The service targets critical infrastructure operators, private businesses, public institutions, and financial services.

VenSearch Intelligence
Ideal Customer
- Kumo is squarely focused on operators of UK Critical National Infrastructure, particularly those managing distributed physical assets such as power stations, pumping stations, and similar utilities.
- The service is architected for organisations that need to secure IoT devices and remote assets at multiple geographically dispersed locations under centralised monitoring.
Key Differentiators
- Kumo's core differentiator is its approach of complete network segregation: rather than using VPNs (which assume all devices are trustworthy), Kumo deploys physical security devices at each asset location configured to communicate only with Tivarri's UK data centres, ignoring all other traffic.
- This eliminates lateral movement risk between compromised IoT assets.
Industries Served
- Kumo's primary focus is on UK Critical National Infrastructure (CNI), with a specific emphasis on electricity generation — the company's own website states it is 'a leading provider to UK power stations.' The broader Tivarri parent organisation also serves regulated financial services firms including hedge funds, asset managers, and wealth managers, as well as charities.
- The engineering team's background includes designing networks for high street banks, power stations, and Police systems.
