You can show the scale and impact without naming the client or disclosing confidential figures. Protecting confidential information is more important than making the bullet overly specific.

Recruiters need enough context to understand the difficulty, ownership, and result of the work. They do not need the client's identity. You can often use industry, geography, approximate scale, ranges, or percentage improvements instead.

Instead of naming the company, you might write, 'Led pricing analysis for a North American industrial client, identifying opportunities worth approximately $10M annually.' Use only figures you are permitted to disclose.

Rewrite the bullet around your action and business impact, then remove anything that could identify the client or reveal protected information. When in doubt, use a broader description rather than stretching confidentiality rules. If useful, this guide on consulting resume gives more detail.

I've always anonymized client names and kept the impact numbers broad enough to be safe.

industry + size + result usually gives enough context.
