Abstract: We report here on the recent results of a monitoring campaign we have been carrying out with Swift/XRT on a sample of four Supergiant Fast X-ray Transients. The main goal of this large programme (with a net Swift/XRT exposure of 540 ks, updated to 2009, August, 31) is to address several main open issues related to this new class of High Mass X-ray Binaries hosting OB supergiant stars as companions. Here we summarize the most important results obtained between October 2007 and August 2009.<br />Published on the Proceedings of the conference X-Ray Astronomy 2009, Present Status, multiwavelenght approach and future perspectives, September 7 - 11, 2009, Bologna, Italy. Revised version according to the referee's report
