Affordable Vulnerability Digest Replacing CISA's Bulletin is a startup idea for security teams, sysadmins, and MSPs. CISA announced it is ending its free weekly vulnerability bulletin while moving to risk-based prioritization, leaving many small teams without a source they used for years. A thread in r/cybersecurity drew 117 upvotes and 10 comments between Sep 14, 2026 – Oct 14, 2026. People get by with NVD feeds, Recorded Future, and Vulners, and that still leaves this job open. Hotness is 3.35, Warm. Real but moderate pain. Some willingness to pay. The thread drew 117 upvotes and 10 comments. Only clumsy or enterprise-only options. Buildable in days. A first version is weekend-easy, about 1 week, priced between $10 and $49 a month and charged as a subscription. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

A way through
A lightweight, affordable vulnerability digest for small security teams that can't pay for Recorded Future/Mandiant-class platforms.
MVP scope
- Give security teams, sysadmins, and MSPs a way to do this in one sitting: A low-cost weekly vulnerability digest for small security teams losing the free CISA feed.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a subscription, between $10 and $49 a month. The free path must finish the core job once.
- Ship the newsletter only. Leave NVD feeds to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use NVD feeds, Recorded Future, Vulners. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 1 weeks (1 week), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is security teams, sysadmins, and MSPs. Charge a subscription, and test a price between $10 and $49 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
