Managed DNS Filtering
Stop Dangerous Connections Before They Start
Every time someone on your network visits a website, a DNS request is made. Our managed DNS filtering service intercepts those requests and blocks connections to malicious sites, malware sources and harmful content before anything dangerous can reach your devices.
The Threat You Cannot See Coming
Many cyberattacks rely on getting a device to connect to a malicious server. DNS filtering prevents the connection from happening in the first place, cutting off a huge proportion of attack vectors before they can cause harm.
Without DNS filtering, every device on your network has unrestricted access to the internet. For businesses with multiple users and devices, the number of potential connection points is significant.
DNS filtering also helps with productivity and compliance, reducing distraction and demonstrating to clients and auditors that you have sensible controls in place.
Malicious Sites Blocked Automatically
Our DNS filtering service maintains an up-to-date database of known malicious domains, phishing sites and malware distribution points. Connections are blocked instantly.
Protection at the Network Level
Because DNS filtering operates at the network level, it protects every device that connects to your network without requiring anything to be installed on individual machines.
Customisable Content Controls
Beyond malicious content, DNS filtering allows you to block categories of websites that are not appropriate for your business environment.
A Quiet Layer of Protection That Makes a Significant Difference
DNS filtering works quietly in the background. At AOIT, we configure, manage and monitor your DNS filtering so you get the benefit without having to think about it.
We also keep your filtering policies current as the list of malicious domains changes constantly and your business evolves.
