What if the tools you trust most are the very thing attackers can easily bypass? Evasive ransomware is escalating because it exploits the fundamental weakness of your security architecture:
Detect-and-Respond based tools like EDR and EPP are easily bypassed by new, polymorphic malware that lack known signatures. Attackers use sophisticated tactics, like HTML smuggling and password-protected files, as an initial access technique, in order to successfully deliver malicious payloads to the endpoint, bypassing traditional content filters. When this sophisticated ransomware succeeds, the consequences are immediate:
Enterprises that prioritize stopping ransomware deploy cloud-based browser security—the only solution architected for zero-day threat prevention—to eliminate browser risk where traditional detect-and-respond tools fail.
Menlo's proactive defense directly addresses the browser security gap of traditional security vendors by fundamentally eliminating the threat, rather than waiting to detect it. While network and endpoint security tools remain critical to endpoint hygiene, they are blind to zero-day threats and polymorphic malware. Menlo augments these tools by stopping threats in the cloud—before they ever reach the device or penetrate the network perimeter. Menlo provides a full suite of threat prevention capabilities designed to help enterprises defend against today's most sophisticated malware and ransomware attacks, including:
This unified platform delivers guaranteed prevention, moving you beyond the limitations of slow, signature-based defense.
Menlo executes all web traffic and content in a hardened digital twin of the user's local browser in the cloud. This completely separates the user's endpoint from the public web, preventing 100% of web-borne malware, ransomware, and the initial breach required for double extortion from ever reaching the device.

Menlo File Security proactively assumes all files are hostile. It strips out all active, executable content—including evasive code in password-protected files and nested archives—and reconstructs a 100% safe, fully functional file. This eliminates the risk of file-borne ransomware.

Menlo HEAT Shield AI, with the advanced generative AI analysis of Google Gemini, uses advanced machine learning and computer vision to instantly detect and dynamically block highly evasive threats (HEAT) and zero-day phishing attacks. By eliminating this initial access point, the solution cuts off the attacker's path to a successful ransomware breach that traditional EDR/EPP tools miss.

Stop the ransomware attack chain before it starts, eliminating initial access and ending double extortion threats where traditional security tools fall short.
The Menlo Cloud executes all web traffic—including malicious code and client-side exploits—in a hardened digital twin of the user's browser in the cloud. This proactive isolation architecture physically separates the user from the attack, instantly neutralizing common vectors like zero-day phishing and HTML smuggling where EDR tools are blind. Crucially, this platform delivers guaranteed security enhanced by Menlo's HEAT Shield AI and Google Gemini's high efficacy models, achieving an unparalleled 90%+ detection rate of true zero-day attacks to effectively shut down the initial access point for ransomware and other advanced threats.

Menlo is client-free and requires no software installation, allowing your hybrid workforce to use any browser or device (managed or unmanaged) without interruption or performance latency. By securing the session in the Menlo Cloud before it reaches the endpoint, we eliminate the primary risk vector from unmanaged devices and guarantee a seamless, zero-friction experience that protects users from initial compromise without sacrificing productivity.

Menlo Security delivers the industry's only Cloud-delivered Ransomware Prevention that works right out of the box, offering unmatched protection without unnecessary complexity. By leveraging the full suite of protection capabilities, Menlo immediately eliminates the most common ransomware initial access vectors—including web, email, and files—before they ever reach the endpoint. Because the solution is agentless and requires zero configuration, deployment is quick and effortless. You gain guaranteed, high-efficacy ransomware defense with immediate time-to-value and none of the administrative overhead or performance lag associated with legacy detection tools.

The most dangerous malware starts in the browser. Menlo Security is the first and only solution to eliminate the ransomware risk gap.

Large enterprises struggle to patch thousands of endpoints quickly, leaving critical vulnerability windows open across unsynchronized devices. Menlo instantly removes this exposure, regardless of patch status, by executing web content in a secure cloud environment. Patch cloud browsers once and instantly secure every user on your network.
Menlo Cloud executes every web request in the cloud to guarantee a clean content experience. We provide comprehensive inspection, including antivirus, sandboxing, and file-handling for all content, even password-protected files.
Like all Menlo technology, files are assumed to be malicious; nothing gets a “free pass.” Menlo uses patented Positive Selection® technology to disarm and reconstruct all files to deliver clean, safe content that is fully functional and retains its original format.
Answers to the burning questions in your mind.
Ransomware isn't the start of the problem; it's the final consequence of a successful breach. The true risk lies in the initial stages of the attack, often carried out by evasive browser malware. Traditional detection-based tools fail against new zero-day threats because they're reactive, relying on past signatures and IoCs. Known-safe sites are still allowed to run locally, creating a massive exposure window for zero-day and highly evasive malware hosted on trusted domains. Menlo takes a proactive approach: we inspect all web traffic and content before it reaches the endpoint to block evasive malware and zero-hour phishing, focusing on eliminating 'Business Risk' completely.
Menlo Cloud uses next-gen Content Disarm and Reconstruction (CDR) capabilities to treat all files as malicious until proven safe. It strips all active, executable content from the download and reconstructs a clean, safe, and fully functional file for the end user.
Menlo delivers the first and only proactive solution against zero-day threats and evasive ransomware that works with any browser, requiring no endpoint software. Menlo Cloud architecture eliminates the reliance on signature updates and EDR patching, simultaneously closing the zero-day gap for all users—managed and BYOD—while significantly reducing SOC alert fatigue.
