SASE · Segmentation · Platform conversion

Trust nothing.
Segment everything.

Perimeter One plans and operates network security change: SASE deployments, segmentation programs, firewall policy, and migrations between security platforms. Each engagement starts with the current environment and ends with a tested cutover or operating plan.

Zone: Edge SASE architecture Plan access for users, sites, and private applications across SSE, ZTNA, and SD-WAN.
Zone: Internal Network segmentation Build zone models and workload controls around known application dependencies.
Zone: Migrate Full platform conversions Move objects, rules, NAT, routing, logging, and operating procedures—not only licenses.
Zone: Operate Managed services Day-to-day policy, platform health, upgrades, and change work in managed or co-managed form.

Full security platform conversions

A platform decision is only the start. A usable migration also accounts for policy intent, NAT, routing, VPNs, logging, identity, operating procedures, and rollback. We inventory those dependencies, translate what belongs in the target, and test before cutover.

Assess

Inventory rules, objects, NAT, routing, VPNs, logging, and the traffic that uses them.

Translate

Translate policy with repeatable tooling and record the decisions that require engineering judgment.

Stage

Build the target environment in parallel where practical and validate representative traffic.

Cut over

Move in controlled phases with owners, acceptance checks, and a rollback procedure.

Operate

Tune, document, and hand off the platform, or continue under a defined managed-service scope.

The governing idea: automate repeatable translation, keep policy intent reviewable, and require a human decision wherever the source and target models do not match.

Zone: Services

Two ways to engage

Use a fixed-scope project for a defined change, or a managed service for recurring operational work. The responsibilities and approval boundary are written down before work starts.

Professional services

Defined engagements from discovery through validation and handoff.

  • Platform conversions & migrations — firewall, SASE, and cloud security platform moves, end to end.
  • SASE design & deployment — SSE, ZTNA, and SD-WAN architecture based on user, site, and application requirements.
  • Segmentation programs — zone strategy, policy design, and phased enforcement for campus, data center, and OT, including host-based microsegmentation where required.
  • Security assessments — configuration and architecture reviews with prioritized findings and evidence.
  • Policy cleanup & rationalization — shrink rulebases, remove shadowed and unused rules, document what remains.

Managed services

Ongoing operation of network security platforms under a documented responsibility model.

  • Managed firewall & SASE operations — policy changes, upgrades, and health management across your fleet.
  • Policy lifecycle management — review, stage, document, and periodically recertify rules.
  • Monitoring & response — eyes on your edge and segmentation posture, with escalation paths agreed in advance.
  • Managed WAF — Akamai-based web application and API policy, monitoring, and change management.
  • Co-managed options — shared access and approval boundaries tailored to the customer team.
  • Continuous segmentation assurance — verify zones still hold as the network changes underneath them.
Zone: Platforms

Platforms in scope

Migration planning has to account for the source and target platforms. These are the current areas of focus for Perimeter One services.

Palo Alto Networks Prisma Access Strata Cloud Manager Panorama Zscaler Fortinet Cisco / Meraki Check Point Sophos Juniper Netskope Aruba / HPE Akamai Guardicore Akamai

A platform not listed here needs a discovery review before scope, schedule, or conversion coverage can be confirmed.

Zone: Why P1

A practical operating model

Named ownership

Every engagement has a clear technical owner, approval path, and escalation route.

Repeatable translation

Automation handles consistent transformations; engineers review exceptions and document decisions.

Designed for operations

Runbooks, monitoring, access, maintenance, failure behavior, and rollback are part of the design.
