Features, pricing, ratings, and pros and cons, compared head to head.
Safing Portmaster is a free next-gen firewalls tool by Safing. SonicWall Gen 8 TZ Series Next-Generation Firewall (NGFW) is a commercial next-gen firewalls tool by SonicWall. Compare features, ratings, integrations, and community reviews side by side to find the best next-gen firewalls fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
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. SMBs and branch offices that need encrypted traffic inspection without choking on overhead should start here with the SonicWall Gen 8 TZ Series; its RTDMI engine handles TLS/SSL decryption at wire speed where competitors force a performance tradeoff. Zero-Touch Deployment cuts your rollout time from weeks to days, and the integrated SD-WAN piece means you're not buying a separate overlay network just to connect branch sites. Skip this if you're enterprise-scale or need SIEM-grade forensics; the centralized management works for 10-20 sites, not 200, and this prioritizes active threat blocking over historical incident reconstruction.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
