Indirect Prompt Injection Stopped Being a Demo. Google Is Measuring It at Web Scale.
Malicious injected instructions are now tracked across billions of crawled pages a month, every AI browser tested at Black Hat proved vulnerable, and one framework bug turned a prompt into RCE.
ChatGPT Atlas and the Permanent Browser-Agent Injection Problem
OpenAI shipped ChatGPT Atlas in October 2025 and admitted by December that prompt injection in AI browsers may never be fully solved. Defenders need a posture, not a patch.
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.
Every AI Coding Tool Has the Same Vulnerability, and It Isn't a Bug
Sandbox escapes in Claude Code, critical CVEs in Cursor, a 10.0 in Gemini CLI, prompt injection in Copilot. Different vendors, one shared cause: the agent must hold elevated access to be useful.
Security risks of multi-agent AI systems collaborating au...
Multi-agent AI systems introduce security risks classic AppSec misses: agent-to-agent exploits, swarm failures, and orchestration trust gaps.
Security implications of AI browser agents that click, br...
AI browser agents click, browse, and pay with your credentials -- and prompt injection attacks like EchoLeak and CometJacking prove they can be hijacked to do it.
Securing computer-use AI agents that operate desktops and...
Computer-use AI agents can click, type, and log into any app on your desktop. Here is how computer use AI agent security actually works in practice.
Explaining Model Context Protocol and its expanding attac...
MCP security is now urgent: MCP servers grew from 700 to 16,000+ in a year, and most are unaudited. Here is the threat model and how Safeguard secures it.
How tool poisoning attacks compromise MCP tool descriptions
A single poisoned tool description can turn a trusted MCP server into a silent data-exfiltration channel. Here's how these attacks work — and how to stop them.
Explaining prompt injection attacks and why they're hard ...
Prompt injection attacks trick AI models into obeying attacker instructions hidden in data or user input, and there's still no complete fix.
How indirect prompt injection hides malicious instruction...
How attackers hide malicious instructions inside webpages, documents, and retrieved content to hijack AI systems — and why RAG pipelines are especially exposed.
Comparing LLM firewall and guardrail products for enterpr...
A vendor-by-vendor comparison of LLM firewall and AI guardrail platform options for enterprise deployment, with real strengths and limitations for each.
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.
