Featured Reviews

Amran Hossain - PeerSpot reviewer
Training program enables comprehensive security awareness and cautious email practices
One feature that would be highly beneficial in a future release is the ability to automatically send training articles or security tips to users on a regular, scheduled basis—for example, weekly or monthly. While the current training modules and phishing simulations are highly effective, ongoing awareness is equally important to keep security top of mind in day-to-day operations. These short, digestible articles or micro-learning content could cover recent phishing trends, real-world examples of security breaches, or quick tips on secure online behavior. Periodic delivery would serve as a continuous learning touchpoint, reinforcing key concepts from the main training and adapting to evolving threats. Ideally, this feature would also include personalization, allowing content to be tailored based on a user’s role, previous training performance, or common mistakes observed in phishing simulations. This kind of proactive, lightweight training approach could significantly enhance employee engagement with security practices and help maintain a strong security posture over time.
