Methodology

The CloudySec Digest is a weekly editorial brief produced by an AI-assisted pipeline at CLOUDYRION GmbH. We do not republish articles. We crawl public security feeds, write our own short summaries, and link to the original publisher. Every summary on this site has been generated under the rules described below; every story has a single, verifiable source link.

Each issue draws on more than fifty public sources: official agencies (BSI, ENISA, CISA, NCSC, ANSSI), vendor security research (Mandiant, Microsoft, Project Zero, Unit 42, and others), and specialist trade press. We do not crawl behind paywalls, do not re-syndicate from other aggregators, and do not summarise content obtained via subscription-only feeds.

Sources are classified internally by type. The classification governs how a story is treated:

Class A — Official / public-domain

Government and supra-national advisories (BSI, CISA, ENISA, EU Commission). Free quoting permitted. Aimed at the bulk of the issue mix.

Class B — Open-licensed

Material under Creative Commons or equivalent, used in accordance with the licence terms.

Class C — Vendor security research

Vendor blogs and threat-intelligence write-ups. Summarised analytically, with the original linked as the canonical source.

Class D — Tier-1 press

Major news publishers covered by ancillary press-publisher rights (§§ 87f–87h UrhG, DSM Art. 15). By default we publish headline plus link only and do not generate a summary. Where a summary is essential to the brief, it is approved manually by the responsible editor.

Class E — Aggregators / forums

Not summarised. Treated as discussion signal only.

Summaries are produced by Anthropic Claude (Sonnet) running under a fixed editorial prompt maintained by CLOUDYRION. The prompt instructs the model to write an analytical brief in its own words, not a paraphrase of the source, and to add value beyond the headline (context, risk framing, comparison, implications for European enterprise).

The model is constrained to take at most a short consecutive excerpt (seven words) verbatim from any single source, and only for unavoidable terms — proper nouns, product names, CVE identifiers, attributed quotations. Everything else is the publication’s own formulation.

AI recommendations.For sources we summarise, the assistant also drafts a short “why it matters”, a suggested enterprise action, and an optional board-level brief. When you read on a specific desk, the “why it matters” and suggested action may be framed for that desk’s remit. These are forward-looking interpretations generated by the model, not reproductions of the source, and they pass the same copyright check (Layer 4) as summaries. They are never generated for Tier-1 press (Class D) or aggregator / forum (Class E) sources.

Selection and summarisation are produced by AI under editorial oversight at the desk that publishes the issue. The AI involvement is disclosed on every article page.

Every article on this site links out to the original publisher and opens the source in a new tab. We do not host article bodies, do not bypass paywalls, and do not pre-fetch external pages on the reader’s behalf. A summary on this site is intended as decision support — to help a CISO triage the week — not as a substitute for reading the original.

Our crawler identifies itself as CLOUDYRION-Ezine in its User-Agent string. It respects machine-readable opt-out signals for text-and-data-mining (Art. 4 DSM Directive, § 44b UrhG):

• robots.txt — both site-wide rules (User-agent: *) and rules naming our crawler specifically (User-agent: CLOUDYRION-Ezine). Granular blocks of other AI crawlers (e.g. GPTBot, Applebot-Extended) are read as the publisher’s specific concern with those actors and do not stand in for an opt-out of our distinct editorial use. Publishers who want our crawler excluded can block * or name us directly; either is binding.
• /ai.txt and /llms.txt files where published.
• HTTP X-Robots-Tag response headers (noai, noimageai) and the W3C tdm-reservation: 1 header on feed URLs.

Per-host checks are cached for seven days. A source that opts out is removed from the crawl set on the next pipeline run; we continue to be free to link to it as a hyperlink reference, but no content from that site is ingested or summarised.

We are lenient on fetch failure: if robots.txt cannot be reached at all (network error, malformed response), we proceed rather than treating the absence of a signal as an opt-out. Explicit opt-out signals always win, regardless of fetch state.

For every published item we retain — internally, never published — the source URL, the time of crawl, the model and prompt version used, and a hash of the source text at the time of summarisation. We do not store full source texts. These records exist to allow us to reconstruct the editorial process for any single item if a rightsholder, source, or named subject asks.

AI-assisted writing makes mistakes. If a summary on this site is inaccurate, misattributed, or misleading, we want to know. Write to editor@cloudyrion.com and we will correct or remove the item.
