Finding any would be a first step.

Be careful what you ask for. Revealing your existence to alien species could be one of the dumbest mistakes you could make in the universe. Especially when our technology is not even capable of interstellar travel. Thus any species that comes to visit us will be more technologically advanced. If they are more advanced it likely won't be by 10 or 100 years, but possibly one million years or more. We would be sitting ducks. There are many ways this could go badly: - They could be so advanced as to consider us a useless nuisance. They could treat us the way we treat ants. - They could be inherently nice and rational (by our standards) but correctly see us as a threat to them as our technology advances in the future. Our tribal tendencies (culminating in war) are on display constantly. At best they would just keep their distance. At worst they might wipe us out for their own self preservation. - Even a benevolent species could be disastrous for us if they transferred technology before we were ready for it.

  Assuming travelling faster than light remains impossible. Theres the advantage that there are significantly less stars in the range of 0 to 100 lightyears than there are stars between 100 and 200 lightyears away. This means even if theres an alien civilisation, All the advanced ones must be far away and therefore our technosignature will never be exposed for XXXX years. Our biggest signature/threat is that alien civilisations are receiving signals from our planet as it was thousands or millions of years ago and have send out a capable ship. But we still have the advantage of time. even travelling at near light speed, we might notice their technological attainment far before their ship can arrive. And thanks to einstein, the time dilation they experience at light speed means they dont have time to develop further during their travel. so an alien ship arriving is not game over as we have the space-time advantage. Therefore, military forces a few hundred years from now could be interested in defensive technosignature detection.
