How Protective DNS Is Reshaping Workplace Security and Ethics
The Domain Name System (DNS) is the internet's directory service: an invisible layer that makes nearly every online interaction possible. It's typically viewed as a defensive control; organizations can use protective DNS to block malicious domains and phishing attacks. These are universally bad occurrences, meaning that they are equally as bad for private consumers as they are for your company's CEO.
But protective DNS isn't just about stopping cyber threats; it's also about shaping safer, more intentional digital environments across businesses, governments, homes and other organizations. It's about supporting content governance and promoting ethical internet use.
We're seeing organizations increasingly take an interest in this, not just to block universally bad entities, but also to protect specific communities. For instance, my research team recently found that in the past year, more companies have been blocking employees from accessing adult content and illegal torrenting sites.
Every device, user and application depends on DNS. If you're using the internet, you are using DNS-full stop. Firewalls are optional. VPNs are optional. DNS isn't. Because of its universality, DNS has become a natural enforcement layer for network policies, whether for security, compliance, productivity or digital well-being. Unlike complex firewalls or endpoint tools, DNS filtering is lightweight, scalable and intuitive, requiring little expertise to implement.
Furthering Safety And Compliance
Cybersecurity threats aren't the only kind out there in the wild internet world.
Child sexual abuse material (CSAM) is a significant example of the kinds of harmful material proliferating on the internet, and it's a growing problem. The most recent global assessment from the WeProtect Global Alliance (a nonprofit founded to create a cohesive, comprehensive response to the widespread issue of online child sexual abuse and exploitation) found that the volume of child sexual abuse material reports increased by 87% from 2019 to 2023.
Generative AI is making the problem worse, driving the growth of CSAM.
A 2024 report from the Internet Watch Foundation found over 3,500 new AI-generated criminal child sexual images were uploaded to one dark web forum in the eight months since the organization's prior analysis.
As AI models increase in sophistication, unregulated AI image generation will make it harder to identify pathways of direct harm. And though age restriction and photo identification laws for some websites, including adult forums and sites, are intended to help protect minors, the irony is that these measures could actually make it more challenging to find, track and remove victims' content. How? Stringent rules most likely steer users away from the more open forums and toward servers that are more private and shared.
Adult content, self-harm content and terrorism-related sites are a few more examples of the types of potential threats and/or problematic content on the internet that some organizations may want to block access to.
Creating A Better Workplace
Enterprises can also leverage DNS filtering to reduce distractions (e.g., gambling, adult or dating sites) and enforce human resources or compliance standards.
Organizations are increasingly making use of this; for instance, recent analysis by DNSFilter of what companies are looking to block (outside of security threats) found that adult content is present in over 84% of those policies.
Other common elements in such policies include things like illegal torrenting/peer-to-peer sharing sites, which we've seen in 81% of policies. Terrorism and hate are another common category, blocked by almost 66% of the companies we work with. Gambling is another frequently blocked category. We've also seen a crackdown on access to self-harm content, which has shown up in 234% more policies in 2025 than the year prior.
At first glance, it would seem that these sites should always be blocked for everyone, but researchers and experts might need access to them to perform their job roles. Organizations can make informed decisions about where filtering and blocking make sense, especially when it comes to protecting certain communities from harm. Ultimately, this can lead to a more equitable, more productive workplace that puts safety and compliance at the center without intrusive monitoring.
The Expanding Role Of DNS
Protective DNS is usually framed as a defense against cyberattacks, but its applications extend far beyond security. From filtering CSAM and gambling sites to reducing workplace distractions, it can serve as both a safeguard and a visibility tool. As the digital landscape becomes increasingly complex-with the rise of generative AI, IoT and misinformation-DNS will evolve into the first line of digital policy enforcement, combining threat protection with ethical governance.
HTTP was replaced by HTTPS, which became non-negotiable for web safety. In the same way, protective DNS will and should replace standard DNS. In fact, CISA has already done this across the federal government. Filtering and blocking will become a baseline expectation for digital responsibility.
Companies, governments and even families can leverage DNS to enforce policies, protect users and shape digital environments responsibly. Whether protecting citizens, employees or families, DNS is redefining what it means to create a safer, smarter internet.
