Orgs need to be able to use agents, MCPs, and LLMs in ways that don't lead to unexpected actions and undesirable outcomes. The OWASP Agent Security Regression Harness project is an approach for defining customizable scenarios and testing whether those systems fail against known security threats. Mert Saltimaz talks about the background of the project, how orgs can use it as they bring more LLMs into their environment, and how the project intends to grow. Importantly, we also talk about the security controls and designs that orgs can build around the systems and data that models interact with in addition to evaluating the security of the agents and agent harnesses themselves.

What do we really know about "AI Network Protocols"? Network security is about to get popular all over again.

Generative AI caused a disruptive explosion across all of tech and every company's roadmap. The move from chatbots to AI agents doubled down on that disruption. Now agents need to talk to each other?

Boom: we have MCP. A2A. Universal Commerce Protocol. General purpose and specialized protocols for agent communication. What does this look like from the network perspective, though? O'Shea Bowen joins us to answer this question, and he thinks the results are interesting enough to spark a resurgence of interest in network security tooling.

Jeremiah Grossman on why we've been measuring cyber risk wrong for 20 years

After decades helping shape modern web security, and building companies that were ultimately acquired by Synopsys and Tenable, Jeremiah Grossman believes cybersecurity has arrived at an inflection point. His argument is a provocative one: for years, the industry has optimized around the wrong metrics. His latest venture, Root Evidence, aims to help security teams identify which risks are most likely to cause meaningful business loss, and he has the evidence - real-world breach data, cyber insurance claims, digital forensics intelligence, attack surface intelligence, and observed attacker behavior - to back it up.

America has lived through technological and economic upheaval before. Farm workers moved to factories. Factory workers moved into services. New industries replaced old ones. Productivity rose. Living standards improved. But are we ready for the greatest disruption in American history?

Ben Gilliland, author of the upcoming book Breaking the Compact, joins Business Security Weekly to discuss why business leaders need to be prepared for the upcoming AI disruption. The impact of AI, which has not fully materialized, goes far beyond security and job displacement. It will impact our economy, our privacy, and our way of life. The closest recent warning is the "China shock," the period of rapidly increasing import competition that followed China's integration into the global trading system. AI will dwarf that. Ben will discuss the human advantage and how we can prepare now.

Appsec often frames usability and security as at odds with each other. Apple's software has famously emphasized the importance of usability while also creating a solid security foundation. Patrick Wardle talks about how he's seen malware shift from Windows to macOS, how Apple's aggressive stance on deprecation benefits security, and the areas of the OS where he still sees plenty of opportunity for more security research. We discuss how developers make defensible design choices, why privacy needs security, and some security principles that any app developer should keep in mind regardless of their programming language or operating system.

Why AI Security Is Becoming an Execution Problem, Not Just a Governance Problem

As enterprises move from AI experimentation to adoption at scale, security leaders are under pressure to enable innovation without introducing unmanaged risk. The challenge is no longer whether organizations should pursue AI, but how they can govern it, secure it, and operationalize it in ways that stand up to real-world business and threat conditions.

In this conversation, Keith Hollender discusses what Arcova is seeing across enterprise environments as organizations work to connect cybersecurity, AI governance, resilience, and broader transformation priorities. He explores where companies are getting stuck, why traditional siloed approaches are falling short, and what it takes to move from strategy decks to secure execution.

Keith also shares how Arcova's practitioner-led, relationship-driven model helps organizations turn complexity into clarity by embedding with client teams, solving urgent problems hands-on, and building capabilities designed to last. The conversation also covers Arcova's continued growth, including expansion into the Middle East, and what global demand signals reveal about the next phase of cybersecurity and AI consulting.

This one sent some shockwaves through the CMMC community, particularly the hundreds or thousands of folks gearing up to assist with the validation that phase 2 aimed to provide. The TL;DR - defense contractors have been required to comply with CMMC controls for years, but self-attestation means that many probably haven't been meeting the requirements. Perhaps, rather than have tons of defense contractors fail the test, they just suspended the requirement for the test itself.

I think Howard Holton nails it here when he says:

"100,000 defense contractors needed third-party assessments. Roughly 100 authorized assessors exist. That's 1,000 assessments each, with the deadline in November."

PCI already created a model that works for a scenario like this. If you're small, you self-assess. If you're big enough, an independent auditor comes to check you out once a year. I'm sure they were probably aware of this and chose not to go down that path for some reasons. I'm not aware of those reasons.

What this means:

• Phase II is paused
• Phase I self-assessments still in place (note, however, that phase II existed, because self-attestation didn't work)
• NIST SP 800-171 Rev 2 and DFARS 252.204-7012 compliance still required
• 60-day review aims to reform CMMC
• DoW opened an RFI for industry perspectives on what they should do
• CMMC characterized as a "compliance burden" and "red tape"
• False Claims Act and DOJ's cyber-fraud enforcement are still on the table

• Administrator of the Small Business Administration, Kelly Loeffler's post
• A useful LinkedIn post that breaks down a lot of what this really means (and doesn't)
