Palo Alto Networks

The multi-tenant firewall platform that succeeded Juniper at the City, carried through twenty-six design revisions across six independently governed agencies.

Product lines and other names: PA-5260, Panorama, GlobalProtect, Prisma

Left to right is time. Each row is one of the 15 disciplines Palo Alto Networks carried, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that named this manufacturer is counted, so this is the shape of what it carried rather than of the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

PA-5260 and PA-5260S at the core, with PA-5250, PA-5420, PA-3430 and PA-3430S in the estate and PA-220 units for small tenants and test. Managed through Panorama, remote access on GlobalProtect, content control on Advanced URL Filtering.

Migrated from the Juniper SRX estate in 2021, and the design ran to twenty-six revisions because six agencies with separate legal obligations shared one platform and every pair of zones was a deliberate decision. Palo Alto asked to publish it as a white paper; it was declined as public-safety facing.

On the consulting side it appears again as the multi-site refresh met by an intrusion the night after cutover, and as Prisma on one SD-WAN engagement.

Where it appears

Declared on each entry rather than listed here, so this page cannot drift from the work it describes. What each entry named is quoted as it stands, with how much of that project rested on it and what stands behind the claim beside it. The first of those drives the height of the surface above.
