Greig Tonks knocked over a late penalty to give Edinburgh a hard-earned victory over Treviso in Italy.
First-half tries from Phil Burleigh, Damien Hoyland and Sam Beard gave the visitors a great platform.
But Andrea Pratichetti and Duncan Naude touched down either side of half-time and Jayden Hayward kicked his fourth successful penalty to level the game.
Tonks then took his points tally to 12 with a penalty on 72 minutes to make it two wins from two in the Pro12.
Following on from last weekend's 16-9 win against Leinster, Burleigh opened the scoring after just four minutes, while winger Hoyland made it three tries in two games as he sprinted clear.
Beard provided the pass for Hoyland and then dived in at the corner seven minutes before half time.
But a good spell of home pressure saw Pratichetti touch down against the post protector and Edinburgh's lead was cut to eight points at the interval.
Edinburgh then had Neil Cochrane sin-binned for repeated infringements and Naude forced his way over the line to cut the deficit further, although Hayward failed to land the extras this time.
But the New Zealander would later level the game at 24-24 before Tonks delivered the winning kick.
Edinburgh needed to withstand a further barrage, with Treviso knocking on just short of the line before Alan Solomons' side could boot the ball clear.
