Know which vulnerabilities are actually yours

Vulnerability Management is the continuous process of identifying vulnerabilities in the software and systems you run, assessing what they mean for your environment, prioritizing them by real risk, and tracking them through to remediation. The goal is to act on the findings that matter rather than working through a list sorted by severity alone.

Severity is not risk, and a finding is not a fact

Most vulnerability programs fail in one of two directions. Either the list is too long to act on, because everything rated “High” arrives with equal weight and nothing says which of those systems matters to the business. Or the list is quietly wrong, because findings were matched to software the organization does not actually run, or missed software it does.

Both problems come from the same place. A vulnerability feed describes products in the abstract: a vendor, a product, a version range. Turning that into a statement about your environment requires knowing precisely what is installed, under which vendor and version, on which systems, owned by whom. When that picture is incomplete or inconsistent, the findings inherit the problem.

Raynet One approaches Vulnerability Management from the asset side. Software and hardware discovered across your environment are normalized into consistent product identity, matched against vulnerability data, and enriched with the lifecycle, ownership, and business context needed to rank what is left. Risk-based Vulnerability Management then weighs criticality, exploitability, and business impact rather than CVSS alone.

The result is a shorter, more accurate list, and a defensible answer to the question every security review asks: why this one first.

Vulnerability Management

Raynet One builds Vulnerability Management on the asset intelligence it already maintains, which is what determines whether a finding is accurate in the first place.

Discovery collects software, hardware, operating system, configuration, and cloud data from across the environment through agent-based and agentless inventory and more than 200 connectors. The Raynet One Technology Catalog normalizes it into consistent vendor, product, version, edition, and model identity, then enriches it with lifecycle status, support dates, and classification.

Vulnerability information from public sources including the NIST National Vulnerability Database is matched against that normalized installed base and kept current daily. Because both sides of the match use the same product identity, findings land on the systems that genuinely run the affected software.

Scoring then applies Risk-based Vulnerability Management. CVSS is one input alongside exploitability, the criticality of the affected system, ownership, and whether the software is still supported at all. Dashboards show what changed, what is overdue, and what is heading toward a deadline, and findings route onward into patching, mitigation, or replacement.

IT failure after cyber attack: Fully operational again in just 13 days with Raynet One Vulnerability Management

An international retail group was hit by a severe phishing attack. Within just a few hours, critical systems were paralyzed – full IT visibility was missing.

Thanks to Raynet One Vulnerability Management, the company immediately gained transparency over all affected IT assets, was able to prioritize vulnerabilities, and resolve them automatically.

The result: complete restoration of the digital infrastructure in only 13 days – combined with a sustainably improved security strategy and greater resilience.

Your company, too, can use Raynet One to detect cyberattacks faster, close vulnerabilities proactively, and minimize downtime.

// Vulnerability matching

A CVE list is only as accurate as the inventory behind it

Vulnerability data is public. The NVD publishes it and every tool in the market reads the same feeds, so the feed is not the differentiator. What separates a useful vulnerability list from an unusable one is whether those CVEs were matched to the software you actually run. That match happens on product identity, and product identity is where most inventories come apart: the same application arrives from three sources under three names, Linux packages carry distribution-specific naming, and hardware and firmware advisories sit in separate CPE namespaces. Raynet One matches against a catalog built for exactly this problem:

Normalized product identity: vendor, product, version, edition, and model resolved to one canonical record, so a CVE reaches every affected install rather than only the ones that happened to be named the way the advisory was written.
Publisher resolved to the real upstream: the organization that actually develops the software, not the distributor or reseller who shipped it, which is what vendor advisories are published against.
Hardware and firmware kept distinct: hardware and operating system CPE entries are modeled separately, so a firmware advisory does not land on the wrong class of asset.
Context arrives with the finding: lifecycle status, support dates, ownership, and classification come attached, so prioritization does not need a second lookup in another system.

A scanner reports what it inferred. Raynet One reports what you have, and that difference is what decides whether the list is worth working through.

Frequently asked questions about Vulnerability Management

What is Vulnerability Management?

Vulnerability Management is the continuous process of identifying vulnerabilities in systems, applications, and networks, assessing their risk in context, prioritizing them, and remediating them before they are exploited. It covers the full loop from detection through to verified closure, not just the detection step.

What is Risk-based Vulnerability Management (RBVM)?

Risk-based Vulnerability Management prioritizes findings by what they mean for the business rather than by severity score alone. Exploitability, the criticality of the affected system, ownership, exposure, and whether the software is still supported all feed the ranking, so a Medium severity issue on a business-critical internet-facing system can outrank a High severity issue on an isolated test machine.

How is Vulnerability Management different from Continuous Threat Exposure Management?

Vulnerability Management focuses on known vulnerabilities in software and systems, matching them to assets and driving them to remediation. CTEM is broader: it takes vulnerability findings as one input alongside misconfigurations and identity risks, validates what is genuinely exploitable, and mobilizes remediation across teams and systems. Most organizations run Vulnerability Management first and grow into CTEM.

How does Vulnerability Management relate to Security Patch & Update Management?

Vulnerability Management decides what needs fixing and in what order. Security Patch & Update Management is the most common way that fix gets delivered. In Raynet One both work from the same normalized asset data, so a prioritized finding carries through to deployment without being re-matched or re-identified along the way.

What makes Vulnerability Management with Raynet One different?

The accuracy of the match. Raynet One is not a scanner; it builds vulnerability findings on the normalized asset intelligence it already maintains in the Raynet One Technology Catalog. Because vulnerability data and installed base are resolved to the same product identity, findings reach every affected system and fewer irrelevant ones reach the queue. Enrichment such as lifecycle status and ownership arrives attached to the finding, so prioritization has its context immediately.

Which data sources does Raynet One use for vulnerability information?

Raynet One draws on public vulnerability sources including the NIST National Vulnerability Database, updated daily, and correlates them with asset and product data from the Raynet One Technology Catalog and from the systems connected to your environment.
