Stop threats at the network level
Block malicious traffic before it reaches your devices. Isolate compromised endpoints instantly—no manual intervention required.
The challenge
Traditional security leaves IoT networks wide open
Most networks operate on a “default allow” posture—permitting traffic unless it’s explicitly blocked. For IoT deployments at scale, this creates a massive, unnecessary attack surface where devices can communicate with any destination until a threat is identified.
You’re managing thousands—maybe millions—of connected devices across cellular networks. Each one is a potential entry point. And you’re likely facing:
Unpatchable vulnerabilities you can't fix instantly across every device
Zero-day threats that bypass signature-based defenses
Manual investigation and remediation that's tedious and inconsistent
Security teams burning out from repetitive, high-volume response tasks
The result? By the time you identify a threat and manually intervene, it’s already spreading. Attackers exploit the window between detection and response, moving laterally and establishing persistence across your IoT environment.
Our solution
Automated threat protection at network speed
Aeris IoT Watchtower Protection detects and blocks IoT threats automatically before they can spread. Instead of waiting for manual response, you get real-time malware protection, Zero Trust enforcement and automated containment that works at the speed of attacks.
Aeris IoT Watchtower Protection integrates threat intelligence directly into your cellular network, automatically blocking traffic to malicious destinations and isolating compromised devices before lateral movement occurs.
With Aeris IoT Watchtower Protection, you can:
Detect and block malicious traffic using real-time threat intelligence
Enforce Zero Trust policies that deny all unauthorized communication
Contain compromised devices instantly to prevent lateral movement
Integrate with your SIEM for coordinated security operations
Prove enforcement with complete audit trails of blocked and allowed traffic
Aeris IoT Watchtower Protection moves you from reactive response to proactive automated defense, stopping attacks at IoT scale.
Our approach
Network-level security purpose-built for cellular IoT
Traditional network security creates a dangerous delay between threat detection and response. At IoT scale, manual intervention simply can't keep pace. Our approach eliminates that gap entirely.
Integrate threat intelligence directly into the cellular network
Aeris IoT Watchtower Protection embeds security controls at the network level—where your IoT devices actually communicate. Threat intelligence feeds are applied automatically across your entire fleet, blocking malicious destinations in real time without touching individual devices.
Automate the entire threat response cycle
Detection, blocking, containment and verification happen automatically at network speed. No tickets, no manual firewall updates, no waiting for security analysts to investigate and respond. Threats are neutralized the moment they're identified.
Enforce Zero Trust by default
We flip the security model from "allow everything unless blocked" to "block everything unless approved." Only explicitly permitted communication is allowed, eliminating entire classes of threats before they can exploit your devices.
Defend at IoT scale without analyst burnout
Protect millions of devices without scaling your security team. Automation handles response while analysts focus on strategy.
Prove every action with audit trails
Every blocked threat, every allowed connection, every policy action is recorded—giving you complete visibility for compliance and forensics.
Features
Advanced protection that stops threats automatically
Move beyond basic access controls to proactive threat defense. Aeris IoT Watchtower Protection delivers automated malware blocking, SIEM integration and granular device group policies that protect your IoT environment at scale.
| Feature functionality | Operational value | |
|---|---|---|
| Allow and Block enables you to permit/deny access from IoT devices over cellular data. | → | Restrict access to destination endpoints specified as Fully Qualified Domain Names (FQDN), IP subnets, ports and protocols. |
| Rate Limiting configures data consumption thresholds to activate predefined cellular data access policies. | → | Activate specific security policies or cellular data throughput rate by International Mobile Subscriber Identity (IMSI). |
| Blocked Traffic Report details blocked cellular data access due to an active enforcement rule. | → | Confirm that enforcement rules are working and identify which devices attempted unauthorized access, so teams can quickly validate containment and investigate potential issues. |
| Application Usage Report provides a view of allowed cellular data access. | → | Understand which applications are consuming cellular data across your IoT footprint to control usage, reduce unexpected costs and validate that devices are behaving as intended. |
| Policy Application enables you to apply one global enforcement policy for any device using a certain Access Point Name (APN). | → | Apply consistent network controls across groups of devices at scale, simplifying policy management and reducing operational effort as IoT deployments grow. |
| SIEM Integration connects Aeris IoT Watchtower with an enterprise Security Information and Event Management (SIEM) system. | → | Stream security events to a security operations center. Integrate Watchtower into security operations and incident detection and response processes for centralized visibility. |
| Malware Protection provides threat-intelligence classification of devices’ traffic updated daily to protect against latest threats. | → | Real-time monitoring prevents devices from connecting to malicious endpoints. Four levels of malware protection can be configured, from None to Aggressive, automatically blocking traffic toward malicious endpoints. |
| Policy Application: Device Groups groups different devices (SIMs) using a specific APN into distinct Device Groups. | → | Configure a different enforcement policy for each Device Group. Create dedicated enforcement policies to suit different devices with different access needs based on use case. |
| API Access provides programmatic access to Watchtower REST API to perform Read or Write operations. | → | Enable automated workflows and integration with existing security and operations platforms.
