Cribl acquires Radiant Security's AI-powered SOC tech to automate security alerts

Cribl has acquired technology assets from Radiant Security's AI-based security operations centre solution. The acquisition includes intellectual property for autonomously qualifying, analysing, and processing security alerts. The deal marks Cribl's second security technology acquisition this year, following CardinalOps in July. Cribl will integrate the AI-driven SOC technology into its telemetry data platform, enabling security teams to ensure AI makes appropriate decisions based on relevant data. The platform generates custom qualification logic for each alert rather than relying on predefined playbooks, executing investigations directly from telemetry data regardless of storage location. This approach aims to improve threat detection and reduce false positives. Cribl CEO Clint Sharp said the acquisition addresses data silos in the $121 billion security market, providing security teams with comprehensive insights as AI transforms operations.

The clearest named actors are Cribl and Radiant Security. The likely spillover reaches companies, platform operators, and workers likely to absorb the operational change. Capital, competitive position, or market structure is moving around this part of the AI stack. It is being reported now because money, leverage, or competitive positioning in AI is visibly shifting. For readers, this belongs in the AI Risks and Governance lane and the AI Business and Markets topic, which means the important details are not only who announced what, but which expectations, costs, rules, or capabilities may now move around it. The useful reading is simple: Capital and competitive pressure may be shifting around this part of the AI stack. Chip interpretation What it means The factual signal is straightforward: Telemetry data company Cribl Inc. today said it has acquired technology assets from artificial intelligence security operations startup Radiant Security Inc. The purchase covers... Read this through The practical question is whether this changes incentives, costs, rules, or behavior beyond the announcement itself. Decision test Read this through budgets, workflow design, labor pressure, and business adaptation rather than through launch language alone. For anyone affected by business, the useful test is whether this changes trust, cost, rules, capability, or expected human judgment after the first attention wave passes. Why this matters The consequence is more important than the headline. These are the areas most likely to move if this reported change hardens into policy, infrastructure, or default expectation. Impact card Business impact. This can change budgets, rollout timing, or vendor leverage faster than the headline suggests. The practical business question is whether it shifts cost, speed, or bargaining power. Impact card Human impact. People may not feel the effect immediately, but the signal can still change day-to-day expectations. It matters once the behavior becomes normal, not just once it gets announced. Impact card Governance impact. This is really about who gets to approve, delay, or shape deployment. Once release decisions move closer to institutions, technical change becomes a power question. Impact card AI ecosystem impact. This matters to the AI ecosystem if it starts to change standards, expectations, or the balance between builders, buyers, and regulators. Repetition is what turns this from news into infrastructure. Who gains / who is pressured Follow the incentives, not the announcement. * Teams that adapt early: They can convert new capability into faster workflows, lower cost, or clearer strategic positioning. * Infrastructure and platform providers: They benefit when AI usage deepens and demand moves upward through the stack. Who is pressured * Slow incumbents: They are exposed if they wait too long to translate the signal into operational change. * Roles built on repeat tasks: They feel pressure when AI starts taking over routine judgment or task execution. Multiple perspectives Trust improves when the angles are visible. Enterprise view The useful lens is whether this changes cost, workflow design, procurement logic, or execution speed inside a company. Worker view The real question is whether the change removes routine work, raises expectations, or shifts what counts as valuable human judgment. Investor view The signal matters if it changes margins, adoption speed, defensibility, or where value accumulates across the stack. What humans should do Primary action: Prepare. * Review the workflow, budget, policy, or product area this signal touches before it becomes urgent. * Decide what would trigger a real change in plan if more stories of this kind appear. * Translate the signal into one concrete preparedness step for the team rather than vague concern.

