It contrasts Zero Trust with perimeter security and describes explicit verification, contextual authorization, least privilege, encryption, segmentation, and continuous monitoring. It also distinguishes the broader ZTA model from Zero Trust Network Access (ZTNA). ### Source excerpt Zero Trust starts from the assumption that the network is already compromised, so every request is authenticated, authorised, and encrypted regardless of where it originates. It rests on explicit verification, least privilege, micro-segmentation, continuous monitoring, and encryption everywhere. It is an architectural direction, not a product you buy. ## Cisco Umbrella Roaming Client End of Support Set for April 2025; Cisco Secure Client Offers a Migration Path DevFeed: [Cisco Umbrella Roaming Client End of Support Set for April 2025; Cisco Secure Client Offers a Migration Path]() Original publisher: [Read original article]() Author: Adam Winn Published: 2024-03-19T08:00:00Z Content type: article Language: en Sources: [OpenDNS]() Topics: [Cisco](), [Security](), [upgrade](), [Cloud](), [Virtual Private Network]() Tags: [agent](), [blog](), [blog-post](), [cisco](), [cisco-secure-client](), [cisco-secure-endpoint](), [cloud](), [compatibility](), [configuration](), [dns](), [dns-security](), [end-of-life](), [interoperability](), [network](), [product](), [products-services](), [secure-web-gateway](), [support](), [swg](), [umbrella-roaming-client](), [upgrade](), [vpn](), [zero-trust-network-access](), [ztna]() ### AI overview Cisco says the stand-alone Umbrella Roaming Client will reach end of support in April 2025.
