Canvas is one vendor. Your SaaS risk isn't. Prepare for next time...
A new fixed-scope assessment of your Canvas exposure and the plan behind it.

The Canvas breach got your attention. The lesson isn't really about Canvas. Every SaaS platform your institution runs, your LMS, your SIS, your payment and research tools, carries the same accumulated risk Canvas did. Developer keys, third-party integrations, webhook subscriptions, and federated SSO grants, authorized over the years and rarely reviewed since. Canvas didn't create that exposure. It just made one instance of it impossible to ignore.

ProCircular has opened the Canvas After-Action Assessment, a new, fixed-scope, time-bound engagement built alongside a Big Ten university in response to the incident in real time. It reconstructs what data actually flowed through Canvas at your institution, which notification obligations apply, and what a clear 90-day plan looks like. Six work streams, findings mapped to NIST CSF 2.0 and HECVAT 4.0, deliverables your auditors and insurance carrier can use without translation.

You don't have to be a ProCircular client to engage us, nor do you have to be on the ShinyHunters list of affected schools. You only have to recognize that if this happened with Canvas, the rest of your SaaS stack deserves the same scrutiny.

#1 in the Nation. That's our guy!

Congratulations to Bradley Greer, SOC Analyst II at ProCircular, for earning the top spot in the National Cyber League Spring 2026 Individual CTF Competition, in the highly competitive experienced bracket.

This kind of result doesn't happen by accident. It's the product of relentless curiosity, deep technical discipline, and commitment to continuous growth.

Bradley, we're thrilled for you and so proud. The work you put in every day shows, and now the whole country knows it.

Heya Friends - I don't do this often, but you REALLY need to check out our Mythos Webinar at 2:00pm. This is an area you need to understand if you're working with ProCircular or me.

Anthropic recently announced that its Claude Mythos AI model found major software vulnerabilities, some undetected for decades. In response, they launched Project Glasswing—a $100M security coalition with tech giants and industry leaders. The mission: fix critical issues before attackers exploit them. But recent analysis shows only one confirmed CVE so far (a 17-year-old FreeBSD flaw). Some experts question how much is a new discovery vs. a headline.

Here's a pretty good (but slightly exciting) YouTube on some of the future we may see:

A public report is coming in July. Meanwhile, smaller AI models can already reproduce some findings, raising questions about the real impact. For most security teams in mid-market organizations, the real challenge is what to do next. With a mountain of remediation and AI projects run amok internally, it's a lot to get your arms around for even the most seasoned pro.

Our own Jim Sherlock, V.P. of AI & Cyber Research, will unpack all of this in detail, answer your questions, and offer insights on how to make sense of this new world.

What do budget cuts to federal cyber support really mean for your security program? Join Alan Shimmel and our CEO to unpack how reduced funding changes federal response and what mid-market leaders should do next.
https://t.co/QGJI9c20YN

[ProCircular @procircular]

If you’re responsible for cyber at a hospital, university, or manufacturer, you’ve already felt it: the federal support system we all relied on is shrinking. FBI cyber agents are being reassigned, CISA’s budget was cut $490m and MS-ISAC is now behind a paywall. We’re not waiting around for that to change. ProCircular is here to help everyone we can, but I’d love to see these agencies get the funding they need, because this fight takes all of us. I sat down with @IT Brew to explain why.

Our threat intel team found my genome on the dark web.

Our team analyzed the 23andMe breach data—6.9 million genetic profiles, permanently compromised—there I was. Disease markers. Family lineage. Chromosome-level detail.

You can get a new credit card. You can't get a new genome.

23andMe filed for bankruptcy over this breach. The attack? Credential stuffing. Reused passwords. No nation-state sophistication required.

The fundamentals would have stopped it. They're not glamorous. But they work, and there's a lot to be learned here.

I wrote about what we found and what it means:
