TL;DR: Attackers use trusted inboxes to trigger fraud, identity changes and breach paths, SecurityScorecard reports. Email workflows need independent checks before resets, approvals or delegated access change hands.
Editorial analysis by NHI Mgmt Group, based on content published by SecurityScorecard: “The Importance of Email Security”.
Key questions
Q: Why do email compromises so often lead to broader cloud and data loss incidents?
A: Email is often the first foothold because attackers use phishing, impersonation, or stolen credentials to enter a user account.
Q: What are the signs that email trust controls are failing?
A: Repeated replies to suspicious requests, high forward rates, weak reporting discipline, and inconsistent escalation around vendor changes are all warning signs.
Q: What breaks when email is treated as a trusted identity signal?
A: When email is treated as authoritative, attackers can use one compromised or impersonated mailbox to trigger password resets, approve fraudulent requests, or alter delegated access.
Practitioner guidance
- Strengthen sender authenticity controls Enforce SPF, DKIM and DMARC, then monitor for unauthorised senders and spoofed lookalikes that bypass policy.
- Protect account recovery paths Review password reset, mailbox delegation and help desk recovery processes so email cannot be used as a weak proofing channel.
- Separate approvals from ordinary email trust Require step-up verification for payments, access changes and sensitive disclosures that arrive by email.
Bottom line: Email security failures matter because attackers use trusted inboxes to reach identity, fraud and breach outcomes rather than simply to deliver unwanted messages.

Email security is now an identity governance problem, not just a content-filtering problem. The article is correct that email is where trust is operationalised, because approvals, resets and supplier communications often depend on it. Once those workflows are abused, the security failure is no longer about spam volume, but about who or what was allowed to act on a message. Practitioners should therefore align email controls with identity assurance, not only with perimeter filtering.
A question worth separating out:
Q: How should security teams govern email risk across third-party relationships?
A: Treat vendor email as part of the trust perimeter. That means validating partner domains, restricting what partner messages can authorise, and monitoring for impersonation of suppliers that can trigger financial or operational change. Third-party risk reviews should cover communication integrity as well as infrastructure controls.
