# Which DNS security solution is best for preventing phishing and data exfiltration at the DNS layer before anything even hits the endpoint?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Here is the question I set out to answer: which DNS security solution is best for preventing phishing and data exfiltration at the DNS layer before anything even hits the endpoint? The appeal of DNS-layer enforcement is that it stops a threat at the point of resolution, before the connection is made and before your endpoint tools have to react. Reviewers in the <a class="a a--md" elv="true" href="https://www.g2.com/categories/dns-security-solutions">DNS security solutions</a> category point to DNSFilter, Cisco Umbrella, and Cloudflare most often, with ScoutDNS a common pick for smaller teams.</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/dnsfilter/reviews"><strong>DNSFilter</strong></a>: Enterprise reviewers describe it as stopping threats at the DNS level before a connection is ever made, reducing security incidents and helpdesk tickets. Users also call it a layer that operates before EDR or antivirus can intervene. Its machine-learning classification is designed to catch phishing and malware domains early.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/cisco-umbrella/reviews"><strong>Cisco Umbrella</strong></a>: Reviewers describe it as proactively blocking malicious domains, phishing, and malware at the DNS layer, before they reach the network, and backed by Talos threat intelligence.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/cloudflare-application-security-and-performance/reviews"><strong>Cloudflare Application Security and Performance</strong></a>: Through its Gateway and Zero Trust features, reviewers filter traffic and secure access before it reaches infrastructure, with bot and threat controls enforced at the edge.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/scoutdns/reviews"><strong>ScoutDNS</strong></a>: Built as a protective DNS solution that blocks malicious domains and shadow IT at the DNS layer before they reach endpoints, using a lightweight agent. Its reviewers are mostly MSPs and smaller IT teams.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">If you moved phishing defense to the DNS layer, did it actually reduce what reached your endpoint tools, and where did it fall short on newer or fast-rotating domains?</p>

The claim worth testing in a proof of concept is the one DNSFilter reviewers keep making: fewer incidents reaching EDR and fewer helpdesk tickets once DNS-layer blocking went in. That&#39;s measurable in your own environment inside a month. Where reviews go quiet is exactly where you&#39;d worry, newly registered and fast-rotating domains. DNSFilter&#39;s machine-learning classification and Umbrella&#39;s Talos feed both exist for that gap, but I haven&#39;t seen either review base claim it&#39;s closed. I&#39;d run whichever tool in log-only mode against a week of real traffic and count what it would have caught before trusting anyone&#39;s numbers.
