Safeguarding LLM-Assisted Dev at Guardsquare

New blog post discussing Guardsquare's approach to using large language models (LLMs) in development, highlighting security considerations for a cybersecurity company handling sensitive IP.

Use P2C + EWMA for High-Throughput Java Routing

A technical article demonstrating that traditional round-robin load balancing performs poorly for high-concurrency Java virtual thread workloads. The author recommends using the Power-of-Two-Choices (P2C) sampling algorithm combined with an Exponentially Weighted Moving Average (EWMA) latency metric to compute a real-time health score per instance: Score = (Active Virtual Threads + 1) × EWMA Latency. The post includes a Java code snippet implementing a P2C selector and argues this approach reduces p99/p999 tail latency and avoids synchronization costs inherent to full-node scans or naive least-connections strategies.

• Java virtual threads allow microservices to handle ~50,000 concurrent requests per instance (as asserted by the author).
• Legacy round-robin load balancers can degrade p99 latency when servicing virtual-thread workloads due to head-of-line blocking.
• The recommended routing policy is Power-of-Two-Choices (P2C) sampling of two instances plus a health score computed as (Active Virtual Threads + 1) × EWMA Latency.

Community Poll: Do You Test AI Agents for Prompt Injection?

A Dev.to community post by Brij Purswani (published 2026-07-07) asks developers whether they test AI agents for prompt injection and adversarial inputs. The author, who builds security tools for AI agents, reports having spoken with roughly 200 developers and says most admitted they do not test for adversarial prompts. The post lists poll options (A: I test, B: I know I should, C: I didn't know, D: Not sensitive) and links to a quick scan tool (sec-ra.com) for testing agents. The piece is a discussion prompt rather than a technical guide or policy announcement.

• Author Brij Purswani published the post on Dev.to on 2026-07-07.
• The post asks whether developers test AI agents for adversarial inputs such as prompt injection, system prompt extraction, or unauthorized tool/data access.
• The author says he has talked to about 200 developers and that most answered 'no' to testing for adversarial inputs.

NewsGuard Launches NewsGuard AI in Europe, Bringing Reliable AI-Powered News to European Readers in French, German, and Italian, in addition to English

NewsGuard has launched NewsGuard AI in Europe, expanding its AI-powered news service to French, German, and Italian, in addition to English. This marks a significant product launch for the company.

NewsGuard AI Launches in Germany, Austria, and More European Countries

NewsGuard has launched its AI service, NewsGuard AI, in Germany, Austria, France, Italy, the UK, and other European countries. The AI tool answers questions on current news topics using only approximately 12,000 news sources that NewsGuard has vetted for credibility and transparency. When journalistic content is used in responses, NewsGuard AI cites and links to the original articles, and the media outlets receive compensation. The service is subscription-based, with a free tier of ten queries per day and a premium subscription at eight euros per month after a two-week free trial. NewsGuard has no plans to introduce advertising. Publishers can participate as co-marketing partners, offering the service to their readers at a discounted rate and receiving 50% of the subscription revenue generated through their channels. This creates a potential indirect advertising effect, as frequently cited sources might leverage the credibility label for brand safety.

• NewsGuard AI launched in Germany, Austria, France, Italy, and the UK.
• The AI service is based on around 12,000 vetted news and information sources.
• Publishers receive compensation when their content is cited in AI responses.
