Protecting the IP That Is Your Company: A Zero-Trust Primer
At a hard-tech company your designs, models, and source are the whole business, so the old castle-and-moat network never made sense.
Why the perimeter stopped protecting you
The old model assumed a trusted inside and a hostile outside. Once someone got past the VPN, they could reach the file server, the simulation cluster, and the git remote with nothing else in the way. That works until one stolen laptop, one phished engineer, or one over-permissioned contractor turns into a copy of your entire design history.
Zero trust flips the default. No device, user, or service is trusted because of where it sits on the network. Every request to reach something sensitive is checked on its own: who is asking, from what device, in what state, for what resource.
The three things to verify on every request
Identity first: a strong, phishing-resistant login tied to a real human or a named service account, ideally with hardware keys for anyone touching IP. Device second: is this a managed, patched, encrypted machine, or someone's personal laptop. Resource third: grant access to the specific repo, drive, or dataset needed, not the whole share.
Done well, this is invisible most of the day. The engineer signs in once with a hardware key and gets exactly the projects they work on. The contractor gets one repo for ninety days and then loses it automatically.
A practical sequence that does not stall the work
Start by inventorying where your crown jewels actually live: CAD and EDA files, training data, firmware source, lab notebooks. Put strong identity and device checks in front of those first, then widen out. Trying to boil the ocean on day one is how zero-trust projects die.
Next, move from broad network access to per-application access so reaching a system no longer means reaching everything near it. Layer in least-privilege roles, short-lived access for vendors, and logging you can actually review.
What good looks like in six months
Every person and machine has its own verified identity. Sensitive systems are reachable only by the people who need them, on healthy devices, with access that expires on its own. A lost laptop is an inconvenience, not an incident, because the data was never sitting on it unprotected.
None of this requires a security team of ten. It requires a clear inventory, the right defaults, and someone making the policy real and keeping it current. That is the part we run for you.
