TL;DR: A 224% ROI, $3.8 million NPV, over 25% breach-risk reduction, and 2.5 hours of weekly analyst effort were modeled in Forrester Consulting’s TEI study for a 20,000-endpoint composite enterprise, according to Airlock Digital. The finding reinforces that deny-by-default application control is now as much a governance and operational discipline as an endpoint security control.

Key questions
Q: What breaks when application control is not enforced on endpoints?
A: Without application control, endpoints will run far more code than the organisation can reliably trust.
Q: Why does deny-by-default application control reduce breach risk?
A: It reduces risk because many attacks depend on getting code to execute in the first place.
Q: What do teams get wrong about application control in modern endpoint environments?
A: A common mistake is treating application control as a blocking tool rather than an operational control that improves visibility and trust decisions.
Practitioner guidance
- Define an approved software execution baseline Build a deny-by-default policy from a verified inventory of business-approved binaries, scripts, and installers, then map exceptions to named owners and expiry dates.
- Tie exceptions to operational ownership Require every application control exception to include a business justification, review date, and rollback path so temporary access does not become permanent trust.
- Measure execution-policy coverage separately from alert volume Track how much of the endpoint estate is governed by the allow model, how many unapproved execution attempts are blocked, and how long exceptions stay open.
Bottom line: Application control reduces risk by constraining what code can execute, which changes the attacker’s path before malware or ransomware can take hold.

Application control is now a governance control, not just an endpoint hardening feature. The article’s strongest signal is not the ROI figure itself but the shift in how buyers should value execution policy. When software execution is tightly governed, security and software inventory become linked operating disciplines. Practitioners should treat the allow model as part of identity-adjacent access control for code.
A question worth separating out:
Q: How should organisations judge the value of application control?
A: They should judge it on both security effect and operating cost. A useful control should reduce the set of executable software, lower the chance of malicious code running, and remain manageable for the team that owns it. If a policy cannot be operated with clear ownership and routine review, its theoretical security value will not hold up in practice.
