Scale Security Without Adding Complexity

The Invisible Layer of Smart Defense

Cyber threats evolve faster than ever, and traditional security tools often fail to keep up. DNS-level protection provides the first line of defense — invisible, fast, and effective — where threats can be blocked before they even reach your network. Sheriff DNS doesn’t just detect, it prevents. It's the smart, scalable, and cost-effective way to protect your digital environment in a world where every click matters.

What It Protects You From

DNS is your network’s first line of defense. At Sheriff DNS, we stop cyberattacks where they begin—before users ever connect to a malicious domain. Our Threat Protection solution identifies, blocks, and isolates suspicious activity at the DNS layer, ensuring a secure, uninterrupted experience across all endpoints.

Phishing and Spear Phishing

Prevent users from accessing fake login pages or malicious emails.

Malware and Ransomware

Block known malicious hosts and prevent callbacks to C2 servers.

Botnets and DDoS

Detect botnet command signals and stop compromised devices from being used in coordinated attacks.

How It Works

Understanding how Sheriff DNS protects your network starts with one core principle: security should be fast, invisible, and proactive. Our Threat Protection operates silently at the DNS layer, filtering and blocking dangerous domains before they can cause harm — all without disrupting user experience or slowing down your systems.

DNS-Level Interception

Every time a device in your network makes a request to access a website or service, Sheriff DNS inspects that request at the DNS level — the very first stop in the connection chain. This process happens before the request reaches the internet, which allows us to detect and block threats immediately, rather than reacting after the fact. Even the fastest phishing or malware attacks are neutralized in milliseconds. Since this happens upstream from the browser, there's no need to install endpoint software or hardware devices.

Real-Time Intelligence

We continuously monitor and update our system with live data from global threat intelligence sources, combined with our own AI-driven analysis. Each DNS query is checked against millions of known malicious, suspicious, and newly registered domains. This allows us to catch zero-day threats and fast-moving attack campaigns, including those that change IP addresses or use dynamic domain generation. You’re always protected — not just from yesterday’s attacks, but today’s and tomorrow’s.

Policy-Based Control

Sheriff DNS allows IT administrators to define flexible access policies tailored to their organization's needs. You can create user groups, assign rules based on department or device type, and enforce access restrictions for risky categories (e.g., adult content, gambling, newly registered domains). Whether you're managing a corporate environment or a distributed remote team, you maintain full control over how the internet is accessed — and by whom.

Threat Containment

If a DNS query is flagged as malicious or falls outside your defined policies, it is immediately blocked. The user sees a customizable block page, and the event is logged and sent to your dashboard in real-time. Suspicious behavior is isolated and prevented from escalating into larger breaches, such as lateral movement or exfiltration. This allows your security team to respond early — before an incident becomes a disaster.

Frequently Asked Questions

Find quick answers to the most common questions about our DNS protection, integration process, and security capabilities.

What is DNS protection, and why do I need it?

DNS protection is a security measure that safeguards the Domain Name System (DNS), which translates website names into IP addresses, from cyber threats. You need it because DNS is a common entry point for attacks like phishing, malware, and DDoS, especially for small businesses with limited cybersecurity resources. It acts as a first line of defense by filtering out malicious traffic before it reaches your network, protecting sensitive data and ensuring business continuity.

How does Sherrif DNS differ from other security solutions?

Sherrif DNS stands out by offering specialized DNS-layer security tailored for both small businesses and enterprises, focusing on simplicity and efficiency. Unlike broader security solutions that may require complex hardware or extensive IT support, Sherrif DNS provides a lightweight, cloud-based approach that integrates easily without significant overhead. It emphasizes real-time threat blocking and scalability, distinguishing it from traditional firewalls or antivirus software that target different attack vectors.

Is Sherrif DNS suitable for small businesses or just enterprises?

Sherrif DNS is suitable for both small businesses and enterprises, thanks to its flexible deployment and cost-effective design. Small businesses benefit from its easy setup and robust protection against common threats like malware and phishing, without needing a dedicated IT team.
