When a critical vulnerability is disclosed, the clock starts immediately. Based on current median Time-to-Exploitation (TTE) data, organizations have days – sometimes hours – before exploitation begins in the wild.
What happens inside watchTowr in that window is not a manual triage process. It is a coordinated, continuous capability built specifically to move faster than the threat.
Two Teams, One Platform
Rapid Reaction at watchTowr is driven by two capabilities working in parallel – and both feed directly into the platform’s automated engines.
- watchTowr Intel is the Proactive Threat Intelligence team responsible for monitoring attacker behavior continuously: tracking what threat actors are doing, identifying patterns in how they operate, and anticipating which newly disclosed vulnerabilities are likely to attract immediate attacker attention. When a disclosure lands, watchTowr Intel does not wait for exploitation to be confirmed in the wild. It assesses likelihood based on what attackers are actually doing right now.
- watchTowr Labs is the vulnerability and exploit development team responsible for doing what most security vendors do not: independently reproducing and validating vulnerabilities from first principles. When a CVE is disclosed, Labs works to understand exactly how the vulnerability works, whether it is exploitable in real-world conditions, and what exploitation actually looks like in practice.
That intelligence does not sit in a report. It is applied directly to the watchTowr Platform, combined with knowledge of each client’s assets, fed into the Automated Red Teaming framework, and used to validate exploitability across the client base automatically. Organizations receive validated, technically grounded answers about their actual exposure – not a repackaged vendor advisory, and not a finding that requires further investigation before anyone can act.
What That Looks Like In Practice
When Ivanti EPMM Pre-Auth RCE vulnerabilities CVE-2026-1281 and CVE-2026-1340 were disclosed and added to CISA KEV, watchTowr’s response unfolded in hours, not days:
- 0 hours – Vulnerabilities disclosed. watchTowr Intel immediately flags high likelihood of attacker attention based on the vulnerability class, affected technology, and current attacker behavior patterns.
- +0.5 hours – Rapid Reaction identifies exposure across the client base. Organizations know within 30 minutes whether they are affected, which systems are exposed, and what their risk looks like – before exploitation is observed in the wild.
- +2 hours – watchTowr’s Attacker Eye sensors begin capturing exploitation artifacts – shells, backdoors, and other indicators of active exploitation – providing real-time confirmation of in-the-wild activity.
- +16 hours – Active Defense capabilities are released to the client base, enabling network-level mitigation for organizations that are exposed and for whom a patch is not yet available or deployable.
From disclosure to validated exposure across the client base in under 30 minutes. From disclosure to active mitigation capability in under 16 hours.
Why The Sequence Matters
Each step in that sequence is deliberate. Rapid Reaction answers the question that matters first: are we affected, right now? It does not wait for CISA KEV confirmation, vendor guidance, or industry-wide alerting – all of which, under today’s timelines, arrive too late to change outcomes.
Active Defense picks up where Rapid Reaction leaves off. When exploitation is active and a patch does not yet exist or cannot be deployed immediately, the window between knowing you’re exposed and being able to do something about it is exactly where damage occurs. Active Defense closes that window by delivering automated, intelligence-driven protection the moment a validated exposure is identified – giving organizations coverage when they need it most.
The goal is not to react after exploitation is confirmed. It is to move faster than exploitation begins.
Preemptive Exposure Management in Practice
The Ivanti example is not an exception. It is how watchTowr operates across every high-severity disclosure – a repeatable, continuous process built around the reality that defenders no longer have weeks to work through the questions that sit between a disclosure and a decision.
watchTowr’s Preemptive Exposure Management solution brings Rapid Reaction and Active Defense together as part of a single, integrated capability. From the moment a vulnerability is disclosed, organizations have the intelligence to know if they are affected, the validation to act with precision, and the protection to stay covered while remediation catches up.
The goal is not better reporting. It is a faster, more certain reaction – before the window closes.
