MalBlock FAQs
Find answers to some of the most common questions about MalBlock DNS Security.
What are the benefits of MalBlock from Cox Business?
MalBlock just works, with very little or no configuration or software downloads. It covers every device connected to your network and protects against a wide range of threats, like phishing campaigns that can begin and end in a few hours.
What business problems does MalBlock solve?
Most businesses lack security expertise, yet they have the same risks as large companies. MalBlock can help address these issues with a service that’s both economical and nearly effortless.
How does MalBlock solve these problems?
MalBlock is a cloud-based solution that lowers the need for ongoing oversight. It automatically covers every device that connects to a company’s network.
What is unique about MalBlock?
MalBlock is a browser-based UI that provides every business with a live dashboard, which shows threat activity and other details. It’s also easy to personalize the service for your business. You can set up customized filters that block adult content, gambling websites, social media websites, or other content you don’t want on your network. Pricing is per connection/site, so it’s simple, economical, and predictable.
I have a firewall and/or antivirus software on my computer. Do I need MalBlock?
Absolutely. Simply having a firewall and antivirus software may not be enough protection against increasingly sophisticated cyber-attacks. A multi-layered security approach offers additional protection working across different protocols and applications. MalBlock is updated every 10 minutes with the latest threat intelligence and automatically blocks a wide range of known security threats to strengthen your overall security protection.
Isn’t my internet service secure? Should I be worried about my internet service?
Your Cox Business Internet service protects you from attacks from outside the network, like spam and unsolicited content. MalBlock protects your devices from actions taken inside the network, like blocking employee computers from accessing malicious websites.
What is DNS? And why is it important?
Think of DNS as a phonebook. The DNS (Domain Name System) connects an IP address to a website address (URL). It is what makes the internet simple to use, but at the same time, it is one of the most vulnerable parts of your network, making it a frequent target for hackers.
