Website Screenshots
cleanup.app scores 63/100 and is classified as suspicious. The site uses a valid TLS 1.3 certificate issued by R13 (Let's Encrypt) with 48 days remaining, but the HTTP response is 403 and the request redirects to domains.atom.com, which is a major trust concern.
SSL Certificate & HTTPS Security
cleanup.app does have a valid SSL certificate, and the connection uses TLSv1.3 with HSTS enabled. The certificate is issued by R13 (Let's Encrypt) and expires in 48 days, which confirms the site supports encrypted transport.
That said, HTTPS alone does not make a site safe. The scan also found missing security headers, specifically Content Security Policy (CSP) and X-XSS-Protection. Those gaps reduce browser-side protection against injection and cross-site scripting attacks, especially on a domain with no established reputation.
Threat Intelligence Results
The threat checks are mixed, but the overall picture is still concerning. Google Safe Browsing is clean, URLhaus is clean, and DNS blocklists from Spamhaus and SURBL are also clean. No active malware or phishing payload was confirmed in the scan.
Even with those clean results, the domain still received a suspicious verdict. The scanner AI flagged the name as a generic, potentially malicious pattern, and the domain category is listed as Unknown � suspicious pattern. The combination of an unfamiliar domain, weak reputation, and a 403 response is enough to justify caution.
Domain History & WHOIS Analysis
The domain has no registrar data available, and the creation date is unknown. That means there is no clear ownership or age signal to support trust, which is a problem for a site that offers no recognizable brand identity.
The scanner also marks the domain as not known, with domain reputation listed as unknown. The lack of WHOIS visibility, combined with a generic name like cleanup.app, matches the red-flag pattern noted in the scan: a domain that can be used for malicious cleanup scripts or malware-related activity without any established public reputation.
Is Cleanup.app Legitimate?
The site does not present enough evidence of legitimacy to trust it. The final HTTP status is 403 Forbidden, and the redirect chain ends at https://domains.atom.com/lpd/name/Cleanup.app, which does not match a normal public service flow.
A legitimate service should have a clear identity, accessible content, and a stable reputation. cleanup.app has none of those signals in the scan data, so the safest conclusion is that it is not safe to trust without strong external verification.

Frequently Asked Questions
is cleanup app safe?
No. cleanup.app received a 63/100 suspicious score, returned HTTP 403, and redirected to domains.atom.com. While the SSL certificate is valid, the domain has no established reputation and missing security headers.
Does cleanup.app have a valid SSL certificate?

Was cleanup.app flagged by malware or phishing blocklists?
No active blocklist hit was found. Google Safe Browsing, URLhaus, Spamhaus, and SURBL all returned clean results. That does not override the suspicious verdict from the domain�s behavior and reputation signals.
Why is cleanup.app rated suspicious if the blocklists are clean?
Because the scan found multiple trust issues: a 403 Forbidden response, a redirect to domains.atom.com, missing CSP and X-XSS-Protection headers, unknown domain age, and no registrar data. Those signals outweigh the clean blocklist checks.
Is cleanup.app a known legitimate brand?
No known brand or recognized service was identified in the scan. The domain is marked as unknown, with unknown reputation and a generic name that fits a suspicious pattern.
