- Covers 5 devices on Windows, macOS and Android

Who each suits
Mysterium VPN
Who it suits
- Households and small teams that want 15 device slots on one account, well above the 7 median.
- Readers who want a browser extension and desktop and mobile apps on the same plan, since Android, iOS and macOS covers all of them.
- People who put a written no logs pledge and open source code above a low monthly price.
Who should look elsewhere
- Apple Inc., whose own privacy subscription is $0.99 a month, if a light browsing tool is enough.
- Sinew Software Systems at $1.99 a month, when stored passwords are the real problem.
- ESET Brasil, which covers 3 to 25 on its antivirus plans, when you want endpoint protection instead of a tunnel.
Surfshark One (Antivirus)
Who it suits
- Readers who already pay for a VPN and want malware protection on the same bill
- Households that fit within 5 covered devices
- People who want one subscription across security tools rather than several separate buys
Who should look elsewhere
- Apple Inc. users, who get security features across iOS, iPadOS and macOS from the operating system itself
- Comodo (Xcitium) users who need room for 50 devices on a single plan
- ESET Brasil readers after a different first-year quote, since its first-year price is BRL 64.22

Questions about each
Mysterium VPN
What does Mysterium VPN cost month to month and on a long term plan?+
The monthly plan costs $10.49 to $18.49. Longer commitments are cheaper per month, with the long term plan at $2.59 to $4.79 and the longest term running 24 months. Both figures sit above the €7.89 monthly median for the category, so the saving comes from committing rather than from a lower opening rate.
How many devices can one Mysterium VPN account cover?+
One account covers 15 devices, and the plan places 1 of 80 brands on that measure. For context, the median device allowance in the category is 7, so a household with a phone, a laptop, a desktop and a browser extension stays inside the limit.
Surfshark One (Antivirus)
What does Surfshark One cost at the start and after renewal?+
The first-year price is €75.33, and the monthly option is listed at €2.49. Set the opening figure against the group median of €49.95. What a renewal costs depends on the checkout terms, so the total shown at the point of payment is the figure to check.
Does the plan include a VPN or is that bought separately?+
A VPN is bundled into the same plan and listed among the extras, so antivirus and privacy cover arrive on one subscription rather than two. That bundling is what separates this offer from antivirus sold on its own. Around 97.1% of the products in this group also bundle a VPN.
