The platform retains Umbrella's DNS-layer security while adding zero trust network access, data loss prevention, digital experience monitoring powered by ThousandEyes, firewall as a service, and controls for generative AI applications and autonomous AI agents. ### Source excerpt For years, Cisco Umbrella has been the industry gold standard for DNS-layer security. By blocking threats before a connection is even established, it provides IT teams with a critical first line of defense and the visibility needed to keep networks safe. However, the threat landscape has changed. With the rise of hybrid work, the proliferation [...] The post Securing the Modern Workforce: The Evolution of Cisco Umbrella appeared first on Cisco Umbrella. ## Zero Trust Architecture: From Perimeter Walls to "Never Trust, Always Verify" DevFeed: [Zero Trust Architecture: From Perimeter Walls to "Never Trust, Always Verify"]() Original publisher: [Read original article]() Author: hello@ankit-rana.com Published: 2026-03-16T00:00:00Z Content type: tutorial Language: en Sources: [Ankit Rana | Mechanical Sympathy]() Topics: [Zero Trust](), [Architecture & Design](), [Encryption](), [least privilege](), [zero trust network access](), [Authentication](), [Authorization](), [Monitoring](), [Network]() Tags: [architecture](), [authentication](), [cloud](), [encryption](), [identity-and-access](), [least-privilege](), [monitoring](), [network](), [network-security](), [observability](), [security](), [security-architecture](), [zero-trust](), [zero-trust-network-access](), [ztna]() ### AI overview This article explains Zero Trust Architecture as a security model that assumes the network may already be compromised. 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. Its functionality has been incorporated into the Umbrella Roaming Module in Cisco Secure Client, which can migrate existing settings and adds features including Secure Web Gateway protection and improved interoperability with third-party VPNs. ### Source excerpt The Cisco Umbrella Roaming Client has long provided DNS security for millions of Umbrella users. In response to customer feedback, and as Negisa Taymourian covered in her blog post last month, we've introduced a more advanced client: Cisco Secure Client -- our next-gen endpoint agent that goes beyond VPN. Cisco Secure Client offers multi-function capability, [...] The post Millions of Cisco Umbrella Roaming Client Users to Benefit From Upgrading to Cisco Secure Client appeared first on Cisco Umbrella. ## Is VPN or Zero Trust Access Best for Remote Working Security? DevFeed: [Is VPN or Zero Trust Access Best for Remote Working Security?]() Original publisher: [Read original article]() Author: info@goteleport.com (Sheekha Singh) Published: 2022-06-07T00:00:00Z Content type: comparison Language: en Sources: [Teleport]() Topics: [zero trust network access](), [Virtual Private Network](), [Zero Trust](), [Security](), [remote access](), [ZTNA]() Tags: [remote-access](), [security](), [vpn](), [zero-trust](), [zero-trust-network-access](), [ztna]() ### AI overview This article compares VPN-based remote access with Zero Trust Network Access for remote working security. It describes VPN benefits and limitations, including broad network access, weaker granularity, slower connections as usage grows, and management complexity, then introduces zero trust as an alternative and outlines the transition to a zero-trust architecture. ### Source excerpt This article will explore how zero trust access is a better alternative than a VPN for remote working.
