Your network has more to show you
An AI-native network defense platform that detects and responds to threats at network speed, before they can be exploited
GTT Defense Halo provides a holistic view of your entire enterprise network, delivering real-time visibility and protection at network speed
The network security battle has entered the AI era
Time is the new enemy. Every second between vulnerability, detection and response extends your exposure to risk and potential exploitation.
Attackers now move at machine speed
Lateral movement inside a breached network can happen in under 30 minutes and in the fastest observed cases, in seconds. Traditional security models, built around manual review and after-the-fact detection, can’t close that gap.
Proactively detecting and responding to vulnerabilities and security threats at faster than machine speed is now a foundational requirement for cybersecurity in the AI era.
closes the gap
GTT Defense Halo redefines network security for enterprises by remediating vulnerabilities before attackers find them and resolving network anomalies into confirmed threats at network speed.
GTT provides a stateful real-time model of your unique network, a visible depiction of your infrastructure, security, cloud, endpoints and operational telemetry displayed as a continuously evolving model.
This allows you to see everything, everywhere, all at once.
A Halo of Defensesurrounding your network
Halo Recon
On demand analysis of on and off network firewall and device configurations. Continuous evaluation of compatible firewall and network device configuration changes comparing against known security frameworks to uncover compliance gaps. Delivers AI-driven mitigation guidance, replacing manual reviews with always-on control.
Halo Recon
Maps all known CVEs to your monitored assets at network speed quantifying exposure risk. Prioritizes vulnerabilities with AI recommendations, shrinking time from disclosure to action.
Halo Detect
Correlates and visualizes logs and flows across firewalls, devices, VMs and servers, monitoring your assets to establish behavioral baselines. It detects anomalies at network speed and delivers risk-scored alerts before threats escalate.
Halo Response
Executes agentic runbooks to isolate and contain threats across compatible devices. Compresses time from detection to remediation with prioritized, automated responses.
Address your most critical network and security challenges
Continuous configuration analysis
Proactively identifies vulnerabilities and policy gaps across your estate providing AI driven remediation plans in real-time before attackers can discover them.
Network threat and anomaly detection
Identifies behavioral anomalies specific to your network determining in real time whether they are genuine security threats. These threats can then be remediated at network speed.
Accelerating detection-to-remediation time
Generates a stateful, real-time model of your network, visualizing every host-to-host connection and communication enabling real time threat hunting and vulnerability exposure assessment.
How GTT Defense Halo works
The visibility, context and intelligence needed to proactively protect your network
The GTT Defense Halo difference
Without GTT Defense Halo
- Days or months to identify exposure
- Findings sit in a queue, disconnected from action
- Fragmented tools, siloed data, alert fatigue
- Reactive reviews on threats detected
With GTT Defense Halo
- Seconds to surface risk-scored findings
- Prioritized alerts paired with AI-guided remediation
- Unified, correlated view across network, identity and security telemetry
- Continuous, always-on assessment
GTT Defense Halo is builtfor both network and security professionals
Time = Risk = $
Helps you reduce uncertainty by providing continuous visibility into your risk and exposure. GTT Defense Halo enables more informed risk decisions and supports audit and compliance requirement by prioritizing findings and maintaining a fully documented record of actions.
Configuration exposure, CVE correlation
Provides you with a prioritized view of exposed risks by correlating network and security telemetry, enabling your security team to focus limited resources on the findings for the greatest impact.
Nothing to install on your endpoints
Analyzes activity at the network layer through regional collectors placed near your data sources. Correlates network and security telemetry and feeds your existing security tools through open APIs. Extends visibility across previously unseen network activity without requiring changes to your core infrastructure.
