What Are the Key Differences Between Marsh and Travelers Tech E&O Insurance?

Custom Data-Center Programs vs One Insurer's Standard Product

Marsh treats technology E&O as a professional-liability specialty and says off-the-shelf forms were not built for the scale, density and aggregation of modern data centers, so it designs programs combining Tech E&O with property, casualty and other lines, with insurers it does not name. Travelers underwrites technology E&O as one selectable agreement inside CyberRisk Tech, for technology and life-sciences companies from startup to established, bought through an agent or Travelers representative. Choose Marsh if you run a data center or need a program too large for a standard form; choose Travelers if you are a tech or life-sciences company that wants a known insurer's product.

Take E&O Alone or With Cyber at Travelers

Travelers keeps its E&O agreement separate from breach-response, cybercrime and business-loss cover, so you can buy E&O alone or add them; its Cyber Risk Services come with the cyber side. Marsh lists technology among several industries its professional-liability team serves, including banking, insurance, asset management, media and healthcare, and describes no application path for this line.

What Should You Confirm in Marsh and Travelers Tech E&O Insurance Quotes?

  • Ask Travelers which agreements your quote includes, and ask Marsh which insurer it would use. [9] [5]
  • If you run a data center, ask Marsh how E&O fits with your property and casualty. [4]
  • Get E&O limits and retentions from both; neither publishes them. [4] [10]
  • Ask Travelers whether its Cyber Risk Services apply if you buy E&O without cyber. [9]

Marsh brokers Tech E&O and builds custom programs pairing it with property and casualty for data centers, which it says off-the-shelf forms leave exposed; Travelers writes E&O itself as a selectable part of CyberRisk Tech, which technology and life-sciences companies can take with or without cyber through an agent.
