDPR, HIPAA and ISO 27001 certifications on file.
Who should look elsewhere
- Anyone needing more devices on a single account: Proton covers 10, while ESET Brasil plans run 3 to 25 devices.
- Readers choosing purely on server spread: AVG lists from 100 countries, a base close to Proton's from 140.
- Readers who want a different audit trail to compare: Session Technology Foundation lists Quarkslab 2021 against Proton's Securitum, 2026.

Questions about each
Enpass
How much does Enpass cost to start?+
Enpass lists plans from $1.99 at the entry point. The family plan is billed annually and adds family management for a small group of people. On entry price the brand ranks 4 of 36 brands compared here, so the starting figure sits toward the cheap end.
Is there a free version of Enpass?+
Yes, Enpass has a free plan, and it holds Up to 25 items in 1 vault. That cap suits a short list of logins rather than a full household vault, and it means trying the apps costs nothing. Anyone who outgrows the limit moves to a paid plan.
Proton AG
What does Proton VPN cost, and how long are the commitments?+
The longest plan runs 24 months, the service is listed on a free model, and paid plans carry a 30-day money-back window. Across the ranked VPN field, monthly pricing has a median of €7.02 and long-term pricing a median of €3.97, which frames any quote you see.
Is there a free plan, and what are its limits?+
Yes. The free plan has no caps on data or speed, no ads and no time limit. It runs on a single device, reaches servers in a randomly selected group of countries and delivers medium speed, so the paid tier, which covers 10 devices, is the practical step for constant use.
