…and here’s Otto for real — spotting a fake Booking.com page and warning “this page is unsafe” before anyone enters card details.
Phishing doesn't care how tech-savvy you are. SafeToOpen quietly blocks fake sites, risky downloads and scam emails in real time. Protect just yourself, or cover your whole household — kids, parents and grandparents alike — without anyone watching what you browse.
Whether it's just you or your whole household, SafeToOpen is two simple apps working together — one watching your email, one watching your browser. Both run quietly in the background — on your computer and your phone, including Microsoft Edge on Android, set up the same way as on desktop.
Protects your inbox
Not sure about an email? One click tells you if it's safe — checking the links, attachments and sender. Works in Outlook and Gmail, on every device.

If someone clicks a scam link, SafeToOpen spots the fake page as it loads and blocks it — even brand-new scams that haven't been reported anywhere yet.

Most people miss a few. Take our 2-minute “spot the fake” test together — then send it to the family group chat and compare scores.
Real-time protection for the everyday traps, so no one in your home has to be a security expert.
Bank lookalikes, fake delivery notices, prize and refund scams — blocked before anyone types a detail.
Stops malicious files and viruses from landing on your laptop or phone in the first place.
Verify a suspicious message in one click before acting — handy for less confident family members.
A lot of "free" tools pay for themselves by harvesting your data. SafeToOpen never does. It blocks trackers, keeps searches private, and never sells a thing — so you and your household are safer and more private.
Install the free extension on each device — no sign-up needed to start.
Personal Plus covers up to 5 of your own devices; Family Plus covers up to 5 people, 5 devices each, managed from one simple dashboard.
Protection runs quietly in the background and warns only when something's wrong.
"Great product as I've tried using other anti-phishing products. This one is by far the best I've found, so much so I've also installed it on other family computers. It effectively identifies phishing links and alerts promptly if there's an abnormality. 10/10 recommend!"
"I have had this loaded on my computer for quite some time now and am completely satisfied with the performance on a daily basis and in unusual circumstances. I would and have recommended this security service since I found out about it and will continue to into the future. Thank you for protecting my computer and all the information and activity within it."
"It's really easy to use, which is a huge plus in my book. The folks who made this thing seriously know their stuff, and I would totally recommend it to anyone who wants to feel secure when they're browsing the web."

SafeToOpen is two products, each priced separately — choose one or both. These are the personal plans; business plans live on the full pricing page.
It scans risky pages and emails in real time, blocking phishing and scams before anyone enters a password or opens a dangerous file. Start free on your own browser — family plans cover everyone's devices and let you manage protection from one place.
Partly — but not enough. Chrome, Safari and Edge rely on lists of sites that have already been reported as dangerous, so there's a gap between when a scam launches and when it gets added. Criminals exploit exactly that gap, spinning up brand-new fake pages that haven't been reported anywhere yet. SafeToOpen reads each page as it loads and judges whether it's a fake in real time — so it catches the new scams your browser hasn't heard about. It also blocks trackers and keeps your browsing private, which built-in protection doesn't do.
Start with the free browser protection (no device limit). If you want email security and cover across your devices, Personal Plus is the single-person plan — it covers up to 5 of your own devices — and you can move up to Family Plus later without reinstalling anything.
Yes. Protection runs quietly in the background and warns in plain language when something's unsafe — which helps less technical family members, children and older relatives alike, avoid scams without needing to be security experts.
No. SafeToOpen never collects, stores, or sells browsing data — yours or your family's. It blocks trackers and keeps searches private — protection and privacy aren't a trade-off.
Browser protection is free for personal use with no device limit. Personal Plus covers up to 5 of your own devices, and Family Plus covers up to 5 people, 5 devices each. Email security is a separate product, counted per email address (up to 3 per account) with no device limit. Current prices are just above, and the pricing page has the full comparison.
