ACE-powered DNS security for egress control.
DNS Shield evaluates destination infrastructure at resolution time so teams can stop outbound connections to malicious, suspicious, or policy-disallowed infrastructure before sessions are established. It gives security teams a practical way to move FraudGuard intelligence closer to the egress path instead of waiting for downstream tooling to clean up the damage.
What it is built to stop
Malware callbacks, phishing destinations, command-and-control infrastructure, hostile automation endpoints, and other destinations that should never receive an outbound connection from your environment.
Why teams buy it
DNS Shield lets organizations make destination-aware decisions earlier, reduce downstream security noise, and enforce egress policy at a layer every workload already touches.
Why DNS becomes a powerful security control
Every outbound workflow eventually needs a destination. DNS Shield turns that universal control point into a high-signal enforcement layer for environments that care about egress protection, containment, and early destination blocking.
Block risky infrastructure early
Prevent connections from ever reaching hostile destinations instead of waiting for downstream web proxies, EDR, or incident response to catch up later.
Protect broad egress surfaces
Cover users, servers, cloud workloads, and other systems that already depend on recursive DNS to reach external infrastructure.
Reduce downstream security noise
Cut wasted telemetry and alert volume by stopping known-bad destinations at resolution time instead of letting every control stack see them later.
Choose the right enforcement path
Use DNS policy to deny, redirect, or sinkhole based on how you want to handle categories of malicious or suspicious infrastructure.
How DNS Shield fits into the environment
DNS Shield is built for organizations that want recursive DNS to become part of their enforcement path, not just a background resolver. FraudGuard intelligence can be used to evaluate destination infrastructure as names are resolved so your environment can stop high-risk destinations earlier and more consistently.
That is useful for egress filtering, malware containment, phishing infrastructure blocking, internal fleet security, and cloud environments where outbound controls need to be both fast and operationally predictable. Instead of forcing every enforcement decision into a later stage, DNS Shield helps teams push the decision closer to the first network dependency.
Because operating models vary, DNS Shield is scoped around deployment flexibility. Some organizations want a hosted approach, others want customer-managed control paths, and others need alignment with existing recursive DNS or policy-zone tooling.
Threat-aware recursive resolution
Bring FraudGuard intelligence into recursive DNS decisioning so destinations can be evaluated before a connection leaves the environment.
Sinkhole and redirect options
Choose the operational response that makes sense for containment, user safety, or investigative visibility.
Customer policy in the loop
Blend FraudGuard intelligence with your allowlists, internal exceptions, and deployment-specific enforcement policy.
Built for egress-sensitive environments
Support organizations that care about outbound control, security architecture review, and predictable DNS-layer operations.
How DNS Shield decisioning works
DNS Shield is designed around an operationally simple sequence: resolve the name, evaluate the destination, apply policy, and keep evidence available for security and infrastructure teams.
Receive the DNS request
Capture the destination lookup at the recursive DNS layer where every outbound workflow already begins.
Evaluate destination risk
Use FraudGuard intelligence and environment policy to determine whether the destination should be allowed, denied, redirected, or sinkholed.
Apply enforcement
Return the response that matches your enforcement model without forcing a separate downstream control to make the first decision.
Retain operational visibility
Give infrastructure and security teams enough evidence to explain why the destination was challenged and how policy should evolve.
What can inform a DNS Shield decision
DNS Shield is not just a static domain blocklist. It is built to make destination decisions using richer context around risk, infrastructure, and policy.
ACE destination intelligence
Evaluate whether the destination is tied to malicious or suspicious infrastructure observed by FraudGuard.
IP and hostname reputation
Use destination reputation context to decide whether the name should resolve normally or be stopped early.
Customer allow and deny policy
Preserve internal business logic, partner exceptions, and organizational policy in the same decision path.
Sinkhole-worthy infrastructure
Divert destinations that should never be reached so containment and observation can happen cleanly.
Threat campaign context
Escalate destinations that are part of broader hostile infrastructure rather than isolated single indicators.
Egress posture tuning
Adjust enforcement strictness to match your environment, false-positive tolerance, and security architecture.
Best-fit DNS Shield deployments
DNS Shield is a strong fit for environments where outbound network control, malicious-destination blocking, and early enforcement matter more than adding another passive feed.
Corporate egress security
Protect employee traffic and enterprise network egress by blocking destinations that should never be reachable from managed environments.
Cloud and workload containment
Reduce the chance that compromised workloads can communicate with hostile external infrastructure during later-stage activity.
Security teams standardizing controls
Give architecture and platform teams a reusable DNS-layer enforcement path that complements firewalls, proxies, and endpoint tooling.
Design a DNS-layer security posture that is actually informed by threat intelligence
If you want recursive DNS to become a meaningful egress control instead of a passive utility, DNS Shield is the right conversation. FraudGuard can scope the deployment model, policy approach, and intelligence path to fit the environment you already operate.
