Mandiant Attack Surface Management
Mid-market and enterprise security teams need continuous visibility into internet-facing assets before attackers do, and Mandiant Attack Surface Management delivers automated discovery and monitoring at scale with multicloud integration that actually works. The tool maps your external footprint daily and flags exposures without requiring manual asset feeds, which is where most ASM tools fail in hybrid environments. Skip this if you're looking for remediation workflows or patch management; Mandiant finds the problem and hands it off to you.
Security teams responsible for internet-facing infrastructure need Shodan to find what attackers see before attackers do. The free tier gives you real-time visibility into your own exposed devices, services, and default credentials across millions of internet scans without licensing friction. Skip this if your organization lacks the operational discipline to act on what you find; Shodan surfaces problems faster than most teams can remediate them, which creates noise without a triage process in place.
