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.
KSPL DNS Security continuously monitors DNS activity and applies configurable policies to identify and block suspicious communication in real time.
Prevents users and systems from resolving domains flagged as malicious, suspicious, or prohibited by policy.
Flags unusual query patterns that may indicate attackers hiding C2 traffic or exfiltrating data inside DNS packets.
Analyzes query frequency, entropy, and lexical structure to surface deviations from normal network behavior.
Blocks access to known phishing and malware domains at the resolution layer — before a connection is ever established.
Identifies domain communication patterns associated with malware attempting to reach external C2 infrastructure.
Uses lexical and behavioral analysis to catch algorithmically generated domains commonly used in malware campaigns.
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:
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.
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.
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.
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:
Manage DNS security policy, logging, and operations from a single unified platform.
Machine learning-based anomaly analysis catches novel DNS threats signature tools miss.
Block or redirect malicious domains directly at the resolver, with no endpoint agents required.
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. |

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:
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.
