Mid-market and enterprise security teams drowning in unknown external assets will find immediate value in Anomali Attack Surface Management's discovery engine, which maps your entire digital footprint across domains, cloud, SaaS, and hardware without requiring agent deployment. The platform's continuous monitoring paired with risk-based prioritization means you stop chasing every vulnerability and focus on what actually exposes you to attack; its integration with Anomali Match Cloud threat intelligence directly connects your surface to known adversary tactics. This tool assumes you have the resources to act on what it finds, so lean security ops teams relying on a small contractor to handle external risk should look elsewhere. Security teams doing threat intelligence or domain monitoring should use crt.sh as a free, fast way to spot certificate issuance anomalies that signal domain takeover or phishing campaigns before they scale. Certificate Transparency logs index roughly 15 billion certificates, giving you real-time visibility into what's been legitimately issued against your domains and competitors' infrastructure. Skip this if you need automated alerting or integration into your SIEM; crt.sh is a lookup tool, not a monitoring platform, and catching malicious certificates requires manual checks or custom scripting.
