Have you heard the phrase "to move stones"? 💡 It symbolizes taking on tough tasks, no matter how small, with persistence. From ancient builders to cultural metaphors, it’s all about steady progress toward bigger goals. #Motivation #Perseverance #Leadership

Just added my notes on Sitreps to my book project. Todays topic is on an important tool to ensure good communication with stakeholders in #SOC, #IncidentManagement and #ThreatHunting scenarios! I hope you like it! :)

Attended an inspiring presentation on change management tonight! Learned something new and realized the value of seeking mentorship outside of work. It broadens your perspective—echo chambers can be dangerous for growth. #ChangeManagement #Mentorship #Growth

Interesting how #Microsoft conveniently lists all the URLs their Attack Simulation Training (#phishing) tool uses on the 'Get Started' page. Nice to know, I suppose.
