Project Glasswing Strengthens Key Platforms, Leaves Broad Exposure Untouched

Thursday was a brutal day for cybersecurity stocks amid a broader software selloff and continued uncertainty around whether the ceasefire with Iran will hold.

Just three of the 20 largest public cybersecurity companies recorded stock price gains between 2:30 p.m. ET Tuesday and early Thursday afternoon. One was Trend Micro, and the other two were the only pure play cybersecurity companies serving as launch partners for Project Glasswing: Palo Alto Networks and CrowdStrike.
“Project Glasswing will harden a handful of platforms,” former NSA Cyber Director Rob Joyce wrote on LinkedIn Wednesday. “That is good news for us all because we all rely on their products. The bad news is the rest of the internet. The mountain of technical debt sitting in everything from industrial controllers to municipal systems to the average enterprise app stack is not getting a Glasswing review.”
How Project Glasswing Could Widen Cyber Market Divide
Initiatives such as Project Glasswing could exacerbate the growing gap between the cyber “haves” and the cyber “have nots,” with nine of the 11 public cyber vendors with valuations exceeding $14.9 billion – including Palo and CrowdStrike – seeing their stock prices rise in 2025. In contrast, all 12 security vendors with valuations between $1.1 and $14.9 billion saw their stock price fall last year (see: Why Claude Mythos Shifts Focus From Finding to Fixing Bugs).
The cybersecurity titans with access to Claude Mythos Preview have already detailed how they plan to use the cutting-edge AI model to strengthen their own defenses. CrowdStrike paired Mythos Preview with native real-world telemetry, endpoint visibility and enforcement controls and made it operationally meaningful by tapping into existing security data, governance and runtime protections.
Palo Alto Networks, meanwhile, used Claude Mythos Preview to spot complex vulnerabilities that prior-generation models missed entirely. Hybrid security players serving as Project Glasswing launch partners also put Mythos to work, with AWS applying it to critical internal codebases to further harden code and Microsoft using it to find issues across a larger surface area earlier in the development life cycle.
“It’s clear that these models need to be in the hands of open-source owners and defenders everywhere to find and fix these vulnerabilities before attackers get access,” Palo Alto Networks Chief Product and Technology Officer Lee Klarich said in a statement.
Launch partners gain access to capabilities before the broader market, allowing them to refine integrations, build differentiated offerings and shape customer expectations, said IDC Group Vice President Frank Dickson. He said this creates a compounding advantage in which early adopters not only deploy faster but also learn faster, widening the gap between them and the market over time.
“I’ve never seen innovation happen at this rate,” Dickson told ISMG. “It’s almost happening at an exponential scale. So, there’s always first-mover advantages. I think first-mover advantages in this environment are accentuated.”
What Mythos Preview Means for Vulnerability Management
Cato Networks CEO Shlomo Kramer said the only way of making the prevention, detection and remediation cycle faster is by training agentic researchers ahead of the attackers. Models such as Mythos Preview can deliver algorithms and content to a vendor’s underlying security platform based on the same intelligence the agentic attacker has, Kramer said.
Cybersecurity vendors serving sophisticated enterprise buyers including Palo Alto Networks or CrowdStrike must remain at the forefront of innovation as their customers demand advanced capabilities, Dickson said. In contrast, Dickson said vendors targeting SMB or consumer markets may prioritize usability and cost-effectiveness over cutting-edge features, allowing for a different pace of adoption.
“This foundation [Project Glasswing] in this approach needs to be fairly egalitarian, and they need to allow others to join,” Dickson said. “Because if they don’t, then at some point, antitrust issues start raising their ugly heads.”
Kramer said Cato Networks has a strong relationship with Anthropic, is in constant communication with the company and will get early access to Claude Mythos Preview as well. Kramer expects Project Glasswing participants will share all the information they’ve obtained and make it public as companies do with CVEs.
But at least for now, the rest of the cybersecurity vendor community won’t have the same advantage. 17 of the 18 cybersecurity vendors that aren’t part of Project Glasswing experienced stock price declines since Tuesday, with four recording stock price drops of at least 12%.
One of the big losers was identity security provider Okta, while the other three are all pure-play vulnerability management firms: Qualys, Rapid7 and Tenable. Stock prices for the three companies dropped in both 2024 and 2025 as growth in the rapidly maturing $2.3 billion market slows and the technology becomes commoditized.
“This will break the vulnerability management playbook,” Forrester wrote Wednesday. “Glasswing sets the stage for a potential new vulnerability discovery and cataloging system that’s closed and controlled by approved partners and software maintainers. This will disrupt the way signature-based network and application vulnerability scanners fundamentally operate, giving way to AI-based tools.”
Vulnerability and exposure management platforms encompass a wide range of functions including asset discovery, risk assessment and patch deployment. Dickson said Claude Mythos Preview enhances one aspect of this process but doesn’t replace the broader ecosystem.
“It’s a wonderful tool to be able to evaluate software for vulnerabilities, but let’s not overstate it,” Dickson said. “You’ve got a piece, but it’s not the whole banana split.”
