How Smarter Exploitability Analysis Transforms Product Security: Reachability Expansion

In connected device security, the hardest part isn’t finding vulnerabilities; it’s figuring out which ones actually matter. Teams are overwhelmed with alerts, timelines are tight, and development never stops. Every extra minute spent on triaging false positives or chasing non-issues is time taken away from fixing the vulnerabilities that pose real risk.

That’s why Reachability has become one of the most impactful capabilities in the Finite State platform and why expanding its precision, breadth, and speed unlocks a fundamentally better way to manage risk at scale.

The Problem: Vulnerability Overload Has Become the Status Quo

Across IoT, embedded systems, industrial devices, and automotive, security teams face the same dilemma:

• Thousands of third-party dependencies
• CVEs with limited context
• Complex firmware and system interactions
• Tight product development cycles
• Growing regulatory demands

And yet, most tools still treat every vulnerability as equal.

This leads to:

• Endless triage cycles
• Developers patching code that isn’t actually exploitable
• Uncertainty about what needs attention first
• Delayed releases
• Rising operational security debt

Teams don’t need more vulnerability data — they need data that tells them what matters.

Reachability’s Expansion Is Really About Precision, Not Volume

With coverage expanded to more than 90% of detected CVEs, Reachability gives teams visibility into almost every vulnerability discovered in their firmware, SBOMs, or source code. But the breadth is only part of the story.

The real value is in what Reachability enables:

1. Cutting Through the Noise at Scale

When most CVEs aren’t exploitable in a real-world context, expanding reachability means teams can automatically eliminate the majority of non-issues from their backlog.

Less noise.
Less triage.
More clarity.

2. Accuracy That Drives Confident Decisions

Through new input vector analysis, Reachability identifies the data paths that actually lead to vulnerable functions. This is a shift from theoretical risk assessment to evidence-based exploitability.

Teams gain:

• High-confidence prioritization
• Fewer false positives
• Defensible reasoning behind risk decisions

This isn’t just better vulnerability analysis, it’s better judgment.

3. Faster Workflows Across Security and Development

With sub-hour analysis times and default enablement, Reachability now fits naturally into product security workflows without slowing them down. Teams can run more scans, validate more changes, and reduce the time spent waiting for results.

It becomes a continuous signal, not an occasional check.

Real-World Impact: What Teams Actually Experience

Across our customers, the expanded Reachability capabilities translate into several tangible improvements.

Dramatically Reduced Backlog

Teams can deprioritize the vast majority of unreachable findings, shrinking thousands of CVEs down to a manageable set of actionable security issues.

Accelerated Release Cycles

Developers spend less time patching unexploitable vulnerabilities — which means more time building features and shipping updates.

Improved Cross-Team Alignment

Reachability gives product security, engineering, and leadership a shared understanding of the risks that truly matter.

Higher Confidence in Security Posture

Decisions are based on evidence, not assumptions. Teams know not just what is vulnerable, but how and whether it can be exploited.

Better Compliance Outcomes

With rising expectations from regulations such as the EU Cyber Resilience Act, NIS2, and PSTI, demonstrating exploitability analysis is a strategic advantage.

Why This Expansion Positions Finite State Ahead of the Market

Many tools offer reachability, but few (if any) provide high-accuracy, device-focused exploitability intelligence across more than 90% of detected CVEs — in under an hour — enriched with exploit data.

This combination of breadth, depth, and speed puts Finite State in a unique position to help manufacturers secure increasingly complex device ecosystems.

It’s not just an enhancement.
It’s the foundation for a more efficient, more precise, and more scalable security program.

What’s Next

Reachability will continue to evolve as new CVEs are discovered, new exploit techniques emerge, and device architectures grow more complex. This expansion is one step in an ongoing effort to give teams the clarity they need to operate confidently in a rapidly shifting threat landscape.

For now, the impact is clear:
Security and development teams can prioritize smarter, move faster, and build more secure devices — without drowning in noise.
