Extend Your Defenses to Protect Customer Sessions

Cybercrime has moved into the customer’s browser. MirrorTab works with your existing security stack—Cloudflare, Akamai, WAFs, and fraud tools—to stop session takeovers, AI bots, malware, and malicious extensions inside authenticated sessions.

No code changes. No plugins. No customer installs.

We Protect Customer Sessions From:

Session Takeovers

Concurrent Session Exploitation

Content Scraping

Automated Money Movement

Transaction Fraud

Malicious Browser Extensions

Cookie and Token Theft

Formjacking

API Abuse

Data Leakage

AI-Powered Bots and Automation

Data Harvesting

Script Injection

Account Takeover Fraud

Untrusted Device Access

Session Defense Without the Friction

Traditional security stops at the edge. MirrorTab protects inside the session—securing high-risk flows like transactions, withdrawals, password resets, and account changes with server-side isolation.

How MirrorTab Works

No DOM exposure

Your app’s code, APIs, and data never touch the customer’s browser.

No data leakage or fraud

Even on compromised devices, your app stays protected.

No plugins or agents

Fully server-side—no code changes, no user impact.

Triggers via WAF, bot score, auth state, or feature flag.

Fully server-side. No code. No customer installs.

Works with any edge platform (CDN, WAF, etc.).

Breakthrough performance. Nothing else compares.

Your Web Sessions. Fully Protected. Zero Friction.

Your apps work as intended. Content loads accurately. Customer interactions stay smooth. Performance remains strong—even on low bandwidth.

Improves performance over
low bandwith connections.

The Story Behind MirrorTab

MirrorTab was founded by the CTO and co-founder of Honey (acquired by PayPal).

At Honey, we built the world’s most popular browser extension by working deep in the DOM.

Now, we’re flipping the model—removing the DOM entirely to protect customer sessions from extensions, AI bots, malware, and in-browser fraud.

Man-in-the-Browser Attack Explained and Mitigated

In order to perform MitB attacks, a hacker must progress through the following steps in the attack chain:

The Trojan infects the computer’s software, either OS or Application.

The Trojan installs an extension into the browser configuration, so that it will be loaded next time the browser starts.

At some later time, the user restarts the browser.

The browser loads the extension.

The extension registers a handler for every page-load.

The Trojan infects the computer’s software, either OS or Application.

The user logs in securely on to for example 
https://secure.original.site/

When the handler detects a page-load for a specific pattern in its targeted list (for example https://secure.original.site/account/do_transaction) it registers a button event handler.

When the submit button is pressed, the extension extracts all data from all form fields through the DOM interface in the browser, and remembers the values.

MirrorTab prevents the extension from knowing the field was submitted or extracting the data.

The extension modifies the values through the DOM interface.

MirrorTab stops DOM modification.

The extension tells the browser to continue to submit the form to the server.

Extension cannot view/modify network or API traffic.

The browser sends the form, including the modified values, to the server.

Extension cannot view/modify network or API traffic.

The server receives the modified values in the form as a normal request. The server cannot differentiate between the original values and the modified values, or detect the changes.

Extension cannot view/modify network or API traffic.

The server performs the transaction and generates a receipt.

Would only accept true form, due to immutable DOM.

The browser receives the receipt for the modified transaction.

The browser cannot modify receipt for modified transaction due to MirrorTab.

The extension detects the https://secure.original.site/account/receipt URL, scans the HTML for the receipt fields, and replaces the modified data in the receipt with the original data that it remembered in the HTML.

Extension cannot modify receipt fields due to MirrorTab.

The browser displays the modified receipt with the original details.

MirrorTab breaks attack chain.

The user thinks that the original transaction was received by the server intact and authorized correctly.

MirrorTab breaks attack chain.

What is the man-in-the-browser attack?

The Man-in-the-Browser attack is the same approach as Manipulator-in-the-middle attack, but in this case a Trojan Horse is used to intercept and manipulate calls between the main application's executable (ex: the browser) and its security mechanisms or libraries on-the-fly.
