💪 This past October, Cybersecurity Awareness Month reminded us that awareness isn’t enough–action is. Penetration testing gives organizations a clear-eyed view of their true security posture, helping teams turn insight into defense. It’s more than testing systems–it’s strengthening people, processes, and awareness. At Cobalt, we believe continuous pentesting is key to building resilient organizations that learn, adapt, and stay secure in a constantly evolving threat landscape.

🌴 That’s a wrap on #InfoSecWorld Orlando! From insightful conversations at Booth #313 to our CISO Andrew Obadiaru, CISM, CRISC, MCP’s session on how AI is reshaping the security landscape, last week was all about helping organizations prepare for what’s next. Andrew shared practical strategies for securing LLMs and tackling the final 10% of AI-specific risks that traditional defenses often overlook—a topic that sparked some great hallway conversations. Thanks to everyone who stopped by to connect with the Cobalt team. Until next time! #cybersecurity #pentesting #infosec

🧛♀️ Beware of the vulnerabilities lurking in your supply chain… From Log4Shell to MOVEit, we’ve seen how one vulnerability can haunt thousands of organizations. The problem? While 94% of security leaders believe pentesting is essential, only 40% require it from their vendors. 👻 The result is a chilling assurance gap that leaves every dependency an open door for attack. 🔒 Our latest blog breaks down the findings from our 2025 State of Software Supply Chain Security report and what steps leaders can take to address hidden risks. 🎃 Read here → https://hubs.la/Q03QYbZr0 #cybersecurity #infosec #pentesting
