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 27% of the 447 Manufacturing organisations we track (cohort median 78). The sample is seeded from public incident data, not a random cross-section of the sector.

Posture summary

Software versions inside a published affected range (3, 3 known-exploited)

The public response carried a version for these products, and NVD publishes an affected range that contains it. This is not proof the software is unpatched — a distribution backport keeps the original version string while carrying the fix, so a fully patched build can appear here. Both halves of the comparison are public and checkable.

1 further match(es), with the affected range published for each, are part of the complete audit.

Ransomware leak-site listings (1)

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.

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

Public attack surface (1 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 (1 registered of 110 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.

Recommendations

• highEnforce DMARC

  No enforcing DMARC policy was observed. Publish a DMARC record and move to p=quarantine then p=reject to reduce spoofing.

• mediumEnable DKIM

  No DKIM record was found on common selectors. Enable DKIM signing.

• mediumEnable DNSSEC

  DNSSEC signing was not detected for this domain.

• criticalConfirm software versions that fall inside a published affected range

  The public response carried a version for 4 detected product(s), and 3 published CVE ranges contain what we read. Apache HTTP Server 1.3.34 falls inside the range published as affected by CVE-2021-40438 (<= 2.4.48). 3 are on CISA's known-exploited list, meaning exploitation has been observed in the wild. This is an observation about a version string, not proof the software is unpatched: a distribution backport keeps the original version while carrying the fix. Check the build you are actually running, and patch or upgrade whatever is genuinely inside the range.

• 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.

• mediumLookalike domains are registered

  1 permutation(s) of this domain are registered. None accept mail today, but that can change without notice.

• mediumUpgrade software past its end of life

  Apache HTTP Server 1.3: the project no longer fixes this release. A Linux distribution may still patch it, so check with whoever maintains the server, then plan the upgrade.

• lowUpdate JavaScript libraries with published issues

  jQuery 1.12.4: these versions have publicly listed issues. Whether they can be used against this site depends on how it calls them; updating is usually the quicker answer.

• lowTurn on the registrar transfer lock

  The registry shows no transfer lock on this domain. Most registrars offer it free, and it stops the name being moved away without an extra step.
