Abstract Security just sealed the deal on a $15M Series A, and they didn’t even break a sweat. Munich Re Ventures led the round, with Crosslink Capital and Rally Ventures throwing down too. Why? Because Abstract isn’t here to patch up broken enterprise security—they’re out to tear it down and build something actually built for the future. Colby DeRodeff, Ryan Clough, and Aaron Shelmire know the game cold. With stints at ArcSight and Mandiant, they’ve seen every outdated SIEM and bloated security setup out there. So, they didn’t just add some AI stickers and call it a day. They built a platform that actually works—AI-powered, real-time data streaming that splits compliance from security like it’s second nature. No more noisy alerts. No more wasted storage. Just faster detection, tighter data flows, and lower costs. This $15M? It’s not just a win—it’s fuel to push the boundaries even further. Cloud visibility? About to get sharper. Data stream optimization? Locked in. And SIEM? It’s finally going to start pulling its weight. If your platform doesn’t look like this, you’re not just behind—you’re running in the wrong race. Colby summed it up perfectly: “The future of detection isn’t in the hype, it’s in the data. When you bake detection engineering into the platform with real analytics, you’re not just ahead—you’re untouchable.” Congrats to Abstract Security for pulling off what the industry should have been doing all along. The cybersecurity game just leveled up, and if you're not watching, you’re already falling behind. #CyberSecurity #SeriesA #AI #DataStreaming #DataOptimization #SIEM #Security #AISecurity #VentureCapital #StartupFunding #SeriesA #Technology #Innovation #Detection #Analytics

Securing the Future of GenAI: Prompt Security's Series A Milestone 🎉 I couldn’t be prouder to announce that Prompt Security has secured $18 million in Series A funding, led by Jump Capital with participation from Hetz Ventures, Ridge Ventures, and tech giants Okta and F5. This milestone is a testament to the dedication of our team, now 30 employees strong, the trust of our customers, the collaboration with our partners, and the unwavering support of our investors. Just 10 months ago, we emerged from stealth with a clear mission: to enable enterprises to harness the power of Generative AI safely and securely. In this short time, we've witnessed exponential growth in both GenAI adoption and its associated risks, underscoring the urgent need for comprehensive GenAI Security. At Prompt Security, we've risen to this challenge, and our growth has been remarkable: We’ve quadrupled revenue and grown our customer base fivefold, including Fortune 500 companies. But we’ve also achieved recognition beyond our core business, whether it was with the Prompt Fuzzer - the first open-source vulnerability assessment tool for GenAI Apps -, winning the CPX Innovation Sandbox, gaining recognition in a dozen Gartner Hype Cycles, or being part of the seventh cohort of Deloitte Launchpad. The urgency of our mission is clear: almost 30% of enterprises deploying AI have experienced an AI security breach. This new funding will help us expand our geographic footprint and presence across industries, protecting more enterprises from GenAI threats while offering clear visibility into and governance over GenAI tools. Security should be a catalyst for innovation. I look forward to reaching new heights as Prompt Security builds a secure future for GenAI, one enterprise at a time.

Realm.Security Emerges From Stealth With $5 Million in Seed Funding: Realm.Security has emerged from stealth with $5 million in funding and a solution that helps organizations manage security data.  The post Realm.Security Emerges From Stealth With $5 Million in Seed Funding appeared first on SecurityWeek.

Last week, I had the pleasure of speaking with Fahmida Y Rashid about Abstract’s emergence from stealth and $8.5M Seed round investment led by Crosslink Capital, Rally Venturesand Liquid 2 Ventures. Thanks Tom Reilly and Matt Bigge for contributing their perspective to the conversation. Every day I wake up feeling grateful to work on solving a problem that I saw developing in the market in 2002, but this conversation especially reignited my purpose, and I look forward to continuing to work closely with our talented team and beta-customers as we refine Abstract’s security analytics platform. Our mission is simple: to deliver on the promise that current offerings fall short of, while lowering costs. By giving security analysts access to the tools they need to correlate data in real-time between streams, separate compliance, and security data to increase detection effectiveness, analysts can focus on the threats that matter.

I’m thrilled to share that Traceable API Security has raised a $30 million strategic investment round 👏 More and more businesses are tapping APIs — in part thanks to the generative AI boom — but in the process, they’re unwittingly exposing themselves to attacks. There's still a lack of recognition of both the criticality of API security as well as the ever-growing attack surface in APIs. Due to entrenched investments in security solutions that don’t address the API security problem, this key piece of the security equation is often overlooked. When Sanjay Nagaraj and I started Traceable, we were driven by the mission to make every API a source of secure innovation and remove any potential risks. Today, we are more motivated than ever to continue making that mission a reality. Traceable is building a long-term sustainable company and our team has achieved incredible milestones recently — including a 300% YoY growth. This investment will propel our next growth phase and empower our team to supercharge product innovation. Congratulations to the Traceable team for all your hard work and let’s keep the momentum going! A big thank you to our investors which include Citi Ventures, IVP, Geodesic Capital and Unusual Ventures, for believing in our mission.

Abnormal Security is on a journey to “understand humans better than humans.” This was the goal for cofounders Evan Reiser and Sanjay Jeyakumar when they first created Abnormal in 2018, which now protects almost one-fifth of the Fortune 500. In a world where most successful social engineering and phishing attacks exploit email as a channel, the cofounders saw an opportunity to apply their tech to email security. Managing Director Stephen Ward recognized the team’s potential from their first meeting, “I wanted to show the scale of my commitment… so I jumped on a 6 a.m. flight from New Jersey to San Francisco and came in person. We were supposed to speak for an hour, but we spent three hours on the whiteboard working on the product roadmap.” Reiser admired Ward's chutzpah, he says. “It means a lot when someone is willing to make a six-hour trip to come and shake your hand.” But the Abnormal team isn't just focused on cybersecurity: “When your core focus is human behavior, the opportunity snowballs with the more platforms you protect. We’re just getting started. The best from Abnormal is yet to come.” Find out more about how Abnormal Security is working to protect humans with AI: https://lnkd.in/e7CGtMCs #startup #ScaleUp #founder
