Discover key strategies for effective threat intelligence management. Enhance your security posture
In cybersecurity, speed matters. But so does clarity. When your organization is facing hundreds or thousands of known vulnerabilities, not every one deserves immediate attention. The real challenge is knowing which ones do and acting fast. That’s where the integration of threat correlation and extended detection and response (XDR) comes in.
Vulnerability remediation isn’t just about patching; it’s about remediation with context. By linking known vulnerabilities to actual threat activity in real time, organizations can transform their vulnerability remediation process from reactive to risk-informed and far more effective.
In this blog, we’ll break down how Fidelis Elevate® helps organizations speed up the remediation of vulnerabilities through ML-driven threat correlation across endpoints, networks, and cloud environments, enabling automated vulnerability remediation and better prioritization. Let’s get into it.
Most security teams don’t struggle with knowing what vulnerabilities exist. Between vulnerability scanners, asset inventories, and third-party feeds, visibility is often not the issue. The problem is volume and a lack of context.
You get a list of 1,000 vulnerabilities across 5,000 endpoints. Which ones are being exploited? Which ones pose a real business risk? And which ones can wait?
Without clear answers, organizations either freeze, doing nothing out of caution, or overcompensate by wasting time and resources patching low-priority issues.
What is needed is a shift in how we approach the vulnerability remediation process. One that prioritizes speed and relevance.
Extended Detection and Response (XDR) platforms like Fidelis Elevate® bring this shift to life by correlating vulnerabilities with real-time threat behavior. Instead of treating CVEs as isolated issues, Fidelis XDR ties them to:
This threat correlation is what makes vulnerability remediation intelligent and timely. It’s the difference between guessing what to fix first and knowing exactly what to act on.
So, what exactly is threat correlation? In simple terms, it’s the process of connecting the dots between disparate signals endpoint alerts, network anomalies, cloud behaviors, vulnerability scans, and more to form a complete picture of a potential attack.
But when deployed through XDR, threat correlation becomes predictive. It helps your SOC spot threats in progress, link them to known vulnerabilities, and prioritize those vulnerabilities for immediate remediation.
Fidelis XDR takes this further with ML-driven threat correlation combining behavioral analytics, threat intelligence, and real-time telemetry to surface the vulnerabilities that are not only present but actively being targeted.
Here’s how Fidelis Elevate® speeds up and strengthens your vulnerability remediation process:
Fidelis provides deep visibility across endpoints, networks, and cloud environments. This allows you to maintain a dynamic, up-to-date map of network security vulnerabilities as they emerge and evolve.
But more importantly, Fidelis doesn’t treat this data as static. It integrates with your existing vulnerability scanners to monitor exploit activity and determine which vulnerabilities are being weaponized in real time.
Not every high-CVSS (Common Vulnerability Scoring System) vulnerability is high risk. Fidelis XDR applies contextual threat correlation to assess not just what’s exploitable, but what’s actually being exploited.
For example:
By layering this context, Fidelis helps you decide how to prioritize vulnerability remediation more effectively.
Once a high-priority vulnerability is identified—especially one actively tied to threat behavior—Fidelis can trigger automated vulnerability remediation workflows via integrations with patch management and ITSM platforms.
This automation ensures remediation happens immediately, without waiting on manual ticketing. Especially for cloud workloads and critical infrastructure, where every second matters.
Today’s infrastructure isn’t just on-prem. That’s why Fidelis supports the most effective vulnerability remediation for cloud environments, covering containers, APIs, misconfigurations, and exposed services.
It not only detects vulnerable assets but identifies which ones are being actively targeted, whether in AWS, Azure, or hybrid setups, and helps secure them fast.
Here’s what sets Fidelis apart when it comes to improving vulnerability remediation effectiveness:
| Challenge | Fidelis XDR Capability |
|---|---|
| Too many vulnerabilities, not enough context | ML-driven threat correlation pinpoints what’s actively exploited |
| Slow manual response cycles | Automation triggers reduce time to remediation |
| Cloud vulnerabilities go unnoticed | Full visibility into cloud-native and hybrid threats |
| Poor prioritization of patches | Context-based scoring aligned with attacker behavior |
| Limited integration with existing tools | Native integrations with vulnerability scanners, SIEM, and ITSM tools |
In short: Fidelis doesn’t just help you find vulnerabilities. It helps you fix the right ones faster.
Recently, Microsoft SharePoint was exploited in a targeted attack where threat actors took advantage of an unpatched vulnerability to gain unauthorized access to enterprise systems. The vulnerability publicly disclosed but left unremediated in many environments, was leveraged to move laterally and exfiltrate sensitive data from internal servers.
Many organizations using SharePoint had the CVE listed in their vulnerability scanner reports. But without context, it sat in a backlog. The attack wasn’t detected until unusual outbound network traffic was observed and linked to SharePoint processes, by which time damage was already done.
Outcome: What could have taken days or weeks to uncover manually is neutralized in minutes, significantly reducing exposure, impact, and MTTR.
Traditional vulnerability remediation is linear: detect, assess, patch. But that model assumes all vulnerabilities are equally dangerous, which simply isn’t true.
Threat correlation introduces a smarter layer. It bridges static risk data with dynamic threat behavior. And in a world where attackers move fast, that correlation is what helps your team move faster.
With Fidelis Elevate, this intelligence is built into every step of the response pipeline from detection to containment to remediation.
In today’s threat landscape, having visibility into vulnerabilities is no longer enough. Speed, context, and automation are the real game-changers.
Fidelis Elevate® delivers all three by combining:
The result? A smarter, faster, and more focused vulnerability remediation process that cuts down response time, reduces risk, and helps your security team stay ahead.
