Runtime guardrails inside your app: what library-level protection catches that a WAF can't
A WAF sees a request, not the SQL query it turns into. How query-structure SQL checks, SSRF checks on resolved IPs, LLM and MCP guardrails, Monitor mode and fail-open work inside the application.
Writing an MCP Server That Holds No Credentials
Give a model a tool that writes and you have added a route into whatever sits behind it. The design that keeps it a new shape rather than a new privilege, and the four things that were not obvious.
You Cannot Defend an MCP Server You Do Not Know You Are Running
Tool poisoning is the most impactful client-side MCP vulnerability, and the defensive research is solid. All of it assumes you know which MCP servers you connect to. Almost nobody does.
MCP Spec 2025-11-25: Tasks, URL Mode Elicitation, and What Defenders Must Watch
The November 25, 2025 Model Context Protocol release adds Tasks, formalises long-running work, and reshapes the audit story for enterprise MCP.
Gold Open Source: A Free Directory for the Whole Supply Chain — Now in Your Browser
Gold Open Source is Safeguard's free, no-login directory of security-verified open-source software. It now covers AI models, MCP servers, agent skills, chip manufacturers, and the full MITRE ATT&CK framework — and ships as a Chrome extension.
What's New: Live Agentic Search, a Real Trust Center, and Safeguard in Your Browser
A tour of this month's releases — watching Griffin work in real time, publishing your security posture and artifacts to a governed Trust Center, and reaching Safeguard from the browser, CLI, IDE, and MCP.
The Security Chores Agents Should Handle Themselves
Enabling 2FA, rotating a password, revoking a stale session, minting a scoped key — the account-hygiene tasks everyone postpones. When an agent can do them through MCP, 'later' becomes 'now.'
Region-Blind Pricing Breaks the Moment an Agent Checks Out
Your pricing is localized by country — but an AI agent rarely holds a clean country code. If your checkout can't resolve region from the messy signals an agent actually has, it quotes the wrong price or none at all.
Death by a Thousand Tools: Governing an MCP Server at Scale
A 900-tool MCP server is powerful and terrifying in equal measure. The answer isn't fewer tools — it's per-tenant governance, where each capability is off until an admin turns it on.
The Onboarding Tax: Why Signup Forms Break Agent Workflows
Every signup form, verification email, and OAuth redirect is a wall an AI agent can't climb. Zero-touch onboarding lets an agent create the account and sign in itself — no browser, no human relay.
Scanning AI-Generated Code Before It Merges: Wiring Scanners into Coding Assistants with MCP
Research found ~40% of Copilot suggestions were vulnerable, and devs using AI assistants trusted their code more. MCP lets you scan before merge.
AI agents in AppSec pipelines: triage, remediation, and guardrails
GitHub's Copilot Autofix cuts median fix time from 1.5 hours to 28 minutes — but a 2025 Replit agent incident shows why autonomy needs hard limits.
Self-healing security runs on Safeguard.
Your first fix PR is minutes away.
No sales call required, even your agent can complete the purchase over MCP.
