AIR Raises $50M to Secure AI Agents, Skills and MCP Servers
AIR’s researchers started with something that looked harmless: a useful AI skill. They placed it inside a respected open-source ecosystem, where it inherited the credibility of roughly 37,000 GitHub stars, promoted it to ordinary users, and watched security scanners approve it. People installed it. Eventually, AIR says the experiment reached more than 26,000 AI agents. […]
Apate.AI Raises $8.15M to Scale AI Scam Prevention Globally
Somewhere inside a scam operation, a fraudster can spend two hours persuading a victim to hand over money. For Apate.AI, the useful part is that the “victim” may never have existed. The Sydney-born company has built thousands of conversational AI agents designed to behave like believable scam targets. They answer calls and messages, keep fraudsters […]
Prevalent AI Raises $22M to Build Trusted Context for Enterprise AI
Prevalent AI is building around a problem that becomes more dangerous as AI gains more autonomy inside large organizations: fragmented data can turn a fast decision into a wrong one. The London company continuously cleans, connects, and contextualizes information from across complex enterprise systems into a sovereign knowledge graph, giving both human teams and AI […]
Mindgard Raises $30M for Attacker-Aligned AI Security
Mindgard began with the conclusion that traditional application security was looking at the wrong kind of problem. Research led by Dr. Peter Garraghan at Lancaster University had been examining AI security for more than a decadebefore Mindgard was founded in 2022. The challenge was increasingly clear: AI systems could behave probabilistically and opaquely, introducing exploitable […]
Team8 Raises $365M to Back AI-Native Enterprise Startups
AI has lowered the cost of building sophisticated software. A small team can now use frontier models to create in weeks what once demanded years of engineering. For venture firm Team8, that abundance creates a different scarcity: if competitors can access much of the same intelligence, the harder question is what remains valuable after the […]
Cytix Raises $7M as AI Coding Turns Every Software Change Into a Security Decision
Years before AI coding agents began accelerating software development, security already had a timing problem. Cytix co-founder Thomas Ballin once worked inside a large bank where a software change could move through developers, project managers, and security reviews before reaching a penetration-testing team. The process was thorough, but it belonged to a world where code […]
OpenAI’s GPT-5.6-Cyber Turns Access Into a Security Feature
Cybersecurity is starting to challenge that assumption. As advanced models become better at finding vulnerabilities and assisting with complex security research, the question is increasingly about capability and control: who should be allowed to use the most powerful cyber models, under what conditions, and with what safeguards? OpenAI is addressing that problem with GPT-5.6-Cyber, a […]
The Quiet Reason AI Might Make You Less Safe, Not More, and the $60M Bet to Reverse It
A cybersecurity startup called Corma launched this week with $60 million from Sequoia Capital and a single, unsettling claim: the same AI making your company faster is arming your attackers faster than it’s arming your defenders. They call the widening space between the two the “Defensive Gap,” and closing it may be one of the […]
OpenAI Pauses Some Astra Work Over Critical Cyber Risk
OpenAI has run into a rare problem with its next-generation model: Astra may be advancing faster than the security controls built around it. Internal evaluations showed significant gains in agentic coding and cybersecurity, pushing OpenAI to pause some work involving the unreleased model while stronger safeguards are put in place. The key concern is unusually […]
Horizon3 Raises $250M at $2B Valuation for AI Cybersecurity
Security teams can find thousands of vulnerabilities across an enterprise network. The harder problem is knowing which ones attackers can actually exploit—and whether the fix worked. Horizon3 has raised an oversubscribed $250 million Series E at a valuation above $2 billion, more than tripling its $650 million Series D valuation in just over a year. […]
Bloom Security Raises $20M to Secure AI-Native Endpoints
Employee laptops are no longer running only approved business software. AI agents, MCP servers, browser extensions and code packages can now access company systems without appearing in traditional endpoint inventories. Tel Aviv-based Bloom Security has emerged from stealth with a $20 million Seed round, co-led by Glilot Capital Partners and Ten Eleven Ventures. Okta Ventures […]
Inforcer Raises $50M to Secure Microsoft 365 for SMBs
Small businesses are adopting AI faster than many can manage the security risks that follow. London-based Inforcer has raised a $50 million Series C led by Insight Partners. Existing investors Dawn Capital and Meritech Capital remain backers. Founded by Jamie Daum, Richard Thompson and William Connor, Inforcer helps managed service providers manage Microsoft 365 security […]
