A single click on the wrong page or email is all it takes to lose money, accounts, or company data. SafeToOpen steps in at that moment — its browser extension flags scam pages and blocks malicious downloads as they load, while its Outlook and Gmail add-in inspects suspicious mail and catches advanced fraud like business email compromise. And it never collects your browsing data.
The same real-time detection engine — shaped for your home or your organization.
Free browser protection on your devices. Upgrade to Individual or Family Plus for email security and cover for everyone at home.
Protect employees, customers and your brand at scale — small and medium business, MSPs, enterprise and government, with central management and mixed Plus + Executive seats.
Every unknown page is judged on what it actually is — not whether someone reported it first.
A risky page or email is analysed the instant you reach it — before you enter anything.
VisionAI — our detection engine that reads a page the way a person would — recognises a scam by how it looks and behaves, so even brand-new attacks are caught.
You get a clear warning before any data is entered or a file is opened. Threat handled.
Most people and businesses already have security tools — and assume they're covered. But each guards a different door, and none of them watches the one that matters most: the page itself, at the moment you're about to trust it.
Antivirus hunts malicious files; a phishing page drops none. MFA protects your password — but modern scams steal the session after you pass it. Neither judges the fake page in front of you.
Filters catch what's already been reported. A phishing site spun up an hour ago is on no blocklist yet — and that first hour is when most victims are caught.
It judges the actual page and email in real time, at the point of click — catching the zero-day scam the rest of your stack can't see. It works alongside what you already have.
Keep your antivirus, MFA and spam filter — they all matter. SafeToOpen adds the one layer they leave open.
The same detection wherever a threat reaches you — your pages, your inbox, your brand.
Automatically scans risky pages to detect phishing or scams — and protects your privacy at the same time.
Verify a suspicious email in seconds, with a clear trust score before you act on it.
Detects sites impersonating your brand and alerts your security team and partners before customers are exposed.
Whether the threat arrives as a link in an email or a page that loads in a tab, SafeToOpen is already there — analysing, deciding and acting before you have to. And it does it without collecting or selling your data.

"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!"

'Zero-day' is the industry term for a scam page so new that no warning list has seen it yet. Instead of waiting for someone to report it, SafeToOpen analyses each risky page as it loads and recognises a scam by how it looks and behaves — so brand-new attacks are blocked in seconds.
No. SafeToOpen never collects, stores, or sells your browsing data. It also blocks known trackers from collecting it, keeps your searches private, and deletes analysis logs after each check.
The browser extension has a free plan for personal use with no sign-up — it blocks known phishing, scam and malware sites. Catching brand-new (zero-day) scams, Paste Guard and email security are on the paid Plus and Executive plans.
SafeToOpen works in Chrome, Edge, Safari, Firefox and on iOS, and protects email in both Microsoft Outlook and Gmail.
Traditional tools rely on lists of known-bad URLs and files, so they miss brand-new attacks. SafeToOpen analyses the page or email itself at the moment of risk, catching threats that have never been seen before — and it works alongside your existing antivirus and filters.
