Pros and cons
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.
LastPass US LP
Pros
- Covers Windows, macOS and Linux from a single account
- Authenticator support through TOTP codes sits in the same vault, listed under totp
- A free plan is available, and the paid tier can be tried for 30
Cons
- Support runs on help centre, community and email only, with live chat and a phone line not listed
- Free storage stops at 1, below the 5 seen across the brands compared
- LastPass Families: 6 Premium accounts means shared family logins stop at that many Premium accounts
Who each suits
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.
LastPass US LP
Who it suits
- People moving between a Windows desktop, a Mac laptop and a phone who want one vault
- Households sharing logins through LastPass Families, which covers LastPass Families: 6 Premium accounts
- Users who keep authenticator codes next to their passwords
Who should look elsewhere
- Total Password, which has no free plan, so you pay from the first day
- Apple Inc., whose apps run on iOS, iPadOS and macOS only, for buyers who stay inside that ecosystem
- ESET Brasil, which lists Windows, Windows Server and macOS, for teams that also cover Windows servers

Questions about each
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.
LastPass US LP
Is there a free version of LastPass?+
Yes. A free plan is available and includes 1 of storage. It covers the same Windows, macOS and Linux range as the paid tiers, so you can start at no cost and move up later if the limits get in the way.
What does the free trial cover?+
The paid tier can be tried for 30. That window sits alongside the free plan, so you can compare what a paid vault adds before committing. Trial accounts use the same AES-256 encryption with PBKDF2 hashing and SHA-256 salting as every other tier.
