Redirect
DNS hijack, rogue records, resolver abuse — attackers choose your destination for you.
Secure the services every endpoint already trusts. Four coordinated layers—DNS Firewall, Threat Intelligence, Anomaly Detection, and Zero-Touch Containment—turning DNS and DHCP into active security controls for the modern enterprise.
DNS and DHCP are where modern breaches actually begin. Every attacker plays one of four hands.
DNS hijack, rogue records, resolver abuse — attackers choose your destination for you.
NXDOMAIN storms, query floods, DHCP exhaustion — availability destroyed at the protocol layer.
Spoofed leases, rogue DHCP, DHCP replay, MAC churn — attackers claim a trusted identity.
DGA, fast-flux, IP-only C2, lookalike domains — malware disappears into DNS noise.
DNS decides where traffic goes. DHCP decides how devices connect. Treated as plumbing, risk moves quietly. Integrated with IPAM as a complete DNS, DHCP, and IPAM (DDI) platform, these services become governed security controls that stop threats earlier, limit spread, and lower containment costs through policy-driven automation.
If attackers steer the resolver, they steer every device on your network. Govern resolution and you govern direction.
DHCP decides who joins and what configs they receive. Lose the lease, lose the blast radius.
Most attacks do not announce themselves. They arrive as a domain lookup, a lease request, or a pattern that looks ordinary — until it is too late.
The earliest decisions in your network do not show up in dashboards — they show up in dwell time, audit findings, and the questions executives ask after an incident. Scroll the chapters. The visual moves with you.
The longer a hostile lookup or rogue lease lives unnoticed, the more identity, lateral movement, and exfiltration paths it opens. Time, not signatures, decides the size of an incident.

Rogue DHCP and misconfigured DNS silently redirect users and devices — turning trust into compromise. One unseen DNS path becomes six executive problems: regulatory, legal, operational, brand, financial, and SOC capacity. DNS and DHCP failures don’t stay in the network team — they surface in audits, board reports, and customer trust within days.
When the three core network services run on separate platforms, each one sees only a slice of the incident. Queries, leases, and address assignments never reconcile in real time, so enterprises chase the same threat across three consoles and three data models — and contain it in none of them.
No proof, no accountability. Fragmented logs make it impossible to answer “who changed what, when, and where” — hurting incident response, compliance evidence, and post-incident review.
When protection depends on location or VPN, roaming users get inconsistent security. Each connection follows a different path, no enforcement plane sits in the middle, and gaps get patched by hand — one ticket, one exception, one cost at a time.
“Security should not depend on where users connect.”
Treating DNS and DHCP as background plumbing pushes prevention out of reach and pushes accountability up the org chart. The strategic stake isn't a tool decision — it's whether the doorway to your business is governed at all.
Watch the shift unfold — how complexity spreads, visibility fragments, and control weakens, and how DDI Central restores clarity across DNS and DHCP.
Cloud, branches, roaming users, IoT — every endpoint adds a new place where DNS and DHCP get asked the wrong question.
Point tools see slices. No one sees the path from query to lease to device to user — the chain that actually defines an incident.
Without a central security brain at the DDI layer, decisions get delayed, escalations get manual, and attackers live in the gaps.
Treat DNS and DHCP as security controls — not background services — and prevention, detection, and containment all move closer to the threat.
One control plane. Four enforcement layers. A continuous security posture that acts where access decisions are made.
Walk the strategy the way a security leader would: one continuous posture, four coordinated enforcement layers, each closing a specific gap — so control begins earlier, visibility stays whole, and response moves at the speed of the network.
Instant filtering of known-bad domains and policy-based DNS control via RPZ.
Inside Layer 1 →Live, curated domain and IP intelligence with confidence-scored enforcement.
Inside Layer 2 →ML-driven screening of DNS and DHCP behavior to catch emerging threats.
Inside Layer 3 →Automated quarantine across DNS, DHCP, or both — based on risk severity.
Inside Layer 4 →Open any layer for the underlying capability detail.
DDI Central's DNS Firewall intercepts queries before they reach dangerous destinations. With RPZ-driven policy enforcement, security teams block, redirect, or sinkhole known-bad destinations and keep users away from malicious domains before access is established.
"Known bad should never become active risk."
Malicious query intercepted · Resolution denied · Exposure prevented
Curated, real-time threat feeds enrich every resolution decision. STIX/TAXII compatibility means your resolver gets the same intelligence your SOC already trusts — and acts on it automatically.
