trello.com Overview

Description of trello.com

Trello appears to be a web-based productivity and collaboration platform focused on task management, project planning, and team organization. The homepage messaging, metadata, and category labels indicate that it offers tools such as boards, inboxes, planners, automations, and integrations intended to help individuals and teams track work from anywhere.

Based on the branding shown in the screenshot and the referenced domains, the service appears to be operated within the Atlassian ecosystem. The site presents itself as a mainstream software-as-a-service platform for business and personal productivity, with navigation for features, solutions, plans, pricing, enterprise offerings, and customer resources. Its strong web presence and high traffic ranking are also consistent with an established technology product.

Safety Assessment for trello.com

The scan results are broadly reassuring at the time of this scan. No detections were reported by 0 out of 91 security engines, the malware scan reported no flagged files among 25 scanned items, and blacklist checks were reported as clean across the listed databases. Multiple web-classification sources also categorize the domain as information technology, business, productivity, or web collaboration, which aligns with the visible content.

One referenced domain, www.atlassian.design, was noted by the malware scan as a generic suspicious object. However, this appears to be an associated Atlassian-related domain rather than a direct indication that trello.com itself is serving malicious content. Given the domain's long registration history, strong reputation signals, and the absence of broader detection activity, this isolated reference does not materially outweigh the otherwise clean findings.

Based on available data, no threats were detected at the time of this scan.

Technical Description

The site is using a valid SSL/TLS certificate issued for Amazon infrastructure, with an expiry date in 2026-11-04, and it is served through AWS CloudFront with an AtlassianEdge web server. The observed server IP resolves to CloudFront infrastructure, which is commonly used for global content delivery and performance. DNSSEC is enabled and signed, which may help strengthen DNS integrity.

From an infrastructure perspective, the domain appears mature and professionally managed: it has been registered since 2004, uses a major corporate registrar, and relies on AWS nameservers and CDN services. No major technical security concerns are evident from the provided scan data beyond the single generic suspicious reference tied to an Atlassian-associated domain.
