Frequently Asked Questions
Frequently asked questions
How does it compare with Trend Email Security?
Trend's Writing Style DNA BEC detection is more advanced; Bitdefender has a clear price advantage. SMBs and mid-market typically choose Bitdefender; enterprise BEC use cases lean toward Trend.
Do I need to change my MX record?
No — API-based. Graph API (Microsoft 365) or Gmail API access reads and acts on email without touching the mail flow.
How much latency does the sandbox add?
Known files pass through with no delay; sandboxed files add 60–120 seconds on average.
How is ATO detection performed?
Login patterns, IP, device fingerprint and behavioral anomaly analysis surface compromised accounts.
Is there a user self-service portal?
Yes. Users can browse quarantined mail and request release within policy bounds.
Are DLP policies GDPR-aligned?
Yes. Pre-built regex templates cover national ID numbers, IBAN, credit card and phone numbers — GDPR Article 32 aligned.
Is there an Outlook plugin?
Yes — a phish-reporting plugin lets users one-click report suspicious mail.
