Why you need protection against DNS attacks

In today’s connected world it’s vital to protect yourself against online criminals who use man-in-the-middle attacks to redirect you to fake or malicious websites and disrupt web-connected services like your browser or email.

You may still be wondering...

DNS is an important Internet protocol that makes it possible for your device to find websites and online services. However, it is vulnerable to attacks that can trick users into thinking a fake website is legitimate.

AvastDNS can protect you against common DNS-based attacks, including phishing, man-in-the-middle attacks, and domain redirections. These attacks commonly attempt to capture the login information for your accounts at financial institutions so that hackers can steal your money. AvastDNS can flag these attempts and alert you so that you can avoid these attacks.

We have no way to track you down, we don't know what you are doing, what websites you visit — it’s none of our business.

AvastDNS runs on a cluster of servers so that Avast DNS can stay up and running even if a single server goes down. We use the other servers to restore a malfunctioning server before it has a chance to impact service.

AvastDNS follows all regulatory requirements for Service Level Agreements (SLA). This includes guaranteeing 99.99% uptime to protect against common DNS-based attacks.

AvastDNS’s SLA promises that we will protect your web browsers against attacks like phishing attempts, man-in-the-middle attacks, DNS cache spoofing, and domain misdirections that capture your critical login information.

AvastDNS supports Google Chrome and Firefox browsers.
