A practical, step-by-step migration plan for IT admins to replace Chrome with a privacy-first or local-AI browser like Puma, covering policy, extensions, and deployment.

Stop chasing Chrome updates—start owning your browser strategy

IT teams in 2026 face escalating demands: tighten privacy, reduce vendor telemetry, support local-AI capabilities, and keep developers productive with stable extension ecosystems. If your enterprise still depends on Google Chrome as the default without a migration plan, you're carrying technical debt that affects security, compliance, and developer velocity. This guide is a pragmatic, step-by-step migration plan for replacing Chrome with a privacy-first or local-AI browser (for example, Puma) in enterprise environments—covering policy mapping, extension compatibility, deployment automation, and training.

Executive summary — what you'll get

Actionable migration roadmap broken into assessment, pilot, deploy, and scale phases.
Policy-parity approach: how to map Chrome policies to alternatives (ADMX, MDM/Intune JSON).
Extension strategy: compatibility testing matrix, remediation options, and CI/CD for extensions.
Deployment patterns for Windows/macOS/Linux and mobile (iOS/Android).
Operational and training plans for helpdesk, developers and security teams.

The 2026 context: why now?

Recent trends make Chrome replacement a strategic initiative, not just a curiosity:

Local-AI browsers (eg. Puma) matured in 2025–26; on-device LLMs let organizations apply generative features without moving data to third-party clouds.
Privacy and regulation increased—EU and state-level frameworks that expanded in late 2025 tightened telemetry and profiling rules, putting spotlight on browsers that embed cloud analytics.
Enterprise tooling now supports alternative browser management through ADMX, MDM, and APIs—removal of Chromium lock-in is practical.
Security architecture shifts—Zero Trust and browser isolation integrate better with privacy-first clients, enabling safer hybrid work without sending all content to cloud filtering providers.

Core migration principles

Policy parity over feature parity: map security and compliance policies first—cookie, certificate handling, SSO, proxy, extension control. See our notes on policy and auditability patterns for policy-as-code ideas.
Progressive rollout: pilot teams by risk profile (R&D first, finance last).
Extension governance: treat extensions like code—scan, test, and stage through CI pipelines. Use developer playbooks for extension lifecycle management (see developer experience guidance).
Observability and rollback: deploy telemetry (privacy-preserving) and automatic rollback for critical issues.

Step 0 — Pre-migration assessment (2–4 weeks)

Inventory endpoints: use SCCM/Intune/endpoint agents to list installed browsers, extensions, and User Agent-dependent apps. A tool-sprawl audit approach helps here.
Extension inventory: capture a per-user list of extensions and annotate business value, publisher, and permissions (network, filesystem, nativeMessaging).
Policy baseline: export Chrome/Edge policies (ADMX, registry keys, MDM profiles). Document which are critical (SSO, cert pinning, CSP enforcement).
Compatibility scan: identify intranet apps and web apps (SaaS) that require Chrome-specific features (plugins, old NPAPI, UA sniffing).
Risk map: group teams into Low/Medium/High risk for pilot selection.

Tools and commands

Quick command to export installed extensions on Windows (PowerShell):

Get-ChildItem "$env:LOCALAPPDATA\Google\Chrome\User Data\Default\Extensions" -Directory | Select-Object Name

Use Playwright to test a list of internal URLs for rendering and critical flows (login, forms):

npx playwright install && node ./scripts/checkUrls.js

Step 1 — Choose the replacement and validate it

Select a browser that meets your privacy and local-AI requirements. Puma is an example: a browser that embeds local LLMs, emphasizes on-device processing, and publishes management interfaces. Checklist:

Supports enterprise management (ADMX/MDM/remote config).
Implements the WebExtensions API subset used by your critical extensions.
Has a robust update mechanism and offline installation packages (MSI, PKG, DEB/RPM).
Provides telemetry controls and clear privacy documentation — consider operational consent and logging guidance from the consent playbook.

