Send continuous reminders and security updates through email and chat platforms is correct. This option describes embedding short, timely cues into the tools employees use every day so awareness becomes a continuous part of normal workflows.

Continuous reminders and updates are low friction and support spaced repetition which improves retention. They can be targeted and contextual so messages align with current threats and specific roles. They also allow rapid distribution of alerts about active phishing campaigns and encourage habitual vigilance without blocking productivity.

Publish short interactive microlearning lessons on the company intranet is useful as a resource but incomplete. Intranet lessons rely on staff to visit the site and pull the content which reduces frequency and the likelihood of repeated exposure compared with push notifications in email and chat.

Assign security related tasks as part of normal job responsibilities may create checkbox behavior and additional operational burden. Some security controls are best handled by specialists and assigning tasks broadly can produce inconsistent outcomes and does not ensure ongoing awareness reinforcement.

Require completion of a full training course before granting access to internal systems enforces compliance but is high friction and episodic. A one time course is easy to forget and it can delay access and productivity. Continuous reminders and updates are better for keeping staff alert over time.
