I started using Guardio because phishing pages are getting harder to spot, even when you know what you’re looking for. AI can now help scammers write convincing messages, copy the tone of a real company and build fake pages without the spelling mistakes or strange formatting that used to give them away.
That leaves more of the work to the person receiving the message. You have to decide whether the email, website and request are genuine, often while somebody is trying to make you act quickly.
I wanted to see whether Guardio could genuinely make that part of being online safer, and whether it deserved a place in our recommendations.
I used it for four months, which gave me plenty of time to see what it was like beyond the initial setup.
Four months later, it’s still installed. That probably tells you where I landed, but there are a few things I think you should know before paying for it.
Here’s what using Guardio was actually like, where I found it useful and who I think it’s worth it for.
Best for straightforward scam and phishing protection while browsing
What I liked most about Guardio was that it caught pages I genuinely could have trusted without the warning.
The fake Netflix page was the clearest example. The branding, colours and layout all looked right. Guardio stopped it before I entered anything, and a closer look showed that the address used a capital ‘I’ in place of the ‘l’ in Netflix.
It also caught a fake banking page that had fooled me at first. Without the warning, I could easily have carried on and entered my details. That’s the kind of situation I wanted Guardio for in the first place.
As fake messages and websites become more convincing, spotting a spelling mistake is no longer a dependable safety check. Guardio looks beyond how polished the page appears and checks the website itself against the information it has about scams and dangerous sites.
Setup took about five minutes, the extension didn’t noticeably slow down my normal browsing and I rarely thought about it unless it blocked something. The dashboard gave me a useful record of the dangers it had found without demanding that I check it every day.
The weaker parts were the safe websites it blocked by mistake and the price. Guardio occasionally stopped me opening legitimate regional websites, newer shops and niche forums I wanted to use. At $119.88 annually for one person, it also costs more than I’d expect from something that still needs to sit alongside conventional antivirus protection.
I’d recommend Guardio if scams, phishing links and fake websites are the risks you most want help with. Phishing is when somebody pretends to be a trusted company or person to trick you into sharing information such as a password or card number.
If you need protection across your whole device, including help finding and removing harmful software, I’d start with antivirus with scam and phishing protection instead.
| Category | Score | My assessment |
|---|---|---|
| Features | 3.6/5 | Strong protection against scam and phishing websites, with alerts if your email address or phone number appears in a known data breach |
| Security | 4.1/5 | It caught convincing threats during my test, although it needs a working internet connection to check websites properly |
| Ease of use | 4.5/5 | Setup took around five minutes and I rarely had to think about it afterwards |
| Value | 3.2/5 | Useful specialist protection, but expensive when it doesn’t replace full antivirus software |
| Overall | 4/5 | A strong extra layer of protection for people particularly concerned about scams and phishing |
Guardio is a security service that works mainly inside your web browser. It’s designed to stop scams, phishing pages, dangerous websites, harmful downloads and unsafe browser extensions.
A browser extension is a small add-on installed in Chrome, Edge or another supported browser. Guardio uses that access to check the links and websites you open. If it believes something is dangerous, it can warn you or stop the page before you continue.
Paid accounts can also tell you if an email address or phone number appears in information exposed during a known data breach. A data breach happens when private information is stolen from or accidentally exposed by a company or online service.
I think of Guardio as an extra layer between me and the parts of the internet designed to trick me.
That extra check has become more useful as AI has made scams easier to produce. A fake message can now be well written, personalised with information found online and made to sound like a company or person you recognise. A polished message still isn’t proof that the person behind it is genuine.
Guardio doesn’t decide whether every message you receive is truthful. It can check the link, website or connected account for signs of danger and give you a reason to stop before sharing anything.
Antivirus software focuses more heavily on the whole device. It can scan stored files, find harmful software that’s already present and watch areas outside the browser. Guardio concentrates on stopping dangerous online interactions before they go any further.
That narrower focus worked well for me. The most useful warnings appeared when a website looked safe enough that I might otherwise have continued.
I had Guardio installed for four months. For the first part of that period, I simply left it running while I used the internet normally. I then spent roughly two months paying closer attention to what it blocked, how the dashboard behaved and where the protection became less reliable.
I installed the extension on Chrome, which is my main browser, and Edge, which I use less often. I used both for work, banking, online shopping, email, social media and general browsing.
There wasn’t an elaborate laboratory setup. I wanted to see what Guardio did while I was using the internet in the same way I normally would.
