Malware Isolation Firm Menlo Security Raises $40 Million

Menlo Security, a provider of malware isolation technology, announced on Monday that it has closed a $40 million Series C funding round, bringing the total amount raised by the company to $85 million. 

The Menlo Park, Calif.-based company pushes the fact that its offerings do not provide malware detection or classification. Instead, the company’s cloud-based security platform takes all active content—including potentially malicious files—and executes it in the cloud, giving malware no path to reach an endpoint via compromised or malicious web sites, e-mail, or documents. 

“Rather than try to distinguish between safe and risky content, the Menlo Security Isolation Platform acts like a digital partition, isolating and executing all web content, email links and documents in the cloud, then streaming a malware-free version of the content to employees’ computers,” the company explains. 

Menlo says the additional funding will help support sales and marketing efforts.

American Express Ventures, Ericsson Ventures and HSBC, participated in the funding round as new investors. They join existing investors JPMorgan Chase, General Catalyst, Sutter Hill Ventures, Osage University Partners and Engineering Capital.
