How to read this report

Safety Score evaluates observed signals. Evidence Confidence measures how complete, direct, fresh, and consistent those signals are.

No automated scan can guarantee that a website is safe.

Independent evidence brief

What we observed about marklayer.app

Updated Oct 4, 2026

The latest scan examined 10 public pages on marklayer.app. Website descriptions below come from the site itself. Registration, connection and threat findings were checked separately.

Purpose and visible content

On its About page, the site says: MarkLayer is built and maintained by Dean Rusin. Background, contact, editorial standards, and corrections policy for the MarkLayer site.

Registrar and domain history

Registered on Mar 18, 2026. Registrar: CloudFlare, Inc..

Recorded expiry date: Mar 18, 2027. Registry data can change.

Connection and hosting evidence

The checked homepage returned HTTP 200.

A valid TLS certificate was observed, expiring Dec 10, 2026.

Threat checks and score context

External malware-provider coverage was unavailable. The report does not treat this missing check as a clean result.

Safety Score: 70/100. Evidence Confidence: 75%. These measure different things.

Sampled scripts and pages

Resource analysis incomplete

3 resources checked · 1 script links observed on the homepage. Partial resource coverage.

ClamAV inspects the fetched homepage HTML on our server. New scans also sample up to four linked scripts and two collected internal pages, with size and time limits. Scripts are not executed. Other downloads, private server files and logged-in pages remain outside this check. A signature match needs investigation and can be a false positive. No match is not a whole-site safety guarantee.

Exact hostname lookup uses a downloaded Phishing.Database snapshot. It does not send this domain to an external lookup API or mark sibling subdomains as harmful. Not listed does not mean safe. Snapshot age is download age, not proof that every entry was recently revalidated.

Homepage HTML only · Eight local rule families · local-security-v2

Checks use the fetched page and redirect chain. Scripts are not executed, forms are not submitted, and linked files are not downloaded. This is not a malware clearance.

Page resource inventory

Linked scripts1

Counts describe the sampled HTML, not every resource loaded by the browser. External resources are common and are not automatically harmful.

No listed local patterns observed. The limited rule set cannot detect every threat or behavior.

Provider coverageNot checked

Local checks do not query external reputation databases. An unavailable check is never a clean result.

Domain email protection

Exact-host SPF and DMARC observations help the owner investigate email impersonation risks. They are separate from website malware checks and do not change the Safety Score.

SPFPolicy record observed, not fully validated
DMARCPolicy record observed, not fully validated

What to do next

Review the records with your mail administrator. Inventory legitimate senders and test SPF and DKIM alignment before enforcing a stricter DMARC policy. Fix duplicate records and investigate overly permissive SPF rules.

This bounded check does not send email, probe SMTP, evaluate recursive SPF includes, verify DKIM signatures or apply organizational-domain DMARC inheritance. A missing subdomain record does not prove that no inherited protection exists. A DNS timeout is unknown, not an absent record. A policy record is not proof that messages authenticate successfully.

Versions are shown only when publicly exposed by the page or response headers. An observed version is not, by itself, proof of a vulnerability.

JavaScript library advisories

1 sampled JavaScript files checked locally with Retire.js. Database snapshot: 2026-10-04T02:40:12.278Z.

No supported library version was identified in the sampled files. This does not establish that the scripts are safe.

A version match is not proof that the website is infected or that an issue is exploitable here. Owners should review the advisory, check whether their code is affected and test an update. Up to four external script files are sampled, not every dependency, inline script or dynamically loaded resource.

Questions about marklayer.app

FAQ

Still have questions? Contact us →
Is marklayer.app safe to visit?

The latest Safety Score is 70/100 with 75% Evidence Confidence. This is a point-in-time assessment of observed technical signals, not a guarantee. Check the exact address and avoid entering payment details if anything looks unusual.

Did the scan detect malware on marklayer.app?

ClamAV found no signature match in the sampled homepage HTML. External scripts, downloads and private server files were not checked. This is not a whole-site malware clearance.

When was marklayer.app registered?

The public registry record shows Mar 18, 2026. Registration details may be privacy-protected or updated later.

Did marklayer.app have a valid TLS certificate?

The scanner observed a valid TLS certificate using TLSv1.3. A valid certificate alone does not establish that the site is safe.

How does marklayer.app describe itself?

The website's About page describes its purpose in the report above. This is publisher-supplied information and is separate from independent security findings.

Can a paid listing change this website's score?

No. Premium placement and owner-supplied pages are labelled separately. Technical evidence, the Safety Score and moderation decisions remain independent.
