Filter Out the Noise
Since I started this curated security news in June 2017, I’ve clipped ~19,000 articles and narrowed them down into the best 20 per day & best 15 per week. This is my favorite way to cut through all the security marketing and hype. If you’re enjoying it, tell a friend. If you hate it, tell an enemy.
Thanks! – Lucas Samaras
