Zscaler → Cloudflare One
From ZIA (SWG), through Discover → Map users → Pilot wave → Cutover, into the Cloudflare destinations on the right.
On this page
Nanosek helps security and network teams compare Zscaler policy models with Cloudflare One, then migrate users, applications, tunnels, device posture, and traffic steering in phases.
Who this is for
Problems solved
- Legacy rules and platform behavior are difficult to translate safely.
- Cutover windows require rollback planning, stakeholder alignment, and live validation.
- Security controls need tuning before they can move from monitoring to enforcement.
- Operations teams need logging, ownership, and change control after launch.
Delivery approach
Discovery of current architecture, traffic patterns, domains, rules, identities, integrations, and operational constraints.
Mapping of existing controls into Cloudflare primitives with clear decisions for keep, replace, simplify, or retire.
Staged implementation using test zones, shadow logging, monitor mode, canary traffic, and documented approval gates.
Post-cutover tuning, dashboarding, incident workflow alignment, and managed operations handoff.
Architecture
Migration steps
- 01 Assess the existing environment and define success criteria.
- 02 Create a Cloudflare target architecture and migration backlog.
- 03 Build and test controls in monitoring or non-production mode.
- 04 Run stakeholder validation and prepare rollback procedures.
- 05 Execute phased cutover with live monitoring.
- 06 Tune enforcement and transition to managed operations.
Risks and mitigations
False positives during WAF or bot enforcement.
Start in logging or simulate mode, review traffic, and promote controls gradually.
DNS or certificate disruption during cutover.
Lower TTLs, validate records, preload certificates, and keep rollback instructions ready.
Missing visibility after migration.
Configure Logpush, dashboards, alerts, and operational ownership before launch.
Behavior differences between legacy vendor and Cloudflare.
Use mapping workshops, test cases, and canary validation before full traffic shift.
