The Cisco Cyber Threat Trends Report 2024 highlights the vital role of DNS filtering in mitigating cyber threats. DNS is central to internet connectivity but is increasingly exploited by attackers. Heimdal DNS Security offers a comprehensive solution for small businesses, integrating seamlessly with other Heimdal modules to provide layered protection.
What is DNS Filtering?
DNS filtering blocks access to harmful websites by intercepting DNS queries before they connect to malicious websites. Heimdal DNS Security enhances this approach, working alongside tools like Heimdal NGAV, delivering a cohesive defence for small businesses.
Key threats and DNS insights
The Cisco Cyber Threat Trends Report 2024 identifies the following threats that DNS filtering can mitigate:
Information Stealers
- 246 million DNS queries blocked monthly.
- These programs harvest sensitive data, such as passwords and payment details.
- Heimdal DNS Security intercepts such malicious connections, preventing data theft.
Trojans
- 175 million blocks per month.
- Trojans often serve as gateways for further infections.
- Heimdal’s layered security detects and neutralises threats across DNS and endpoints.
Ransomware
- 154 million blocks monthly.
- Ransomware uses DNS for propagation and communication.
- Heimdal DNS Security blocks malicious domains while backup solutions ensure quick recovery.
Botnets
- 31 million blocks monthly.
- Botnets rely on DNS for coordination.
- Heimdal disrupts their communication, rendering them ineffective.
Why small businesses need DNS filtering
- Cost-Effective Protection: DNS filtering can mitigate one-third of cyber incidents, saving businesses billions annually (Global Cyber Alliance).
- Early Detection: Heimdal’s threat intelligence identifies malicious activity before it impacts your systems.
- Seamless Integration: Heimdal DNS Security complements its other solutions, offering tailored, comprehensive protection.

This integration enables small businesses to strengthen security without complexity.
Recommendations for Small Businesses
To build a robust cyber security strategy, small businesses should adopt a defence-in-depth approach, as outlined in the Cisco Cyber Threat Trends Report 2024:
Implement DNS filtering
Use Heimdal DNS Security to block malicious domains and IP addresses, preventing threats before they impact your network.Patch and update systems
Regularly patch software and systems to close vulnerabilities that attackers exploit with malware like Trojans and droppers.Maintain regular backups
Perform frequent, secure backups of critical data to ensure recovery after incidents, particularly ransomware attacks.Monitor DNS activity
Analyse DNS traffic for anomalies, such as frequent queries to suspicious domains, to detect potential threats early.Deploy endpoint protection
Combine DNS filtering with advanced endpoint protection solutions, like Heimdal NGAV, to identify and block threats at multiple layers.Educate employees
Train your team to recognise phishing attempts and other social engineering tactics. Informed employees are a crucial line of defence.Segment your network
Restrict malware spread by segmenting your network, limiting its movement in the event of a breach.
The Cisco Cyber Threat Trends Report 2024 highlights the growing importance of DNS filtering as a core defence against cyberattacks. Heimdal DNS Security not only blocks threats at the DNS layer but also integrates with other Heimdal modules to deliver a comprehensive, defence-in-depth solution tailored to small businesses.
