Rapid Response¶
NodeZero's Rapid Response feature helps you stay on top of critical, late-breaking N-day vulnerabilities and outrun attackers. The Horizon3.ai Attack Team proactively assesses your environment's assets for susceptibility to new vulnerabilities. Rapid Response then alerts you (via email and in the NodeZero Portal) if any of your assets are found to be exploitable, and provides targeted tests to quickly check assets' exploitability and remediation.
Not available on all license types
Rapid Response is available with certain license categories, or as an add‑on feature. Contact your Horizon3.ai Account, Customer Success, or Support representative to add Rapid Response to NodeZero.
What Rapid Response Tells You¶
To help defenders identify and respond to real threats as soon as possible after their discovery, Rapid Response distills vulnerability noise into actionable signal. Rapid Response offers personalized responses to these questions:
- Which emerging vulnerabilities pose real exploitability risk?
- Am I exposed to that risk, and where?
- What do I need to do next, and how urgent is it?
- Did my fix work, and can I prove it?
These answers can dramatically cut down attackers' window of exploitation when a new vulnerability comes to light.
How Rapid Response Works¶
As a personalized, context-aware risk engine, Rapid Response maps internal and external exposures based on your historical penetration-test data. It sends alerts to subscribed members of your organization, and categorizes your assets with precise statuses (Exploitable, Potentially Relevant, Mitigated, Not Exploitable, Regressed), which update as you act. Embedded ticketing workflows turn each Rapid Response into a prioritized to-do list. Proof artifacts close the loop. Alerts resume if a vulnerability ever regresses.
The feature is backed by Horizon3.ai's team of attack engineers, who continually monitor and research new vulnerabilities. Using our knowledge of exploitation patterns – prioritizing internet-facing and easily leveraged vulnerabilities – we sift out risks with proven real-world exploitability and severe business impact. Then we develop production-safe tests to validate these risks.
Rapid Response routinely ships tests and alerts ahead of the CISA KEV catalog – the U.S. Cybersecurity and Infrastructure Security Agency’s industry-standard reference list of Known Exploited Vulnerabilities. This helps defenders focus their capacity on the most exploitable threats, including threats not yet publicly disclosed.
Rapid Response Components¶
Specific capabilities include:
- Asset-level vulnerability mapping, with scannable summaries linking to rich details.
- Clear indications of assets not at risk.
- Specific guidance about which tests and fixes to prioritize.
- Targeted tests to efficiently verify your remediations.
- Dashboards to track, validate, and demonstrate your progress.
- For opted-in environments, proactive asset checks the moment we get a working exploit – notifying you instantly if we confirm you have assets exposed.
