The bench 6 judges, built for this category
The IT Lead v1.0
Head of a three-person IT team at a 140-person mechanical engineering firm with two plants and a sales office in Vienna. The VPN still runs on the firewall, and every update of it is a weekend. Wants a client that installs through Intune and connects on its own, sign-in with Microsoft Entra so a leaver loses access the same day, the ERP and the file server reachable without opening the whole network, a fixed IP for the supplier portal, and a price per user that survives the next budget round.
The DevOps Engineer v1.0
Platform engineer at a sixty-person software company with servers at Hetzner, a Kubernetes cluster on AWS and a bastion host everyone shares a key for. Wants a mesh that reaches every server and cluster without inbound ports, access policies kept in Git and applied with Terraform, SSH access tied to the identity provider, connectors that run as containers, and a published architecture that says what the vendor's relays can see.
The MSP Technician v1.0
Senior technician at an IT service provider in Hamburg that looks after thirty clients, from tax advisers to a dental chain. Each client has its own remote access, set up by whoever was on site that year. Wants one console with a tenant per client, gateways and users added in minutes, access logs a client can be shown after an incident, billing per tenant, and prices per user that can be quoted without calling the vendor first.
The Operations Manager v1.0
Runs operations at a fifty-person consultancy where a third of the work is done by freelancers on their own laptops and the rest of the team travels to client sites. Has no IT department, only an external provider billed by the hour. Wants each freelancer to reach one project system and nothing else, access that ends with the contract, a setup a non-specialist can follow, and no call to the helpdesk from a hotel lobby.
The Information Security Officer v1.0
Information security officer at a regional energy supplier that falls under NIS2 and was asked by its auditor who could reach the control systems last year. Wants access granted per resource, not per network, device checks before a connection, every access and admin change in a log that reaches the SIEM, an independent audit of the product, and the identities and logs kept in Europe by a vendor whose subprocessors are listed.
The Skeptic v1.0
Has seen "zero trust" on a VPN that still drops every user into the whole office network, "no logs" from a vendor that keeps every connection for a year, and a remote access tool that locked out the whole company when its own control plane went down. Asks who can see the traffic and the metadata, what keeps working when the vendor is offline, whether the audit was published or only announced — and whether the network could be moved to a self-hosted server.
