CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams managing polyglot codebases across GitHub, GitLab, and container registries should pick Aikido EOL Scanner because it detects unsupported dependencies before they become compliance violations or attack surface. The tool maps EOL components to internet-exposed runtime instances, which forces prioritization conversations your team actually needs to have instead of drowning in dependency reports. Skip this if your organization runs a single language stack or hasn't integrated version control and container scanning into your asset inventory yet; Aikido's value compounds with deployment complexity.
Security teams hunting subdomain takeover vulnerabilities before attackers find them should use second-order, a free scanner that catches dangling DNS records pointing to unclaimed hosting services. The tool has 408 GitHub stars and zero friction to deploy; it's built to run locally or in CI/CD without vendor lock-in. Skip this if you need a full attack surface management platform covering certificate transparency logs, WHOIS changes, and passive reconnaissance; second-order does one job and does it fast.
