Explanation

DLP (Data Loss Prevention) is specifically designed to inspect outbound messages for sensitive data - such as PII, financial records, or intellectual property - and prevent that data from leaving the organization, making it inherently an outbound-only control.

Why the distractors are wrong:

B (Anti-Virus): Scans both inbound and outbound messages for malicious attachments and files, so it's bidirectional.
C (Anti-Spam): Primarily an inbound filter that blocks unwanted or unsolicited email before it reaches users' inboxes.
D (Outbreak): Outbreak filters detect emerging threats (e.g., zero-day phishing campaigns) and apply to inbound traffic to stop threats before signatures exist.

Memory tip: Think of DLP = Data Leaving Prevention - if data is leaving your org, DLP is watching. All other filters are guards at the front door (inbound), while DLP is the guard at the back door (outbound).