Radiant expands into Europe as demand accelerates

Radiant expands into Europe as demand accelerates. Eliane Limon Table of contents. The data residency barrier is finally gone. The demand for AI-driven SOC automation has been overwhelming. Over the past 18 months, hundreds of European security teams have requested access to Radiant, teams eager to automate alert triage, investigations, and response without compromising data residency. Today, Radiant Security, Inc. is proud to announce that the barrier has been lifted. Radiant Security is now available in the EU, using the AWS EU Frankfurt Region (eu-central-1). Radiant's EU Infrastructure is built for Sovereignty, complies with GDPR and SOC 2 Type II certification, and does not support cross-border data processing. If you're a European security team, you can finally adopt the full AI SOC platform without the legal and operational compromises, or if you're a global organization with European operations, you can: * * Standardize on a single AI SOC platform across regions * * Reduce compliance overhead by eliminating region-specific workarounds * * Give your EU teams the same automation capabilities as your US counterparts EU security teams pioneer a broader global shift. Over the past two years, North American headquartered platforms have emerged as leaders in the AI-driven SOC automation world. These platforms serve modern alternatives to traditional SIEM, SOARs, and MSSPs. But that technology has largely remained limited for European teams due to data residency constraints. With Radiant opening up the EU market, European security leaders have become the second-largest market for the SOC AI platforms. This enables security leaders across Europe to: * * Reduce the false positive rate by over +90% * * Fully automated alert investigations and response for any type of alert * * Ingest, retain, and query logs with an integrated log manager, free of charge What this means for your globally distributed team. If you've been waiting for a compliant way to bring AI automation to your SOC, or if you're just curious about how you can achieve an in-house SOC for your lean SOC team, now is the time to explore what's possible.

2025 Proved Why We Built AI SOC Before It Even Had a Name

2025 proved why Radiant Security, Inc. built AI SOC before it even had a name. For years, AI in the SOC was a romanticized idea, but no one knew when or how it would arrive. Curious SOC leaders researched AI to understand its potential. Conversations took place, but mostly overpromised and underdelivered. At Radiant, Radiant Security, Inc. has watched the market shape and mature from the firsthand perspective of category pioneers. When Radiant Security, Inc. started, clients came curious about what AI could actually do. They arrived skeptical and left impressed by the operational relief Radiant Security, Inc. delivered. Today, its clients have evolved, and so has its product. RSAC 2025 was the first time Radiant Security, Inc. didn't need to explain what this is about; instead, Radiant Security, Inc. talked capabilities, use cases, and pricing. SOC leaders now seek future-proof solutions that act as natural extensions of their team, thinking like them, understanding their evolving context, and fitting in seamlessly. 2025 was the year AI matured enough to meet that need. Real product-market fit created an official new category: the AI SOC platform. More growth, more competition. This year, Radiant grew significantly, and so did the number of "AI SOC Platforms." Radiant Security, Inc. see this as market validation. When SACR published its 2025 AI SOC landscape report, Radiant Security, Inc. celebrated twice: First, Radiant was recognized as having the 'most unique value proposition' and nominated as a key AI SOC vendor amongst dozens of players. As pioneers, Radiant Security, Inc. maintained strong differentiation as new players entered. Second, close to a hundred vendors made the "AI SOC" list- that's a category win. According to SACR, AI-driven SOC platforms emerged as a top strategic priority for CISOs in 2025. Radiant wrapped: 2025 product milestones. AI triage with the broadest coverage Radiant Security, Inc. launched the most advanced version of its Agentic AI SOC platform, automating triage, investigation, and remediation for 100% of alerts, regardless of source, complexity, or novelty. No rigid playbooks. Radiant adapts to any alert just in time, exactly like your best analyst would. Radiant Security, Inc. surpassed 100+ integrations Radiant Security, Inc. became the 'yes man' for every integration request. Today, Radiant Security, Inc. offer the broadest integration scope among AI SOC platforms, making Radiant Security, Inc. the only ones who can truly deliver 100% coverage. Integrated log management for unlimited ingestion and retention Radiant Security, Inc. kept hearing: 'SIEM pricing forces us to choose which logs we can afford to keep.' This wasn't just a budget issue; it was crippling AI investigations. Its AI can only connect the dots it can see. Its integrated log management lets you ingest everything without the pay-per-volume trap. Now its AI stitches together data across every source, uncovering connections incomplete logs would've missed. Some clients replaced their legacy SIEM entirely. Looking ahead. I've spent nearly 25 years in this industry. Through it all, one thing never changed: SOC teams were always underwater. That's what drove my co-founder Barry Steinman, and me to start Radiant four years ago. 2025 proved that SOC teams don't need more rules, bigger budgets, or AI with conditions and exceptions. Radiant Security, Inc. built Radiant to integrate seamlessly with any stack and workflow, delivering AI triage for your SOC as it exists today, while autonomously adapting to new threats. I'm grateful to be building this alongside an incredible team, customers, and partners. It really is the best time to be doing this work.
