Reducing False Positives in Vulnerability Management Through Deterministic Testing

Toronto, Canada - September 18, 2025

Why deterministic models succeed where scanners flood teams with noise

Most organizations are overwhelmed by vulnerability scan results. Traditional scanning tools flag thousands of potential issues, but many are false positives or irrelevant in context. This creates alert fatigue and wastes remediation resources. SEAS and CypSec use deterministic penetration testing to separate exploitable attack paths from harmless noise.

Deterministic testing goes beyond listing vulnerabilities. It models the environment as a graph of assets, trust relationships, and privilege boundaries, then calculates which vulnerabilities actually enable attack paths to critical systems. This means only findings that materially contribute to compromise are prioritized.

In practice, this often eliminates over 90% of scanner findings from active remediation queues. SEAS frequently observes that many flagged CVEs reside on isolated systems with no trust links to valuable assets. These pose negligible real risk, yet consume significant patching effort in traditional workflows.

Conversely, deterministic analysis highlights low-severity issues that create critical attack paths when combined. Traditional tools miss these chained risks because they evaluate vulnerabilities in isolation rather than as components of an exploit path.

"Deterministic testing filters vulnerability noise down to the few issues that actually matter — and proves why they matter," said the SEAS Research Team.

By showing exactly how each vulnerability contributes to compromise, deterministic testing enables precise risk scoring. Security teams can focus on the small subset of weaknesses that directly enable lateral movement, privilege escalation, or access to crown-jewel assets — and deprioritize everything else.

This improves not only efficiency but also credibility. Executives and risk committees receive clear, defensible reasoning for why specific issues are addressed while others are deferred, something that traditional vulnerability reports cannot provide.

SEAS and CypSec integrate this approach into CypSec’s risk management platform, enabling organizations to unify vulnerability data with deterministic exploitability analysis for continuous, evidence-based prioritization.
