What is this website?

Free, client-side SIP analyzer. Drop a PCAP, PCAPNG, sngrep log, tshark or tcpdump export to render the call flow ladder, surface RFC issues, play back RTP audio, decode T.38 / T.30 faxes to TIFF, and (opt-in) ask a SIP-specialist AI to explain what went wrong. A Wireshark SIP viewer that runs in your browser. Plus an MCP server for Cursor, VS Code, Claude, and Codex.

Registrar and domain history

Registered on Apr 19, 2026. Registrar: CloudFlare, Inc..

Recorded expiry date: Apr 19, 2027. Registry data can change.

Connection and hosting evidence

The checked homepage returned HTTP 200 in about 2000 ms.

A valid TLS certificate was observed, expiring Nov 14, 2026.

Threat checks and score context

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

Sampled scripts and pages

Resource analysis incomplete

6 resources checked · 13 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.

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

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
DMARCMultiple policy records need review

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.

Responsible disclosure

security.txt

RFC 9116 observation

No readable security.txt file was observed at the standard locations. This is informational and is not evidence of malware.

Browser protections

Security headers

Header evidence is unavailable. Missing data is not treated as a clean result or proof of compromise.

Response headers

Passive observation

No Set-Cookie header was observed on the sampled homepage response. Other pages may set cookies separately.

Bootstrap 80% Cloudflare 98% Google Analytics 94% Next.js 96% Tailwind CSS 72%

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

4 sampled JavaScript files checked locally with Retire.js. Database snapshot: 2026-10-11T02:40:11.666Z.

react-dom 19.3.0-canary-3f0b9e61-20260317 No known advisories matched this version in the database snapshot.

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 sipflow.dev

FAQ

Still have questions? Contact us →
Is sipflow.dev safe to visit?

The latest Safety Score is 66/100 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 sipflow.dev?

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 sipflow.dev registered?

The public registry record shows Apr 19, 2026. Registration details may be privacy-protected or updated later.

Did sipflow.dev 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.

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.
