Business insurance for low-touch SaaS (UK)

Hey guys. We've just incorporated our low-touch SaaS product in the UK (private limited) and I'm wondering if anyone has recommendations for what to do with regards to buying business insurance?

I've had a limited company in the UK before. It was a consultancy firm, and we had a comprehensive offering from Hiscox:

• Employers' liability
• Cyber and data
• Professional indemnity
• Public and products liability

Would this be sufficient for a SaaS business, or is something missing? Is it too much? :)

I'm kind of surprised there isn't a niche insurance product out there for the SaaS industry...
