    And that’s a wrap on Infosecurity Europe 2026! What an incredible few days at ExCeL London. A huge thank you to everyone who stopped by to chat about the future of Pentesting as a Service (PTaaS) and offensive security. A special shoutout to everyone who packed the room for Cobalt CTO Gunter Ollmann’s session on autonomous offensive security.  If we didn't get a chance to connect, or if you want to keep the conversation going about scaling your security program, you can reach out to the team and schedule a demo here → https://hubs.la/Q04kp1_q0 See you next year, London! 🇬🇧✈️ #cybersecurity #pentesting #infosec

    You don't need a zero-day when the classics still work. Cross-Site Scripting. Missing Access Control. Server-Side Injection. Business Logic flaws. CSRF. These are some of the most common findings uncovered in pentests today—and many remain unresolved long after they're discovered. In fact, 61% of XSS findings and 60% of Server-Side Injection findings remain open. In this video, Cobalt Core member Harsh Bothra shares a pentester's perspective on why attackers keep coming back to these vulnerabilities, how they turn seemingly simple flaws into major compromises, and what security teams should be paying attention to.

    For years, security programs operated under a simple assumption: defenders would have time... But what happens when vulnerability discovery, validation, and exploit development begin operating at machine speed? CISO Andrew Obadiaru, CISM, CRISC, MCP shares his perspective on Mythos, why traditional vulnerability management assumptions are weakening, and why security maturity will increasingly be measured by exposure reduction speed, not simply patch compliance percentages.
