We just hit a major milestone: No. 1 in security and No. 121 overall on the 2025 @Inc 5000 list — with 2,962% growth in three years. 🔥 The takeaway? Offensive security isn’t the future — it’s here. Organizations are turning to #AI hackers and the attacker’s perspective to find, fix, and verify the issues that actually matter. Huge thanks to our customers, partners, and the incredible Horizon3.ai team for making this happen. We’re just getting started! #Inc5000 #OffensiveSecurity #cybersecurity #NodeZero

Not sure if you’re exploitable? Our #NodeZero Rapid Response test for CVE-2025-20362, CVE-2025-20333, and CVE-2025-20363 can quickly prove exploitability and validate your remediation. 👉 Visit horizon3.ai/attack-research/… to learn more and run the test now.

While it’s been over a month since the initial advisory and revelation of 0-day exploitation of these vulns, there are still unpatched devices. Attackers are making the most of those instances, leveraging the vulnerabilities to find new ways to impact and disrupt businesses.

👀 Cisco ASA/FTD vulnerabilities are officially back in the news, and it’s not good. Active exploitation continues and there are new attack variants on devices vulnerable to CVE-2025-20333 and CVE-2025-20362. The attacks may result in unpatched devices unexpectedly reloading, leading to denial of service (DoS): sec.cloudapps.cisco.com/secu…

That’s a wrap on @CrowdStrike fal.con Europe! We brought the attacker’s perspective to Barcelona — showcasing exactly how #NodeZero helps defenders validate, tune, and prove the effectiveness of their EDR. A huge thank-you to everyone who joined us at the booth and attended our speaking sessions! We’re fired up to keep helping organizations stay ahead of attackers and get the most out of their EDR investments. 🔥 #EDRHealthcheck #EndpointSecurity #pentesting

Big things are coming! On November 12, Horizon3.ai Sr. Technical Product Manager Brad Hong will go deep on how the #NodeZero MCP Server is transforming how organizations operationalize autonomous security. You'll learn how to: ⚡ Leverage NodeZero findings to feed LLMs precise, real-world data about your environment. ⚡ Operationalize the full Find → Fix → Verify loop injected with additional org context from other MCP servers ⚡Explore what's possible when the NodeZero MCP Server becomes a cornerstone for autonomous workflows, from security orchestration to incident response acceleration. 📅 Don’t miss this one — save your spot: event.on24.com/wcc/r/5120218… #MCPServer #AI #automation #pentesting

We’re proud to be no. 2 on the @SFBusinessTimes list of Fastest-Growing Private Companies in the Bay Area! 🎉 This recognition reflects our continued growth, and the momentum behind organizations adopting autonomous, evidence-based security to stay ahead of attackers. Thank you to our customers, partners, investor community, and team for driving what’s next in offense-driven defense! #NodeZero #OffensiveSecurity #pentesting

You trust your EDR to catch what matters, but when was the last time you proved it? #NodeZero’s EDR Healthcheck safely emulates real-world attacks in production to show exactly what your endpoint controls detect, block, or miss. You’ll see: 🔍 Technique-level results mapped to MITRE ATT&CK 🕵️ Host-by-host outcomes with timestamps and command logs 🧩 Gaps in detection logic or policy coverage All agentless. All safe in production. Stop assuming coverage — validate it. 🔗 Run your EDR Healthcheck: horizon3.ai/edr-healthcheck/… #EndpointSecurity #OffensiveSecurity #pentesting

Shutdown got you down? 🍻 Take a break from the chaos and join us tomorrow night at Jailbreak Brewing in Laurel, MD. We’re bringing together cyber pros for good conversation, cold drinks, and insights into our Attack Engineer and Vulnerability Research roles. No agenda, no PowerPoints — just great people and great beer. RSVP at eventbrite.com/e/shutdown-so…. #HappyHour #cybersecurity #infosec

#AI is already shaping business decisions across the enterprise. It's time security caught up. Most automation in vulnerability management is still built on shaky data: scanner output, CVE databases, and CVSS scores. The result? Agents chase “critical” findings that aren’t exploitable, while medium-severity weaknesses quietly open paths to domain admin. #NodeZero MCP Server changes that equation. By feeding exploit-verified evidence into AI workflows, enterprises can finally blend real attacker proof with business context, transforming from reactive triage centers to systems that systematically close proven attack paths. This is the foundation for #FixOps: continuous Find–Fix–Verify loops where #AI acts on verified exploitability to drive immediate remediation and confirm every fix, so your team closes real exposures fast, not just discovers vulnerabilities faster. Your AI doesn’t need more data. It just needs better data — the kind only NodeZero provides. 👉 Read our full blog: horizon3.ai/intelligence/blo… 🔗 Architectural considerations for building FixOps: horizon3.ai/intelligence/blo…

We’re proud to be sponsoring Distology Disruptor Day UK 2025, a premier event bringing together cybersecurity innovators, technology partners, and disruptors shaping the future of defense. 🇬🇧 Our team will be on site showcasing how #NodeZero empowers organizations to continuously find, fix, and verify exploitable attack paths — turning offensive insights into measurable resilience. 🔗 Learn more and register at distology.com/news-events/di…. #NodeZeroPartner #OffensiveSecurity #pentesting

FedRAMP 20x demands agility: CSPs must maintain proof of controls, and 3PAOs must evaluate them in real time. #NodeZero Federal™ enables daily assurance through continuous, automated pentesting — no scrambling before submissions, just readiness on demand. 👉 Learn more: horizon3.ai/use-case/use-cas… #FedRAMP hashtag#OffensiveSecurity hashtag#pentesting
