Pros and cons
AdBlocker Ultimate
Pros
- Wide coverage across Windows, macOS and Android for desktop, mobile and browser use
- DNS privacy options include doh, dot and dnscrypt on supported Android builds
- Focused ad blocking scope via ad blocker that keeps setup clear
Cons
- Closed review path, as open source is no, which limits outside code checks
- Support runs on email and help centre only, which limits direct contact routes
Surfshark Alert
Pros
- Monthly price of €2.49 places Surfshark Alert 2 of 54 brands in our data, near the floor of the monthly prices we compare
- Deloitte has independently audited the no-logs policy, and the server network runs in RAM rather than writing anything to disk, which is the main privacy claim to weigh
- The same Surfshark subscription covers private dns, ad blocker and search alongside identity alerts, and it runs on Windows, macOS and Linux from phones to routers and consoles, so a single vendor covers monitoring and browsing
Cons
- Phone support is not among its support channels (chat, email and help centre), which matters most when a fraud alert needs an answer the same day
- Insurance of $1,000,000 ranks 10 of 45 brands, so a bigger payout means a bigger bill, as at Norton or LifeLock
Who each suits
AdBlocker Ultimate
Who it suits
- Everyday browser readers who want free blocking before paying for wider cover
- Multi browser households that want the same ad blocker across desktop and mobile
Who should look elsewhere
- Choose DeleteMe for data broker removal rather than browser ad blocking
- Choose addy.io for masked mail handling rather than page level ad blocking
Surfshark Alert
Who it suits
- Readers who mainly want alerts on their personal details rather than a large insurance payout, and who weigh the entry price before anything else on the plan
- People already paying for Surfshark who want alerts, private DNS, ad blocking and private search in a single account instead of separate tools
- Households that treat an audited no-logs policy and a RAM server network as part of identity protection, and who are comfortable starting on a short trial
Who should look elsewhere
- LifeLock and Norton readers who rank the insurance payout first, since LifeLock runs $10.42 to $34.99 a month and Norton $34.99 a month
- Allstate Identity Protection readers who want identity monitoring sold on its own at $3 a month rather than bundled with DNS and search
- Readers who want a standing free tier, since the free plan is no and the trial is limited to 7-day free trial, 3 devices, so testing is short

Questions about each

Yes. The model is listed as free, so browser blocking starts without charge. Paid app cover is separate for system wide blocking, so check which placement matches the devices used for daily browsing.
What are the limits of the free version+
Limits are described as Free browser extension; paid app for system-wide blocking. That means browser extension use is free, while full system wide blocking sits in the paid app. Readers who only need browser cover can stay free, while wider cover needs the paid tier.
Surfshark Alert
How much does Surfshark Alert cost each month?+
Surfshark Alert runs at €2.49 a month and ranks 2 of 54 brands on monthly price. A budget entry price draws most readers here, and the renewal figure is worth reading before you commit to a term.
Is there a free plan or a free trial?+
There is no free plan. The free trial lasts 7 days, and 7-day free trial, 3 devices sets the terms of that look. It is a short taste of the alerts rather than a free tier you can keep.
