These are the three cornerstones of S.T

There’s only one way to stop information being spread, and that’s by taking effective action to prevent it from happening.

For us, the confidentiality agreement is an essential link in the chain of trust that we build together from the outset, covering everything from routine document management to the organisation of entire buildings with controlled access.

NDA, three letters giving you total assurance.

Although we're at home in the automotive industry, we also deliver value in other areas.

We work across multiple industries, in Italy and around the world.

There’s always a before and an after.

It was in 2007 when Tommaso Scala turned the key that fired up S.T.

Now, fourteen years on, a well-structured, experienced organisation has taken the place of that original project.

S.T. initially dealt with failure analysis and technical approval of designs. This was followed by quality control methods and analysis of components and entire mechanical systems.

Our constantly growing workforce, in terms of staff numbers and expertise, is the best touchstone for your projects. Along with an infinite list of activities that will change how you view your systems.
