Well first, yes, shields and stuff.
But second, borg cubes are horrible shapes for defence. They are hard to destroy because of redundancy and size. Their important systems are spread out over the whole giant ass ship and are numerous. But a cube is easy to hit and eats everything you throw at it. DS9 has some redundancy as well (afaik, the six pylons are almost identical) and a far smaller area to hit.
BSG’s got a similar approach, trying to present the most compact profile while having a relatively large inside room, but combines that with a sloped surface that virtually thickens the hull against most angles of attack.
