What it stops

Stop Threats at the DNS Layer

Many cyber threats rely on DNS to reach malicious infrastructure, communicate with compromised devices or move data undetected. Asavie Network Security helps operators identify and block suspicious DNS activity before it becomes a bigger problem.

Malicious Domains

Block access to known malicious domains associated with phishing, malware distribution and other online threats, helping protect subscribers before connections are established.

Botnet Communications

Disrupt malware communications by blocking DNS requests to known command-and-control domains, making it harder for compromised devices to communicate with attackers.

Emerging Threats

Stay ahead of evolving cyber threats with continuously updated threat intelligence, helping identify and block newly discovered malicious domains as they emerge.

Why DNS security

Built into the Network, Protection at Scale

DNS is a critical part of mobile connectivity and a natural point to identify and disrupt cyber threats. By applying security policies at the DNS layer, operators can help protect subscribers from malicious destinations before connections are established.

Asavie Network Security integrates with the operator's DNS infrastructure to deliver centralised, intelligence-driven protection across connected devices, without requiring endpoint software or routing user traffic through additional security gateways.

Carrier-grade scalability: designed to protect millions of subscribers and connected devices
Minimal network impact: enforces security at the DNS layer without adding traffic inspection gateways
No device software required: protects supported devices regardless of operating system, with nothing to install or maintain
Always-current threat intelligence: continuously updated intelligence helps block newly identified malicious destinations
Actionable security insights: clear reporting on detected threats, blocked requests and security trends

Precision policies

The Right Protection for Every SIM

One network, millions of devices, different security needs. Asavie Network Security lets operators apply granular DNS security policies to individual SIMs, combining threat intelligence with flexible filtering rules to deliver personalised protection at scale.

01Per-SIM Security PoliciesApply tailored DNS filtering policies to individual subscribers and connected devices, based on their specific security needs.
02Flexible Filtering RulesDefine policies using domain names, IP addresses, DNS query types and other supported criteria.
03Intelligent Policy CombinationsCombine multiple filtering conditions to create precise security rules without unnecessarily restricting legitimate traffic.
04Continuously Updated ProtectionCombine dynamic threat intelligence with operator-managed allowlists and blocklists to respond to evolving threats.
05Configurable Security ActionsAllow, block or redirect DNS requests according to the policies assigned to each SIM.
06Centralised Policy ManagementManage and adjust security policies across millions of SIMs from a centralised control plane, simplifying operations at scale.

Visibility

Every Threat, Every SIM, Clear Visibility

Turn DNS security activity into actionable insights. Asavie Network Security gives operators visibility into detected threats, blocked requests and policy enforcement across their subscriber base. From network-wide security trends to individual SIM activity, understand what's happening, where threats are emerging and how protection is performing.

Data in transit is protected by removing it from the public internet
Works on any device with a SIM card, with zero gaps in visibility and security
Add or remove features and change policies at any time
Deploys in minutes, without clients and with minimal disruption

FAQ

Network Security Questions

It uses the DNS resolvers in your network to detect and stop malicious activity. Reaching a command and control server, a malware download or an exfiltration site almost always starts with a DNS lookup, so blocking that lookup stops the attack early.

No. Asavie works in the DNS control plane, so it adds no latency to network traffic.

Phishing, malware distribution and known botnet command-and-control infrastructure, by blocking malicious DNS requests. Continuously updated threat intelligence helps address newly discovered threats.

No. There is no security software to install or update on devices. Every device with a SIM card is covered, whatever its operating system.

Threat feeds are updated continuously as exploits change. You can also add your own lists and configure policies by hand for local problems.

Yes. Asavie Analytics APIs let operators and businesses integrate security insights into their existing monitoring, reporting and analytics platforms, to build custom dashboards, generate reports and support security operations.
