Today, Anthropic released Opus 4.7. We were lucky enough to have early access.
We have been working with the model for a while – evaluating it to understand how it actually behaves in real offensive workflows.

What is AI pentesting? How is it different from PTaaS? What should you look for in an AI pentesting solution?
We hear these questions a lot, and we created a buyer's guide to answer them.

Systems that decide what to do next > traditional tools
That’s the advantage of agentic AI: discovery, prioritization, and broader coverage.
Our Head of AI, Albert Ziegler, discusses how systems don’t just run tests; they choose what to test next in Cyber Security Tribe: https://bit.ly/4lZzo0y
The last Patch Tuesday released the embargo on some _very_ juicy RCEs. Thanks to Microsoft's sec team for the disclosure, it's been a smooth and mature coordination process.
That’s a wrap on #RSAC!
We came, we saw, we showed the power of continuous exploit-validated testing and what it unlocks for modern security operations. 🏹
Thanks to everyone who stopped by our booth, tuned into our fireside chat, and booked a meeting this week. 🙌
XBOW is now valued at $1B+ following a $120M round led by DFJ Growth and NorthZone VC.
Security can’t stay reactive when attacks are becoming autonomous.
Our CEO discusses how this is just the beginning in @bloomberg.com: https://bloom.bg/4bvMTSf
🏁 #RSAC 2026 starts now.
If you’re on the show floor, kick things off with XBOW!
Join us at Booth #1843 and let our team show you the next revolution in cybersecurity: AI-powered continuous offense.
I joined Xbow in January because I was intrigued by the idea of continuous pentesting and using AI for something meaningful.
Today it seems like I was right to be intrigued. XBOW is a unicorn 🦄!
Most of the XBOW founders, at our first offsite in 2024.
Almost all of the XBOW team, at our most recent offsite in 2026.
XBOW joined the unicorn club today!
When we founded this, we had no idea whether using AI for pentesting was even possible. Back then, it honestly wasn't! So hearing a customer gasp and say "it's acting like a nation-state attacker" has made 2 years of work feel worth it.

Not directly from rocks. The structures are formed biologically from Ca ions dissolved in the seawater (look up “biomineralization”). Presumably chalk and limestone are good sources for the calcium to get into the seawater in the first place, but I’m guessing at this point.

Huge appreciation to the Seznam team!
On their first demo, XBOW identified a critical vulnerability with zero access and zero prep, just autonomous offensive security doing real work for a real customer.
It’s the kind of partnership that proves what matters.
