Assets and suggestions overlap checks

The biggest functional improvement this week is that assets and suggestions are cross-checked from now on. If a new asset is added, manually or through discovery, any suggestions about that same assets are automatically removed. The same goes for new suggestions. They are dropped if the suggested asset already exists.

If feels a bit odd that this is only added now and not much earlier. Thing is, it was not a problem in the past. Some accounts have gotten so big with so many related assets on the attack surface that now it had become a problem.

Again, this week's update had more improvements in software detection, and new scanner nodes were added. With the addition of nodes in Brazil, Italy and Sweden the total number of locations we scan from is now 14.