Most of the time, it did very little visibly. It sat in the background until I reached something it thought was dangerous.
I also used it while travelling. When my Wi-Fi became unreliable in Da Nang, Guardio’s warnings seemed less consistent. That didn’t happen every time the connection slowed, but it happened enough for me to notice.
Guardio checks websites against information held online, including the latest details it has about scams and dangerous sites. It needs a working internet connection to do that properly.
That’s worth knowing if you regularly work while travelling or depend on patchy public Wi-Fi.
The warning I remember most came after I clicked what looked like a Netflix account-update link in a promotional email.
The page was convincing. It had the familiar branding, colours and layout, and nothing immediately made me think I’d landed somewhere dangerous.
Guardio blocked it before I entered my login details.
When I checked the address more carefully, the domain used ‘netfIix-account.com’, with a capital ‘I’ replacing the lowercase ‘l’. It was obvious once I knew what I was looking for and remarkably easy to miss before that.
Without the warning, I could easily have carried on and entered my details.
This is also why advice such as ‘look for bad spelling’ no longer goes far enough. AI can help scammers produce cleaner copy and more convincing designs. You still need to check the address, the request and the account through a route you already trust.
Guardio helped with the dangerous website. It couldn’t tell me whether every part of the email was genuine or whether a different Netflix-looking page would always be caught.
Guardio also warned me about a fake banking page that had fooled me at first.
The familiar logo and login form made it feel legitimate. Guardio’s warning gave me a reason to stop and check before entering anything.
I’d like to say I would always have spotted it eventually, but I can’t say that with any confidence. Phishing pages work because they catch you at the moment you’re expecting to see something familiar.
If a bank, delivery company or subscription service asks you to take action, I’d still open its official app or type the address myself rather than trusting the link. Guardio gives me another layer of protection, not permission to stop checking.
Guardio also blocked suspicious links and websites I reached through email or normal browsing.
I liked that its warnings usually explained what it had found rather than simply giving me a vague red screen. If something interrupts what I’m doing, I want enough information to decide whether the warning makes sense.
Guardio sometimes blocked websites that were actually safe. Security companies call these ‘false positives’, but from my side it simply meant Guardio occasionally stopped me opening a legitimate site I wanted to use.
Across the four months I used it, that happened around 15 to 20 times.
Most of the affected sites were smaller international websites, niche forums, regional news sources and newer online shops. These sites may not have been around long enough for Guardio to feel confident that they were safe.
The most frustrating example was a Nairobi news site I needed for work. I tried three times to tell Guardio the site was safe so it would stop blocking it.
I could choose to ignore the warnings, but they still interrupted what I was doing. If a security tool warns you too often about safe pages, there’s also a risk that you’ll get into the habit of clicking past every warning without checking.
My browsing probably exposed this problem more than it would for somebody who mainly visits large British or American websites. I regularly use regional and international sources, so I’m more likely to visit legitimate sites Guardio doesn’t know much about yet.
I’d still rather stop and check an occasional safe website than discover Guardio had quietly allowed a convincing phishing page through. I’d just like it to handle smaller legitimate sites more consistently.
Guardio is strongest when a danger reaches you through a supported browser, connected email account or mobile feature. It doesn’t replace security software that protects the whole device.
It isn’t designed to find every piece of malware already stored on your computer. Malware simply means harmful software. It can include programs designed to steal information, damage files or give somebody else access to your device.
Guardio also doesn’t provide the same whole-device protection against ransomware, infected USB drives, unsafe applications or attacks through your home or public network. Ransomware is harmful software that can lock your files or device and demand payment to release them.
Its data-breach alerts can tell you that information connected to your account has been exposed. They can’t undo the breach, guarantee that nobody has used the information or recover money lost to fraud.
Guardio also can’t prove that a person, message or offer is genuine simply because it doesn’t block the page. A new scam may not have been reported yet. A criminal may use a legitimate platform, a recently created website or a real account they’ve taken over.
This becomes particularly important when AI is involved. Guardio may help stop the link inside an AI-written phishing email, but it can’t always tell whether the words, image, voice note or person contacting you are genuine.
If somebody asks for money, a password, a security code or sensitive information, verify the request through another route. Call the organisation using a number from its official website, open its app directly or contact the person using details you already have.
Mobile protection also differs from desktop protection. Guardio has Android and iOS apps, but the features aren’t identical. Its current information specifically lists dangerous-website blocking while browsing as an iPhone and iPad feature. Other mobile tools include security warnings, checks for exposed personal details and scam-message protection where supported.
