About Haven
The Internet is Weird, Bring a Friend.
Haven is a browser extension that checks links, sites, and downloads as you browse. When a page looks right but is not the site it claims to be, Haven tells you before you sign in or share anything. Free for individual use.
A letter from our founder
Why we built Haven
Everyone assumes the internet is safe enough.
We rely on it for everything: signing documents, managing work, shopping, communicating, and logging into the accounts that run our lives. When we open our browser, we trust that what we're seeing is real.
Most of the time, it is.
But increasingly, it isn't.
Phishing sites, look-alike domains, malicious extensions, and deceptive links in emails can quietly trick us into signing in to something that only looks legitimate. These attacks do not require hacking your computer. Reliance on simple human factors: assumption and oversight.
In my decades working in technology, I have seen how easily the web can be manipulated and how difficult it is for even the technically savvy to tell when something is not right. Today, with AI tools capable of generating convincing fake pages and messages in seconds, the gap between real and fake is getting harder to spot.
That is why we built Haven.
Haven adds a layer of verification to your browser so you can know when a site is real before you sign in or share sensitive information. It works quietly in the background, helping detect suspicious links, prevent fake login pages, and protect important sessions without tracking you or selling your data.
We believe security should not feel technical or overwhelming. It should feel calm, simple, and trustworthy.
The internet is not inherently dangerous. But the moments when you log into something important deserve extra certainty.
Haven helps provide that certainty so you can trust what you click and focus on what matters.

Capabilities
What Haven does
Five checks, running while you browse. None of them ask you to become a security expert.
Haven Verified
Confirms you are on the site you meant to visit, not a look-alike built to collect your login.
Link Analysis
Checks where a link actually goes before you follow it.
Extension Disablement
Pauses your other browser extensions while you are on a sensitive site, so they cannot read the page.
Download Guard
Pauses and asks you to confirm when a download starts from an unverified source. Downloads from verified sites are not interrupted.
Email Protection
Flags impersonation in Gmail and Outlook on the web. One banner per message, naming where a link really goes. It never deletes or blocks anything.
What we stand for
Three things we keep coming back to
Make people feel confident, not cautious.
The goal is not to make the internet feel frightening. It is to give you enough context to keep going without second-guessing yourself.
Show up at the second that matters.
Advice after the fact does not help anyone. The useful moment is the one just before you sign in, download, or approve something.
Stay simple enough to actually use.
Safer browsing should not require a security background, a policy document, or a change to how you already work.

Questions
Things people ask us
What is Haven?
Haven is a browser extension that checks links, sites, and downloads while you browse. It confirms you are on the site you meant to visit, flags look-alike domains and fake login pages, and pauses downloads that start from unverified sources, so you can decide what to trust before you enter a password or share something sensitive.
Who makes Haven?
Haven was founded by Brian Silverstein, who serves as Chief Executive Officer. The company is based in California, and is backed by investors including Valley Capital Partners, GV, Ludlow Ventures, and Altman Capital.
Is Haven free?
Haven is free for individual use. Business and MSP plans are paid, and pricing for those is arranged through sales. You can see the full breakdown on the pricing page.
Which browsers does Haven work with?
Haven runs on Google Chrome and on Microsoft Edge, and installs from the Chrome Web Store. Edge users add it from that same listing once extensions from other stores are enabled.
Do I need an account to use Haven?
Yes. Haven provides protection only once you have created an account and signed in. Installing the extension without signing in leaves you unprotected, which is why Haven prompts you to finish setup after install.
Is Haven a VPN or an antivirus?
Neither. A VPN encrypts your connection and an antivirus inspects files on your machine. Haven works at the browser layer, on the question of whether the page, link, or download in front of you is what it claims to be. It is designed to sit alongside those tools rather than replace them. See Haven compared with a VPN.
Does Haven track my browsing or sell my data?
Haven does not sell your personal information and does not share it for cross-context behavioural advertising. The extension sends security information only, such as the hostnames it checks and whether a link was flagged, not your browsing history or the contents of the pages you read. The privacy policy sets out what each Haven product collects.
How do I get help or report a problem?
