Guardicore

Founded in 2013 in Tel Aviv by Pavel Gurvich and Ariel Zeitlin. Their thesis was that the classic perimeter firewall had become pointless: once inside the network, an attacker can move laterally between servers at will. Guardicore deploys lightweight agents that map every flow and let you deny all but what's explicitly allowed — zero trust applied to east–west traffic.

The map view, showing application dependencies as a living graph, was what people remembered best. Akamai bought the company in 2021 for around $600 million to pair its edge platform with segmentation on the inside, and rebranded it Akamai Guardicore Segmentation.
