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 overleaf.com

Updated Oct 1, 2026

The latest scan examined 10 public pages on overleaf.com. 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: An online LaTeX editor that’s easy to use. No installation, real-time collaboration, version control, hundreds of LaTeX templates, and more.

Registrar and domain history

Registered on Jul 2, 2008. Registrar: Cloudflare, Inc..

Recorded expiry date: Jul 2, 2027. Registry data can change.

Connection and hosting evidence

The checked homepage returned HTTP 200 in about 1000 ms.

A valid TLS certificate was observed, expiring Nov 25, 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: 69/100. Evidence Confidence: 75%. These measure different things.

Observed security header values were checked for basic protective settings. Empty values, disabled HSTS and unrecognized values receive no credit. This is not a complete browser-policy validation. Local checks found potentially unsafe form markup or unencrypted active resources. See Automated security checks for the evidence.

Server-side analysis

Automated security checks

Local antivirus and phishing checks

ClamAV · homepage HTMLLocal antivirus is not enabled
Phishing.Database · exact hostnameLocal feed snapshot unavailable

Sampled scripts and pages

Resource antivirus is not enabled

0 resources checked · 20 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.

DNS observations · no external lookup API

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.

Questions about overleaf.com

FAQ

Still have questions? Contact us →
Is overleaf.com safe to visit?

The latest Safety Score is 69/100 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 overleaf.com?

External threat-provider coverage was unavailable for this scan, so malware status is unverified.

When was overleaf.com registered?

The public registry record shows Jul 2, 2008. Registration details may be privacy-protected or updated later.

Did overleaf.com 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 overleaf.com 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.
