In this talk I will describe the derivation of the factorization theorem for small-x BFKL logarithm resummation up to NLL accuracy presented in 2303.13710 by exploiting Glauber operators in SCET. I will contrast our work with the classic LL resummation by Catani & Hautmann 1994, and highlight how our approach offers new insights and provides a systematic framework for extending resummed calculations for DIS coefficient functions and DGLAP anomalous dimensions to higher orders.
