Testing Prompt Guard: What It Is, Why It Matters, and How to Evaluate It May 13, 2026
Prompt injection is a core security problem for LLM applications. This post explains what Prompt Guard is, why filtering untrusted input matters, and how to test classifiers with realistic benign, malicious, and borderline datasets—not only obvious jailbreak strings.
LLM Guard Testing: Guard vs Prompt Guard May 1, 2026
This post is about testing the protection layer around an LLM system.
AI in Test Automation for Software Development in 2026 Apr 29, 2026
AI is becoming a normal part of software testing, but it is not a replacement for test strategy, product judgment, or engineering review. In 2026, the strongest use of AI in test automation is as an accelerator: it helps teams create first drafts of tests, prioritize risk, debug failures, summarize evidence, generate test data, and maintain suites that would otherwise become expensive and brittle...
