Rubrik is a top-tier company in a top-tier sector, one of the first to tackle agentic AI security, and well on its way to becoming a $50B cybersecurity leader this decade. Q2 revenue rose 38% to $427.3M versus $396.3M expected, subscription ARR grew 33% to $1.66B and cloud ARR 39%, with a 15% free-cash-flow margin. Cybersecurity's TAM keeps expanding, with giants like Palo Alto Networks, Cloudflare and CrowdStrike still growing double digits. x.com 

Rubrik looks more interesting than CrowdStrike here because agentic AI creates an even bigger cybersecurity tailwind for it. Identity and data security could be two of agentic AI's biggest cybersecurity beneficiaries. Rubrik is a young IPO flagging after breaking out of a 14-month base, growing 30%+ at a valuation near CrowdStrike's, and technically resembles Arm when it broke its IPO base around the $170s. x.com 

Rubrik is in a dangerous place, one deceleration away from growth in the 20s while still sub-scale. Palantir is a better company at a much better multiple and is accelerating while sustaining triple-digit growth. Rubrik would be worth a solid bet in the $60s or $70s, but on current fundamentals it shouldn't be more than a 5% position. x.com 

Rubrik's high switching costs and emerging AI-security demand underpin growth that looks attractively valued. At 12.9x forward EV/sales, it trades below the cybersecurity peer median relative to expected revenue growth. Subscription ARR grew 32.6% YoY and net dollar retention reached 119%. Agentic AI security adoption remains early; non-GAAP operating margin hit 7.8%, though GAAP net income remains negative partly due to stock-based compensation. x.com 

Rubrik is a decent way to own cybersecurity at about 9x next-twelve-month revenue, while CrowdStrike, Cloudflare and Palo Alto Networks valuations look ridiculous. It still needs to improve margins and reduce dilution. x.com 

Rubrik is too expensive now against a $70-80 valuation, even though its very strong platform drives nearly 40% growth that can continue for many years as a cybersecurity and data-recovery play. x.com 

Rubrik has become part of the cybersecurity infrastructure layer in the agentic AI era, agnostic to models, chips and clouds. Strong CrowdStrike and Okta reports should mean a substantial beat and raise, and maybe a rerating. If that doesn't come, it would raise questions, as security starts sorting into winners and not-winners. x.com  x.com 

Rubrik's new partnership with MEDITECH extends its cyber resilience platform into a leading electronic health record system, and the stock has moved back above its 30-week average. Rubrik Security Cloud will bring immutable backups, threat detection, malware containment and rapid recovery to MEDITECH Expanse in cloud and on-premises settings, cutting ransomware downtime and protecting patient care. x.com 

Being long what shrinks successful breaches beats owning Rubrik, which gets paid cleaning them up. Fixing may not stay a separate job: Astra went from 34 to 86 of 226 on FrontierCyber in one generation and Codex Security has marked 500,000 findings fixed. Recovery is harder to call, as models speed up attackers and defenders alike; no model restores a ransomed network today, as @AlokANYC's United example shows. Models could take on some restore work within five years, though how much is unclear. … Show more

Cybersecurity stocks have a powerful long-term tailwind because more AI means more complexity, more attack surface and more need for security. CrowdStrike, SentinelOne, Palo Alto Networks, Zscaler, Fortinet, Okta and Rubrik moved up strongly premarket after Anthropic CEO Dario Amodei published an essay arguing the AI industry should slow down, with Anthropic committing to give third-party evaluators permanent access to verify its safety measures. The market may be connecting those dots. x.com