Policy mapping

Create a policy matrix: list every Chrome policy you use and the equivalent in the replacement. Example mapping table (conceptual):

Chrome: AutoLaunchProtocols -> NewBrowser: ProtocolHandlers
Chrome: ExtensionInstallForcelist -> NewBrowser: ForceInstallExtensions
Chrome: SafeBrowsingEnabled -> NewBrowser: SafeBrowsing (or align with network isolation)

If the replacement lacks one-to-one mappings, plan compensating controls (proxy-level enforcement, CSP headers, or extension whitelisting in a gateway).

Step 2 — Extension compatibility strategy

Extensions are often the biggest blocker. Use this pragmatic approach:

Classify extensions: business-critical, helpful, personal.
Test compatibility: run each critical extension in a controlled environment and log failures or missing APIs.
Remediate:
- For WebExtensions-compatible extensions: use enterprise sideloading or a curated extension store.
- For native messaging or deprecated APIs: build a small shim or internal extension replacement. Consider converting to a content script + hosted backend where allowed by policy.
- For proprietary enterprise extensions: repackage and sign for the new browser; set up CI to rebuild and test.
Approve and stage: add tested extensions to a curated catalog and push to pilot groups.

CI/CD for extensions

Treat extensions like apps—use a pipeline that lints, builds, tests (Playwright), signs, and publishes to your internal gallery. Example steps:

Pre-commit hooks: eslint + manifest validator.
CI: run unit tests, Playwright UI tests, and a compatibility suite against the target browser.
CD: package and upload to internal extension repository or create a signed .crx/.xpi equivalent supported by the new browser.

Step 3 — Pilot (4–8 weeks)

Run a time-boxed pilot with 50–300 users depending on org size. Goals: validate policies, extension behavior, SSO, and performance.

Deploy via Intune (Win32), SCCM, Jamf (macOS), or apt/rpm for Linux.
Enforce policies using ADMX import or MDM profiles. For non-AD environments, use a configuration-management agent to apply JSON policies.
Monitor via privacy-preserving logs: crash rates, extension failures, login issues, and support tickets.
Collect feedback from pilot groups and maintain a public issue board for transparency.

Sample Intune JSON policy (concept)

{
  "@odata.type": "#microsoft.graph.deviceConfiguration",
  "displayName": "Puma Browser - Managed Settings",
  "omaSettings": [
    {
      "displayName": "Disable telemetry",
      "omaUri": "./Vendor/MSFT/Policy/Config/Browser/Telemetry",
      "value": "0"
    }
  ]
}

Step 4 — Deploy and automate

Once the pilot stabilizes, expand in phases. Key deployment patterns:

Windows: MSI or Intune Win32 packages, use Group Policy ADMX templates to lock down settings.
macOS: Signed PKG with Jamf profiles; use configuration profiles for preferences.
Linux: DEB/RPM plus configuration management (Ansible, Salt) to push JSON policy files and extension catalogs.
Mobile: iOS/Android managed app deployment via MDM; push local-AI models on devices where allowed.

Automating default browser and data migration

Use scripts to set the default browser and migrate bookmarks/passwords. Example PowerShell to set default via Windows 10+ protocol defaults (requires a file association XML):

# Export current associations for reference
Dism /Online /Export-DefaultAppAssociations:"C:\temp\current.xml"
# Import new associations
Dism /Online /Import-DefaultAppAssociations:"C:\deploy\puma_associations.xml"

For scripting patterns and deployment automation, treat defaults and associations as part of your deployment automation toolkit.

Step 5 — Operations: monitoring, hardening, and integration

After you deploy enterprise-wide, shift to operational excellence:

Security hardening: enforce CSP headers for internal apps, enable strict transport security, and integrate with corporate CASB/SSE for DLP and isolation where needed.
SIEM integration: collect privacy-respecting telemetry (failed extensions, crashes, policy non-compliance) and feed to Splunk/Datadog.
Patch automation: ensure browser auto-updates are enforced, or manage via your update catalog—critical for zero-day mitigation.
Model lifecycle: if using local AI, manage model updates (on-device model packs), vet model provenance, and sign model artifacts. See patterns for internal model delivery with internal developer assistants.

