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 17% of the 247 Healthcare organisations we track (cohort median 79). 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.

Public attack surface (161 hostnames in Certificate Transparency)
Hostnames this organization published in public TLS certificates. Passive OSINT — nothing was scanned.
The hostname inventory — which forgotten hosts exist and where — is part of the complete audit for this domain.
Lookalike domains (3 registered of 95 checked, 1 serving no website)
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.
1 of these were registered in the last 90 days, 1 of them able to receive mail. Recent registration is a risk indicator, not evidence of intent: many lookalikes are defensive registrations, unrelated businesses or parked inventory.

criticalTreat data published on a leak site as disclosed
This domain is named on thegentlemen's public leak site on 2026-10-03. 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.
-
criticalReset credentials seen in infostealer logs
Public infostealer telemetry associates 30 employee credential set(s) with this domain — passwords captured from infected devices, which bypass password policy and often session-hijack past MFA. The most recent dates from 2026-09-13. Most commonly Lumma. Force a reset for the affected services, invalidate active sessions, and check the devices themselves.
-
mediumStrengthen password requirements
90% of the exposed employee passwords analysed rate as weak or very weak. Raise minimum length and screen new passwords against breach lists.
-
criticalNewly registered lookalike domains
1 lookalike domain(s) were registered in the last 90 days, 1 of them able to receive mail: santpau.online (37d). Recent registration is one brand-risk indicator among several — with name similarity, mail capability and live web content — and together they describe what a name is able to do, not who registered it or why: many lookalikes are defensive registrations, unrelated businesses or parked inventory. The registration date is a registry fact; ownership and intent are not assessed. Check these against your own registrations, report any that impersonate you to the registrar, warn finance and staff about payment-change requests, and consider defensive registrations.

highMonitor lookalike domains
2 registered lookalike domain(s) can receive mail, which is what makes them usable for invoice fraud and credential phishing. 1 further lookalike(s) are registered but serve no website yet. Monitor them and consider defensive registrations.

mediumReview the public subdomain footprint
161 hostnames for this domain appear in public Certificate Transparency logs. Retire forgotten hosts — stale subdomains are a common entry point and a takeover risk.
