What it checks
SCuBA MS.EXO.11.2 recommends that user warnings comparable to EOP safety tips be displayed. Safety tips surface automated signals (unusual characters in the FROM address, first-contact senders) directly in the client, prompting caution at the moment of risk. This offloads detection work from users and reduces successful phishing.
Recommended value
Anti-phish policy with first-contact safety tips and spoof/impersonation safety tips enabled
Remediation
Enable the safety tip options in the anti-phish policy, including first-contact safety tips and spoof and impersonation safety tips, so users receive in-client warnings. Apply the policy to all users. Where a comparable third-party solution is used, confirm it presents equivalent recipient-facing warnings.
Fixture-proven verdicts
Every verdict below is proven by a golden fixture in the module's gating test suite. This table derives from the last green run; it cannot be edited by hand.
| Scenario | Expected verdict |
|---|---|
| clean | PASS |