"If the world knows the threat, your resolver should know it too."
Live feeds enter · Confidence scores rise · High-risk domains are enforced automatically
Machine learning establishes a baseline of normal DNS and DHCP behavior, then surfaces deviations the moment they appear — DGA traffic, beaconing, lease anomalies, MAC churn. Early signal. Less noise. Smaller blast radius.
"When the indicator does not exist yet, behavior still leaves a trail. Patterns emerge before incidents do."
Block the destination. Block the resolver. Deny network admission. DDI Central quarantines suspicious clients across DNS, DHCP, or both — automatically, based on configurable severity thresholds — while keeping security teams in control.
"Attackers do not wait. Your containment should not either."
If you can't bind query → lease → device → user, you can't contain. DDI Central holds the binding chain.
One binding chain. Every action attributable. Every decision auditable.
"Who had this IP last week?"
Historical lease attribution on demand — instantly surface which device or user owned any address at any point in time.
"Which domains did this IP resolve?"
DNS resolution timeline for every address — full query history enriched with identity context.
"Where else did this hostname appear?"
Lateral movement tracing across scopes — follow a threat actor's footprint across your entire network.
Incidents don't fail at detection. They fail at decisions. A defense strategy becomes valuable only when it helps teams make the right security decisions consistently. In DDI Central, the defense-in-depth stack brings together DNS Firewall, Threat Intelligence, Anomaly Detection, and Zero-Touch Containment to operationalize six key security decisions at the DNS and DHCP layer.
Can security enforcement be governed centrally?
The stack gives teams a centrally governed way to define and apply DNS and DHCP security controls across environments. Instead of fragmented enforcement, protection is coordinated through one operational layer.
Do we have the right DNS and DHCP signals in real time?
The stack works on live DNS and DHCP activity as its decision substrate. Query behavior, lease activity, policy hits, anomaly indicators, and known threat signals become the operational data behind every action.
Can we actively block, redirect, and regulate malicious activity?
This is where enforcement becomes real. DNS Firewall applies controls such as DNS sinkholing, RPZ, and RRL, while Threat Intelligence continuously strengthens enforcement with known malicious domain intelligence.
Can we surface suspicious behavior early enough to act?
The stack improves visibility by combining Threat Intelligence for known bad infrastructure and Anomaly Detection for suspicious DNS and DHCP behavior that static policies alone may miss.
Can we contain threats quickly without waiting for manual response?
With Zero-Touch Containment, the stack moves from detection to action. Suspicious or risky activity can trigger containment workflows automatically, helping reduce attacker dwell time and limiting exposure earlier.
Can we prove what happened and how the stack responded?
An effective defense layer must also be verifiable. Policy hits, anomaly detections, threat-intel-driven blocks, and containment actions together create an evidence trail that supports investigation, validation, and post-incident review.
Users roam. Perimeters disappear. DDI Central enforces the same defense-in-depth posture across every environment.
Define DNS and DHCP security policy once, then govern it from a single control plane across data center, branch, roaming users, and cloud — no fragmented consoles, no drift.
The path from signal to action becomes shorter, cleaner, and more decisive.
Known threats blocked earlier. Suspicious behavior surfaced faster. Risky clients isolated before lateral movement grows.
Move from alerting to automated action at the DNS and DHCP layers — without waiting for human bottlenecks.
Layered prevention, intelligence, behavior, and containment — a unified DDI security posture by design.
Audit-friendly visibility into what was blocked, when, and why — with a forensic trail attached to every decision.
One control plane across HQ, branches, cloud, roaming users, and IoT — policy that travels with the user.
A layered approach to securing DNS, DHCP, and IP address management — so known threats can be blocked, unknown behavior can be detected, and compromised clients can be contained automatically.
Through DNS firewall-based domain blocking, RPZ-driven policy control, threat intelligence feed ingestion, anomaly detection, and DNS-based quarantine workflows — coordinated in one control plane.
Yes. Its anomaly detection engine uses machine learning to identify suspicious DNS traffic and DHCP client behavior before such activity is formally recognized by threat feeds or authorities.
Yes. DDI Central can quarantine suspicious clients and domains automatically when severity thresholds are exceeded, and admins can configure containment through DNS, DHCP, or both.
Yes. The platform supports ManageEngine CloudDNS and other supported vendors, plus standards-compliant STIX/TAXII sources.
DDI-led defense in depth gives security teams earlier control over the services every endpoint already trusts. Harder to disrupt. Harder to misuse. Faster to defend.
