Secure your identity

Your corporate identity is controlled by DNS. Under normal operation, DNS is completely invisible to your customers. But, when it fails, your customers can no longer find your website, send you email or buy your products online. Monitoring DNS is the only way to ensure your business's online identity remains secure.

MxToolBox DNS Monitoring alerts you to DNS changes before outages take hold and affect your customers.

And, DNS is vulnerable to attack!

MxToolBox DNS Monitoring alerts you to potential DNS-based attacks that could compromise your customers' data and your company's reputation.

Protect against Man-in-the-Middle Attacks

Spoofing, or Man-in-the-Middle attacks, involve a compromised DNS server that routes your customers through a fake proxy site to record their information. MxToolbox DNS monitoring can detect when a proxy is on the Internet and give you warning that your DNS records are being compromised.



Protect against DNS Hijacks

Hijacking attacks change your DNS registration and point it to a website that replicates your look and feel to fool your customers into passing over their vital information. MxToolbox DNS Monitoring will detect a change to your DNS record and immediately alert you, giving you early warning that an attack is underway.


Protect Server Uptime

It's easy to make a mistake with DNS that affects your customers and your uptime. With MxToolBox DNS Monitoring, we alert you when you've changed a monitored DNS record. You get peace of mind knowing knowing that you will be alerted when DNS changes occur, regardless of the source.
