Consultants: turn a client deliverable into a shareable sample

Jane Example just finished a rebrand for a client. She wants to show the deliverable on her website, but the contract calls the project confidential. ONYRI Sanitize can mask the client's name and numbers in minutes. That turns the deliverable into a sample, once the contract lets you show anything at all.

This guide is for consultants, agencies and freelancers who want to reuse real work as a sample. We make ONYRI Sanitize, so read this with that in mind. Legal points below are attributed and dated September 2026. This is not legal advice.

Why check the contract or NDA before you share anything?

Most consulting and agency contracts include a confidentiality clause. Under EU law, a trade secret must pass a three-part test. The information must be secret, have commercial value because of that secrecy, and be protected by reasonable steps from its owner. That test comes from Article 2 of Directive (EU) 2016/943. A client deliverable often meets all three, whether or not the contract uses the word secret.

• Does the clause allow an anonymized case study, or does it ban sharing outright.
• Does it require the client's written consent for any external use, redacted or not.
• Is there a time limit on confidentiality, or does it run forever.
• Are you required to return or delete the client's files once the project ends.

How do you hide the client's name, brand and project code?

ONYRI Sanitize detects a company name only with a legal form attached (SAS, SARL, Ltd, Inc.…); it still has no detector for project codes, too many to list in every industry. You add missing names or codes yourself. Under Also mask, type the client's name, its brand names, and the project's internal code name. Every occurrence in the document gets masked, on every page.

• Add the client's legal name and any short form your team uses internally.
• Add product or campaign names that are specific to this client.
• For a repeat client, create a custom rule instead of Also mask. Rules save to your profile and cover every new file.
• Check footers and email signatures. They often name the client even when the body text does not.

Black marker or Token mode for a portfolio sample?

Black marker draws an opaque, irreversible bar over each value, in every plan. Token mode, on Pro, replaces each value with a steady label instead. An amount reads as [AMT1]. A name you added under Also mask reads as [+1], the same mark every time it appears. A sample built to show your reasoning often works better in Token mode. A sample built only to prove you delivered something real works fine in Black marker.

What will ONYRI Sanitize not catch for you?

Detectors read text. They do not read images. A logo, a signature, a photo of a person, or a chart with the client's name built into its labels stays exactly as it is. So does a company name that only appears as a picture, not as text.

• Crop or blur a logo in an image editor before you import the file.
• Rebuild a chart with placeholder labels if the original names the client inside the image itself.
• Look for a screenshot inside the document. It is a picture, so nothing on it gets masked.
• Read every page at normal size before you download. A small logo is easy to scroll past.

What is left to check before you send the file?

The export keeps your original file name and adds anonymized at the end. If the file name itself names the client or the project, rename it by hand before you send it. The export also drops the original file's comments and document properties, such as its author or title. It keeps none of the file's text as selectable text: it is a flattened image.

On pricing: Black marker, the base detectors and 3 custom rules are on the Free plan already, enough for an occasional sample. Token mode and unlimited custom rules sit on Pro, at €9.90 a month or €99 a year. A one-time 7-day pass (€5.90) gives you all of Pro for a week.
