The firm sells you the firm’s name. The work product is whoever wasn’t booked.
Boutique pentest firms staff engagements off the bench. The senior who closed your last review is on a retainer six clients deep; your 2026 audit lands with the new hire who finished training in March. The methodology, the depth of testing, and the polish of the writeup all swing on whichever consultant happens to be open the week your engagement starts.
A Swarm engagement ships the same shape every time: same specialist roster, same coverage map, same report sections in the same order. You can diff two consecutive quarters as a sanity check.
