"Port security" is not one industry, and a guide that pretended otherwise would mislead. In practice the work divides three ways, and this guide is organised on exactly that division. The specialists — Ambrey, Dryad, ICTS and their peers — sell security as a service: embarked teams, facility guarding, intelligence. The terminal operators — APM Terminals, DP World, PSA, ICTSI — mostly do not buy it at all: they run security in-house, to the ISPS Code, as a department of the terminal. And the screening majors — Smiths Detection, Rapiscan, Leidos — build the machines that see inside the box. A reader who understands those three models understands the field.

One honest structural note: the specialists almost never name their clients, and several publish no revenue at all. Where this guide cannot verify a figure or a name to its standard, the entry says so — the silences are part of the record of an industry whose product is discretion.

The McKay lead. Michael directed this guide to include "McKay, created in Los Angeles" — a port-security company of that name founded in Los Angeles. The research is reported in full in the Method section below. Its conclusion, stated here so no reader misses it: no port-security company named McKay, founded in Los Angeles or elsewhere, could be verified from trade, company or registry sources, and the lead is therefore carried as UNVERIFIED — not written up as an entry, and not quietly dropped either. The documented maritime McKay/Mackay names are three, and none fits: Mackay Communications (marine electronics and satellite services, headquartered in Raleigh, North Carolina, with a Los Angeles service office), McKay International Engineers (container-crane engineers of Oakland, merged into Liftech Consultants in 2022), and ISS–McKay (a New Zealand port agency, now wholly Inchcape's). A genuine Los Angeles port-security firm with a near name — McRoberts Maritime Security of San Pedro, in the Port of Los Angeles complex — is included on its own merits, and it is expressly NOT asserted to be the firm Michael meant.

METHOD, GAPS AND EXCLUSIONS

THE McKAY LEAD — FULL REPORT. Searches run October 2026 across web and trade sources for: "McKay" + port security / maritime security / Port of Los Angeles / San Pedro / California security company. Findings: (1) Mackay Communications, Inc. (mackaycomm.com) — marine electronics, navigation and satellite-communications sales and service; founded lineage in marine radio; HQ Raleigh, NC; its published network includes a Los Angeles office (San Pedro area, +1 310 519 7539, la@mackaymarine.com). It is a service company for shipboard electronics — not a security firm, and not Los Angeles-founded. (2) McKay International Engineers — structural/mechanical engineers for container cranes and terminals, Oakland, California; merged into Liftech Consultants Inc. in 2022 after 52 years of joint work. Engineering, not security. (3) ISS-McKay Limited — a New Zealand port agency (Inchcape Shipping Services joint venture, bought out fully in November 2023). Agency work, not security, and not American. (4) No California security-company registration, trade-press item, or company site for a "McKay" port-security firm was found. CONCLUSION: the identification is UNVERIFIED. The most plausible near-referent in the actual Port of Los Angeles is McRoberts Maritime Security (411 N Harbor Blvd, San Pedro; mcroberts1876.com), a genuine harbour security firm — but equating "McKay" with "McRoberts" would be a guess, and this guide does not guess. If Michael can supply a further detail (a founder's name, a decade, a terminal), the entry can be researched again and added with evidence.

Roster scope: the specialists section favours firms whose port, terminal or vessel-security work is documented; the operators' section documents the in-house model that actually secures most large terminals; the screening section covers the three technology majors whose systems dominate container inspection. Regional guarding contractors below this scale (the hundreds of local firms like the San Pedro example) are represented by type, not enumerated — a full census is not honestly possible.
