Previous approaches towards web and email security sought to stop attacks outright. The idea was to identify every risky transaction and stop it in its tracks. This approach is increasingly being seen as untenable, as the sheer number of attack vectors increases.
An approach with growing promise is one that lets attacks occur but isolates the content so that the attack cannot cause extended harm. Essentially, it says to attackers “do your worst,” secure in the knowledge that their worst will only harm a specific and contained area.
Menlo Security is one vendor trying this approach. Menlo offers an “Isolation Platform” that works by isolating all web content on the cloud, away from a user’s machine. Users interact with websites, links, and documents on the cloud, without compromising the security of their physical devices or on-premises equipment.
