We currently have this same scenario, and are trying to consolidate our databases into 1. I think you are better off with a single database because:
There will be 75% less load jobs to maintain/monitor/setup. If there are any additions/changes, there will be only 1 place to fix it. Any indexes/tuning is in one place. Reports which span companies are easier to setup if you have a single database - there will be 1 fact table where there were 4. Queries will be easier to tune.
As far as security is concerned, you are probably going to use MicroStrategy for that purpose, irrespective of 1 or 4 databases.
