Several of the most notable investors in the cybersecurity scene have lined up behind a secretive Israeli startup called FireGlass Ltd. that is on a mission to change the way organizations defend against hacking. Its site is scrubbed of any details that might give away the trick before the scheduled launch of its offering at the RSA Conference next month, but a seemingly overlooked LinkedIn account provides a glimpse into what attendees can expect to see.

FireGlass claims in its profile description to have developed a new kind of proxy server that does not rely on manually-configured filtering policies to block online threats. Instead, every web page opened by an organization’s workers is automatically redirected to a secure sandbox at the edge of the corporate network, where it’s rendered in isolation. The startup’s service then streams a live feed of the output to the machine at the receiving end of the connection that only lets the visuals through. User input in the browser window is presumably synchronized with the quarantined source to enable interactivity.

FireGlass thereby makes it possible to access sites and web applications without downloading any source-code, which cuts off the main propagation path for online malware. The approach is touted as a more reliable alternative to the conventional whack-a-mole strategy that traditional network protection solutions software take against external threats. It’s also more convenient for security teams, since the absence of active scanners in the startup’s software means there are no false positives to worry about.

That value proposition has already won over several unnamed Fortune 500 companies, according to FireGlass, adoption that the new funding is meant to increase. The round saw the participation of Rakesh Loonkar, a co-founder of IBM Corp.’s Trusteer malware mitigation business, serial cybersecurity entrepreneur Mickey Boodaei and two institutional backers.
