The DNS Line of Defense: Why EnforceDNS is Your Network’s Safety Net

When high-profile breaches and sophisticated typhoon state-sponsored attacks dominate the headlines, they serve as a sobering reminder: even the most well-funded organizations can be compromised. At threatER, we know that modern cybersecurity cannot afford to be static. In an era of relentless threats, your defense-in-depth strategy is only as strong as its most overlooked layer: DNS.

With our specialized EnforceDNS (powered by our strategic partnership with HYAS), we provide the critical layer of protection that catches what others miss.

Why Multiple Layers Matter

Modern threat actors are persistent, leveraging a mix of technical exploits and human error. No single tool, not even a high-end Firewall or EDR, is a silver bullet. This is why a defense-in-depth posture is non-negotiable.

EnforceDNS acts as both your scout and your final sentry. Even if an attacker manages to bypass your perimeter or trick a user into clicking a link, our DNS-layer enforcement stops the communication in its tracks before the damage is done.

EnforceDNS: The First and Last Line of Defense

The Domain Name System (DNS) is the backbone of internet communication. By inspecting every single DNS transaction in real-time, threatER EnforceDNS protects your organization from the inside out:

• Proactive Content Filtering: As a first line of defense, we eliminate risk by blocking access to non-work-related categories like gambling, weapons, or known high-risk domains
• Neutralizing Phishing: We block malicious domains before the page even loads, preventing credential theft at the source
• Stopping “Drive-By” Downloads: We prevent users from unknowingly pulling malware onto your network from compromised sites
• Severing Command-and-Control (C2): This is the “last line” of defense. If a device is infected, EnforceDNS kills the connection to the attacker’s server, preventing them from sending instructions or moving laterally
• Thwarting Data Exfiltration: We detect and block abnormal DNS requests used by attackers to smuggle sensitive data out of your environment

The Myth of Speed vs. Security

Some providers prioritize raw DNS resolution speed above all else. At threatER, we believe that security is worth the millisecond.

While EnforceDNS provides the low-latency experience users expect, we refuse to sacrifice inspection for the sake of a fraction of a second. It takes a moment to evaluate the legitimacy of a domain against our massive infrastructure intelligence. This negligible trade-off, often imperceptible to the end-user, is the difference between a normal workday and a catastrophic ransomware event.

The Trade-Off is Clear:

• Blocking one phishing domain can save an entire enterprise
• A millisecond of inspection is a small price to pay to stop a data breach that could cost millions

Beyond Blocking: Actionable Intelligence

EnforceDNS doesn’t just set and forget. It equips your security team with deep visibility into network behavior:

• Suspicious Site Tracking: Identify compromised devices by spotting anomalies in outbound requests
• Identifying High-Risk Behavior: Pinpoint users who repeatedly hit unsafe domains to provide targeted training or uncover potential insider threats
• Threat Trend Analysis: Monitor recurring malicious patterns to proactively refine your security posture

Building Resilience with threatER

Individual layers of your security stack will eventually fail. When they do, you need a layer that functions as both a shield and a fail-safe. threatER EnforceDNS mitigates risk across every form of cyberattack that requires internet communication.

It’s easy to deploy, integrates seamlessly with your existing stack, and keeps your business moving at the speed of the cloud securely.
