It sounds like they are reproducing entire articles or at lease publishing large chunks verbatim.
You can decide whether you should shut down the practice, or perhaps demand more attribution (or linkage if it's electronic). Plenty of authors are happy to have others distribute their content if it results in promoting them or their services. Of course, if the company is a competitor or sells competitive products, seeking financial damages (or at least sending a firm cease & desist) may be the better approach.
