Menlo Security Overview

Menlo Security has been around since 2012, based out of Mountain View, California. Their entire company mission is built on a simple but powerful idea: preventing cyberattacks.

From my analysis, they primarily serve large enterprises in high-stakes industries like finance and government. What really makes them different is their singular focus on proactive prevention, using a patented, air-gapped isolation technology.

With a recent Series E funding round and new generative AI integrations, they are clearly investing heavily. You can see the impact of this throughout this Menlo Security review.

While competitors like Zscaler offer broader platforms, I find Menlo is obsessed with its core mission: preventing 100% of malware from the web. This unique “isolate-or-block” philosophy provides a much stronger guarantee.

They work with major global corporations, financial institutions, and government agencies—organizations that require a truly preventative security model because they simply cannot afford any potential security breach.

Their current business strategy is completely centered on leveraging their Isolation Core™ for every threat vector. It’s a pure Zero Trust model that directly answers your need for proactive defense against modern threats.

Now let’s examine their capabilities.

Menlo Security Features

Worried about sophisticated cyber threats slipping through?

Menlo Security features an integrated suite built on its Isolation Core™ that redefines your organization’s security posture. Here are the five main Menlo Security features that offer a truly preventative approach.

1. Remote Browser Isolation (RBI)

Tired of web-borne threats reaching your devices?

Evasive malware and zero-day phishing attacks can bypass traditional defenses, creating constant vulnerability for your users. This can lead to costly breaches.

RBI runs all web content in a secure cloud container, delivering only safe, mirrored content to your browser. From my testing, the seamless browsing experience is remarkable, making it almost impossible for threats to reach your endpoint. This feature creates an “air gap” between the internet and your device.

This means you can browse the web without fear, drastically reducing your attack surface and protecting against unknown threats.

2. Secure Web Gateway (SWG)

Is your web security struggling to keep up with modern threats?

Outdated web gateways often rely on detection after the fact, leaving a window open for new threats to slip through. This creates a reactive security posture.

Menlo Security’s SWG, powered by isolation, proactively blocks malicious content rather than just detecting it. What I found impressive is its ability to scale globally without on-premises appliances, simplifying deployment. This feature consolidates URL filtering, threat protection, and DLP.

So, your team gets consistent, proactive web protection, no matter where they are or how they connect to the internet.

3. Secure Email Gateway (SEG) / Email Isolation

Are malicious email links still a top concern for your team?

Email remains a primary attack vector, with phishing and malware-laden attachments posing constant risks. This leaves your employees vulnerable to costly incidents.

This feature isolates suspicious email links and attachments, executing them in a safe cloud environment or read-only mode. From my evaluation, its unique ability to protect against zero-day phishing embedded in emails is a game-changer. This ensures no malicious code ever touches your device.

What you get is unparalleled protection against the most common cyber threats, keeping your inbox clean and secure.

4. Data Loss Prevention (DLP)

Struggling to prevent sensitive data from leaving your network?

Traditional DLP tools can miss data exfiltration attempts, especially with evolving web applications and user behaviors. This puts your critical data at risk.

Menlo Security’s DLP provides comprehensive control over data flows by inspecting all web uploads and user input, even in isolated sessions. This is where Menlo Security shines, offering perfect visibility to detect subtle data exfiltration techniques. It includes over 300 built-in data type dictionaries.

This means you can confidently protect sensitive information from unauthorized leaks, maintaining compliance and securing your intellectual property.

5. Secure Application Access / Zero Trust Access

Is remote access still a security headache for your organization?

Relying on traditional VPNs or VDI for remote access can introduce vulnerabilities and management complexities. This limits flexibility for your hybrid workforce.

This feature offers a Zero Trust approach, granting least-privileged access to SaaS and private applications by executing content remotely. Here’s the thing – it eliminates the need for VPNs and VDIs entirely, enhancing security and simplifying access. Granular controls like read-only policies are also available.

So, your remote teams get secure, seamless access to critical applications without compromising your network or requiring complex infrastructure.

You’ll appreciate how these Menlo Security features work together to create a unified, prevention-first security platform, protecting you from modern cyber threats.
