Action1 Free Initial Vulnerability Assessment vs aemscan: Side-by-Side Comparison (2026)

Action1 Free Initial Vulnerability Assessment

Startups and SMBs with constrained budgets who need real vulnerability visibility without waiting for scan cycles should start with Action1 Free Initial Vulnerability Assessment; unlimited endpoint assessment plus automated patching for the first 200 machines means you're actually closing gaps, not just logging them. The private software repository hits 99% patching coverage and integrates CISA KEV data, so you're tracking what matters. This is not the tool for organizations that need vulnerability context beyond Windows and third-party apps, or teams expecting deep asset-layer remediation workflows; Action1 is deliberately focused on rapid detection and patch execution.

aemscan

Security teams managing Adobe Experience Manager instances need aemscan because it's purpose-built for AEM's specific attack surface rather than generic web app scanning; the 186 GitHub stars and free pricing mean adoption is already happening in mid-market deployments where AEM security often gets overlooked. The tool excels at identifying configuration and component vulnerabilities that automated scanners designed for other platforms will miss. Skip this if your organization runs AEM at massive scale and needs centralized inventory and remediation workflows; aemscan is a targeted scanner, not a platform.
