Enterprise DNS Security That Protects Every Query

Detect, Block and Control DNS Threats Before They
Reach Your Network

Why DNS Security Matters

Detect, Block, and Control DNS Threats Before They Reach Your Network

DNS is involved in nearly every connection across an enterprise network — which also makes it one of the most exploited channels for malware communication, phishing, command-and-control (C2) activity, DNS tunneling, and data exfiltration.

KSPL DNS Security embeds enterprise-grade protection directly at the DNS layer. Built on the proven BIND9 architecture and extended with advanced threat detection, policy enforcement, and centralized visibility, the platform helps security teams stop malicious connections before they happen — not after.

How DNS Works KSPL wide

DNS Threat Protection Capabilities

KSPL DNS Security continuously monitors DNS activity and applies configurable policies to identify and block suspicious communication in real time.

Malicious Domain Blocking

Prevents users and systems from resolving domains flagged as malicious, suspicious, or prohibited by policy.

DNS Tunneling Detection

Flags unusual query patterns that may indicate attackers hiding C2 traffic or exfiltrating data inside DNS packets.

DNS Anomaly Detection

Analyzes query frequency, entropy, and lexical structure to surface deviations from normal network behavior.

Phishing & Malicious Domain Protection

Blocks access to known phishing and malware domains at the resolution layer — before a connection is ever established.

Command-and-Control (C2) Detection

Identifies domain communication patterns associated with malware attempting to reach external C2 infrastructure.

Domain Generation Algorithm (DGA) Detection

Uses lexical and behavioral analysis to catch algorithmically generated domains commonly used in malware campaigns.

AI-Assisted DNS Threat Detection

Static blocklists alone can’t keep pace with fast-evolving DNS threats. KSPL strengthens protection with machine learning-based DNS anomaly detection, analyzing each query for suspicious behavioral and domain-level signals, including:

DNS Firewall with Response Policy Zones (RPZ)

KSPL uses Response Policy Zones (RPZ) to enforce DNS security policy directly at the resolver — no endpoint agents required. Security teams can define rules to block, redirect, or otherwise control resolution for specific domains, turning the DNS layer into an efficient, centrally managed policy enforcement point.

DNSSEC for Trusted DNS Resolution

Unverified DNS responses can be manipulated through spoofing or cache poisoning. KSPL supports DNSSEC validation, cryptographically verifying the authenticity and integrity of DNS responses before they’re accepted — adding a foundational layer of trust to the resolution process.

Secure DNS with DoT and DoH

Standard DNS queries often travel unencrypted. KSPL supports DNS over TLS (DoT) and DNS over HTTPS (DoH) to protect DNS traffic from interception and tampering in transit — combining encrypted DNS with centralized policy control so privacy doesn’t come at the cost of enterprise visibility.

Complete Visibility Into Enterprise DNS Activity

You can’t secure what you can’t see. KSPL centralized dashboard gives security and operations teams a live view of DNS activity across the network, including:

  • DNS query trends — spot shifts in network activity over time
  • Top queried domains — identify the most-accessed destinations
  • Top DNS clients — trace where queries originate
  • Query types — analyze request behavior patterns
  • DNS response activity — track resolution trends and failures
  • Threat detections — investigate flagged suspicious activity
  • Server performance & QPS — monitor DNS infrastructure health

Centralized DNS Management

Manage DNS security policy, logging, and operations from a single unified platform.

Real-Time Threat Detection

Machine learning-based anomaly analysis catches novel DNS threats signature tools miss.

RPZ-Based DNS Firewall

Block or redirect malicious domains directly at the resolver, with no endpoint agents required.

DNSSEC & Encrypted DNS

Validate DNS response authenticity and protect queries in transit with DoT/DoH.

Industry Use Case
BFSI Protect DNS supporting banking apps, branch connectivity, and internal services while retaining centralized visibility and control.
Government Deploy DNS security within controlled infrastructure while keeping full authority over policies, logs, and operations.
Defence Support private, restricted network environments where infrastructure ownership and operational visibility are non-negotiable.
Telecom Secure high-volume DNS environments while maintaining visibility into requests and DNS-based threats.
Large Enterprises Centralize DNS operations and policy across distributed networks, applications, users, and infrastructure.

Deploy DNS Security Within Your Own Infrastructure

Organizations handling sensitive DNS traffic often can’t rely on third-party public DNS services for critical operations. KSPL DNS Security deploys on-premises, so you retain full control over:

  • DNS configuration
  • Security policies
  • DNS query data
  • Threat detection logic
  • Operational logs
  • Security integrations
  • Network architecture

From DNS Resolution to DNS-Layer Defence

KSPL combines DNS resolution with security intelligence, policy enforcement, and monitoring — helping enterprises stop threats at one of the earliest possible points in the network communication chain.Your DNS should do more than resolve. Let it detect. Let it protect.
