Protecting Trade Secrets: The Reasonable Measures the Law Requires

Every trade-secret case eventually turns on one question: did the owner take reasonable measures to keep the information secret? Both the DTSA and the UTSA make reasonable secrecy efforts a requirement — not a best practice. Fail to protect a trade secret, and courts will find it was never a trade secret at all, no matter how valuable or how clearly it was taken.

What "reasonable measures" looks like

The law does not demand perfection or fortress-level security — it demands reasonableness under the circumstances. Courts look at the totality of a company's efforts. A strong program layers several measures:

• Confidentiality agreements. NDAs with employees, contractors, vendors, and partners are the foundation.
• Access controls. Limit access on a need-to-know basis — passwords, encryption, restricted systems, and physical security for sensitive areas.
• Marking. Label confidential documents and files as such, so there is no ambiguity about what is protected.
• Employee policies and training. Clear confidentiality policies, onboarding that explains obligations, and exit interviews that remind departing employees of their duties.
• Vendor and visitor controls. NDAs and access limits for anyone outside the company who touches sensitive information.

The special case of departing employees

Most misappropriation involves employees who leave for a competitor. Practical safeguards — exit interviews, returning devices and files, reminding the employee of NDA obligations, and monitoring for bulk downloads before departure — both prevent loss and build the evidentiary record you would need in litigation.

Why the program is the protection

With patents and copyrights, protection comes from a government grant. With trade secrets, protection is the secrecy program — it simultaneously keeps the information out of competitors' hands and proves, if you ever have to sue for misappropriation, that the information qualified as a trade secret in the first place. Reasonable measures are not overhead; they are the asset.
