Why Critical Asset

Aerial inspection and threat intelligence. In one day.

We pair aerial inspection with threat intelligence in a single engagement — an unusual combination in the UK drone market. You get back a broker-ready report: every finding dual-graded, an operator-owned control-review pathway across three horizons, and a one-page summary your broker can hand to the underwriter before renewal.

The operational detail — what happens on the day, every deliverable, how findings are graded, pricing tiers — lives on the Assessment page.

Our flagship service

The Site Security Vulnerability Assessment.

One engagement combining two disciplines. The site's public attack surface and its physical findings, documented in a format built for broker and underwriter review before renewal.

Who it’s for

Three buyer profiles.

Solar & renewable energy sites
Cable theft, copper theft, arson and insurer-driven loss prevention. Unit economics often favour prevention: £3,950 against £50k–£500k+ loss events.
Large estates & rural commercial sites
Remote locations, insurance-aware asset managers, and the perimeter, access-control and CCTV blind spots that come with scale.
Broker & underwriter-led briefs
Pre-renewal evidence, underwriter-facing risk context, post-incident documentation. Report format built from the outset for underwriter handover.

How we work

Grown-up operations, not hobbyist kit.

REGULATORY

CAA-authorised, insured, ICO-registered

UK CAA operational authorisation, £10m public liability, ICO data controller registration. Every flight planned against airspace, NOTAMs and landowner permissions.

EVIDENCE

Findings are dual-graded

Every finding carries a banded risk priority (severity × likelihood as a banded judgement) and an evidence confidence grade (Admiralty A–F / 1–6). Your broker and underwriter can see the strength of the source, not just the headline.

SCOPE DISCIPLINE

Passive reconnaissance only

We map the attack surface the way an outsider sees it. No intrusive testing, no attempted authentication, and no surprises for your IT team or your insurer.
