DNS security
The challenge
Your organization relies on the Domain Name System (DNS) to translate domain names into IP addresses, making it a critical infrastructure component. However, DNS is also a prime target for cyberattacks, which can lead to data breaches, service disruptions, and financial losses. Traditional security measures often fail to protect against sophisticated DNS-based threats. The cost of neglecting DNS security can be significant, impacting your organization\''s reputation and bottom line. You need a robust DNS security solution to protect your infrastructure and maintain business continuity.
Learn moreThe solution
DNS security addresses your unique challenges through modern solutions and key capabilities.
AI-driven behavioral detection
Modern solutions use behavioral models to identify DNS tunneling and zero-day malware patterns, going beyond static blocklists.
Infrastructure resilience and DDoS mitigation
Solutions provide a global Anycast network with built-in traffic scrubbing to ensure DNS service availability during high-volume attacks.
Encrypted protocol support (doh, dot, doq)
Full support for DNS over HTTPS, TLS, and QUIC is essential for protecting user privacy and preventing intercept attacks.
Granular filtering for zero trust
Solutions allow policies to be set based on the specific identity of a user or device, rather than just their IP address.
Ecosystem orchestration (SIEM/SOAR/NAC)
The DNS layer automatically shares threat data with SIEM systems and triggers automated quarantines in SOAR platforms.
"hybrid engine" resilience
DNS appliances can switch between different software engines in real-time to mitigate zero-day vulnerabilities in a specific protocol implementation.

How to evaluate DNS security
Deployment flexibility
Evaluate whether the vendor supports a hybrid cloud strategy to avoid blind spots as enterprises migrate workloads.
Integration maturity
Ensure the solution can ingest data from your existing Identity Provider (IdP) and export logs to your SIEM via high-speed APIs.
TCO beyond the license
Account for change management and training costs, which can often exceed the Year 1 license fee in complex environments.
Performance slas
Verify the vendor provides an SLA not just for uptime, but for resolution latency to avoid user experience degradation.
Questions to ask suppliers
Use these questions during supplier evaluations to ensure you're choosing the right partner for your needs.
DNS security RFP guide- How does your behavioral detection engine differentiate between a legitimate high-entropy query and a DNS tunneling attempt?
- Can you provide a walkthrough of your automated DNSSEC key rollover process and explain how you ensure the DS record in the parent zone is synchronized without manual intervention?
- What specific percentage of your threat intelligence is generated from your own proprietary sensor network versus third-party open-source feeds?
- In a "worst-case" scenario where your cloud resolution network is under a volumetric DDoS attack, what emergency fail-safe mechanisms do you provide to ensure my local users can still access internal resources?
