6 Best DNS Website Filtering

Without a doubt, the biggest worry in the digital world is cybersecurity.

You need to strengthen your company’s online security if you have a team working for it. Using a DNS filtering solution is one method for achieving this.

However, how and why?

You may have heard of the significant cyberattacks that cost businesses a great deal of money and reputation.

These are real-life incidents that can happen to anyone, any kind of business, and any location in the world because cybercriminals are out there. Any size business can become the target of hackers who like spreading malware, ransomware, phishing scams, and other threats.

Therefore, it is imperative that you implement rigorous cybersecurity measures to safeguard your team members and employees against similar incidents. Additionally, a DNS-based web gateway or DNS filtering can be a great solution.

It can track user behavior across your network and safeguard your digital assets from malicious websites and activities. And that’s exactly what this article aims to achieve.

What is DNS filtering?

Let’s first discuss the idea of the Domain Name System (DNS) before getting into DNS filtering.

DNS functions as a phone book online. You can quickly access a website by typing in its domain name when you are on it. However, a procedure is in place in the background to ensure that your access is seamless.

You are essentially requesting the IP address of that specific website—for instance, asphostportal.com—by entering its domain name. You can then access the website by using the associated DNS server to convert it to an IP address.

Now, DNS filtering is the process of using DNS to block websites that are malicious, inappropriate, or harmful. It keeps your network safe from cyberattacks and gives you greater control over your staff members’ internet access, which boosts output.

How is DNS filtering implemented?

Your network’s incoming and outgoing web traffic is analyzed if DNS filtering is activated. Only safe traffic is therefore permitted to enter or exit your network.

By that, what do I mean?

The enabled DNS filtering solution will filter traffic between the IP address and the requested page when you enter the domain of the website. Subsequently, the filtering process classifies websites into categories, including news, social media, inappropriate, illicit, malicious, phishing, and so forth.

In this manner, the DNS filter examines all incoming and outgoing traffic, allowing only safe traffic through and blocking any that appears suspicious or dangerous based on predetermined parameters. In addition to safeguarding your internet network, it can also guard your Wi-Fi from threats.

For instance, if you have prevented your users from visiting facebook.com while they are at work, they will be unable to do so even if they try. Every time they attempt to do so during business hours, it will indicate that permission has been denied.

What Safety Benefits can DNS filtering Offer Businesses?

1. Protection from Cyberattacks

Cyberattacks including phishing, ransomware, spyware, botnets, DDoS attacks, and other threats are always a possibility for businesses. These attacks have cost businesses millions of dollars, hurting their reputation both online and offline and driving away clients.

2. Wifi Protection

Not only can DNS filtering secure a single spot, but it can also safeguard your wired networks, public Wi-Fi hotspots, and internal Wi-Fi.

Unfortunately, a lot of companies use their Wi-Fi networks without any security safeguards or filters, which makes it easier for malicious viruses and online attacks to proliferate.

Anti-malware software can lessen the risk, but it cannot completely eliminate it. They don’t shield you from threats like zero-day malware, and they stop working when they get outdated. A DNS filter is therefore a preferable option.

3. Safeguarding Your Off-site Staff

Nowadays, a lot of companies allow their workers to work from home, but in order to complete their work, they might use dubious networks. However, it might invite cyberattacks and expose your company’s information to the public. In this situation, using DNS filters can increase security.

Conclusion

I hope this has given you a better understanding of DNS filtering and its significance for your company. Therefore, don’t waste any more time and install a DNS filtering solution in your network to keep your staff safe from online threats and to monitor their web access for increased productivity.
