Total DNS Visibility. No Blind Spots. No Guesses.

Most security tools give you surface-level noise. Control D lets you log and inspect every DNS query across your organization.

Know what devices are doing, spot threats before they escalate, and prove compliance when it matters.

What you get with DNS logging in Control D

Historical stats that actually help
Full visibility into DNS traffic patterns across time. Identify top domains, usage trends, and previously-blocked threats. Use it for threat hunting, policy review, or just to understand what’s really happening inside your network.
Real-time streaming to your SIEM
No delays. No guesswork. Stream live DNS logs into your existing SIEM and respond to events as they happen. Works with your existing stack—because nobody wants another black-box dashboard.
Choose where your data lives
Store your logs in a jurisdiction of your choice. Whether you need to comply with GDPR, HIPAA, or just internal policy, Control D gives you control over data residency and retention.
Actionable, not decorative
We don’t give you pie charts for the sake of looking smart. Our insights let you detect anomalies, enforce policy, and take proactive action — instead of cleaning up after a breach.
The logging and analytics capabilities have transformed how we monitor and secure our client networks—visibility we never had before.

Frequently asked questions

No. Logging is 100% opt-in. If you don't enable it, nothing is stored — not temporarily, not silently, not at all. When it's on, you choose what gets logged, how long it's kept, and where it's stored.

Yes. You can choose where your logs are stored, including privacy-forward regions like Canada or the EU. This helps you meet compliance requirements like GDPR, HIPAA, and internal data residency policies.

Yes. Control D supports real-time log streaming to SIEMs like Splunk, ELK, and others via syslog or webhook. You get structured, JSON-formatted logs — no extra parsing required.

Minimal. Logging happens server-side and doesn't slow down end-user queries. Your network won't notice — but your security team will.

Yes. You can enable logging per network, user group, device, or policy. Log everything or just high-risk segments — your call.

Yes. Logs include device, user, and network context so you know who made the query, not just what they queried.

When enabled, we log DNS queries (domain names), timestamps, device/user IDs, network metadata, and action taken (allowed/blocked). No content, payloads, or personal info outside of what's needed for attribution.

Yes. You control logging, retention, jurisdiction, and data flow. Control D is built with zero trust principles and supports strict policy enforcement. You'll stay on the right side of legal and internal audit.

Of course. Logging can be toggled off instantly. Data stops flowing, and you can purge existing logs on demand.
