Enterprise-grade DNS filtering at the resolver level — malware, phishing, ad networks and botnet command-and-control, stopped before a single packet reaches your devices. No hardware. No software to install.
Every DNS query from your network is checked against live threat intelligence — and logged for full visibility.
Curated blocklists (ads, trackers, malware, phishing) enforced via BIND RPZ at the resolver. Updates refresh weekly, with per-client override control.
Devices quietly checking in with command-and-control servers get flagged automatically — high NXDOMAIN rates and DGA-style patterns trigger alerts before the infection spreads.
Block or flag DNS traffic by geography — shut down lookups to high-risk regions with per-policy granularity.
See every device on your network by its DNS fingerprint — including abandoned, end-of-life firmware that will never be patched.
Per-network stats: top domains, blocked queries, query volume, alert history. SIEM export (JSON/CEF/syslog) for business plans.
Point your router at the SYLAR resolver. That's the entire setup — works with any device, any OS, from smart TVs to servers.
Set your network's DNS to the SYLAR resolver (or per-device). We register your network as a protected client.
Malware, phishing, and ad lookups are refused at the resolver. Botnet C2 check-ins get flagged and alerted.
Live stats for your network: what's blocked, what's talking, and what needs attention — updated every minute.
