letsencrypt.org

The available scan data is broadly reassuring at the time of this scan. The domain was not flagged by any of 92 security engines, and the checked blacklist databases reported clean results. The site is also well established, with a domain age of more than 11 years and a strong web presence, which tends to be more consistent with a legitimate long-running service than with short-lived abuse domains.

One malware scan did produce a generic "suspicious" result and marked multiple pages and a few referenced links with low-specificity heuristic labels. However, the flagged items appear to include normal documentation pages, language variants, technical references, and external resources related to ACME and internet infrastructure. In the absence of corroboration from other security engines or blacklist systems, these findings may reflect heuristic false positives rather than confirmed malicious behavior.

Based on available data, no threats were detected at the time of this scan, and the isolated heuristic alerts appear low confidence. Overall, this website appears to present a low risk profile at the time of review.
