Compare features, ratings, integrations, and community reviews side by side to find the best external attack surface management fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams running manual subdomain discovery workflows or evaluating attack surface management on a budget should start with Subra; it wraps the open-source subfinder tool in a web interface that cuts the friction of command-line enumeration without requiring infrastructure spend. The 54 GitHub stars and free pricing model mean you can validate subdomain coverage gaps in minutes, not weeks of vendor evaluation. Skip this if you need continuous monitoring, prioritization scoring, or integration with your existing vulnerability management stack; Subra is a one-time discovery tool, not a platform.
Ceeyu Digital Footprint Monitoring
Mid-market and enterprise security teams struggling to find rogue cloud instances, forgotten domains, and shadow IT before attackers do should start with Ceeyu Digital Footprint Monitoring; it automates the tedious work of external asset discovery that most teams do manually or skip entirely. The tool maps directly to NIST ID.AM and ID.RA, meaning you'll actually close the visibility gap that precedes every breach, not just monitor what you already know exists. Skip this if your organization has mature threat intelligence operations and systematic cloud governance; Ceeyu solves the "we don't know what we don't know" problem, not the "we need advanced correlation" problem.
