The Cyber Exposure Score is a published 0–100 formula built only from publicly observable signals. How this is calculated.
This domain scores better than 88% of the 404 Manufacturing organisations we track (cohort median 78). The sample is seeded from public incident data, not a random cross-section of the sector.

This domain is named on the public leak site of a ransomware group. A leak-site post is a claim published by the group — not a verified fact, and not a statement by this organization. Groups list victims who did not pay, overstate what they hold, and occasionally name the wrong company. What is certain is that the listing itself is public.
| Group | Listed | Sector |

Leak-site postings are collected here from 2026-07-30 onwards; an earlier listing would not appear above.

Lookalike domains (2 registered of 150 checked)
Registered permutations of this domain. Existence is a fact, not an accusation — ownership and intent are not assessed. Those able to receive mail are the ones usable for invoice fraud and phishing. The Risk score (0–100) is a published formula weighing mail capability, registration age, spelling, what the homepage shows and phishing-feed hits, reduced when a name looks brand-owned (same registrar/nameservers, a redirect to this domain) or merely parked. How this is calculated.

criticalTreat data published on a leak site as disclosed
This domain is named on thegentlemen's public leak site on 2026-10-09. A leak-site post is a claim published by the group, not a verified fact — but the post itself is public, and if it is accurate the data is already out. Confirm the claim, then work from the assumption of disclosure: rotate every credential that touched the affected systems, invalidate active sessions, and check your notification duties under GDPR Art. 33/34.
