The trinity of ‘developer experience + security standards + operational efficiency’ is greater than the sum of its parts. We call it ‘ergonomic cybersecurity’.
We were just assigned a /29 #IPv6 block by RIPE. We now have 633,825,300,114,114,700,748,351,602,688 IPv6 addresses.

Sponsoring the local #Rust meetup in #Cambridge is way we bring the community together a few times a year. Follow the event page at https://www.meetup.com/cambridge-rust-meetup/ and https://mastodon.social/@cambridgerust here.
Rust has played a critical role in the cloud security solutions we ship in terms of speed, stability & safety.
What data do coding agents send, and where to?
Our report seeks to answer some of our questions for seven of the most popular agentic code editors and plugins. By intercepting and analysing their network flows across a set of standardised tasks, we aim to gain insight into the behaviour, privacy implications, and telemetry patterns of these tools in real-world scenarios. Incidentally, a side-effect was running into OWASP LLM07:2025 System Prompt Leakage for three of the chosen coding agents. You can see the system prompts in the appendix.

Welcome to the team Lucas Pye! Lucas is joining us as an intern until mid-September and is researching what telemetry is gathered from developer machines by various popular agentic coding tools. When he's not intercepting #egress traffic you can find him climbing in the Peak District or his local gym.

TLS ECH (formerly ESNI) is an emerging threat in traffic observability.
Learn about what it is, its background and original purpose, and how to disable it in controlled environments - especially Chrome and headless Chrome in the linked solution article:
