MirrorTab, a provider of advanced web application protection, announced it has raised $8.5 million in seed funding. Valley Capital Partners led the round, which also included GV, Ludlow Ventures, Altman Capital Fund, NextGen Venture Partners, and Alumni Ventures.
MirrorTab also dynamically protects web applications without impacting user experience or requiring additional software or plugins. Using isolation technology, MirrorTab removes the browser as an attack surface, obfuscating data, code, and Application Programming Interfaces (APIs) to establish the most secure web sessions. This ensures that sensitive business, personal, and financial information can be shared with confidence. The company plans to use the seed funding to aggressively build out its innovative capabilities and integrations and commercialize its availability.
Before launching MirrorTab, Brian Silverstein (CEO and founder of MirrorTab) co-founded Honey, the shopping rewards browser extension that helps users save money with coupons. And with the surge in AI and increasing attack complexity, he saw how similar technology could be weaponized by bad actors to exploit web sessions without the user or platform ever knowing. As data is rendered into the browser, it becomes exposed to threats such as malware and bad extensions, exposing customers and platforms to fraud and privacy leaks that are invisible to perimeter defenses.
KEY QUOTES:
“Browsers have become the battleground for hacking, bots, and malware. Cyberattacks have evolved, leveraging browsers, AI and automation to evade detection, mimic human-like behavior, and execute attacks that cannot be prevented with typical web security controls. MirrorTab addresses this critical blind spot in traditional detection-based solutions.”
– Brian Silverstein, CEO and founder of MirrorTab
“MirrorTab protects any web platform by securing the session itself—a capability that Web Application Firewalls (WAFs) and bot management tools don’t have. It creates a secure, bot-proof wrapper. Even if the client is untrusted or compromised, MirrorTab ensures sensitive information doesn’t leak, under all circumstances. In high-stakes interactions, such as account takeovers or fraud, MirrorTab provides the gold standard of protection without disrupting the user experience.”
– Allison Miller, MirrorTab Advisor and Former CISO and VP of Trust at Reddit, who also held cybersecurity roles at Bank of America, Google, PayPal, and Visa
“Attackers have discovered that the browser can be actively and extensively exploited – and that there’s currently no way to stop them. Recent events have shown just how devastating these attacks can be, with critical personal and financial information easily acquired. The scale of fraud, theft, and damage attributable to these client side attacks is shocking and unacceptable. We believe that MirrorTab has created an innovative and effective solution that is unmatched in stopping these hard-to-detect attacks.”
