Side by side

What it does

A network-wide DNS server that blocks ads and trackers, with encrypted DNS support, per-client settings and a web dashboard.

Cloud DNS-layer security that blocks malicious and unwanted domains for offices and roaming laptops, extending to secure web gateway and firewall features.

Watch out

DNS blocking cannot stop ads served from the same domains as content.

Higher tiers get expensive and are being folded into Cisco's wider security bundles.
