Absolute Security. Zero Compromise:
The Cloud-delivered Browser Security Solution

The cybersecurity world is defined by Zero-Day exploits and Highly Evasive and Adaptive Threats (HEAT), rendering old "detect and respond" defenses blind. Simultaneously, the explosion of remote work has created unacceptable risk with legacy VPNs and agent-based ZTNA tools, particularly with unmanaged devices. The problem is that nearly all threats—from web links and email to data exfiltration via Gen AI—converge in the browser, making it the single most important place to focus security efforts. Menlo Security solves this with the only Cloud-delivered Browser Security Solution, which completely eliminates risk by executing all content harmlessly in the cloud. This unified approach delivers the only true path to guaranteed zero-day threat prevention, frictionless remote access for all unmanaged devices, and precise data security controls required for safe Generative AI use.

Menlo Stops Threats. Period.

Menlo offers the first and only solution that prevents zero-day exploits and highly evasive threats from ever reaching the endpoint. These protections are more vital than ever, as attackers are increasingly adopting the adversarial use of AI to come up with new or dramatically adapted threats. Using the Menlo Cloud, we execute all web traffic inside a hardened digital twin of the user’s browser in the cloud. We deploy HEAT Shield AI with Google Gemini for advanced generative AI analysis and on-click inspection, stopping even the most sophisticated attacks designed to bypass reputation-based security tools. You get safe, high-fidelity browsing and fully functional, sanitized files, all with no software or infrastructure changes required.

Key Preventative Use Cases:

  • Zero-Day Phishing: Block polymorphic phishing and impersonation sites the moment they appear. Read more.
  • Active Content Risk: Menlo removes all active content in the cloud, ensuring invisible web threats and file-delivered malware never reach your local browser. Read more.
  • Evasive Ransomware: Menlo provides robust malware detection using anti-virus, sandboxing, and hash checks. To ensure zero disruption to file workflows, we add patented Content Disarm and Reconstruction (CDR). This technology sanitizes files automatically while keeping them fully functional, so users can safely download and click without delay.

ZTNA for Managed and Unmanaged Devices

Menlo Secure Application Access (SAA) is a zero trust, cloud-delivered solution providing effortless and safe access for your hybrid workforce.

Menlo SAA is the one solution for managed, unmanaged, and BYOD access, eliminating complexity and risk. Its core function is to act as a protective shield: an unmanaged or compromised device can never infect an enterprise application.

Menlo SAA is easy to deploy, eliminates VPN risks and VDI complexity, and is significantly more cost-effective and cheaper than ZTNA and VDI. It delivers a superior, consistent user experience through any browser, with no client software required, ensuring users are productive and secure.

Key Use Cases:

  • ZTNA for Unmanaged Devices: Provide effortless, identity-based access by treating all devices, including unmanaged ones, as untrusted until validated.
  • VDI Reduction: Simplifies infrastructure and costs by offering a secure, low-complexity alternative to VDI for users on unmanaged personal devices.
  • BYOD Security: Safely grants access to corporate applications from any device, securing unmanaged endpoints and protecting data accessed from high-risk personal devices.
  • VPN Replacement for Managed and Unmanaged Devices: Eliminate VPN vulnerabilities and maintenance headaches, often exploited by attackers compromising unmanaged devices.

Say Yes to Gen AI—Securely

The Gen AI frontier is open. Don't just join the revolution— secure it.

Safe and appropriate use of Gen AI inside the enterprise requires three complementary elements—last-mile DLP with browser context, a method to steer users to sanctioned tools and away from those that are not, and policy monitoring to ensure that policies are working. Menlo has these features built-in.

Menlo Makes Gen AI Security Easy

Menlo has all the tools that you need to minimize the risks of Gen AI use in the browser. With Menlo, you can enable granular access by user and group. You can enable DLP protections inline for all users, including those on BYOD or unmanaged devices. And all from one console.

Easy-To-Use Logging and Forensics

Despite the abundance of network and endpoint security tools, activities that happen in the browser have historically fallen into a blind spot. Security, SOC, and IT teams have had to infer what happened based on the affects of a browsing event downstream. But with Menlo Browsing Forensics, you can see what is happening, in near real time.

As traffic transits the Menlo Cloud, enterprises can quickly view detailed browsing sessions. With Menlo Browsing Forensics, you can choose to record selected browsing sessions, so you can get a near real-time view of how users are interacting with your apps and data, as well as potential phishing sites. This unparalleled visibility slashes incident response time and provides undeniable evidence for compliance and auditing.

Menlo File Security.
All Your Files. None of the Malware.

Current file security tools force a critical trade-off: block workspace productivity to prevent threats, or trust that detection alone will stop malware from entering in the first place. This is unacceptable for modern, file-reliant workflows. For those that can't afford a breach, it's also non-negotiable.

Proactive, Real-time File Security

Menlo File Security delivers defense-in-depth by incorporating next-gen Content Disarm and Reconstruction (CDR), antivirus, hash check, and the ability to sandbox into a single solution that works behind the scenes and seamlessly integrates with current infrastructures. This allows end-users to work as normal while freeing security teams to focus on more important matters.

Zero Trust Equals Zero File-borne Breaches
We go beyond traditional CDR tools. Rather than scan for known threats, our patented Positive Selection® technology assumes all files are malicious, immediately detecting, dissecting, and reconstructing a new, clean file using only components guaranteed to be safe. This process eliminates evasive malware, ransomware, and zero-day file exploits (even those hidden in archives or password-protected files) while ensuring the final document retains its formatting and functionality (i.e., macros). With Menlo, both internal and third-party users can safely click, download, upload, and share without delay.

5 hexagons with key industries Menlo protects
"Highly evasive threats are growing as threat actors evolve how they deploy phishing and malware attacks. Tools like Menlo Security’s browser security solution, including their HEAT Shield, can help to combat cyber threat vectors for the world’s top financial institutions, governments and leading enterprises."
"Menlo Security is the easiest way for us to analyze malicious URLs and combat HEAT (Highly Evasive Adaptive Threats) as we conduct our investigations and research. It has been a good solution for us when it comes to our incident response especially as we investigate hundreds of threats every day. With Menlo, we can easily detect malicious URLs leading to faster threat detection response. Menlo allows us to provide our analysts with a risk-free internet experience without impacting user performance."
"Menlo gives us full visibility inside the browser allowing me to detect and block highly evasive threats targeting my users. Before Menlo Security we didn’t know our users were being targeted with evasive web threats until it was too late. Menlo Security now provides us with visibility into the browser allowing us to completely remove the malware problem from web and email links. Menlo allows us to provide users with a risk-free internet experience without impacting user performance."
"Menlo gives us full visibility inside the browser, allowing me to detect and block highly evasive threats targeting my users."
"We know we need to protect our network from emerging attacks and threats targeting the web browser. We are seeing highly evasive threats as a concerning and growing tactic amongst threat actors, and solutions like HEAT Shield can dynamically block these attacks, even if they are zero hour, keeping our endpoints safe."
"The solution prevents all web and email security threats before they enter our network. The main difference with the on-premise proxy was that we were heavily dependent on signatures, web categorization, and filtering. We have seen a decrease in the number of security alerts that our security ops team has to follow up on. Menlo provides a periodic report, which we can check on a regular basis. The report gives me confidence that the websites that are supposed to be blocked are always blocked. It lessens the tasks of the personnel who are doing web monitoring, so they're able to do other things."
"Menlo provides my users a risk-free internet experience with no noticeable difference to their browsing speed."
