Introducing RAMPART and Clarity: Open source tools to bring safety into Agent development workflow

In this article Why we are investing in this RAMPART: Continuous safety testing for agentic AI Clarity: Helping check software engineering assumptions RAMPART and Clarity available now The AI systems shipping inside enterprises today are fundamentally different from the ones we were building even two years ago, because they have moved well past answering questions and into accessing your email, retrieving records from your CRM, writing and executing code, and taking actions on your behalf across dozens of connected systems. That shift from “generate text” to “do things in the world” changes the safety equation entirely, because an agent that can act can also potentially act in ways nobody intended. Today Microsoft is open-sourcing two tools designed to help engineers: Microsoft RAMPART , an agent test framework for encoding adversarial and benign scenarios as repeatable tests that can run in CI, making it easy to turn red-team findings and AI incidents into lasting regression coverage; and Clarity , a structured sounding board that helps teams figure out whether they are building the right thing before they write a single line of code. We built these tools because we believe that AI safety has to become a continuous engineering discipline rather than a periodic checkpoint, and we think the best way to make that happen is to put practical, open tools in the hands of the people doing the building. Why we are investing in this Helping teams think through the “why,” before the “how” of software building: In the vibe coding era, execution is easy and the harder question is the “why.” The most expensive safety failures we see almost always trace back to design mistakes that nobody questioned early enough, long before any adversary got involved — say, when a product team decided their agent should have access to a tool, or handle a particular user flow, without fully working through what could go wrong. By the time a red team engagement surfaces the issue, the system is largely built, and addressing it means going back to the drawing board. We wanted to give product managers and engineers a way to pressure-test their assumptions at the start of a project, when changing course is cheap and the right conversation can save months of rework. Scaling the lessons of red teaming across the industry. The techniques that uncover vulnerabilities in one agentic product almost always shed light on another. A cross-prompt injection attack that works against one system will often work, with minor variations, against a customer service agent or a coding assistant. But those lessons tend to stay locked inside individual engagement reports. Our goal was to build a system where the lessons of red teaming exercises can be turned into runnable engineering assets. Making incidents reproducible and mitigations verifiable. If something goes wrong in production AI systems, the team responding needs to do two things quickly: replicate the incident

The tech giant attributed the activity to a threat actor it calls Fox Tempest, which it said offered the MSaaS scheme

On AI Security

Good report : Executive Summary: Let’s say you wanted to make sure that your AI is secure. Can you just maximize the security and privacy benchmark and call it a day? Nope, because benchmarks don’t actually work for measuring AI capabilities (even when they are NOT emergent systemic properties like security). So let’s take a step back: how do you measure security in the first place? Good question. Over the last 30 years, security engineering for software evolved from black box penetration testing, through whitebox code analysis and architectural risk analysis to de facto process-driven standards like the Building Security In Maturity Model (BSIMM). Software had a very deep impact on business operations, and it appears that AI is going to have an even deeper impact. Will a software security-like measurement move work for AI? Probably. In the meantime we can make real progress in AI security by cleaning up our WHAT piles and managing risk by identifying and applying good assurance processes. (Spoiler alert: no matter what we do, we still don’t get a security meter for AI, so we need to be extra vigilant about security.)

Operationalizing CTEM Faster: Build Surface Command Dashboards in Minutes

Modern attack surfaces don’t sit still. Cloud expansion, SaaS sprawl, identity complexity, and shadow IT are continuously reshaping organizational risk. For security leaders, visibility isn’t the challenge anymore, but actually operationalizing that visibility is. Surface Command was built to unify asset and identity intelligence across your external attack surface. But translating that intelligence into executive-ready dashboards or operational reporting has often required knowledge of Cypher queries. Today, that changes: We’re introducing filter-based dashboard widgets in Surface Command, enabling teams to build meaningful attack surface management (ASM) dashboards in minutes, without writing a single query. And for CISOs focused on advancing continuous threat exposure management ( CTEM ), this is more than a usability enhancement. It’s an operational accelerator. From filters to dashboards, instantly Security teams already use saved asset and identity filters to answer critical questions: Which internet-facing assets are high risk? Where do privileged identities intersect with exploitable exposures? Which business units own unmanaged cloud infrastructure? What third-party SaaS applications expand our attack surface? Now, those same saved filters can be converted directly into live dashboard widgets. If your team can build a filter table, they can now build a dashboard. There’s no need to understand query syntax or rely on specialized expertise for common reporting needs. With just a few clicks, exposure views become shareable, persistent dashboards built on the same unified data model that powers Surface Command. Figure 1: Creating dashboard “widgets” in the Rapid7 Command Platform Reducing friction in exposure reporting For many organizations, the barrier to effective exposure management isn’t visibility, it’s friction. When dashboard creation requires query expertise, reporting slows down, operational teams depend on a small group of power users, executive visibility lags behind exposure reality, and CTEM initiatives stall under complexity. Filter-based widgets remove that bottleneck. Security teams can now spin up exposure dashboards in minutes, empower analysts and vulnerability teams to self-serve, deliver consistent reporting to leadership, and standardize exposure views across business units. This lowers the barrier to building and maintaining exposure intelligence across the organization, and that matters when “continuous” is the goal. A practical enabler for continuous threat exposure management (CTEM) Beyond a framework, CTEM is a discipline. One that treats exposure management as an ongoing cycle, not a point-in-time project. CTEM is commonly organized into five continuous steps: Scope – Define what you’re focusing on (systems, business services, exposure themes, time horizons). Discover – Identify the assets, identities, and exposures within scope. Prioritize – Determine what matters most based on risk and impact. Validate – Confir
