TL;DR: Social engineering succeeds because attackers follow legitimate communication paths, not because they always break software, and Illumio’s article argues that zero trust matters most for containing what happens after trust is abused. The security model has to assume humans will occasionally grant access and then prevent that foothold from becoming a broader breach.
Editorial analysis by NHI Mgmt Group, based on content published by Illumio: “Exploiting Human Trust Still Beats Hacking Code (And How Zero Trust Helps)”.
Key questions
Q: How should security teams reduce the risk of human trust being abused for initial access?
A: Build stronger verification into everyday approval paths, especially for payments, password resets, supplier changes, and support requests.
Q: Why does social engineering still work even when employees are trained?
A: Because training lowers risk but does not eliminate the human tendency to trust familiar cues, especially when the message is urgent or context-rich.
Q: What breaks when trusted users become part of an attack path?
A: The usual separation between authorised activity and malicious activity breaks down because the attacker is operating through a valid identity.
Practitioner guidance
- Harden approval paths around routine requests Add extra verification for purchase orders, invoice changes, support requests, and credential reset workflows so familiarity does not equal trust.
- Segment likely post-click access paths Map the systems most likely to be reached after phishing or impersonation and limit lateral movement with explicit network and identity boundaries.
- Reduce reliance on user judgment alone Use policy, mailbox filtering, conditional access, and workflow controls so employees are not the only line of defence against convincing lures.
Bottom line: The article shows that social engineering succeeds by blending into legitimate business routines, which makes human trust a primary entry condition rather than a side issue.

Human trust is the true initial access layer: The article shows that attackers often succeed by fitting into normal business routines rather than defeating technical controls. That means the first security failure is frequently a human decision under familiar conditions, not a malware event. For identity programmes, this is a reminder that authentication strength alone does not stop a convincing request from becoming access.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How do Zero Trust controls help after a phishing or impersonation attempt succeeds?
A: They limit the blast radius. Zero Trust does not stop every scam, but it can prevent a compromised user, device, or session from moving freely through the environment. Strong segmentation, explicit authorization, and continuous verification make the attacker’s next step much harder to convert into broader compromise.
