  • Legion had a great week in Tampa at the 2026 H-ISAC Spring Americas Summit! We are proud to participate as a Hospitality Sponsor among other cybersecurity leaders, practitioners, and innovators from across the industry. It was an incredible opportunity to connect with peers, exchange insights, and discuss the evolving challenges organizations face in protecting critical healthcare environments. A special thank you to our Sr. Enterprise Account Executive, Chris Burrows, for representing Legion Security throughout the event, engaging with attendees, and participating in valuable sessions and conversations. We appreciate Health-ISAC for bringing together such a collaborative and impactful community focused on strengthening cybersecurity resilience across the healthcare sector. Looking forward to continuing the conversations and partnerships that started this week!

  • Two years ago, Legion Security started with a conviction and a whiteboard. Today, we're building the future of cyber defense. When we set out, the security industry was loud with tools and quiet on outcomes. We believed defenders deserved better: fewer dashboards, less noise, more leverage. That belief became Legion Security. Year two has been about the people who turn that belief into reality. We've grown from a small founding crew into a team of engineers, researchers, designers, and operators who choose to spend their careers protecting others. We've welcomed leaders who've defended some of the most targeted organizations on the planet. We've built a culture where curiosity is currency, and where every hire raises the bar for the next one. To the Legion Security team: thank you for showing up with rigor, heart, and a refusal to accept "good enough". To our customers and partners: you trusted us early. You shaped what we built. You're the reason this anniversary matters. Year three is already in motion. Bigger threats, smarter adversaries, higher stakes, but we're a unified team that's ready for it all. Cheers to the defenders! #legionsecurity #anniversary #2yearsofsuccess #threatdefenders

  • Mythos ended the debate about whether AI belongs in the SOC. What it didn't end: the question of how to deploy it right. Most AI SOC implementations are failing for the same reason: it's a missing the organizational context that shapes how your business actually operates. A heavily regulated enterprise running investigations across proprietary internal platforms looks nothing like a tech company. Systems that only see tool outputs miss the mark And here's what most vendors won't tell you: organizational context isn't a one-time setup. Teams change. Tools get added. Risk posture shifts with every acquisition. An AI that ingested your environment six months ago is already making decisions based on an organization that no longer exists. The only durable path is moving quickly on the version that actually holds up. Ron Marsiano breaks down what good implementation actually looks like, and why most teams are about to learn the hard way that fast and right aren't the same thing.

  • Our CEO & Co-founder, Ely Abramovitch, was recently featured in the Motions & Tailwinds Report by Software Analyst Cyber Research and Deutsch & Co. "What we actually want to measure is that the AI is accurate, comprehensive, and that it takes on work that is actually valuable." Thanks to our friends at SACR and D&Co! Check out the full report here: https://lnkd.in/eVcWjY6t

  • Mythos changes the math for defenders. Zero-day vulnerabilities that previous models missed. Multi-path exploits at scale. Capabilities that used to require nation-state resources are now in reach of a much broader set of threat actors. Static detections were never going to catch dynamic adversaries. That's about to be obvious to everyone. The path forward isn't more signatures. It's AI that meets SOC teams inside the tools, processes, and guardrails they already operate in. That's what Legion Security does. Our CEO Ely Abramovitch on what comes next: https://lnkd.in/eVWiYbak

  • Every SOC analyst knows the drill. Eight tabs open. CrowdStrike in one window, VirusTotal in another, Defender running a hunting query in a third. And somewhere in between all of it, documenting screenshots, log entries, and case notes. Most AI SOC platforms give you a verdict and a reason. But if you ask what the agent actually saw, you get API logs and structured JSON. That's not evidence. That gap between what an AI did and what you can verify is exactly where the risk of hallucinations lives. A summary can sound confident and still be completely wrong. That's why we built Evidence Gathering. Legion Security navigates your actual source systems through the browser, the same way your analysts do. It opens the real interface, reads the real screen, and captures a screenshot of exactly what it sees at every step. Automatically. In real time. By the time an analyst opens a case, the full evidence gallery is already there. Screenshots are organized sequentially, labeled by tool, timestamped, and ready to review. Every investigation is stored and searchable. Nothing reconstructed. Nothing missing. The bar doesn't move because the analyst is an AI. It stays exactly where it's always been. See Evidence Gathering in action with Gili Diamant here: https://lnkd.in/eqnc6vHs
