SentinelOne Purple MCP: A Hands-On Guide to Singularity AI Integration

Every technical support team I have worked with shares the same friction point: an analyst keeps four tabs open simultaneously (the EDR console, a ticketing system, an asset CMDB, and a query window) and spends a sizeable chunk of their shift copy-pasting IDs between them. The intelligence exists. The problem is getting it out fast enough. The Model Context Protocol (MCP) is the most credible attempt I have seen yet to reduce that cost. It is a small, open specification for letting LLM-driven assistants invoke external tools in a typed, structured way: a server exposes a catalogue of tools with JSON Schema input contracts, and any MCP-aware client (Claude Desktop, Claude Code, Zed, or your own automation) can call them without writing any glue code. One server definition, every compatible client for free. ...

The Challenge of Securing AI Agents: A DevSecOps Perspective

As a DevSecOps Team Leader, my job is to secure customers using modern technologies. Sounds straightforward, right? The reality is far more complex. Every day, I face the challenge of enabling innovation while maintaining security. The rapid adoption of AI has introduced a new dimension to this challenge: agentic AI assistants that do not just chat, they act. This challenge connects directly to something I wrote about recently. In my article on spec-driven development with GitHub Spec-Kit, I discussed how structure and governance matter when using AI for coding. The same principle applies here: when AI agents can execute code, access secrets, and operate with user privileges, we need structure and governance more than ever. ...

Docker Hardened Images Are Now Free and Open Source

I’ve already touched the hardened images theme in the past talking how this theme is important in today’s world. Reducing the attack surface of our containers is not just a “nice to have” anymore; it is a fundamental requirement for a secure software supply chain. In an era where vulnerabilities can be exploited within hours of disclosure, starting with a secure base is half the battle. That is why the recent move by Docker is so significant. ...

Securely Working with Third-Party MCP Servers

In the rapidly evolving landscape of AI and large language models (LLMs), the ability to connect these models to external tools and data sources is crucial for building powerful, automated applications. The Model Context Protocol (MCP) has emerged as a standard for this purpose, but its use also introduces new security challenges. This article explores how to work securely with third-party MCP servers, drawing insights from the recently released OWASP GenAI security cheatsheet. ...
