Wirewalker

Wirewalker is a Tier III upgrade in the Codestrider column of the Gauntlet upgrade tree from the Season of the Splicer. It costs 500 Decrypted Data. When players activate its benefit at certain obstacles in Expunge missions, it reveals shortcuts or removes the obstacle.

This information comes from 2021 reporting on Season of the Splicer, so later patches may have changed the upgrade.
