DNS Security

DNS is a critical yet often overlooked target for cyberattacks. Leader Technology provides a multi-layered DNS Security framework that protects your infrastructure, validates your traffic, and automates your defense.

Infrastructure & Protocol Protection

  • Access Integrity: We enforce strict controls over DNS record updates to prevent “hijacking” and ensure users are never rerouted to malicious sites.
  • Hardened Protocol: By implementing DNSSEC for data integrity and DNS over HTTPS (DoH) for privacy, we ensure your DNS communication is both authentic and encrypted.
  • DDoS Mitigation: Features like Response Rate Limiting prevent your servers from being exploited in large-scale volumetric attacks.
 

Intelligent Detection & Analytics

Proactive Blocking

Using Response Policy Zones (RPZ) and real-time Threat Intelligence, we automatically block access to known malicious domains.

Tunneling Defense

Our advanced analytics identify sophisticated threats like DNS Tunneling, stopping data exfiltration that standard filters miss.

Actionable Insights

We turn complex system logs into clear reports, allowing you to spot emerging trends and tune your security posture instantly.

Automated Response

  • Instant Remediation: DNS is often the first indicator of a breach. Our solution acts as a trigger to automatically isolate infected devices the moment they attempt to contact a malicious server.
  • Ecosystem Harmony: We integrate with your existing security stack to ensure your firewalls and endpoints react in unison to DNS-detected threats.
Leader Technology turns your DNS from a potential vulnerability into a proactive security asset, providing the visibility and speed needed to protect the modern enterprise.
