SASE · Segmentation · Platform conversion

Trust nothing.
Segment everything.

Perimeter One designs, converts, and operates modern network security. We build SASE architectures, enforce zero-trust segmentation, and carry out full conversions from one security platform to another — policy by policy, with a cutover plan you can defend.

Zone: Edge SASE architecture Secure access for every user and site — SSE, ZTNA, and SD-WAN designed as one fabric, not bolted together.
Zone: Internal Network segmentation Zone models and microsegmentation that stop lateral movement without stopping the business.
Zone: Migrate Full platform conversions Complete moves between security platforms — objects, policies, and operations, not just licenses.
Zone: Operate Managed services Your security estate run day-to-day by the engineers who built it — fully managed or co-managed.

Full security platform conversions

Most shops will sell you the new platform. We move you onto it. Perimeter One performs complete conversions between security platforms — legacy firewall estates to next-generation platforms, on-prem stacks to SASE, one vendor's cloud console to another's. We translate every object, policy, and dependency using purpose-built migration tooling, then prove it in staging before anything cuts over.

Assess

Inventory the running config: rules, objects, NAT, routing, and the traffic that actually uses them. Dead rules die here.

Translate

Convert policy to the target platform with our own tooling — deterministic, repeatable, and reviewable line by line.

Stage

Build the target environment in parallel and validate translated policy against real traffic patterns.

Cut over

Move in controlled windows, site by site, with rollback ready at every step. No big-bang weekends.

Operate

Tune, document, and hand off — or stay on as your managed service so the platform never drifts.

Why it works: we write and maintain our own conversion tooling for the platforms we migrate — including PAN-OS and Panorama estates moving to cloud-managed platforms like Strata Cloud Manager and Prisma Access. Automation does the repetitive translation; engineers make the judgment calls.

Zone: Services

Two ways to engage

Project work when you need a change made. Managed services when you need it kept right. Most clients start with one and end up with both.

Professional services

Fixed-scope engagements, engineer-led from first workshop to final runbook.

  • Platform conversions & migrations — firewall, SASE, and cloud security platform moves, end to end.
  • SASE design & deployment — SSE, ZTNA, and SD-WAN architecture built for how your people actually work.
  • Segmentation programs — zone strategy, policy design, and phased enforcement for campus, data center, and OT. Akamai Guardicore is our microsegmentation platform of choice.
  • Security assessments — configuration and architecture reviews with findings you can act on, not a scanner dump.
  • Policy cleanup & rationalization — shrink rulebases, remove shadowed and unused rules, document what remains.

Managed services

Ongoing operation of your network security estate, with real engineers on the other end.

  • Managed firewall & SASE operations — policy changes, upgrades, and health management across your fleet.
  • Policy lifecycle management — every change reviewed, staged, and documented; the rulebase never rots again.
  • Monitoring & response — eyes on your edge and segmentation posture, with escalation paths agreed in advance.
  • Managed WAF — Akamai-based web application and API protection, tuned and watched so real attacks get stopped and real traffic gets through.
  • Co-managed options — your team keeps the keys; we carry the pager and the heavy lifting.
  • Continuous segmentation assurance — verify zones still hold as the network changes underneath them.
Zone: Platforms

Fluent on both sides of the move

A conversion needs deep knowledge of the platform you're leaving as well as the one you're adopting. We work daily across the major network security stacks.

Leaving a platform that isn't listed? If it has a config file, we can read it — our tooling has parsed estates most vendors' own migration tools gave up on.

Zone: Why P1

Built by the engineers who stay

Engineer-led, end to end

The people who scope your project are the people who deliver it. No handoff from sales engineering to a bench you've never met.

Tooling, not heroics

We automate the translation work that burns out project teams, so engineering time goes to design decisions and edge cases — the parts that actually need a human.

Operations-honest design

Because we run these platforms as a managed service, we design them the way they'll actually be operated at 2 a.m. — not the way they demo.
