DNS Security
What Is DNS Security?
Your network talks to the internet constantly, every click, login, and application request starts with DNS. If that traffic isn’t controlled, it can quietly connect to malicious or suspicious destinations. DNS security ensures your internet traffic only goes where it should. By filtering and monitoring DNS requests in real time, businesses can block access to known malicious domains before a connection is ever established, prevent users and devices from reaching risky networks, reduce exposure to ransomware, phishing, and command-and-control attacks, and gain clear visibility into where traffic is going across the organization.
Frequently Asked Questions
What happens if DNS traffic isn’t secured?
Unsecured DNS traffic can allow users and devices to connect to malicious websites without detection. This is often how ransomware, phishing attacks, and malware infections begin before traditional security tools can intervene.
How does DNS security stop cyber threats?
DNS security blocks connections to known malicious domains before a connection is established. This prevents users from reaching harmful destinations, reducing the risk of infection, data loss, and unauthorized access.
Is DNS security enough on its own?
No. DNS security is one layer of a broader cybersecurity strategy. It works best alongside endpoint protection, email security, and multi-factor authentication to create a layered defense.
Does DNS security protect remote and mobile users?
Yes. DNS security can be applied across devices and locations, helping protect remote and hybrid work environments where users are outside the traditional network perimeter.
How quickly does DNS security respond to threats?
DNS security operates in real time. It evaluates requests instantly and blocks access to malicious domains before a connection is established.
