Haekka

Haekka is an employee security and compliance training platform built natively inside Slack. It delivers microlearning in the flow of work through bite-sized training modules, security awareness streams, phishing simulations, and automated workflows—all without requiring employees to leave Slack. Haekka supports security awareness, compliance, onboarding, product knowledge, and customer success training. The platform is designed to boost engagement and drive near-universal completion rates by meeting employees where they already work. Haekka was acquired by Hook Security Co. in March 2025.
