Revealing every path an attacker could take — not just the obvious ones.
Toronto, Canada - September 18, 2025
Traditional penetration tests reveal only the attack paths that happen to be found during time-limited engagements. This leaves large parts of the network's attack surface unexplored and unquantified. SEAS and CypSec’s deterministic approach replaces this trial-and-error model with complete attack path enumeration using formal network graphs.
In deterministic testing, the network is represented as a graph of nodes (hosts, accounts, services) and edges (trust relationships, credentials, allowed communications). Each edge is labeled with conditions for traversal, such as required privileges or known exploits. This structure enables the calculation of every theoretically valid path from an entry point to high-value targets.
This method reliably uncovers hidden routes that red teams often miss. SEAS frequently identifies multi-step paths involving low-privileged accounts, chained misconfigurations, or forgotten legacy systems that attackers could exploit to bypass defenses entirely — paths that are invisible to heuristic pentesting.
Deterministic modeling also reveals chokepoints: nodes or credentials that appear on many attack paths and whose compromise would enable broad access. These are critical risk reduction points. Reinforcing or isolating them often eliminates dozens of potential attack paths at once, providing far more leverage than patching isolated vulnerabilities.
"You cannot defend what you have not mapped. Deterministic attack path graphs show every route an attacker could take — not just the ones we happen to find," said the SEAS Research Team.
Because the model enumerates all paths, not just those found by trial, it provides a complete view of lateral movement potential. This gives security architects and risk managers hard data for prioritizing segmentation, privilege redesign, and monitoring coverage with maximum impact.
SEAS and CypSec integrate this path modeling into CypSec’s risk management platform, allowing organizations to link each path to its associated assets, business impact, and existing controls. This bridges the gap between raw penetration test findings and strategic risk governance.
Where conventional pentests stop at "proof of compromise," deterministic testing continues to "proof of all possible compromise." This gives organizations a defensible basis for asserting coverage and demonstrating improvement over time.
