How are the top Technology, Data & Privacy firms ranked?
Firms are ordered by the Sartori Firm Index — a 0–100 score built from public signals (scale, geographic and practice reach, live hiring). This page lists firms for whom technology, data & privacy is a leading practice. The Index measures public footprint and momentum, not the quality of any firm's technology, data & privacy work.
What does the depth label mean?
“Major”, “strong” and “present” describe how large a share of the firm's mapped attorneys work in technology, data & privacy, relative to the firm's overall size — a footprint signal, not a quality judgement.
