Frequently Asked Questions
Email Security FAQs
Answers to common questions about email threats, authentication and business email protection.
Email security combines technical controls, identity protection, monitoring and response processes to reduce risks from phishing, spam, spoofing, malware, account compromise and unauthorized disclosure.
Business email compromise is a type of fraud in which attackers impersonate or compromise trusted business accounts to persuade people to transfer funds, disclose information or change payment details.
These email authentication mechanisms help receiving systems evaluate whether messages are authorized and authenticated for a domain. Correct configuration can reduce spoofing risks, though it does not prevent every phishing attack.
Email security engagements can include reviews of supported Microsoft 365 and Google Workspace settings, account protection, authentication, administrative privileges and email security policies, depending on the agreed scope and available licences.
Follow your incident response process promptly. Secure the account, revoke suspicious sessions where supported, reset credentials, verify MFA, review forwarding rules and mailbox permissions, investigate message activity and notify affected parties where appropriate.
No. Filtering should be combined with strong authentication, domain protection, access controls, user awareness, monitoring and a defined incident response process. No single control eliminates all email threats.
