Understanding the Limitations of DNS Filtering

DNS filtering services like Adguard DNS have their limitations, and it is essential to be aware of them:

  1. Dynamic and Evolving Threat Landscape: The online threat landscape is constantly evolving, with new malicious websites and tactics emerging regularly. While Adguard DNS strives to stay up-to-date with the latest threats, it may not always be able to block new or zero-day threats immediately.
  2. Bypassing DNS Filtering: While DNS filtering can effectively block access to malicious domains, determined attackers may find ways to bypass these filters by using alternative DNS servers or employing encryption techniques.
  3. False Positives and Negatives: DNS filtering relies on maintaining a comprehensive database of known malicious domains. However, this can lead to false positives, where legitimate websites are wrongly blocked, or false negatives, where malicious sites are not detected. Adguard DNS aims to minimize such occurrences but cannot guarantee a completely error-free filtering process.

Despite these limitations, DNS filtering services like Adguard DNS play a crucial role in enhancing online security and protecting users from a wide range of threats. By understanding the risks and taking additional security measures, users can further fortify their online defences.
