We present results from two distinct searches for Vector-Like Leptons (VLLs) conducted by
the CMS experiment using data collected during LHC Run 2. The first analysis uses a model-
independent approach probing multilepton final states, while the second one focuses on hadronic
final states with multiple tau leptons, leveraging model-dependent techniques. Both searches target
SU(2) doublet VLL scenarios with couplings to third-generation Standard Model (SM) leptons
while the multilepton analysis also targets singlet VLL scenarios. The first analysis yields results
that exclude VLL masses up to 1040 GeV in the doublet scenario and between 125-170 GeV in
the singlet scenario. In the second analysis, the maximum likelihood fit prefers the presence of
signal at the level of 2.8 standard deviations, for a representative VLL mass point of 600 GeV.
Finally, projections for the High-Luminosity LHC (HL-LHC) suggest sensitivity improvements,
extending the excluded mass range further into the multi-TeV region.
