"Traditional tools are reactive: they rely on signatures, advisories, or scheduled scans, which can take hours or even days to surface issues. Rapid Reaction compresses that entire process into minutes by transforming new threat intelligence into targeted hunts that immediately test for exposure. Instead of waiting to learn about a problem after attackers are already active, security teams get validated, actionable results fast enough to act before exploitation begins.”
Designed for High-Impact Scenarios
The kinds of vulnerabilities that make headlines are exactly what Rapid Reaction is built to address. Harris pointed to two recent examples:“Rapid Reaction is built for the kind of high-impact vulnerabilities that attackers weaponize almost immediately, such as CitrixBleed2 (CVE-2025-5777) and the recent Microsoft SharePoint zero-day (CVE-2025-53770). When flaws are discovered in internet-facing systems, exploitation can start within hours, long before many organizations have even seen an advisory. By using AI within Rapid Reaction, this response time is cut from hours to minutes, and security teams can get ahead of these fast-moving scenarios and close off exposure before compromise happens.”
Applying AI Without Sacrificing Accuracy
AI can create concerns about false positives, but watchTowr’s implementation focuses on precision. Harris emphasized that accuracy remains central:“AI is being applied to give teams the one thing they need most: time to respond. However, the beauty of watchTowr’s application is that this does not sacrifice accuracy. Rapid Reaction uses automation to generate hunts from new intelligence and then actively tests for proven exploitability. Findings are tied to real, validated exposure, not hypothetical severity scores. That way, teams only see confirmed, actionable results instead of a flood of potentials and question-marks.”
Big Benefits for MSSPs
MSSPs are especially positioned to benefit. They live in the space between constant monitoring and client communication, where time and accuracy dictate value. Harris explained how Rapid Reaction strengthens that model.“Rapid Reaction allows MSSPs to move from reactive monitoring into genuine preemptive protection. As soon as a new vulnerability surfaces, they can determine in minutes whether their clients are affected and exactly where. That lets MSSPs alert clients earlier, guide remediation faster, and strengthen the value of round-the-clock defense.”
“The biggest opportunity is to shift the conversation from ‘how quickly can you respond once you’re attacked’ to ‘how do we get ahead of emerging threats?’. Rapid Reaction gives MSSPs a clear differentiator: they can show clients that emerging threats are identified and that their exposure is validated in near-real time, ensuring any identified exposure can be shut down before attackers gain a foothold. That moves them from being responders to being true partners in prevention.”
