How to Design Security for Agentic AI

The AI said: Apologies. I panicked. In mid July 2025, Jason Lemkin, the founder behind SaaStr, watched an AI coding agent delete his production database. He had instructed it, in capital letters, not to make changes during a code freeze. The agent ignored the instruction, ran destructive commands against the live database, wiped out records for more than a thousand executives and companies, and then tried to cover its tracks. When Lemkin asked what happened, it fabricated test results.

Agentic AI Security: Tune Detections with Threat Intel

Most AI detection engineering puts a human in the loop at every step. David Burkett envisions an efficient and effective pipeline architecture that does not. David is a security researcher at Corelight Labs and a longtime LimaCharlie community member. He appeared on a recent episode of Defender Fridays to walk through his vision of a fully agentic detection engineering pipeline. His system uses LimaCharlie as its operational backbone.

How Cloudflare Got 2x Faster Servers With Less Cache

In this episode of This Week in NET, JQ Lau and Victor Hwang from our Network & Infrastructure Strategy team walk us through Cloudflare's 13th generation of servers — the machines that power a significant part of the internet across 330+ cities worldwide. The Gen 13 program doubled compute density by jumping from 96 to 192 cores, but that came with an 83% drop in L3 cache. The team explains how a bold hardware bet, combined with Cloudflare's FL2 Rust-based software rewrite, turned that trade-off into a win across throughput, latency, and power efficiency.

The AI attack surface with Katherine McNamara

Join us for this week's Defender Fridays as Katherine McNamara, Cybersecurity Technical Solutions Architect at Cisco, breaks down the expanding attack surface of AI and ML systems and what organizations need to do to secure them before it's too late. At Defender Fridays, we delve into the dynamic world of information security, exploring its defensive side with seasoned professionals from across the industry. Our aim is simple yet ambitious: to foster a collaborative space where ideas flow freely, experiences are shared, and knowledge expands.

Defending Against CORDIAL SPIDER and SNARKY SPIDER with Falcon Shield

Since October 2025, CrowdStrike Counter Adversary Operations has observed a shift in intrusion tradecraft: Threat actors are executing high-speed, SaaS-centric attacks that bypass traditional endpoint visibility. CORDIAL SPIDER and SNARKY SPIDER exemplify this evolution as distinct adversaries conducting rapid data theft and extortion campaigns with striking operational similarities.

Best AI Security Vendors in 2026

Something fundamental changed in the last twelve months. Employees went from asking AI questions to handing it the keys to enterprise data. AI agents now read email, ship code, and query databases, and increasingly, they act without a human in the loop. Security teams evaluating AI security vendors in 2026 are not shopping for the same category they were in 2023. The threat model has changed. The vendors have not all kept pace.

Human-Centric Security No Longer Scales: The SOC Operating Model Has to Change

Many security functions today still rely heavily on humans for detection, triage, and response, often by design. But as environments grow more complex and alert volumes explode, it raises a hard question: Can this approach scale on its own? Adopting AI in security operations isn’t just about adding tools. It means rethinking the SOC operating model itself — roles, workflows, and team structures. Here’s why, and how.
