A co-packer is a data-segregation problem wearing a hard hat: dozens of competing brands' formulas, specs and forecasts under one roof, one plant that makes them all, and a portal or EDI link to every client. CyberFortify runs manual API, web, cloud, network and OT/ICS penetration tests here, aimed at whether one client - or one employee - can reach another client's recipes. Aligned to trade-secret protection, SOC 2, NIST 800-82, IEC 62443 and the CIS Controls. Delivered remotely from our Gulf base on a daily overlap window, with on-site OT work where it counts. Fixed price, audit-ready reporting, free retest.
// 01 Why Chino businesses need penetration testing
Chino sits in a stretch of the western Inland Empire that spent a century as an agricultural preserve and is now dense with processing plants and distribution. A large share of that base is contract work: co-packers and contract manufacturers that do not own the brands they produce. They fill, blend, bake, bottle and package on behalf of others, which means their competitive value is the confidence a brand has that its recipe is safe in your building.
That inverts the usual threat model. The crown jewels here are not your own IP - they are dozens of other companies' trade secrets, held side by side, often for brands that compete on the same shelf. One ERP schedules both their runs and one file store holds both their specs. The failure mode that ends a co-packer is not downtime; it is one client's formula reaching another client, an employee, or the open market because an access control was trusted when it should have been enforced.
Scanning cannot find that class of flaw. A scanner flags an unpatched service; it cannot tell you that a portal account scoped to one brand can list another brand's specification documents, or that a plant-floor account inherits read access to the whole recipe library. Those are authorisation and segregation decisions, and confirming them takes a tester who will actually try to cross the wall between two clients and prove whether it holds.
// 02 Compliance and regulatory drivers in Chino
There is no single statute that says "pentest your co-packing plant." The drivers are contractual, defensive and legal - the audits your clients run on you, the report they ask you to hold, and the standard of care that keeps a trade secret protectable. These are the requirements we most often map evidence against.
Trade-secret protection
A formula stays a legally protected trade secret only while you take reasonable measures to guard it. Independent testing of the controls around each client's recipe is direct evidence of that reasonable care.
SOC 2 & client security audits
Brands run security and quality audits before they trust a co-packer with a formula, and SOC 2 is the report they most often ask you to produce. Both rest on independent testing of your segregation and access controls.
NIST 800-82 & IEC 62443
The plant floor - PLCs, HMIs, historians, MES and the recipe-download path - is measured against NIST SP 800-82 and IEC 62443. We test the segmentation between corporate IT and the line against both.
NIST CSF & CIS Controls
Most co-manufacturers anchor the wider security programme to NIST CSF and the CIS Controls. Penetration testing evidences the Identify, Protect and Detect functions and the controls behind them.
CCPA / CPRA
Employee, buyer and customer records fall under California's consumer-privacy regime, which adds rights and risk-assessment duties. Our privacy-regulation guidance sets out how it compares.
FSMA - alongside, not the driver
Food-safety rules such as FSMA govern the product, not the network, and are covered thoroughly by our produce and dairy pages. Here they sit beside the security case rather than defining it.
// 03 Penetration testing services for Chino
Chino engagements weight authorisation and segmentation over the perimeter, because the risk lives in the walls between clients and between IT and the plant. Client-portal and API testing lead; ERP and file-share authorisation follow; OT and network testing prove the recipe path from office to line.
API pen testing
Client portals and EDI - broken object-level authorisation, tenant isolation and token scope, so one client's session cannot reach another's recipes or specifications.
Web application pen testing
The client portal, quality and specification systems and internal ERP front ends, tested against the OWASP Top 10 and cross-client access and business-logic abuse.
OT / ICS pen testing
Processing-plant PLCs, HMIs, historians and MES, plus the IT-to-OT segmentation and recipe-download path, tested carefully to NIST 800-82 and IEC 62443.
Cloud pen testing
Identity, tenant isolation, storage exposure and service-account scope across the cloud ERP, file stores and portals holding many clients' data.
Network pen testing
External, internal and Active Directory testing, with segmentation checks between corporate, plant and storage networks and shared recipe repositories.
Red teaming
Goal-based simulation of an insider or intruder exfiltrating a specific client's formulation, testing whether the theft is detected before the data leaves.
// 04 How we deliver to Chino
We will not pretend otherwise: CyberFortify is a Gulf-based firm on UTC+3, and Chino sits ten to eleven hours behind us. We have no California office and no local staff. What we have is a working pattern built around that gap - our late afternoon and evening is your morning, held open daily for stand-ups, live triage and read-outs. Testing continues while Chino is offline, so confirmed findings are waiting when the shift starts.
What runs remotely
Client-portal, API, web, cloud and external testing, plus the multi-client segregation and ERP authorisation work that sits at the centre of a co-packer engagement. Findings land in a shared channel as confirmed, and critical cross-client exposure is escalated immediately.