Guardio also needs a reliable internet connection to check the latest information about dangerous websites. I saw the practical effect of that when my Wi-Fi became unstable in Da Nang.
For me, this makes Guardio much easier to place. I’d use it to reduce the chance of falling for a malicious link, fake website or phishing page. I’d use antivirus software for wider protection across the whole device.
If you’d prefer broader protection in one package, compare the options in our guide to antivirus with scam and phishing protection.
This is Guardio’s strongest feature and the main reason I kept it installed.
It checks websites and links for signs that somebody may be pretending to be a trusted company or trying to steal your information. If Guardio believes a page is dangerous, it can stop the page and explain the risk before you continue.
The Netflix and banking pages showed me that this worked against scams convincing enough to pass my first visual check.
That’s increasingly useful when scammers can use AI to remove obvious mistakes and make a message sound more natural. Guardio checks the link and website rather than judging the quality of the writing.
Guardio checks websites against known dangerous sites and looks for other warning signs before allowing normal access.
This is most useful when the warning appears before you’ve entered a password, downloaded a file or given a fraudulent shop your payment details.
Because Guardio sometimes blocked safe websites during my test, I wouldn’t assume every warning proves that a site is dangerous. I would stop and check the website through another trusted source before choosing to continue.
I also wouldn’t assume that a page is safe simply because Guardio allows it to open. No security product knows about every new scam immediately.
Guardio checks files downloaded through supported browsers and can stop a download it believes is dangerous.
That can help when a fake update page, hacked website or misleading advert tries to persuade you to download harmful software.
I’d still scan downloaded files with antivirus software. Guardio checks what’s coming through the browser, while antivirus software can check the file and the wider device.
Browser extensions are small add-ons that give your browser extra features. Some can see the websites you visit, change your search results or access information you enter online.
A dangerous or hacked extension could misuse that access. Guardio can identify and disable extensions it believes are unsafe.
I didn’t find a harmful extension during my test, so this is a feature Guardio currently provides rather than something I personally saw working.
Paid accounts can monitor up to five email addresses. Guardio can also check a phone number through its mobile service where the feature is supported.
It searches databases containing information exposed in known data breaches and alerts you if it finds your details.
An alert gives you somewhere to begin. I’d change the affected passwords, turn on two-step login protection and check the account for activity I didn’t recognise.
I wouldn’t assume the alert means Guardio has fixed the problem for me. It’s telling me what has been exposed so I can act.
Guardio can point out risks connected to accounts and services you link to it.
For example, it may tell you that information connected to an account has appeared in a breach or recommend steps you can take to make the account safer.
I found that more useful than simply seeing a list of blocked websites. It helped me understand which account needed attention and what I could do next.
These features also mean Guardio may need to examine information connected to your browsing, accounts or messages. I explain that more fully in the privacy section.
The dashboard shows the dangers Guardio has blocked, the personal details it’s monitoring and any action it thinks you should take.
I checked it roughly once a week, usually out of curiosity or because I wanted more information about a warning. I didn’t feel I needed to monitor it every day.
That suited me. Guardio stayed in the background, and the dashboard was there when I wanted to understand what it had found.
Guardio’s desktop extension currently supports Chrome, Edge and other browsers built using the same underlying technology as Chrome. These include browsers such as Brave and Opera.
It works on compatible Windows, Mac and Linux computers.
Guardio doesn’t currently support Firefox or Safari through its desktop extension.
That’s an important limitation. If Firefox or Safari is your main browser, I wouldn’t pay for Guardio until you’d confirmed it works where you need it.
The mobile app is available for Android and iOS, but the protection isn’t identical across the two systems and it doesn’t reproduce every desktop feature.
Guardio says one account can protect several compatible devices. The number of separate people covered depends on whether you choose Individual, Duo or Family membership.
Yes. Setup took me about five minutes.
I added the extension, allowed it to access the parts of my browser it needed, created an account and completed the short introduction. I didn’t have to work through pages of technical settings before it started protecting me.
During normal use, Guardio stayed out of the way. I didn’t notice a meaningful slowdown in Chrome or Edge, and the extension only demanded my attention when it blocked something or needed me to make a decision.
The warnings use straightforward explanations rather than expecting you to understand security terminology. I think that makes Guardio suitable for somebody who wants more protection without managing a complicated security product.
Telling Guardio to allow safe websites was less smooth. It usually worked, but the Nairobi news-site incident showed that it doesn’t always stop blocking a site as neatly as it should.
