## What the models said for it

- "Need company-wide policy enforcement? Cisco Umbrella or Cloudflare Gateway." (GPT-5.4 mini, DNS filtering)
- "Quad9 and OpenDNS are the best DNS providers when blocking access to known phishing sites and malware sources" (Claude Haiku 4.5, Managed DNS)
- "Best for: Small businesses, families, and education." (Grok 4.20, DNS filtering)

## And against it

- "Avoid free/public options (e.g., Quad9, OpenDNS basic) for B2B" (Grok 4.20, DNS filtering)
- "Cisco's enterprise ties raise surveillance concerns. Logs queries ... Use only if you need its filtering dashboard and accept the trade-offs." (Grok 4.20, DNS filtering)
- "often has minimums (e.g., $380+/year for small business)... though it's being phased toward Umbrella's higher-tier offerings" (Grok 4.20, DNS filtering)
- "Why to be cautious: After being acquired by Cisco, OpenDNS faced significant privacy criticism." (Qwen 3.7 Flash, DNS filtering)
