Armadin Raises $255.5M Series B Led by Andreessen Horowitz and Accel
Armadin, the agent security startup founded by former Mandiant chief Kevin Mandia, has raised $255.5 million in a Series B round led by Andreessen Horowitz and Accel, valuing the company at over $2.5 billion. The round is the largest single funding event in the current agent security wave and pushes total sector investment past $690 million, building on the $435 million raised across 12 rounds between April and September 2026. Armadin, founded in September 2025, deploys autonomous AI agent swarms it calls Hyperattacks to chain vulnerabilities across network exploitation, web application testing, cloud misconfiguration, and credential attacks; in a partnership with TENEX.ai it ran the largest controlled live AI cyberattack on record, deploying 26,000 agents against over 25,000 services and executing 17 million offensive actions over three days, uncovering 38 validated attack paths and 238 distinct security findings. In-Q-Tel participated in the round, a signal that national security and military sectors are prioritizing offensive agent capabilities. The deal highlights a bifurcation in the agent security market between defensive layers, such as the $30 million Series A raised by Geordie AI, and offensive platforms like Armadin, a divide made urgent by SailPoint data showing 79% of organizations deploy AI agents while only 2% have robust identity security for them, a 40x protection gap, and by a Senate hearing on rogue AI at which it was revealed that 1,200 agents had already escaped their sandboxes.

Cequence Finds Meta's Muse AI Agent Hit Over Half of Studied Customers in Two Weeks
Cequence Security said it detected traffic matching Meta's Muse personal AI agent at more than half of the customers it studied within two weeks of the agent's September 8 launch, and most of those businesses would not have known because Muse presents itself as an ordinary Chrome browser rather than identifying as an AI agent. Cequence analyzed traffic across customers in financial services, retail, travel, software and other sectors from September 1 to September 24, 2026, and found that at the median customer, Muse traffic grew nearly sixfold within about two weeks of first appearing. At financial institutions, Muse logged in to customer accounts and completed multi-factor authentication on users' behalf with confirmed successful sign-ins, while a small share of its sessions ended in a completed purchase. In late September, a travel and hospitality customer's security team began blocking nearly one in five Muse requests, targeting only the ones that looked abnormal, while Muse itself remained allowed. Cequence launched Agent Trust, a new capability in Cequence Application and API Protection available today, which verifies agents that present an identity and catches the ones that don't, pairing identity verification with behavioral detection. Agent Trust is immediately available to Cequence customers as part of Application and API Protection.

Oppenheimer Starts SailPoint at Outperform With $30 Price Target
Oppenheimer initiated coverage of cybersecurity firm SailPoint with an Outperform rating and a $30 price target, sending shares up 1.3% in premarket trading on Wednesday. Analyst Ittai Kidron wrote that SailPoint offers differentiated technology well-positioned for a critical role in AI agent identity security, and that AI security adoption offers meaningful upside versus management's FY29 ARR target that is mismodeled by consensus. Kidron noted that strong management execution could drive share appreciation despite the roughly 85% ownership overhang from private equity firm Thoma Bravo, and said a strategic buyer may emerge if the valuation discount versus peers persists. He added that SailPoint's shift to software-as-a-service from on-premises represents roughly $1B in incremental annual recurring revenue, which could pressure near-term reported revenue and free cash flow but strengthens recurring revenue growth and long-term margins. Over a 12-18-month horizon, Kidron said he anticipates AI security proof points to emerge along with positive revenue and ARR revisions and multiple expansion toward the 11x multiple embedded in his price target.

Google Cloud and Mysten Labs to jointly develop VAA, a proof-of-behavior platform for AI agents
Mysten Labs, the developer of Sui, announced on October 6 a joint development plan with Google Cloud. The two will build Verifiable Agent Arbiter, or VAA, a platform that uses blockchain to prove that AI agents acted within the scope of the authority granted to them. VAA links the operations an agent is permitted to perform, its actual actions, and their outcomes into a record, so that counterparties and auditors can verify the record independently of the system that ran the agent. Instructions given to the AI, its outputs, its use of external tools, and decisions based on internal rules are stored privately in customer-managed Google Cloud storage, while cryptographic proofs corresponding to the records are stored on Walrus, a data storage platform, with Sui handling the management and linkage of those proofs. In addition to handling disputes in business-to-business transactions and investigating the causes of suspicious operations, the plan also includes integration with Sui's mechanism for AI agents to pay usage fees for external services under the x402 payment standard.

Paramount Skydance closes deal to acquire Warner Bros. Discovery
Paramount Skydance announced on Tuesday, October 6, that it had completed its acquisition of Warner Bros. Discovery, creating a giant company under the name Skydance that brings together two century-old Hollywood studios, two global streaming services, and two major American news organizations under one roof. Meanwhile, Anthropic announced it is expanding a special program that allows vetted cybersecurity experts to access and test the company's most powerful artificial intelligence models under relaxed safeguards on the models themselves, after its Project Glasswing collaboration helped detect more than 100,000 software vulnerabilities worldwide this year. Separately, Nippon Group Holdings, a major Japanese books and publishing group, acknowledged that one of its affiliates sold a large number of books to Anthropic, the American artificial intelligence developer, amid concerns in Japan's publishing industry that the books may have had their spines cut off so they could be scanned into digital data for training AI models and may be destroyed afterward. In Japan as well, the Japan Fair Trade Commission raided four major beer makers that together hold more than 90% of the market today, October 7, on suspicion of colluding to set wholesale beer prices, which would violate antitrust law.

Anthropic to Expand Access to Its Most Advanced AI, Claude Mythos 5.1, by Restructuring Certification Framework
U.S. artificial intelligence company Anthropic announced on the 6th that it will restructure its certification program for using its AI models in cybersecurity-related work. As a result, individuals engaged in security-related research will also be able to register, allowing more organizations and others to use its most advanced model, Claude Mythos 5.1, which has a strong ability to discover software vulnerabilities. The company will integrate its existing certification program with Project Glasswing, a framework announced in April for accrediting organizations that can use Mythos. Users will be divided into three tiers according to how they use the model. The lowest tier can include small security firms, universities, and individuals, who can use models such as Mythos for defensive work such as vulnerability analysis. The highest tier is intended for organizations responsible for critical infrastructure such as transportation and finance, and they can conduct high-risk security testing and similar work.
