Ask HN: Who is underwriting your technology company's insurance?

When it comes to insuring your small to medium sized technology business, who did you purchase your insurance from and why? Which companies understand the needs of tech businesses? Which companies offer the best data breach policies? Were you able to get general liability and data coverage through the same underwriter? Did you purchase direct or through a local agent? Also, after having purchased (and possibly having made a claim on your policy), what advice would you offer for terms and additional coverage?
