About Us

The Interassekuranz Sitt & Overlack GmbH is an insurance broker who is truly independent from insurers and banks, and is associated with the Ecclesia Group. Unlike conventional intermediaries or agencies acting as an "extended arm" of insurers, we are advisers and you can expect us to exclusively pursue the interests of our clients when dealing with insurance companies.

Identifying our clients risks is our job. We then map, assess and quantify the threats that those risks pose to our clients and develop bespoke insurance solutions individually designed to meet our clients' requirements. We cooperate with all renowned insurance companies.

Above and beyond this, our employees are the point of contact in the event of loss. Not only the arrangement of individually designed insurance concepts but also the entire claims settlement process is handled in our competent teams.

With about 90 employees we have achieved a strong and distinctive position in the market, and are in good shape to deal with future challenges.

More than 1,000 clients from almost all industries and sectors reflect our wide range of competences.

Merits of our services:

  • Individuality: we design client-specific insurance solutions.
  • Risk assessment: in close teamwork with our clients we analyse and assess their individual corporate risk situation.
  • Independence: we exclusively pursue the interests of our clients.
  • Personal support: we care for the continuous contact to our customers.
  • Loss prevention: Our proven consulting philosphy is "preventing is better than insuring".


Our client advisors are looking forward to meet you personally.
