It appears to be 4 letters, possibly 3 or 4 capital letters.
BTW anons… seem like Xkeyscore may have been the system the contractors had access to get at the illegal FISA 702 queries.
Xkeyscore seems to fit in the blacked out application name? Anyone?
4 of the 5 companies below can fit into a redacted FISA-search company. One of those 4 likely held the contractors doing FISA abuses for FBI/NSD. My guess.

For the first time since spy agencies began outsourcing their core analytic and operational work in the late 1990s, the bulk of the contracted work goes to a handful of companies: Leidos, Booz Allen Hamilton, CSRA, SAIC, and CACI International.
Every line of the Judaic star is the square root of 2 in the cross section of a cube with value 1.
The angle on a mason's apron is something totally different.
Once again for the slow kids: The FBI/NSD had a company with "contractors" (4 people) with access to a tool with full FISA search information against minimalization guidelines.
The contracting agency as well as the names of the 4 individuals are redacted from all public documents. One company, 4 people.
CSRA (now rolled into General Dynamics) is my first guess who the contracting company is, although there are several 4 letter companies who could have had the access.
