Remote work has permanently expanded the email threat surface. Employees log in from home networks, shared spaces, and multiple devices — creating more opportunities for credential theft and phishing.
Email remains the most common entry point for cyberattacks.
This playbook outlines the essential controls modern remote teams should implement.
MFA should be mandatory for:
Credential theft alone should not allow access.
Older protocols that allow basic username/password authentication are vulnerable to brute-force attacks.
Disable:
Modern token-based authentication significantly reduces attack vectors.
BEC attacks impersonate executives or finance teams.
Mitigation steps:
Process controls are as important as technical controls.
Attackers often create hidden mailbox forwarding rules after compromise.
Audit:
Log and review administrative changes regularly.
Use:
Remote environments increase interception risk.
Technology alone is insufficient.
Train teams on:
Education reduces successful attacks significantly.
Have a documented playbook for:
Quick containment prevents lateral spread.
Remote work is here to stay. That means email security must be proactive, layered, and continuously monitored.
Security is not a single feature — it is an operational mindset.
Build defensively, monitor consistently, and assume attackers are persistent.
