SASE Deployment Models: Cloud vs. Sovereign SASE Explained

SASE deployment models explained: Cloud SASE vs. Sovereign SASE, and how to place your requirements from Level 1 to Level 5 on the SASE Sovereignty Scale.SASE started as a cloud-delivered security model. Today it comes in deployment models that range from fully cloud to fully on-prem, driven by organizations and governments that need more control over where their data is stored, where security inspection happens, and who operates the infrastructure. This episode compares six SASE deployment models by where the three core components live and who runs them.Key takeaways:• The three core SASE components: the control plane, the data plane, and user data and logs• Level 1, Cloud SASE: the provider runs everything, and remote access from another country can itself count as an international data transfer• Level 2, data residency: logs, telemetry and customer data stay in a region, but data residency is not the same as log residency• Level 3, in-country processing: inspection and data stay in-country, but a third party subject to its home jurisdiction still operates the service• Customer-hosted PoP: local inspection and better performance for large sites, but not a sovereignty control on its own (Level 1 by default)• Level 4, Sovereign SASE with a cloud-managed control plane: inspection and customer data stay on-premises• Level 5, fully self-hosted Sovereign SASE: the control plane moves on-premises too, up to air-gapped deployments• The levels are requirements, not a ranking. Pick a "sovereign enough" model, not automatically Level 5, and weigh who operates it and where it's managed from as heavily as where your data livesChapters:0:00 Intro0:27 Why SASE deployment models evolved1:16 The three core SASE components2:49 Cloud SASE and the SASE Sovereignty Scale3:56 Level 1: Cloud SASE4:54 Level 2: Data residency6:23 Level 3: In-country processing7:48 The customer-hosted PoP9:07 Levels 4 and 5: Sovereign SASE11:03 The full scale: choosing "sovereign enough"12:16 Closing takeawaySources:• Gartner, "How to Choose a Sovereign SASE Deployment Model" (Sep 2026): https://www.gartner.com/en/documents/8395381• DORA, Regulation (EU) 2022/2554, Art. 30: https://eur-lex.europa.eu/eli/reg/2022/2554/ojMore from The CISO Perspective: https://cisoperspective.comWatch the full video: https://www.youtube.com/watch?v=71zTuHOxZuoFollow on X: @CISOPerspectiveKeywords: SASE, SASE deployment models, sovereign SASE, cloud SASE vs sovereign SASE, what is SASE, secure access service edge, data sovereignty, digital sovereignty, data residency, in-country processing, SASE architecture, cybersecurity podcast

Q-Day is the point when quantum computers become powerful enough to break today's encryption.

AI agents now reach your email, files and business apps through the Model Context Protocol (MCP), and Backslash Security found that nearly a third of the most popular MCP servers carried at least one security risk finding. This episode explains how MCP works and walks through the 34 threats the Coalition for Secure AI (CoSAI) lists in its MCP security framework.Key takeaways:• What MCP is: a standard way for AI agents to discover and use tools, either natively or through a separate MCP server• Why connecting an agent to untrusted content opens a new pathway into the corporate environment• Conventional threats (19): weak authentication, excessive privileges, insecure network configuration, poor credential management• MCP-contextualized threats (8): prompt injection, confused deputy, denial of wallet, man-in-the-middle, consent fatigue• MCP-specific threats (7): identity spoofing, tool poisoning, full schema poisoning, resource content poisoning, typosquatting, shadow MCP servers, over-reliance on the LLM• You don't need to reinvent security for AI agents; extend least privilege, strong authentication, segmentation and vulnerability management, and avoid "slop security"Chapters:0:00 Intro: why MCP security matters1:04 What is MCP?2:17 The CoSAI framework3:46 Conventional threats5:34 MCP-contextualized threats7:06 MCP-specific threats8:51 Wrapping up: trust and "slop security"9:17 ClosingSources:• Backslash Security, MCP server security research (Sep 2026): https://www.backslash.security/blog/mcp-server-security-risks-research• CoSAI, Model Context Protocol Security v2.0 (Sep 2026): https://www.coalitionforsecureai.org/wp-content/uploads/2026/09/model-context-protocol-security-v2.0.pdf• Snyk, malicious "postmark-mcp" npm package (Sep 2025): https://snyk.io/blog/malicious-mcp-server-on-npm-postmark-mcp-harvests-emails/Watch the full video: https://youtu.be/iD6oqZV8AlEMore from The CISO Perspective: https://cisoperspective.com

Verizon's 2026 DBIR found the human element in 62% of breaches, and increasingly the browser is where users get tricked into running the attack themselves. This episode compares remote browser isolation (RBI) and the secure enterprise browser: how each works, what problem each solves, and where they fit in SASE.Key takeaways:• How RBI runs risky pages in a disposable cloud browser (pixel streaming vs DOM reconstruction)• Why RBI is applied selectively through a secure web gateway or SASE platform• How a secure enterprise browser puts policy inside the session: copy/paste, uploads, downloads, credentials• Rule of thumb: isolate when the page is the threat; secure the browser when the work is trusted but the user, device or data needs controlChapters:0:00 Intro: the human element and the browser1:07 The two options: RBI vs secure enterprise browsing1:54 How remote browser isolation (RBI) works2:33 Pixel streaming vs DOM reconstruction3:10 Why RBI is applied selectively4:11 How secure enterprise browsing works5:03 Policy controls inside the browser session5:52 So which one do you need?6:25 Where they fit: SASE and Gartner's outlook6:52 The rule of thumbWatch the full video: https://youtu.be/ttmgM_AbkgUMore from The CISO Perspective: https://cisoperspective.com

Security teams can find vulnerabilities faster than ever. The hard part is deciding which exposures actually matter.