What we do on-site
Processing-plant OT, internal network, wireless and segmentation testing where a tester genuinely needs to be on the wire beside the line. We travel when it adds value and say so when it does not.
Every engagement opens with a free 30-minute scoping call and a fixed-price quote within the hour. For live plants we agree test windows around production runs and set stop conditions for anything touching the floor, and a free retest proves the fixes.
// 05 Industries we secure in Chino
Chino's risk profile is shaped by contract manufacturing, food and beverage processing and a heavy distribution base built on the old agricultural preserve.
// 06 Our methodology
Chino engagements follow the same audit-defensible process we run everywhere, tuned to the segregation problem at the centre of this market. Testing is grounded in the PTES and NIST SP 800-115, with exploitation mapped to MITRE ATT&CK tactics, application work driven by OWASP including the API Security Top 10, and OT work to NIST 800-82 and IEC 62443. As a CREST Accreditation Pathway firm we lead with manual testing - automation supports the tester, never replaces one.
Scoping & rules of engagement
Targets, portal and EDI surfaces, client-tenant boundaries, plant stop conditions, test accounts and escalation paths agreed in writing first.
Fixed quote in 1hReconnaissance & threat modelling
Attack surface mapped around segregation - which account, portal or line can reach which client's formulas, specs and forecasts, and where the walls are meant to be.
ATT&CK alignedManual exploitation
Weaknesses are exploited and chained under controlled conditions, with cross-client access proven using seeded records for mock clients - never a real client's formulation.
Controlled exploitReporting & free retest
Executive summary, CVSS-scored detail and mapping to SOC 2, NIST 800-82, IEC 62443, NIST CSF or the CIS Controls - plus a free retest once fixes ship.
Audit-ready// 07 Why CyberFortify for Chino
A scan-and-report vendor
Automated output rebadged as a penetration test, blind to authorisation logic, unable to reason about whether one client's account can reach another client's recipe or whether the plant floor is walled off from the office.
CyberFortify
A Gulf-based, CREST-pathway team candid about the time difference and structured around it. Manual exploitation aimed at the segregation seam between clients and between IT and OT, findings mapped to your clients' audit frameworks, fixed pricing and a free retest.
Chino engagements most often pair an API and client-portal assessment with a cloud penetration test, since a co-packer's multi-client risk splits between the authorisation logic in front of the data and the tenant isolation underneath it. Where a specific formulation is the target, we add red teaming to test whether exfiltration would be detected. This work extends to fellow food-manufacturing centres such as Modesto and neighbouring Inland Empire industry in Ontario and Corona.
// 08 Frequently asked questions
As a co-packer, can you prove one client cannot reach another client's recipes and specs?
That is the test co-manufacturers ask us for most. We treat multi-client segregation as the primary objective: whether a login, API token or portal session scoped to one brand can read, list or enumerate another brand's formulas, specifications, artwork or forecasts. We check object-level authorisation in the client portal and the product-lifecycle or ERP layer, whether identifiers can be substituted to cross a tenant boundary, and whether shared file stores and reporting exports honour the same walls. We prove it with seeded records for two mock clients, never with a real client's trade secrets.
How do you test the plant floor without stopping a production line?
Processing OT gets a deliberately careful approach. We start with passive review and architecture analysis of the segmentation between corporate IT and the plant - PLCs, HMIs, historians, MES and the recipe-download path to the line - aligned with NIST 800-82 and IEC 62443. Active testing of production controllers happens only in an agreed window, against non-production or mirrored assets where one exists, with clear stop conditions. The goal is to show whether an attacker who lands in the office network can reach or alter a recipe on the line, not to risk an unplanned stoppage.
Which standards and obligations drive penetration testing for a Chino contract manufacturer?
There is no single food-processing pentest law, so the drivers are contractual and defensive. Client security and quality audits increasingly require independent testing before they trust you with a formula, and SOC 2 is the report brands ask co-packers to produce. Trade-secret protection is the business framing: a secret keeps its legal protection only while you take reasonable measures to guard it, and testing evidences those measures. Processing OT is measured against NIST 800-82 and IEC 62443, the wider programme against NIST CSF and the CIS Controls, and employee and customer data against CCPA/CPRA. Food-safety rules such as FSMA sit alongside but are not the security driver here.
With your team in the Gulf, how does the time gap work for a Chino engagement?
We will be straight about it: CyberFortify is a Gulf-based firm on UTC+3, ten to eleven hours ahead of Chino, with no California office or local staff. We hold a deliberate daily overlap window - our late afternoon and evening is your morning - for stand-ups, live triage and read-outs with your plant IT and quality teams. Testing runs on while your site is offline, so confirmed findings are usually waiting when the shift starts.
How fast can we get a quote for a Chino engagement?
Book a free 30-minute scoping call and we return a fixed-price quote, usually within the hour and always within one business day. The report is written to hand straight to a client auditor or your SOC 2 assessor, and a remediation retest is included once your fixes ship.