Training and change management

Adoption fails without training. Organize a tiered training plan:

IT & Security (1–2 days): admin guides, policy mapping, troubleshooting, and rollback playbooks.
Developers & DevOps (half-day): extension dev standards, local debugging, and Playwright/Selenium test updates to target the new browser.
Helpdesk (1 day): common ticket triage, scripted fixes, and escalation process.
All users (30–60 min): highlight productivity features, privacy benefits, bookmark migration instructions, and self-help guides.

Provide bite-sized documentation: quick-start videos (2–3 min), a searchable FAQ, and an internal Slack/Teams channel for migration updates. Consider pairing training with your internal learning and adoption platform for tracked rollouts.

Measure success — KPIs to track

Reduction in telemetry/third-party network calls (privacy metric).
Support tickets per 1,000 users during rollout phases.
Critical extension compatibility rate (target >95% for business-critical set).
Time-to-first-fix for login or SSO issues (target <2 hours for critical users).
Adoption rate and retention after 90 days.

Common pitfalls and how to avoid them

Neglecting legacy intranet apps: test early, and build shims (UA negotiation or small compatibility proxies) where rewriting isn't feasible.
Underestimating extension churn: set up a small extension engineering team or vendor contracts for timely compatibility updates.
Skipping pilot diversity: include remote/mobile heavy users and power devs to catch edge cases.
Overly strict policy at rollout: start with permissive policies that log first, then tighten based on real-world telemetry.

Case example — Mid-sized fintech (realistic composite)

In late 2025, a 1,200-seat fintech replaced Chrome with a local-AI-first browser for compliance with a new EU privacy standard and to reduce cloud exposure. Key moves that worked:

Three-week assessment found 28 critical extensions—20 were WebExtensions compatible; 8 required native messaging shims.
Pilot included devs and customer support. Playwright tests simulated cash transfer flows; two failures triggered rapid policy adjustment for cookie handling.
They built an extension CI pipeline; patches for legacy extensions were delivered within two sprints.
Outcome: reduced telemetry to third-party clouds by 72% and cut average login incidents by 40% thanks to tighter SSO controls.

Future-proofing: where browser tech is headed

Expect these trends through 2026–2028:

On-device AI primitives will become a common differentiator—plan for model management.
Policy-as-code will replace manual Group Policy modifications—invest in declarative tooling and testing for policies. See edge auditability patterns.
Better extension governance tools will appear: supply-chain scanning, signed manifests, and enterprise extension stores will become standard.
Browser security integration with SASE and ZTNA will deepen—expect centralized orchestration APIs.

Practical rule: treat the browser as an enterprise platform—not just an application. Manage it with the same rigor you manage servers and CI pipelines.

Actionable checklist (first 90 days)

Inventory browsers & extensions (Week 1–2).
Create policy mapping and a compatibility matrix (Week 2–3).
Run a small pilot and validate SSO, proxy, and extensions (Weeks 4–8).
Automate packaging & CI/CD for extension governance (Weeks 6–10).
Deploy phased rollout, integrate telemetry into SIEM, and run staff training (Weeks 10–12).

Closing: risk-managed Chrome replacement is achievable

Replacing Chrome in an enterprise is a non-trivial program, but with a policy-first approach, disciplined extension governance, and automation for deployment and monitoring, you can move to a privacy-first or local-AI browser without disrupting productivity. The benefits in 2026 are tangible: lower telemetry risk, better regulatory alignment, and local-AI features that improve developer workflows while keeping data on-device.

Actionable takeaways

Start with policy parity and extension inventory—these are the high-risk areas.
Run automated compatibility tests (Playwright/Selenium) as part of your CI for extensions and web apps.
Use MDM/ADMX policies and declarative config-as-code for reproducible deployments.
Train helpdesk and developers early to surface issues fast and keep adoption momentum.
