Partnership overview
Where QuestSys and Doppel create customer value
Customers may already have strong controls around infrastructure, networking, communications, and access-control expertise; the gap Doppel targets is the attacker-controlled infrastructure and human manipulation behind phishing, brand impersonation, and credential theft. Across Digital Risk Protection, Human Risk Management, and Email Security, the platform links external threat detection with automated action and threat-informed simulation, creating a feedback loop between what attackers are doing and how the organization prepares. For the customer, the value is a single social engineering defense motion that can start with one urgent use case and expand as the program matures.
How we work together

Give operations more campaign context in QuestSys-led programs
Use QuestSys' context around infrastructure, networking, communications, and access-control expertise as the starting point. Use Doppel’s graph-driven intelligence to connect external indicators into the broader incident and response workflow.

Use QuestSys' context around infrastructure, networking, communications, and access-control expertise as the starting point. Use simulations based on real social engineering tactics to test how employees respond when attackers target trust rather than technology.
