Does every automotive supplier need TISAX?▼
No. TISAX is required when a customer, typically a European OEM or a tier one working with one, asks for a specific assessment level. Many suppliers to U.S. OEMs instead get information security questionnaires or audits built on similar controls. Check your customer contracts and supplier portals for the actual requirement. If TISAX is required, an accredited audit provider performs the assessment and the result is shared through the ENX portal. We help you get the IT controls, policies and evidence ready so the assessment finds a working program rather than a pile of new documents.
Can you support our EDI if a third party handles the mapping?▼
Yes. Many suppliers outsource maps and trading partner setup to an EDI provider or VAN while keeping a translator or integration server in-house. We handle the infrastructure: the server or cloud connection, AS2 certificates, firewall rules, monitoring for failed transmissions, and backups of configurations. When a map breaks or a customer changes a spec, we coordinate with your EDI provider so production control isn't stuck in the middle. The goal is that nobody discovers a missed 862 when the customer calls asking where the parts are.
Will segmenting the plant network disrupt production?▼
Done carelessly it could, which is why we plan it with your controls engineers and maintenance team. We start by observing what traffic the cells, MES and ERP actually exchange, then build firewall rules that allow it before enforcing anything. Changes happen during planned downtime or changeovers, one area at a time, with a rollback plan. We don't change PLC programs, robot configurations or vision systems; if a device needs a new IP address or setting, your controls team or the machine builder makes that change while we handle the network side.
What do OEMs ask suppliers about cybersecurity?▼
Common questions cover MFA on email and remote access, endpoint protection, backup and recovery testing, how CAD and customer data are shared, incident response plans, who has administrator rights and how vendors connect to plant equipment. Some customers also ask about how you assess your own sub-tier suppliers. The answers need to be accurate, because a wrong one can surface later in an audit or after an incident. We help you answer honestly, and where the true answer is no, we plan the work to change it and document the timeline.
How should we share CAD files and PPAP documents with customers?▼
Through controlled channels, not personal email or random file-sharing links. Many OEMs provide supplier portals or required exchange tools, and those should be the default for their data. For sub-tier suppliers and internal teams, we set up managed sharing in Microsoft 365 or a similar platform, with expiring links, access limited to named people and logging of downloads. That keeps customer design data where your NDAs say it should be, and it gives you a record if a customer ever asks who received a particular drawing.
Do you only work with plants near your offices?▼
No. Most monitoring, help desk and engineering work is done remotely by U.S.-based engineers, which suits suppliers with plants in several states. For physical work such as installing firewalls, recabling a cell or swapping a failed switch, we handle it ourselves near our offices or direct a vetted local technician while our engineer stays on the call. That lets us support automotive suppliers in any state without making every fix wait for travel.
