Guardio vs Surfshark One: Block sites or scan Gmail?

Surfshark One is the better deal for most people. It bundles an AI email scam checker with leak alerts, antivirus and a VPN. Guardio is worth it only if you want scam sites blocked in the browser before you click.

Our verdict

Surfshark One is the wider buy. It costs €2.79 a month over the first term and brings antivirus, a VPN, leak alerts and the email scam checker. Guardio Individual costs $14.99 a month and does one job. The two bill in different currencies. A straight price ranking would mislead. Weigh what each one covers instead.

Guardio Individual protects one member on phone, tablet and computer. Guardio wins on one point. It stops a scam page before it loads. You never have to ask for that check. The Surfshark email check runs only when you click to scan, on Gmail in Chrome and nowhere else.

Pick Surfshark One if you want one subscription against several risks. Pick Guardio if browser blocking is the thing you actually want. One+ costs €4.49 a month. Surfshark lists the same features under One and One+ on its pricing page. Neither brand detects a cloned voice.

A sensible pick if you want scam filtering, leak alerts and antivirus under one login. Data-broker removal sits one step up, in One+. The weak spot is transparency on cost. The introductory price runs for 27 months and the pricing page does not state the renewal price.Editorial team, on Surfshark One

Frequently asked questions

Does Surfshark One check my email with AI?

Yes, on Gmail in Chrome. Surfshark says it uses artificial intelligence to detect phishing patterns in emails. The check sits in the Surfshark browser extension and runs when you click to scan. It does not filter your whole inbox by itself.

Is Guardio cheaper than Surfshark One?

That has no answer in one number. Guardio Individual costs $14.99 a month in dollars, or $119.88 a year billed yearly. Surfshark One costs €2.79 a month in euros over the first term. Surfshark buys more for that money. Antivirus and a VPN come with it.

Does Guardio work in Firefox or Safari?

Not on a computer. Guardio names Chrome and other Chromium browsers such as Microsoft Edge, Opera and Vivaldi. Firefox and Safari are not on that list. The Surfshark email check needs Chrome as well.

What does Surfshark Alert do?

It warns you when your data turns up in a leak. Surfshark names your email address and passwords. Card numbers and ID documents count too. Alert sits in Surfshark One and above. The identity theft coverage is for US residents only.
