Horizon3 hits $2 billion valuation with $250M Series E as AI threats escalate

Published

on

Cybersecurity startup Horizon3 has raised a $250 million Series E at a $2 billion valuation, more than tripling its valuation in 14 months. The San Francisco-based firm drew backing from returning investors NightDragon and NEA.

The funding arrives as two major AI research labs disclosed last week that their models had breached systems outside their intended scope. Horizon3, which has spent six years building AI specifically designed to probe networks for vulnerabilities in a controlled, authorized manner, is riding growing enterprise demand. With AI-driven attacks accelerating, enterprises are rushing to stress-test their defenses at scale, a gap that traditional security vendors have largely left unfilled.

Matt Hartley, the company’s chief revenue officer, said that its NodeZero platform has two core strengths: It can test live systems without shutting down operations, a capability other AI-powered tools have struggled to deliver reliably, and it scans an entire infrastructure continuously rather than once a year, examining the full network rather than just 2-3%.

The company approached $100 million in annual recurring revenue last year with 120% year-over-year growth,and expects to accelerate growth this year, Hartley said.

AI tools have made it easier for attackers to develop new exploits quickly, forcing security teams to handle threats faster than they can fix them. Horizon3 spent roughly $100 million in R&D building automated systems designed to stay predictable and controllable, Hartley said. That’s significant given recent breaches at AI labs, which raised questions about whether any AI system can truly remain contained.

“It’s also making people a lot more careful about how they deploy AI,” Hartley said. “We’re getting a lot of questions today around: can you detect AI? Of course we can. But I think a lot of organizations that rushed to deploy AI across the enterprise are now thinking twice about the ramifications of those deployments; what if my own security team gets too aggressive, could there be unintended consequences? So a lot of organizations are moving into what I’d call a bold new world, which is exactly why you need consistent, predictable testing from a company like Horizon3, to know how to strengthen your own defenses against real-world exploits.”

In a statement, Horizon3 has run 310,000 production security tests with zero disruptions, establishing what it calls ‘AI Hackers’, fully autonomous penetration testing.

The real competition isn’t other software vendors; it’s the existing model, according to Hartley. Most companies hire human security firms to run annual tests and those won’t disappear, he continued. What’s shifting is what clients demand after signing up: Instead of sampling 5% of infrastructure once yearly, they now want to scan everything monthly or weekly, tracking whether they’re actually getting safer.

Horizon3’s founders, Snehal Antani and Anthony Pelletier, met while serving at Joint Special Operations Command, where they saw firsthand how resource constraints made continuous security testing difficult. They founded Horizon3 to automate those repetitive assessments.

With the funding, Horizon3 is expanding internationally,including new offices in Amsterdam (in June 2026), Australia, and Singapore, while building a partner network and maintaining substantial R&D spending.  

Strategic investors now include Singapore’s EDBI, defense contractor SAIC, and Qualcomm, signaling that the vulnerability they’re addressing extends well beyond any single sector.

Horizon3 has roughly 7,200 to 7,300 customers, ranging from managed service providers serving small businesses to Fortune 10 enterprises. The company claims an addressable market of tens of billions of dollars, a figure that aligns with industry estimates of the broader cybersecurity market, valued at $271.9 billion in 2025 and projected to reach $663.2 billion by 2033, according to Grand View Research.

Frequently asked questions (FAQs)

Are AI TOPS figures directly comparable between compact workstations?

No. Vendors may calculate TOPS differently, so the largest figure does not always identify the fastest computer. Application support, usable memory, model compatibility, and independent benchmark results provide a more useful comparison.

When is ECC memory worth paying for?

ECC memory can be valuable for long calculations and production work where an error could corrupt a project or invalidate the results. Most general users and creators will benefit more from additional memory capacity or better graphics.

What does ISV certification mean for a workstation buyer?

ISV certification means a particular hardware and driver combination has been validated for professional software. It can reduce compatibility and support problems with CAD, engineering, and other specialized applications. Buyers should confirm that their intended configuration supports the software they use.

Why Investors See More Payoff in Microsoft’s AI Spending Than Meta’s

Published

on

Microsoft shares rose 15.5% on July 30, while Meta fell 8%, giving investors two sharply different ways to assess Big Tech’s AI infrastructure boom. Microsoft paired heavy spending with faster Azure growth, rising Copilot adoption and a larger commercial backlog. Meta’s advertising business grew strongly, but expenses climbed and free cash flow dropped.

Microsoft is not spending cautiously. It reported $41 billion in quarterly capital expenditures, while Meta expects total 2026 capital expenditures of $130 billion to $145 billion. The periods and accounting details differ, so the figures are not directly comparable. Investors responded more favorably to Microsoft because its results showed clearer links between infrastructure investment, cloud consumption, software subscriptions and contracted demand.

