Abstract We present a non-supersymmetric deformation of probe branes describing conformal defects of codimension two in AdS/CFT. The worldvolume of the probe branes is deformed from AdS p × S 1 embedded in an AdS p +2 × ℳ D − p − 2 background to an embedding of Janus form, which uses an AdS p− 1 slicing of AdS p and in which the brane bends along the slicing coordinate. In field theory terms this realizes conformal interfaces on codimension- two defects. We discuss these “Janus on the brane” solutions for AdS 3 × S 1 D3-branes in the AdS 5 × S 5 solution of Type IIB, realizing interfaces on surface defects in $$ \mathcal{N} $$ N = 4 SYM, and show that similar solutions exist for probe branes in AdS p +2 × S 9 −p vacua of M-theory and in the AdS 6 × S 4 solution of massive Type IIA.
