Large language models are most useful to your business when they have access to your data. But these models also overshare by default, providing need-to-know information without sophisticated access controls. But organizations that try to limit the data accessed by an LLM risk undersharing within their organization, not giving the information users need to do their jobs more efficiently.

In this episode, Sounil Yu, CTO at Knostic, explains how they address internal knowledge segmentation, offer continuous assessments, and help prevent oversharing while also identifying under-sharing opportunities. Joining him are our panelists, Ross Young, CISO-in-residence at Team8, and David Cross, CISO at Atlassian.

Knostic protects enterprises from LLM oversharing by applying need-to-know access controls to AI tools like Microsoft 365 Copilot. Get visibility into overshared data, fix risky exposures, and deploy AI confidently—without data leakage. If you’re rolling out Copilot or Glean, you need Knostic.

Unauthorized site access remains a significant security concern for organizations. But why does this issue persist, and how can it be effectively addressed?

In this episode, Rob Allen, chief product officer at ThreatLocker, discusses the core functionality of ThreatLocker's Web Control solution: blocking access to unauthorized sites without meddling with DNS servers—a common pitfall among other tools. Rob explains that the simplicity of defining where employees can and cannot access is pivotal. This approach not only helps keep users away from malicious sites but also steers them clear of non-productive ones, thereby enhancing resource allocation. Rob is joined by our panelists, TC Niedzialkowski, Head of IT & Security at Opendoor, and Sasha Pereira, CISO, WASH.

Linux is the backbone of critical infrastructure, yet it often flies under the radar when it comes to endpoint monitoring. From legacy servers to embedded systems, Linux devices are frequently unprotected, either due to operational risk, overlooked assets, or the false assumption that Linux is “secure by default.”

In this episode, Craig Rowland, founder and CEO of Sandfly Security, introduces an agentless approach to EDR purpose-built for Linux systems. By operating over SSH and running rapid, randomized checks without traditional kernel hooks, Sandfly can monitor unprotected Linux endpoints, detect fileless and dormant attacks, and uncover SSH key-based lateral movement—all without tipping over sensitive systems. Joining Craig are Jerich Beason, CISO at WM, and Steve Zalewski, co-host of Defense in Depth, dive into where this solution fits in the broader Linux security conversation and why it might be the missing piece for OT and critical infrastructure teams.

Sandfly delivers agentless Linux EDR that deploys instantly across all distributions and architectures - from cloud servers to embedded devices and legacy systems. Our platform detects evasive threats, monitors SSH keys, and identifies system drift without performance impacts. Comprehensive Linux security without the endpoint agent risk.

For years, patch management has been treated as a solved problem—until reality strikes. Outdated applications, portable executables, patch conflicts, and shadow software leave organizations unknowingly exposed. The tools may exist, but the process often breaks down.

In this episode, Rob Allen, chief product officer at ThreatLocker, discusses why their new patch management solution goes beyond legacy approaches. With built-in patch packaging, pre-deployment testing, and granular control, the platform helps teams navigate complex environments while keeping rollback, risk tolerance, and deny-by-default strategies in play. Joining him are Mike Woods, vp of cybersecurity at GE Vernova, and Steve Zalewski, co-host of Defense in Depth.

Automated attacks are growing in speed and sophistication, far outpacing the human defenses most organizations rely on. Whether it’s credential stuffing, scraping, or denial-of-wallet attacks, bots can drain your resources before they even steal a cent.

In this episode, Sam Crowther, founder of Kasada, discusses how their bot detection and mitigation solution flips the economics of attacks. By disrupting automated behavior at wire speed—without impacting user experience—Kasada ensures you’re doing business with real people, not fake clicks. Joining him are panelists Jimmy Sanders, president of ISSA International, and Jason Elrod, CISO at MultiCare Health System.

Managing privileged access across a sprawling IT environment remains one of cybersecurity’s toughest balancing acts. Admin privileges are often granted too broadly and retained for too long, opening dangerous pathways for lateral movement and ransomware.

In this episode, Rob Allen, chief product officer at ThreatLocker, introduces their Elevation Control tool — a solution designed to help security teams remove unnecessary privileges, apply just-in-time elevation for specific apps, and restrict lateral movement, even within elevated sessions. Joining him are Mike Woods, vp of cybersecurity at GE Vernova, and Steve Zalewski, co-host of Defense in Depth.

Security operations centers (SOCs) are drowning in alerts, forcing analysts to waste time chasing down false positives while real threats slip through. The problem isn’t just efficiency—it’s burnout, missed signals, and limits on what security teams can reasonably triage.

In this episode, Edward Wu, CEO and founder of Dropzone AI, explains how their AI-powered SOC analyst automates triage and investigation for security alerts. The result is more efficient operations, faster detection of real threats, and a significant reduction in alert fatigue. He’s joined by our panelists, TC Niedzialkowski, head of IT and security at Opendoor, and Steve Zalewski, co-host of Defense in Depth.

Securing endpoints is a persistent challenge, especially in a hybrid working environment. The human factor is an unavoidable element with endpoint security, which means you have to be ready for a lot of unexpected behavior. Centrally managed policies for endpoints can only enhance security if they don’t compromise the flexibility the business needs.

In this episode, Rob Allen, chief product officer at ThreatLocker, discusses how their Network Control solution offers a endpoint-based firewall to protect these devices. Rob is joined by our panelists, Janet Heins, CISO at ChenMed, and Shaun Marion, vp, CSO at Xcel Energy.
