Domain Due Diligence
Report for Transunion.com
Β Why we think so?Β
transunion.com is the official site of TransUnion, one of the three major U.S. credit bureaus. The site shows strong authenticity signals: ~7.1M monthly visits, an enterprise technology stack (Adobe, Cloudflare, Fastly, Google Analytics), valid TLS from Entrust, multiple DNS TXT verifications, official newsroom coverage, and legitimate contact emails and phone numbers. However, TransUnion has a history of regulatory actions, a notable 2023 data breach affecting millions, and many consumer complaints β and a low Google Places rating (1.2/5) in one local listing. Verdict: proceed with caution β the site is legitimate, but protect sensitive data and watch for phishing attempts that impersonate TransUnion. π‘οΈ

π Detailed Checks & Analysis
Domain age & registrar
Score: 90/100
Domain age & registrar
"Whois data indicates corporate registration and stable name servers (pdns1/2.cscdns.net), reducing the likelihood this is a throwaway scam domain."
Reason: Domain is long-established and registered through a corporate registrar (CSC), which is typical for large enterprises.
Traffic and audience signals
Score: 92/100
Traffic and audience signals
"SimilarWeb reports ~7.1M monthly visits and ~95% U.S. audience share, which strongly supports authenticity."
Reason: Very high monthly visits and major brand keywords ("transunion", "transunion login") match expectations for an authoritative credit bureau site.
Tech stack and site infrastructure
Score: 88/100
Tech stack and site infrastructure
"Presence of multiple vendor verifications (Google, Atlassian, Box, Fastly) and a corporate CDN suggests professional site management."
Reason: The site runs enterprise systems (Adobe Experience Manager, Cloudflare, Fastly) and has many verification TXT records, indicating legitimate, managed infrastructure.
SSL / browser safety
Score: 90/100
SSL / browser safety
"TLS valid from 2025-09-15 to 2026-09-15; absence of active Safe Browsing matches indicates no known active phishing on the domain."
Reason: Valid Entrust OV certificate for www.transunion.com and no Google Safe Browsing flags were detected.
Contact details and ownership signals
Score: 85/100
Contact details and ownership signals
"Multiple contact emails and corporate social profiles (Twitter, LinkedIn, YouTube) reduce the chance this is an impersonation page."
Reason: Public customer support phone number and official emails (e.g., truvalidate@transunion.com) are present in site-scraped contacts.
Blacklist & phishing checks
Score: 92/100
Blacklist & phishing checks
"Scanners did not flag the domain for phishing or crypto-scams at the time of checking."
Reason: No matches on crypto scam blacklists and Google Safe Browsing returned clean results for the domain.
Trademark / brand impersonation risk
Score: 40/100
Trademark / brand impersonation risk
"USPTO query returned zero direct matches for the supplied query string; still, criminal actors commonly mimic established brands β treat unsolicited contacts cautiously."
Reason: No USPTO trademark search results were returned for the exact query, but brand impersonation risk remains due to many known phishing campaigns that impersonate TransUnion.
Reputation & news / legal history
Score: 50/100
Reputation & news / legal history
"CFPB enforcement actions and class-action litigation (TransUnion v. Ramirez) plus breach reporting mean consumers face real risks around data and dispute resolution."
Reason: Recent regulatory actions, legal cases, and a notable data breach harm reputation even though they don't make the site itself fraudulent.
Your Next Steps
-
1
Verify links and emails: use the contact phone number on the site (or the phone in the WHOIS/contacts data) rather than any number in unsolicited messages.
-
2
Do not submit Social Security numbers, full SSNs, or bank account details over forms unless you initiated the session and confirmed TLS (check the Entrust certificate and domain).
-
3
Watch for phishing: compare sender addresses and domains against the official emails found on the site (e.g., truvalidate@transunion.com) and report impersonations to the FTC.
-
4
Monitor credit reports and freeze/unfreeze options through official TransUnion pages; consider a credit freeze if you suspect identity theft.
-
5
Check recent news and regulator pages before major decisions: confirm any offers, subscriptions, or disputes via TransUnionβs official newsroom or regulated filings.
