CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Startups and individual security practitioners who need granular per-application network control without licensing friction should use Safing Portmaster; it's free, open-source, and runs locally so you own the ruleset and logs. The tool covers NIST DE.CM continuous monitoring of network anomalies and PR.IR infrastructure resilience through application-level firewall rules, kill switch, and encrypted DNS, giving you visibility most OS firewalls skip. Skip this if your team expects vendor support, cloud-native orchestration, or centralized policy management across dozens of endpoints; Portmaster is single-machine focused and backed by a two-person team in Austria.
Startups and SMBs protecting web applications on tight budgets should evaluate SafeLine WAF for its free pricing and machine learning-based attack detection without custom rule limits. The open-source model eliminates licensing friction while covering HTTP flood DDoS, bot filtering, and geo-blocking across cloud deployments. Skip this if you need post-breach forensics or incident response automation; SafeLine prioritizes detection and blocking over the visibility and recovery capabilities that enterprises typically require.
