SafeToOpen stopping a fake Instagram login — and spelling out exactly why it’s unsafe, before you ever type a password.
One lightweight extension working in real time: it catches phishing and brand-new scam pages, blocks known-malicious sites and downloads from one of the largest threat feeds, and warns you before passwords or card numbers reach the wrong site — all without collecting your browsing data.
SafeToOpen stopping a fake Instagram login — and spelling out exactly why it’s unsafe, before you ever type a password.
One of the largest, ever-growing threat feeds of known-bad sites and malware — refreshed every minute — stops recognised threats instantly.
VisionAI and Deeper Analysis judge a page by what it is — its appearance and its hidden code — catching brand-new scam sites no blocklist knows yet.
Warns and masks when card numbers or personal data are about to be pasted into a website — keeping private information on your device.
Drag the handle: on the left is the login page a visitor sees. On the right is what SafeToOpen’s Deeper Analysis sees — the markup and scripts hidden beneath the surface.
Drag the handle left to reveal the code · illustrative of what Deeper Analysis flags, not a literal report.
Security at the point of risk, plus privacy controls that keep your browsing yours.
Blocks known phishing, malware and scam sites the moment you land on them — drawing on one of the largest databases of malicious URLs anywhere, refreshed every minute.
Automatically scans risky pages to detect phishing or scams — catching brand-new sites no blocklist knows yet.
Protects you from downloading known malicious files and viruses, with a clear warning before anything lands on your device.
Blocks known trackers from collecting your data and keeps your searches private — privacy and protection in one place.
Code is only half the story. VisionAI looks at the visible page — the logo, the layout, the sign-in form — and recognises when a page is dressed up to impersonate a brand you trust. That's how it catches never-before-seen attacks that have no bad code to flag yet.
Edge Assist is a small helper that sticks to the side of any page — drag it wherever you like. One click opens its menu, where you can pause protection, hide it, or ask "What is this site?" to learn what a page actually is before you trust it.
"What is this site?" explains the purpose of the page's domain name in plain language — so you can judge for yourself whether that matches what the website in front of you actually claims to be.
As the page loads, a warning toast appears. Open it to see exactly what SafeToOpen flagged — then open Deeper Analysis to understand why the page is dangerous. Deeper Analysis is available on Plus plans.
“A preferred option for phishing detection.”
In independent research evaluating browser extensions against simulated spear-phishing attacks, SafeToOpen was found to be an effective option for phishing detection — alerting users to threats and blocking malicious connections in controlled tests.
Read the researchEvery unknown page is judged on what it actually is — not whether someone reported it first.
The moment you reach a risky page, the extension analyses it — before you enter anything.
VisionAI reads the page the way a person would — the logo, layout and behaviour. Deeper Analysis works like an X-ray, seeing through to the hidden markup and scripts beneath the surface. Two independent lenses, each as effective as the other, together catching what either alone might miss.
A clear ribbon stops you before you submit anything — and tells you what is wrong, what to look for, and what to do next.
Most security tools just say “blocked” and leave you none the wiser. SafeToOpen explains itself — so every warning makes you a little harder to fool next time.
The warning names the specific problem in plain language — a lookalike domain, a fake login, a brand-new site impersonating one you trust — not a cryptic error code.
It points out the tell-tale signs on this page, so you start to recognise the same red flags yourself — the misspelt address, the wrong domain, the details that don’t add up.
It tells you the safe next step — leave the page, go to the real site directly, report it — turning a moment of risk into a clear, confident decision.
Over time, a workforce protected by SafeToOpen becomes a workforce that spots scams on its own — security awareness that happens in the moment, not in an annual training slot.
Real-time phishing detection is the headline. The same extension also blocks known threats coming in — and stops sensitive data going out.
A huge blocklist of known-bad websites and malware — refreshed every minute — stops recognized threats instantly, layered underneath the real-time zero-day engine.
SafeToOpen watches for sensitive information — like passwords, personal details or card numbers — being pasted into websites, warns the user in real time, and reports the event to your admin and SOC.
SafeToOpen never collects, stores, or sells your browsing data. It blocks known trackers, keeps your searches private, and only checks what it needs to keep you safe.
Free blocks the threats already known to be dangerous. Plus adds the real-time detection that catches brand-new, never-before-seen attacks.

Instead of relying on a blocklist of reported URLs, SafeToOpen analyses each risky page as it loads — its appearance, structure and behaviour — and recognises a scam by what it actually is. That lets it catch never-before-seen (zero-day) phishing pages in seconds.
No. SafeToOpen never collects, stores, or sells your browsing data. It also blocks known trackers from collecting it, and keeps your searches private.
