Counterfeiting is a global problem

Product piracy and manipulation affect entire industries — from patient safety to tax revenue and brand value. In 2021, counterfeit and pirated goods accounted for around USD 467 billion in global trade, up to 4.7 % of EU imports. A covert marker adds a layer of security that is invisible in daily use, yet unambiguous when you check for it.

  • Pharmaceuticals — patient safety and supply-chain integrity.
  • Electronics and spare parts — genuine vs. counterfeit components.
  • Currency, tax labels and official documents.
  • Cosmetics and consumer goods — brand protection.

Tailored to your requirements

Every product is different, so every solution is. We scale from a simple, high-volume marker for mass-market goods to a sophisticated, hard-to-copy protection with a demanding read-out for premium applications. You choose the level of security you need — and build only the level of protection your case needs.

We don't publish how the protection works — that's the point. The exact marker and read-out are defined with you, for your product, and stay between us.

Tell us what you need to protect.

Send us the product, the material it is made of and how you want to verify it — we'll propose a suitable marker, the right read-out and prepare a sample.

What isishield solves

Three jobs, one tailored material solution — from the point of check to the recycling stream.

Authenticate

A clear genuine / not-genuine decision at the point of check — brand protection and imitation prevention.

Trace

Follow goods along the supply chain and detect diversion.

Sort & identify

Mark plastics and materials so they can be identified and sorted — supporting identification and recycling workflows.

One solution provider, the right network

One solution provider — we make the German-engineered marker and bring in the right read-out and integration expertise, so you don’t have to align several vendors yourself.

Marker material — made in Germany

Our core competence: the luminescent marker itself, engineered and produced in Germany.

Read-out & detection

The matching verification technology, specified and provided through our partner network.

Integration into any medium

Our markers can be worked into almost any medium — plastics, fibres, inks, coatings or the component itself.

From inquiry to sample

A short, guided path — no off-the-shelf security, just the solution your case needs.