The July 30 market reaction followed Microsoft’s fiscal fourth-quarter results. Quarterly revenue and operating income both rose 18%. Azure revenue increased 43%, while full-year Azure revenue exceeded $100 billion for the first time.

Microsoft also reported more than 30 million paid Microsoft 365 Copilot seats, with net additions more than doubling from the previous quarter. Its commercial remaining performance obligation — contracted revenue not yet recognized — rose 84% to $678 billion. About 30% is expected to be recognized within 12 months.

Those disclosures give investors several measurable demand signals. Customers are buying Copilot licenses, consuming Azure services and making multiyear commitments. Microsoft also operates several commercial platforms that can use the same infrastructure, including Azure, Microsoft 365 and GitHub.

The buildout still carries financial pressure. Microsoft reported $19.6 billion in quarterly free cash flow as capital expenditures increased. Its company gross margin percentage fell year over year, driven partly by the sales mix shifting toward Azure and continued AI infrastructure investment. Microsoft forecasts Azure growth of approximately 45% in constant currency for its next quarter.

Vendor growth does not guarantee that each deployment will produce an acceptable return. Because AI agent cloud costs can vary sharply between similar workflows, IT teams need workload-level controls, adoption data and measurable operational results before expanding Azure AI or Copilot contracts.

Meta’s AI returns remain harder to separate

Meta raised the lower end of its 2026 capital-expenditure forecast from $125 billion to $130 billion, leaving the upper end at $145 billion. The forecast includes principal payments on finance leases. Quarterly free cash flow fell to $784 million from $8.55 billion a year earlier.

Meta’s core business remained strong. According to Meta’s second-quarter results, revenue increased 28% to $60.8 billion. Ad impressions rose 14%, while average ad prices increased 12%.

Meta says AI is improving its core business and supporting new products, but it does not report AI-attributable revenue separately. Total costs and expenses rose 55%, while operating income declined 8%. The quarter included $2.4 billion in legal charges and $1.18 billion in severance expenses, so AI investment alone did not cause the decline.

Meta expects its infrastructure to support larger models, personal agents and future enterprise products. It is also reportedly considering whether to sell access to excess AI compute, but it has not announced a commercial service, pricing, availability or financial targets.

Investors are applying a similar test elsewhere. Google recently raised its 2026 capital-spending forecast to as much as $205 billion as cloud demand accelerated. Microsoft currently provides stronger evidence of revenue growth and contracted demand, while Meta’s newer AI businesses remain financially less visible.

Cryogenic Firefighting Robot Could Fight Wildfires

Published

on

Yiannis Levendis, a professor of mechanical and industrial engineering at Northeastern University, has developed a prototype firefighting robot that sprays liquid nitrogen onto flames to extinguish them quickly. The project grew from a laboratory experiment in 2008, when Levendis was testing shredded tire rubber as a possible alternative fuel.

“Liquid nitrogen, when thrown on fire, quickly evaporates and expands into gas almost 1,000 percent,” Levendis said. “That suffocates the fire and creates a cooling effect on the fuel.”

He said the flames were extinguished almost immediately, prompting him to explore whether the same approach could be adapted for wildfire response. Northeastern Global News reported that the robot is designed to suppress small fires and hotspots before they grow into major wildfires.

How the robot works

The prototype, built with Northeastern students Hayden Hishmeh and Aobo Liu, resembles a compact all-terrain vehicle with caterpillar tracks, a liquid nitrogen tank and a spray hose. It can be operated remotely or potentially autonomously, allowing it to move into areas that may be too dangerous for firefighters.

Unlike many wildfire retardants, liquid nitrogen does not leave behind chemical residue. As it rapidly turns into gas, it cools burning vegetation while reducing the oxygen available for combustion. The robot is currently being tested on controlled fires using forest fuels common in wildfire-prone areas of the western United States.

Tom Ryden, executive director of MassRobotics, said the approach could appeal to firefighting agencies or industry partners.

“A perfect use for robots is to send them into dangerous spots,” Ryden said, according to Northeastern Global News. “Even if we lose a robot, it’s just the cost of the machine that’s lost, not a person.”

Levendis also believes the cryogenic system could eventually be adapted for much larger firefighting vehicles. “I believe it can be converted to vehicles as large as firetrucks,” he said. “We are fairly close.”

More must-read AI coverage

Field deployment still faces major hurdles

The technology is still in the prototype stage, and significant engineering challenges remain before liquid-nitrogen firefighting robots could be deployed in active wildfire operations. Cryogenic storage, transportation logistics and the amount of nitrogen required for sustained firefighting would all need to be addressed.

Even so, the project points toward a different strategy for wildfire response: using robots to attack small ignition points quickly, especially in terrain that is too risky for human crews. If that approach proves practical, it could become a useful complement to existing wildfire suppression methods rather than a replacement.
