HEAT Shield AI Browser Protection

Menlo Security's HEAT Shield AI protection via a browser extension. HEAT Shield AI with Google Gemini is an advanced phishing and social engineering prevention engine that stops zero-day threats, credential theft, and previously unseen phishing attacks in the browser. We perform AI-based runtime analysis of the entire page—including JavaScript, DOM elements, and URLs—at the point of click. If a threat is detected, dynamic policy controls instantly block the malicious site.

Highly evasive and adaptive threats (HEAT) are a type of cybersecurity threat that often exhibit sophisticated techniques such as dynamic behavior, fileless attacks and delayed execution to avoid detection and evade traditional security measures. These threats are designed to fly under the radar and can be particularly challenging for security professionals to identify and mitigate. Evasive threats have existed for some time as threat actors attempt to increase their success rate of gaining initial access onto a user’s system or into an organization’s network. Even as enterprise security controls continue to evolve, threat actors accelerate their evasive techniques used in an attempt to infiltrate our users and their systems.

Phishing Prevention Powered by Gemini LLM HEAT Shield AI uses the power of AI to perform deep, real-time inspection of webpages. Integrated with Google Gemini, it moves beyond antiquated ML and signature reliance by leveraging powerful multimodal reasoning to analyze both the visual (logos, branding) and structural (URL, page code) elements of a page. This allows HEAT Shield AI to render an instant verdict on whether the page is valid or fraudulent, successfully detecting zero-day phishing and social engineering attacks with a 90%+ success rate. By instantly blocking these sophisticated social engineering attacks and hidden malware before execution, HEAT Shield AI defeats the full spectrum of sophisticated attacks—from zero-day phishing to dynamically hidden malware—that bypass signature-based security tools.