Guardio has apps for Android and iOS, but I wouldn’t assume every desktop feature follows you onto your phone.
On mobile, Guardio can warn you about security problems, check whether your personal details have been exposed and filter some scam messages. The exact protection depends on the type of phone you use.
Guardio’s current information specifically lists dangerous-website blocking while browsing as an iOS feature.
I’d treat the app as an extension of the wider Guardio account rather than a mobile copy of the desktop browser extension.
If mobile protection is the main reason you’re considering Guardio, check that the feature you want works on your phone before paying. ‘Available on Android and iOS’ doesn’t mean both versions do exactly the same thing.
Yes. Guardio is a legitimate security service with working browser extensions, mobile apps, published subscription plans and established customer support.
More importantly for me, the product performed its main job. It blocked convincing phishing pages, explained why it had stopped them and kept a record of what it found.
Some of the distrust around Guardio comes from billing confusion, cancellation complaints, safe sites being blocked by mistake or people expecting it to be a full antivirus product. Those are fair things to investigate, but they don’t make Guardio itself a scam.
The more useful question is whether its particular type of protection is worth paying for. I think it can be when phishing and scam websites are your main concern. It becomes harder to justify if you still need to buy several other security products around it.
Nothing about my four months using Guardio made me think I was dealing with harmful software or a fake security service.
Guardio uses encrypted connections, which means information is scrambled while it travels between your device and Guardio so it’s harder for somebody else to read. Guardio also says it doesn’t store your complete payment-card details on its own systems.
The browser extension asks for wide access because it needs to examine the websites you open and look for danger.
I’d still pay attention to what you allow it to access. Depending on the features you turn on, Guardio’s privacy policy says it may process your account-registration details, browsing activity, online-account settings, text-message content, information from connected online storage, public social-media information and details found in known data breaches.
Several of its features couldn’t work without checking information connected to a possible threat. You should still understand what you’re sharing rather than installing any security extension without looking at its privacy settings.
Guardio says it doesn’t sell the information collected through these monitoring features. Its policy also says it may keep information connected to suspected dangers and security risks.
I’m comfortable using Guardio for the protection it gives me, but I’d only connect the accounts and services needed for the features I intended to use.
Guardio offers Free, Individual, Duo and Family plans.
| Plan | If you pay monthly | If you pay yearly | People covered |
|---|---|---|---|
| Free | $0 | $0 | 1 |
| Individual | $14.99 each month | $119.88 charged upfront, equal to $9.99 a month | 1 |
| Duo | $22.99 each month | $183.90 charged upfront, equal to $7.67 per person each month | 2 |
| Family | $34.99 each month | $279.90 charged upfront, equal to $4.67 per person each month | 5 |
If you choose a yearly plan, Guardio charges the full amount in one payment. The monthly figure shown beside it is there to help you compare the cost. Guardio doesn’t take that smaller amount from your card each month.
Guardio no longer offers a standard free trial. A new paid subscription starts immediately, so don’t enter your payment details expecting to have a trial period in which to decide.
The Free plan gives you basic browser warnings and lets you run a manual security check. Paid plans add automatic blocking of scam and phishing pages, alerts when personal details appear in a known data breach and support across more compatible devices.
The Individual plan is the hardest for me to recommend on price alone. Paying $119.88 upfront for protection focused mainly on browsing feels expensive when some full security packages cost a similar amount.
Duo and Family membership make more sense when several people genuinely need the protection. I’d still compare the total cost and features with a broader security service before committing.
You can compare Guardio with a wider identity and security product in Aura vs Guardio.
Guardio’s monthly subscriptions renew every month. Yearly subscriptions are charged upfront and renew for another full year unless you cancel.
Your subscription page should show the next renewal date and the amount Guardio expects to charge. I’d check both after subscribing and keep the confirmation email.
Removing Guardio from your browser or deleting the mobile app doesn’t stop the subscription. You need to cancel the membership separately.
The yearly pricing can be confusing. If you see ‘$9.99 a month’ beside a yearly Individual plan, Guardio will charge $119.88 upfront rather than taking $9.99 each month.
Guardio says customers who meant to choose monthly billing but accidentally selected yearly billing should contact support within three days of the charge. It reviews these cases but doesn’t promise an automatic refund.
How you cancel depends on where you subscribed.
Cancel through the Subscriptions area of your Apple account.
Cancel through ‘Payments and subscriptions’ in Google Play.
