AI Guardrails: The Layer Between Your Model and a Mistake

An AI guardrail failure doesn’t come with a warning. One minute, a response goes out. Next minute, it’s a screenshot in the wrong hands, and the question isn’t how it happened. It’s why nobody had defined what the model was allowed to do in the first place. Most teams never asked what the model was actually permitted to do. Deployment happens fast. AI data privacy and leakage prevention aren’t configuration tasks.

Baking accessibility into our product foundation

TL;DR: Building for everyone, faster. We’re moving from the why to the how. To scale accessibility without losing speed, we’ve overhauled our foundation: In our previous post, we explored why accessibility is a non-negotiable for modern cybersecurity. But moving from philosophy to practice required a fundamental shift in our toolkit.

AI Security Best Practices: The Complete Guide

Artificial intelligence has moved from pilot project to core enterprise infrastructure faster than most security programs can adapt. AI is automating workflows, surfacing insights from complex datasets, and changing how work gets done across every function. But with that acceleration comes a new and expanding attack surface that most organizations are only beginning to understand.

Synthetic Data for AI: 5 Reasons It Fails in Production

Synthetic data for AI development has become the default shortcut for most engineering teams. It’s fast, sidesteps privacy headaches, and lets you move without touching production. I get why teams default to it. But there’s a problem: synthetic data for AI routinely breaks down the moment your system hits real-world enterprise data. The system demos great. It passes every internal test. Then it lands in production and falls apart in ways you didn’t see coming.

Joiners, Movers, and Leavers (JML): What It Is, & Why It Matters

Modern organizations frequently onboard new employees, manage internal role changes, and handle departures across multiple business applications. Without a structured identity lifecycle, access requests become manual, inconsistent, and difficult to track. This directly affects security, operational efficiency, and audit readiness. A defined JML process in IAM ensures that the right users receive the right access at the right time while reducing administrative overhead.

Closing the gaps in your identity lifecycle management strategy

A lot happens during a user’s identity lifecycle. However, many organizations don’t always ensure user identities are securely created, removed and managed. There are also the risks around compliance violations, insider threats, lower productivity and higher costs from managing sprawling and complex environments. That’s why it’s business-critical to deliver holistic identity lifecycle management (ILM).

Cato CTRL Threat Research: Vishing and Microsoft Teams Used to Deliver PhantomBackdoor

Cato CTRL has discovered a q-based delivery technique used against an Italy-based consumer services company associated with PhantomBackdoor, a multi-stage WebSocket-based backdoor previously reported in a Ukraine-focused spear phishing operation by SentinelOne. In SentinelOne’s earlier reporting, initial access relied on phishing lures and a ClickFix-style flow that triggered a staged PowerShell and ended with a WebSocket backdoor.
