Complete DNS Defence with DNSSight & HYAS

DNSSight links each DNS query back to the exact device, user, and process; out-of-band, with zero impact on performance.

HYAS + DNSSight in Action

Working together, HYAS Protective DNS and DNSSight stop phishing, malware, ransomware, and C2 at resolution and identify who initiated each lookup. DNS’s ephemeral design often hides ownership.

DNSSight restores it so every blocked or allowed signal becomes a decision backed by evidence without requiring agents.
Prevention is immediate, investigations move faster, and policy confidence grows.

Results at a Glance
Ownership 
for Every Alert

Risky queries link to device, user, and process. 
No dead ends.

Faster Closure

Fewer tool pivots. 
Minutes cut from triage and handoffs.

DNS via 
SIEM integration

Enriched logs replace raw DNS streams. Filtered alerts are pushed to SIEM.

First-Contact 
Detection

Never-seen domains are flagged at first resolution. Risky traffic is identified 
at the earliest touchpoint.

Continuous Control Validation

Real detections are tested against firewall, proxy, and DNS controls. Enforcement is proven with pass/fail results.

The Closed Loop

End-to-End DNS Security from 
Detection to Investigation

Do full investigations in DNSSight or, alert to SIEM, export to ITSM only for retention, routing, or reporting needs.

Enforce

HYAS applies policy at resolution, targeting the phone-home step attackers rely on.

Attribute

DNSSight records the responsible device, user, and process.

Detect early

First-Time Visit highlights never-visited domains at first touch.

Validate coverage

Access Guard exercises detections and records pass or fail across enforcement points.

Investigate

Enriched events pushed to SIEM enable rapid investigation.

What HYAS Brings

HYAS Prevention:

Stop Threats at the Source

HYAS Prevention: 
Stop Threats at the Source

  • Blocks malicious and policy violating domains at resolution, including phishing, malware, and ransomware.
  • Targets attacker communications and cuts off command and control early.
  • Detects risky patterns such as DNS tunnelling at the DNS layer.
  • Fits into existing stacks with straightforward deployment and integrations.
What HYAS Brings
our features

First-Time Visit

Your DNS traffic can tell stories—about hidden revenue, untapped efficiency, and risks neutralised before they had a name.

Access Guard

Benchmark your existing security. Evidence, not guesses.

Behind-the-VPN Insight

Maps GlobalProtect and AnyConnect IP pools back to real users. The tunnel is no longer a cloak.

our features

Early DNS Interruption

Early interruption of risky infrastructure and staged domains at resolution.

Faster Triage, Fewer Pivots

Faster triage with fewer pivots across DHCP, VPN, IdP, and EDR.

Evidence That Travels

Evidence that travels to audit and legal without rework.

Seamless Security, 
Zero Disruption

Non-disruptive adoption without agents or topology changes.

DNS Tunnelling Blocked at Resolution
SCENARIO 01

Owner and process are recorded; follow up is targeted, not stitched by hand.

Allowed But Suspicious
SCENARIO 02

First-Time Visit sends a contextual alert to SIEM; when a vital device gets an update from a new domain, the investigation starts immediately.

Read more
VPN Ambiguity
SCENARIO 03

The user behind shared VPN egress is named for each risky lookup; no more guesses or manual cross-checks.

Architecture and Operations

HYAS handles enforcement on the data path. 



DNSSight ingests DNS, DHCP, identity, VPN, and EDR context. Investigations run without changing routing. Incidents stream to SIEM when needed, and timelines export to ITSM.

FAQ

Does DNSSight block traffic?

No. DNSSight provides visibility and intelligence but does not block traffic. It integrates with your existing controls so enforcement stays where you already manage it.

Is a specific integration required?

No. DNSSight connects to the DNS data you already produce, so it works smoothly with your current setup. Any further integrations are optional and only needed if you want deeper enrichment.

Will network mapping change?

No. DNSSight operates passively and does not alter how your network is structured. Your existing mapping remains exactly as it is.

Can I use DNSSight without SIEM?

Yes. DNSSight can operate perfectly well on its own. A SIEM simply provides an optional place to bring the insights together if you want wider correlation.

How does Access Guard demonstrate HYAS value?

Access Guard validates HYAS value by safely testing HYAS blocked domains against your other security tools. It shows you which malicious domains are already blocked and where coverage gaps still exist.