Cancelling stops the next payment. It doesn’t normally end your protection immediately or return money for the unused part of your current subscription.
Uninstalling Guardio doesn’t cancel the subscription.
Guardio doesn’t promise an automatic refund to everybody who changes their mind.
Whether you receive one depends on what happened and how you paid. Guardio tells customers to check the chosen plan, payment schedule and full amount before confirming a purchase.
If you accidentally selected yearly rather than monthly billing, contact Guardio within three days. Purchases made through Apple or Google Play may need to follow the app store’s own refund process.
I’d treat the payment as final unless Guardio or the app store tells you otherwise. If I wasn’t sure Guardio suited me, I’d start with one monthly payment even though it costs more per month.
During my test, I contacted Guardio through its online support form.
A billing question received a response within a day. A technical question about safe websites being blocked took four days and two follow-ups to resolve.
The answers were useful once they arrived and didn’t read like generic scripts. The wait was the frustrating part.
Guardio’s current support options are broader than the ones I used. It now lists email, contact through the dashboard and telephone support, with additional specialist help on selected plans.
I haven’t tested the current telephone service, so I can’t tell you how well it works. My own support experience is based on the online conversations I actually had.
Guardio and antivirus software can both help with dangerous websites and downloads, but they don’t do the same job.
| Type of protection | Guardio | Full antivirus software |
|---|---|---|
| Stops fake login and phishing pages | A main part of the service | Usually included |
| Warns about scam websites | A main part of the service | Depends on the provider |
| Checks browser extensions for danger | Included | Depends on the provider |
| Warns if personal details appear in a known data breach | Included with eligible plans | Often included in wider packages |
| Scans the whole device for harmful software | No | Yes |
| Finds and removes harmful software | No | Yes |
| Protects against software that locks files and demands payment | No dedicated whole-device protection | Commonly included |
| Monitors incoming and outgoing internet connections | No | Often included through a firewall |
| Hides your internet connection through a VPN | No | Frequently bundled |
| Stores and creates passwords | No | Frequently bundled |
I’d choose Guardio if my main concern was being tricked by a convincing website, message or link.
I’d choose full antivirus software if I needed wider protection across files, applications, downloads, internet connections and the rest of the device.
Some people will benefit from using both. Others will get better value from one broader product that already includes strong website protection.
Guardio and Aura are built for different jobs.
Guardio is more specialised. It focuses mainly on browsing, phishing, scam websites and other dangerous online interactions.
Aura offers wider identity and security protection. Depending on the plan and country, that may include alerts about possible identity theft, antivirus software, a VPN and help if somebody uses your personal information fraudulently.
Some of Aura’s strongest identity and financial features are aimed mainly at US customers.
I’d choose Guardio if I already had antivirus software and wanted stronger protection against fake websites and phishing. I’d consider Aura if identity theft and wider online protection were my larger concern.
Our full Aura vs Guardio comparison explains the differences in more detail.
I’d recommend Guardio to
I’d choose something else if
Four months with Guardio gave me enough time to see both sides of it.
It blocked safe websites often enough to become annoying, especially when I was researching smaller international sites. The unreliable connection in Da Nang also showed me that Guardio’s website checks become less reassuring when the internet behind them is struggling.
I still kept Guardio installed.
The fake Netflix and banking pages are the reason. Both looked legitimate enough for me to continue, and Guardio stopped me before I handed over anything valuable.
Scams are becoming easier to produce and harder to judge by appearance alone. AI can help somebody create a convincing message or copy the tone of a real company, but it can’t make a dangerous website safe. Guardio gives me another way to check what sits behind the message.
It doesn’t remove the need to think. A page that Guardio doesn’t block isn’t automatically genuine, and the service can’t confirm who created a message, whether a voice is real or whether somebody contacting me is who they claim to be.
I also liked how little attention it needed. Setup took around five minutes, normal browsing felt unchanged and the dashboard was there when I wanted to understand what had happened.
The price stops me recommending it to everyone. Guardio provides one particular layer of security rather than protecting the whole device, and the Individual plan costs enough to invite comparisons with products that also include antivirus software, a VPN and other protection.
I’d pay for it if phishing and scam websites were a recurring concern, especially if several family members needed protection. I’d skip it if I only wanted basic browser warnings or still needed to buy every other part of my security setup separately.
Guardio did the job I wanted it to do. It caught convincing threats without making itself the centre of my browsing, and that was useful enough for me to keep it.
