Advantal DNS: Secure, Resilient and Intelligent DNS for Mission-Critical Networks
How Advantal DNS combines resilient architecture, built-in security and machine-learning analytics to turn DNS into an active control layer for large enterprises.
Selected deployments across telecom and banking environments:
BSNL (Telecom) | Bank of Maharashtra (Banking) | Maharashtra Gramin Bank (Banking)
The Challenge
Every login, payment and application call starts with a DNS query. When DNS slows down or gets compromised, the business feels it immediately.
For telecom operators and banks, the pressure on DNS comes from four directions:
- Resilience: Services must stay reachable across distributed data centers, with no single point of failure.
- Security: Malicious domains, spoofing, cache poisoning and unauthorized DNS changes are real and constant threats.
- Visibility: Traditional monitoring says little about unusual query behavior, high-volume clients or suspicious domains.
- Intelligent detection: Static rules and fixed thresholds miss behavior nobody has seen before.
The need was clear: evolve DNS from a background network service into a secure, resilient, centrally controlled and intelligence-driven infrastructure layer.
The Solution: Advantal DNS
Advantal DNS is an enterprise DNS platform that brings resilient architecture, security controls, central management and ML-driven analytics into one system. It is built on four pillars.
1. Resilient DNS Architecture
- Authoritative and recursive DNS
- Redundant nodes across multiple data centers
- High availability with automated failover
2. DNS Security
- DNSSEC to validate the authenticity of DNS responses
- RPZ (Response Policy Zones) for threat-domain blocking
- TSIG and secure zone transfers, with ACL-based access controls
- DNS64 where required, plus full DNS activity logging
3. Centralized Operations
- Zone and record management from a single console
- Role-based access and central administration
- Monitoring, alerts and reporting
- API, SIEM and NMS integration
4. ML-Powered DNS Analytics
- Behavioral analysis of DNS queries
- Machine-learning-based anomaly detection that flags unusual clients and domains
- Query volume and QPS analytics, with historical detection analysis
- Threat and anomaly scoring
- Automated or operator-approved RPZ response
- Investigation dashboards for security and infrastructure teams
How We Deliver
Every Advantal DNS deployment follows a controlled, repeatable path.
Assess → Design → Deploy → Migrate → Validate → Go-Live → Optimize
- Assess and Design: Review the existing environment, design the DNS architecture and plan capacity.
- Deploy and Migrate: Harden security, migrate zones and records, implement DNSSEC and integrate with enterprise systems.
- Validate: Test performance, failover and security, then complete user acceptance testing.
- Go-Live and Optimize: Production cutover, knowledge transfer and post-production support.
Operational Outcomes
Advantal DNS is designed to deliver:
- Availability: Redundant architectures designed to reduce single-node dependency.
- Scalability: A platform ready for enterprise query volumes and future growth in users, applications and devices.
- Security: DNSSEC, RPZ, secure transfers and access controls enforced through central policy.
- Visibility: One view of DNS traffic, QPS, high-volume clients, suspicious domains and historical anomalies.
- Faster response: Analytics connected to RPZ controls, so suspicious activity can be investigated and blocked sooner.
What this means for the business:
- Greater continuity for business-critical applications and digital services
- DNS working as an active security control, with telemetry that teams can act on
- Simpler operations across distributed infrastructure
- An architecture built to grow with the organization
