Alerts

Act now alerts

One feed at a fixed address, rebuilt every time the pipeline runs, roughly every 3 hours. A record becomes eligible on the first successful run that observes its move into Act now or its addition to the Cybersecurity and Infrastructure Security Agency Known Exploited Vulnerabilities catalog, and each title opens in square brackets with the record's tier, or with a note that no tier is assigned yet. Point a reader at it, a Slack channel through Slack's RSS app, or a Microsoft Teams channel through a Teams Workflow (see integrations). There is no email version of this feed; it does not send email.

The feed carries the current comparison window, so an entry can leave it as little as one pipeline pass after it appears. Poll it at least as often as the site publishes, and do not treat it as an archive. The changes page shows the current comparison too; neither preserves every alert previously emitted.

The static feed keeps the newest 50 alerts. For the complete current window, use Act now and KEV alerts. The My Stack alerts link on the home page adds changes matching your pinned vendors. Direct Slack and Teams webhooks use operator-configured destinations and vendor lists; pinning in your browser does not configure a webhook or upload your pins.

Capability matrix

What each access method gives you. Unknown means we have not measured that limit.

Current reader and machine-access capabilities
Capability	Account required	Filters	How often it updates	Format	Limits
Read in browser	No	Global full-text search; page-specific filters vary.	New deploys follow the combined news-first data pipeline every 3 hours.	HTML pages	unknown (no site-wide result limit is documented)
RSS/OPML	No	Categories, personas, and vendors; Save this view pairs a table's share link with its matching RSS feed where source permissions allow; OPML exports all or selected directory feeds.	Static RSS cache: 5 minutes. Custom RSS cache: 15 minutes.	RSS 2.0 and OPML 2.0	Static feeds: 50 items; custom feed: 60 items; saved views: all matching rows in that page's published data window (a Patch Day month too large for one feed carries its newest entries and says so in the feed); vendor directory: top 200 vendors.
JSON API	No key or account	No server-side query filters; choose the documented static shards and paths.	5-minute cache; data republishes on the combined 3-hour deploy schedule.	JSON over HTTPS GET	No hard rate limit; documented guidance is at most 1 sustained request per second.
Email	No site account; a confirmed email address is required.	One Daily Brief list; up to 15 vendor pins. Mondays fold in the Weekly Recap.	Every day at 07:00 ET; Monday's edition also carries the Weekly Recap, at the same time.	HTML and plain-text email	Up to 5 top picks and 5 stories per category; up to 15 vendor pins.
Slack/Teams	A Slack workspace or Microsoft Teams tenant is required.	Choose a tracker RSS feed, or use operator-configured webhooks for Act now, new KEV and configured vendor hits.	Third-party poll interval: unknown; tracker cache is 5 minutes for static RSS and 15 minutes for custom RSS.	Channel posts from the Slack RSS app or a Teams Workflow; direct alert webhooks require operator configuration.	Tracker feed window: 50 static or 60 custom items; third-party posting limit: unknown.
MCP	No	Tool-specific text, status, tier, actor, breach, exploit, and date filters.	Reads the currently deployed public shards on each call; shard publication follows the pipeline deploy schedules.	Stateless JSON-RPC 2.0 over HTTPS POST with application/json	20 default and 100 maximum rows; 60 requests per minute per caller; 32,768-byte request body.
