Interview with Harish Peri from Okta Oktane Preview: building frameworks to secure our Agentic AI future Like it or not, Agentic AI and protocols like MCP and A2A are getting pushed as the glue to take business process automation to the next level. Giving agents the power and access they need to accomplish these lofty goals is going to be challenging, from a security perspective. How do put AI agents in the position to perform broad tasks autonomously without granting them all the privileges? How do we avoid making AI agents a gold mine for attackers - the first place they stop once they hack...

Segment 1: Interview with Monzy Merza - There is a Right and Wrong Way to use AI in the SOC In the rush to score AI funding dollars, a lot of startups build a basic wrapper around existing generative AI services like those offered by OpenAI and Anthropic. As a result, these services are expensive, and don't satisfy many security operations teams' privacy requirements. This is just the tip of the iceberg when discussing the challenges of using AI to aid the SOC. In this interview, we'll dive into the challenge of finding security vendors that care about security, the need for transparency in...

Single Sign On (SSO) and Multi Factor Authentication (MFA) is critical to secure operations for companies of all sizes. Why is the foundation of cybersecurity still locked behind enterprise licensing? Single Sign-On (SSO) and Multi-Factor Authentication (MFA) are essential—not optional—for protecting modern businesses. But today, these critical tools are overpriced, overcomplicated, and reserved for companies that can afford to overpay and have full-time security teams. That’s broken. Cubeless is tearing down the barriers. With Cubeless Verify, we’re delivering SSO and MFA that anyone...

Default deny is an old, and very recognizable term in security. Most folks that have been in the industry for a long time will associate the concept with firewall rules. The old network firewalls, positioned between the public Internet and private data centers, however, were relatively uncomplicated and static. Most businesses had a few hundred firewall rules at most.

The idea of implementing default deny principles elsewhere were attempted, but without much success. Internal networks (NAC), and endpoints (application control 1.0) were too dynamic for the default deny approach to be feasible. Vendors built solutions, and enterprises tried to implement them, but most gave up.

Default deny is still an ideal approach to protecting assets and data against attacks - what it needed was a better approach. An approach that could be implemented at scale, with less overhead. This is what we’ll be talking to Threatlocker’s CEO and co-founder, Danny Jenkins, about on this episode. They seemed to have cracked the code here and are eager to share how they did it.
